THE EFFECT OF DETERGENT ON CHLOROPHYLLS CONTENT IN MICROALGA CHROOMONAS SAUNA (WILS.) BUTCH. (CRYPTOPH7TA) AND DYNAMICS OF ITS NUMBER

The effect of household synthetic detergent (HSD) "Tix" on growth and concentration of chlorophyll a in cryptophyte Chroomonas salina (Wils.) Butch, has been studied. It was shown that low concentration of HSD (0.05; 0.1 and 1.0 mg/L) stimulates growth of alga and has no influence on chlorophyll a content in the cells. At concentration 10 mg/L inhibition of growth and fission of cells is recorded, as well as morphological changes and blocking of chlorophyll a synthesis.

REGULATOR ROLE OF GLUCOSE IN METABOLISM OF SOME REPRESENTATIVES CYANOPHYTA

The effect of glucose on the growth and pigment composition of two cyanophytes, Spirulina platensis (Nordst.) Geifl. and Nostoc linckia (Roth.) Bom. et Flah. has been studied. It was revealed that they are able to conve rs e on mixotrophic growth. The increase of biomass in 2 - 5 times, and the repression of photosynthesis accompanied inclusion of glucose in metabolism of algae. The effect of glucose on pigment composition of studied algae was extremely different: glucose caused sufficient reduction of all pigments in S. platensis, while in N. linckia pigment composition did not reduced, and sometimes it even increased. The lowest pigment content in S. platensis was in the presence of 1% glucose at the 4-th day of growth: phycocyanine and chlorophyll decreased in 2-2.7 times, allophycocyanine and carotenoids in 1.7-2.0 times in comparison with control. It was found that conversion of S. platensis and N. linckia to mixotrophic growth results in excretion of coproporphyrine in the cultural medium. The assumption was made that glucose blocks biosynthetic way of tetrapirroles on coproporphyrinogene level, and light stimulates formation of earlier predecessors — g-aminolevuline acid.

EFFECT OF ULTRA-VIOLET RADIATION ON PHOTOMOVEMENT OF TWO SPECIES OF DUNALIELLA TEOD.

Experiments on studying the effect of ultra-violet (UV) radiation on photomovement parameters of two species of green alga of the genus Dunaliella Teod., D. salina Teod. and D. viridis Teod., had demonstrated that the velocity of translational movement of both species does not depend on the intensity and wavelength of UV radiation and duration of the irradiation, which is in contrast to phototopotaxis and the relative motility of the cells. This fact testifies to some possible difference in mechanisms governing these parameters of movement (velocity of forward movement on the one hand, and phototopotaxis and relative motility on the other hand) at the cell level. The conversion of positive phototopotaxis of algae into the negative under UV irradiation has been observed for the first time with further inhibition of phototopotaxis induced by increased duration of irradiation. The greatest inhibitory effect on phototopotaxis of algae is provoked by the radiation of 248-334 nm. The maxima of absorption spectra of proteins related to the motor apparatus and photoreceptor system of the alga are probably located here. The effect of UV radiation on photomovement of both species of Dunaliella had a reversible character: photo-orientation of the cells were restored to the control value at each wavelength (except 248 nm) in two hours after stopping of irradiation of 2 intensity. The dependence of phototopotaxis and motility of the cells of algae on the intensity, wavelength of UV radiation, and duration of irradiation testify to the possibility of using these algae as biotests of natural ultra-violet radiation.

ASSESSMENT OF TOXIC EFFECTS OF CUPROXAT FUNGICIDE ON PLATYMONAS VIRIDIS ROUCH. (CHLOROPHYTA)

The toxic effects of cuproxat fungicide on the algal culture Platymonas viridis Rouch. (Chlorophyta) were determined. The addition of 0.625; 1.25, and 2.5 mg/L of pesticide into the medium was accompanied by an increase in cell quantity at early growth stages (from 3 to 12 days). The optical density of the culture decreased with the addition of pesticide, as indicated by a fall of cell quantity, and its heat productivity increased at the beginning and at the end of the experiment as compared to the control. The pH of the medium changed insignificantly.

PHYCOPERIPHYTON ASSEMBLAGTS IN THE PINANG RIVER BASIN (MALAYSIA)

Epilithic, epipsamic, and epipelic algae were sampled at several locations along the Pinang River Basin. Periphytic algae attached on glass slides were also sampled to determine whether the artificial substrates were collecting representative samples of algal flora naturally present at a site, which were subsequently used in water quality analysis. The relative abundance of certain groups of algae was different on varying substrates. Natural substrates recorded higher densities of algae (947.32 on stones and 1314.36 on sediment). Comparative studies of the algal communities on different types of substrates are complicated. The mutual resemblances between artificial and natural substrates were 78.3% (stones and sands) and 78.1% (sediment). Although the substrate type influenced the algal composition, the occurrence of certain species in the Pinang River Basin was also determined by water quality. Glass slides as artificial substrate were useful to compare algal composition between sites with different levels of pollution and to reduce the heterogeneity of naturally occurring substrates, so that the difference in algal composition is due to water quality.

