Based on the morphological and cultural characteristics and the results of sequencing the ITS region of DNA, strain SR-1.3 was identified as <i>Penicillium chrysogenum</i>. The SR-1.3 strain exhibits algicidal activity against cyanobacteria and green algae. A dose-dependent and species-specific nature of the algicidal action of the <i>P. chrysogenum</i> SR-1.3 strain has been established. Cyanobacteria show the highest sensitivity to strain SR-1.3. The complete lysis (100%) of cyanobacteria cells is observed when 10% (vol) of the culture liquid or the micromycete filtrate are added to the medium. The algicidal effect of strain SR-1.3 on green algae is 30–70%, depending on the culture. According to the level of sensitivity to the algicidal effect of SR-1.3, the test cultures can be arranged in the series <i>Planktothrix agardhii</i> &gt; <i>Microcystis aeruginosa</i> &gt; <i>Aphanizomenon flos-aquae</i> = <i>Anabaena cylindrica</i> &gt; <i>Scenedesmus quadricauda</i> &gt; <i>Oocystis parva</i>. The inhibitory effect of the strain SR-1.3 mycelium on cyanobacteria and green algae growth does not exceed 3–6%. Based on the results, a conclusion was made about the indirect mechanism of the algicidal action of <i>P. chrysogenum</i> SR-1.3 by excretion into the medium of metabolites that inhibit and/or lyse cells of cyanobacteria and green algae. When toxigenic strains <i>M. aeruginosa</i> and <i>P. agardhii</i> are cultivated on a medium containing exometabolites of strain SR-1.3, the concentrations of microcystins in the medium decreases 3.3 and 1.8 times, respectively, compared with control variants. The ability of <i>P. chrysogenum</i> SR-1.3 to remove the highly toxic MC-LR from the cultivation medium is revealed. The MC-LR content is found to decrease from 1.2 to 0.79 μg/mL over 48 h during the cultivation of strain SR-1.3 on a medium with microcystin.</p>","PeriodicalId":50359,"journal":{"name":"Inland Water Biology","volume":"36 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141610116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patterns of the spatial distribution of species across biotopes and gradients of environmental variables are traced. Twenty-six species of mollusks of this family are identified, with European–Siberian species predominating. Most species of mollusks of the family Sphaeriidae found by us have wide ecological ranges and are found in water bodies of various types. It is found that the contribution of Sphaeriidae to the species richness and functioning of aquatic communities in rivers in the conditions of branched lake–river systems (Lake Onega basin) exceeds the values usual for rivers with a small number of lakes in the catchment area. Using the ANOSIM and PERMANOVA methods, it is proven that the species composition of rocky rapids and riffles, sandy rifts, and soft bottom soils is different. Using the IndVal test, seven species are shown to have a statistically significant association with one of these biotopes, and four of them have a statistically significant association with the rocky bottoms of river rapids and riffles. Using the NMDS method, it is shown that the greatest changes in the species composition of representatives of Sphaeriidae are observed when environmental conditions change from small streams with a slow current and brown water to large rivers with a fast current and clear water.</p>","PeriodicalId":50359,"journal":{"name":"Inland Water Biology","volume":"46 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141610114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