STUDY OF PECULIARITIES OF TAXOCENE STRUCTURE OF BENTHIC BACILLARIOPHYTA USING METHODS OF MULTIVARIATE STATYSTICS (LASPI BAY, THE BLACK SEA, UKRAINE)

Analysis of the structure of communities of benthic diatoms of Laspi Bay (the Black Sea, Crimea) has been done using methods of multivariate statystics. Two complexes of diatoms has been separated in taxocene: Navicula ramosissima Ag. + Licmophora gracilis (Ehr.) Grun. + Grammatophora marina (Lyngb.) Kutz. (complex I) and Tabularia tabulata (Ag.) Snoeijs (complex II). First complex is peculiar to the basic rocks of littoral zone (depth 0.5 m), the second is located at the depth over 3 m and consists of the central main body and marginal zone. Species – indicators and discriminators of mentioned complexes are identified. It was noted that complexes I and II have no distinct floristic margins, and stations located at similar depths but different types of substrates are floristically similar. Relative disposition and shape of domination-diversity curves of mentioned complexes of Laspi Bay reflect gradient of lowering of stress conditions of the habitat in direction: complex I – marginal zone of complex II – main body of complex II.

HEAVY METAL TOXICITY ON NITRATE REDUCTASE ACTIVITY OF FREE AND IMMOBILIZED ALGAL CELLS

Nitrate assimilation is the principal route for plants and algae to acquire inorganic nitrogen. Nitrate reductase is a multi-enzyme complex bound in the cell membrane in both active and inactive forms. Nitrate reductase is the limiting factor when considering the growth and protein production of algae. Heavy metals interacted negatively with the nitrate reductase (NR) enzyme activity of Chlorella vulgaris Beijer. Nickel was found to be more toxic compared to zinc and cadmium. A highly significant increase in NR activity was observed in the immobilized cells over free cells when supplemented with Ni.

LABORATORY BIOMODELS OF SULFURIC ALGAL-BACTERIAL MAT AND RINGS OF SULFUR (KARPOV'S RINGS)

Twointeresting sulfuric formations were studied in hydrothennal fields of the caldera of the Uzon Volcano (Kamchatka): (1) a sulfuric stratified algal-bacterial mat; and (2) horizontal rings of sulfur on the water surface (Karpov's Rings) formed near the growing colonies of blue-green algae (cyanobacteria). These formations are conditioned by the growth of blue-green algae (genera Oscillatoria and Phormidium belonging to the family Oscillatoriaceae) and the pulsating release of sulfur from hydrothermal springs. The biomodels obtained in the laboratory are similar in their morphology to the natural samples.

BACILLARIOPHYTA OF THE LOWER STREAM OF THE RIVER SOUTHERN BUG (UKRAINE)

The diatoms of Ihe river Southern Bug, water bodies of its basin and some lakes of Kinburn were investigated during August 2000 and 2001. 93 species of Bacillariophyta, represented by 98 infraspecific taxa, were found. 30 species were shown at first for the river Southern Bug and some water bodies of its basin. The comparison of the received data with literary testifies, that the taxonomic structure of Bacillariophyta is stable enough. The majority of the diatoms of the lower part of Southern Bug and water bodies of its basin make fresh-brackish, brackish-fresh, brackish, mesohalobic and euhalobic species. Among water saprobity indexes prevail a- and p-mesosaprobes. The richest species composition of the diatoms is revealed in phytoepiphyton. Similarity between the diatom lists of species in different biotops is low. The highest degree of floristic similarity have the diatoms of phytoepiphyton and phytobenthos. Species composition of Bacillariophyta of the mouth of the Southern Bug and the nearest water bodies precisely differs from those in the lower part of this river. Distance between stations has the greater value, than type of a water body.

ESTIMATION OF TAXONOMIC VALUE OF SOME MORPHOLOGICAL CHARACTERS OF UNICELLULAR GREEN FLAGELLATED ALGAE (VIRIDIPLANTAE) WITH COMMENTS ON MOLECULAR CLADISTICS

Some morphological characters of unicellular green flagellated algae inherent in their photosynthetic apparatus (plastids number, dimensions, localization, shape, structure of their outside and inside surfaces, pyrenoids presence or absence, pyrenoids number, localization, shape, structure of pyrenoid matrix and starch shirt surrounded it) were observed. In the distribution of diverse states of these characters in different trunks and branches and at various levels of phylogeaetic eukaryotic tree the numerous parallelisms were noted. This phenomenon limits the utilization of these characters in the systematics of higer taxa. Stable and hereditary at the species level these characters are used for identification of species and intraspecific taxa. Utilization of these characters at the superspecific levels stipulates an appearance of heterogeneous taxa, convenient for practice work. Their heterogeneity is confirmed by molecular data. There are no key characters outlining the groups of species within monophyletic clades at the molecular dendrograms. The clades recognized within Chlorophyceae by molecular methods do not correspond to any of the traditional classification systems. So the taxonomic revision of the traditional systems of unicellular green flagellated algae is untimly to-day. In advance it's necessary to realize three preliminary investigating stages at least: 1) to make clear why molecular dendrograms do not correspond to any of the traditional classification system at lower lewel; 2) to work aut the morphologycal-molecular species standart; 3) to find out key characters correlating with genotypic ones.

DYNAMICS OF PRODUCTIONAL AND MORPHOMETRIC INDEXES OF GRACILARIA THALLI IN THE CULTURE

Dynamics of productional and morphometric (diameter, length and number of brunches of all orders) parameters of the thalli of Gracilaria verrucosa (Huds.) Papenf. f. procerrima Esp. has been studied at temperatures 18°, 23° and 27°С, light intensity 30 and 40 . In 30 days of cultivation the average mass of thallus increased from 0.104 g up to 0.45 g of crude biomass. Maximal values of specific speed of growth of the thalli 0.068 and 0.069 are got at temperatures 18° and 23°C. At 27°C growth processes are substantially slowed. The temperature of environment is a factor determining strategy of morphological organization of thallus. At low temperatures, growth strategy of extensive type is realized through the increase of diameters and length of main axis and branches of 1st and 2nd orders. At the increase of temperature strategy of growth changes on the intensive way, namely, new branches of the second, third and fourth orders are formed.

ALGAL INDICATORS OF ENVIRONMENT IN THE NAHAL YARGON BASIN, CENTRAL ISRAEL

We recognized 247 species of algae from five divisions in 53 samples of plankton and periphyton collected at 14 stations over the Nahal Yarqon in 2003-2004. Of these, 204 species are indicators of environmental conditions. Species distribution over ecological groups is typical of alkaline freshwater or brackish, temperate, slow-running waters habitable for both planktonic and benthic algae. The indicators of saprobity (Watanabe's scale) show a medium level of organic pollution. The saprobity index S (Sladecek's scale) vary from 1.31 (the upper reaches) to 2.88 near the industrial area of Petakh-Tikva corresponding to II-IV classes of water quality. The self-purification capacity of the Nahal Yarqon ecosystem is rather high corresponding to the olgo- to alphamesosaprobic zones. The environmental pollution index (EPI) varies from 2 to 4 indicating a range of slightly to strongly polluted water of Class II and III. The Water Ecosystem State Index (WESI) testifies to a toxic impact on the algae in the low-water season. The River Pollution Index for saprobity ( = 2.3), conductivity ( = 2.0-2.7), nitric nitrogen ( = 1-8), and рН ( = 7.7-7.8) indicate alkaline moderately mineralized waters with an occasional input of nitrates round the year, corresponding to the Class III water quality and the betamesosaprobic self-purification zone. Our results allow an estimate of self-purification capacity for the Nahal Yarqon on the basis of modern international approaches. We provide indicators for evaluation and monitoring of the river. This study shows the potentials of the algal bioindication method for aquatic ecosystems of Israel.

FORMATION OF A SPECIES VARIETY OF THE PHYTOPLANKTON ON THE RIVER SITES OF THE DNIEPER RESERVOIRS

The features of formation of a species variety of the phytoplankton on the river sites of the Dnieper reservoirs under influence of a specific hydrological mode of these sites are considered. On an example of the Kanev reservoir is shown, that the number of kinds on a line of a river site is reduced because of sharp within day of fluctuations of speed of current owing to peak mode of operations hydroelectric power station (HEPS) that settles down above. At the same time initiated by such mode of operations of hydroelectric power station of fluctuation of a level of water promote increase species riches phytoplankton of the basic channel at the expense of receipt of seaweed from water objects of the appendage network. Evenness estimated by an index of a species variety (on Shannon), in phytoplankton of the basic channel and water bodies of the appendage network changed over a wide range depending on number of kinds and degree of their domination.

EFFECT OF LIGHT OF DIFFERENT INTENSITY ON CHLOROPHYLL FLUORESCENCE OF ULVA PERTUSA KJELLMAN (CHLOROPHYTA)

The effects of high-intensity optical radiation on chlorophyll fluorescence of marine alga Ulva pertusa Kjellman (Chlorophyta) were investigated. Method of pulse amplitude modulated (PAM) chlorophyll fluorescence was used for studying the photoinhibition of photosynthesis of alga. It was shown that the treatment of the dark-adapted samples with low-intensity (30 mmolxm-2xs-1) white light doesn't provide any significant difference between values of optimal quantum yield Yopt of illuminated samples and those samples which were kept in the darkness. The treatment of the samples with high (1800 mmolxm-2xs-1) intensity of white light provokes the photoinhibition: the value of effective quantum yield Yеff decreases up to 33% during 2 hours in comparison with the samples which were kept in darkness. The damage of the photosynthetic apparatus of alga by high irradiances is reversible – after the end of the photoinhibitory treatment the values of fluorescence parameters reached the initial level during the next 2 hours. The possible mechanisms of quenching of chlorophyll fluorescence are discussed. The fluorescence parameters such as effective and optimal quantum yields, photosynthetic efficiency and capacity makes it possible to estimate the effects of high-intensity irradiation on photosynthetic organisms.

SPECIES COMPOSITION OF PHYTOEPIPHYTON ON POTAMOGETON CRISPUS L. IN THE RIVER SECTION OF KANEV RESERVOIR (UKRAINE)

In May and July 2003 species composition of phytoepiphyton on Potamogeton crispus L. at 7 stations in the main channel and the appendage network of the river section of Kanev reservoir was investigated. 80 species, represented by 85 intraspecific taxa, from three divisions, 8 classes, 22 orders, 32 families and 46 genera were found. It was established, that Bacillariophyta was dominating on the number of species, the second place belonged to Chlorophyta, the third – to Cyanophyta. Nevertheless vegetation of Potamogeton crispus was finishing in June, some specimens, that were kept in July, maintained a rich species composition of phytoepiphyton, resembling species composition in May. In the main channel of the river section of Kanev reservoir taxa of diatom algae occupied all the places among dominating orders, families and genera, but in the a ppendage network the taxa of green algae were on the second or third places. From the received data followed, that taxonomic diversity and the floristic spectra of phytoepiphyton depended on the morphometry and a degree of the flowing of a water body. In the main channel of the river section of Kanev reservoir the epiphytic species rіchness of Potamogeton crispus was great enough, but it was some lower, than in the appendage network. In water bodies of the appendage network (Obolon) the epiphytic species composition was richer than in its branches (Desenka). Coefficients of floristic similarity testified, that distribution of species composition of phytoepiphyton of Potamogeton crispus on the stations of Kanev reservoir had mosaic character.

INHERITANCE OF THE SEX AT THE INTRACLONAL REPRODUCTION OF THE OBLIGATORILY DIOECIOUS SPECIES NITZSCHIA LONGISSIMA (BREB.) RALFS (BACILLARIOPHYTA)

Male clones of the pennate heterothallic diatom Nitzschia longissima (Breb.) Ralfs were studied. Infrequently they are able to intraclonal reproduction. Predicting diplogenotypic mode of sex inheritance we checked the sex of descendants resulting from the intraclonal reproduction. Both male and female viable and fertile clones were revealed in the intraclonal progeny. Male descendants proved to be able to reproduce themselves intraclonally as well. Two new clones derived from the second inbred generation turned to be male ones. The sexual process was isogamous when intraclonal reproduction take place and heterogamous at interclonal reproduction. The gamete form and behavior are heritable attributes associated with the sex. The possibility of change of "monoecious" and "dioecious" generations in the life cycles of diatoms is discussed.

CONTRIBUTION TO STUDY OF CARBOHYDRATES IN TERRESTRIAL ALGAE

As a result of study of the ratio of various groups of carbohydrates in cells of widely distributed terrestrial algae Desmococcus olivaceus (Pers. ex. Ach.) Laundon, Trentepohlia umbrina (Kutz.). Born., Nostoc commune Vauch., Gloeocapsa magma (Breb.) Kutz. it was revealed that the main part of their carbohydrates are concentrated in the groups of reserve and structural polysaccharides. The fraction of low-polymeric carbohydrates was represented scanty. The comparison of obtained data with information concerning carbohydrates of phylogenetically relative species of aquatic forms has shown that in green algae more than the half of carbohydrates belongs to low - polymeric fraction. In cells of aquatic blue-green algae ratio of carbohydrate groups is similar to those of terrestrial algae. It is supposed that revealed composition of carbohydrates in terrestrial algae helps them in survival in unfavorable environmental conditions; it is related to cell protection against desiccation and supports their vital activity during the period of anabiosis. Similar ratio of carbohydrates in the cells of terrestrial and aquatic blue-green algae, in our opinion, is related to their high plasticity and the ability of a great number of species to inhabit various ecotopes, ranging from water bodies to dry rocks.
