The overall aim of this study was to grow green algae <em>Cladophora glomerata</em>, extract oil from it, and characterize the extracted oil to gain insight into its physicochemical properties. The effects of parameters affecting the solvent extraction process, temperature, time and biomass particle size were investigated at a fixed solvent ratio of 4:1 hexane to ether. An optimization of oil separation from algae biomass via the solvent extraction method was studied. The obtained results showed that at the extraction temperature of 60 oC, extraction time of 2.5 h, and the particle size of ≤0.6 mm, the maximum oil yield was 18.3% from the process. The functional group analysis revealed the presence of alkane, esters, carboxylic acid, and unsaturated groups on the extracted oil, while the result from the fatty acid profile analysis confirmed the dominance of oleic acid. The physicochemical properties of the extracted algal oil conformed to the ASTM standard.

Four freshwater algae, including Cladophora glomerata, Oedogonium westii, Vaucheria debaryana and Zygnema insigne, were tested for their bioaccumulation capacity for cadmium (Cd), chromium (Cr) and lead (Pb) in a controlled environment with an average temperature of 18 °C, and light/dark duration of 12:12 h. Experiments were performed in aqueous solutions containing selected heavy metals (HM) (ranging from 0.05 to 1.5 mg L−1) with 0.5 g of living algae at 18 °C and pH 6.8. The results indicated that C. glomerata was observed to be the most competent species for the removal of Cr, Cd and Pb from aqueous solutions. HM removal trends were in the order of Cd&gt;Cr&gt;Pb while the removal efficiency of selected algae species was in the order of C. glomerata, O. westii, V. debaryana and Z. insigne. The bioaccumulation capacity of C. glomerata, V. debaryana and Z. insigne was observed for different HM. Removal of HM was higher with low levels of HM in aqueous solutions. The results indicated that C. glomerata, O. westii, V. debaryana and Z. insigne had significant (P ≤0.01) diverse bioaccumulation capacity for Cr, Cd and Pb.

Clostridium Botulinum Type E

In recent years, massive avian die-offs from Clostridium botulinum type E infection have occurred in the Sleeping Bear Dunes National Lakeshore (SLBE) area of Lake Michigan. These outbreaks have been coincidental with massive blooms of the green algae Cladophora , mostly Cladophora glomerata . We tested the hypothesis that Clostridium botulinum type E can grow under suitable conditions in these algal mats. In a lab mesocosm study, Cladophora from four outbreak-impacted beaches from SLBE were compared with four unimpacted beaches in the Milwaukee–Racine area for bontE gene of Clostridium botulinum. Frequency of the bontE gene was higher after incubation (25 °C for up to 6 weeks) of Cladophora from impacted vs. the unimpacted area. Since no type E gene was detected initially in Cladophora from any of the eight locations, we infer that the increased occurrence of type E gene arose from spore germination or vegetative Clostridium growth within the existing algal mats of SLBE. Moreover, we found that the congener Clostridium perfringens readily grows in mesocosms containing Cladophora.

The publication presents the results of a floristic study of green algae of some salt lakes in the Republic of Khakassia: Shira, Tus, Ulugkol, Altaiskoe, conducted in the period from 2006 to 2019. The lakes are located in the steppe zone within the Chebakovo-Balakhtinsky and Minusinsky basins of the Nazarov-Minusinsky intermountain depression. The mineralization of water in the lakes for the study period was: 15,9–21,9 g/l (Lake Shira); 52,7–115,07 g/l (Lake Tus); 18,3–21,7 g/l (Lake Ulugkol); 42,7 g/l (Lake Altaiskoe). The values of pH of the water lakes are alkaline – 8,2–9,8. In plankton, benthos and periphyton of 4 lakes we found 30 species of green algae belonging to 5 classes, 10 orders, 17 families, 22 genera. Cladophora glomerata and Oocystis submarina species were discovered in all the lakes surveyed. In different algae communities, along with cyanoprokaryotes and diatoms from green algae, the following species dominated: Botryococcus braunii, Chlorella chlorelloides, Cladophora glomerata, Cladophora sp., Dunaliella salina, Hindakia tetrachotoma, Oocystis submarina, Rhizoclonium hieroglyphicum, R. riparium, Spermatozopsis exsultans, Sphaerocystis planctonica. Among them, highly active species with a relative frequency of occurrence of 74–50 % were: Dunaliella salina (in lakes Ulugkol and Altaiskoe), Sphaerocystis planctonica and Oocystis submarina (in lake Ulugkol). Rare species for the flora of the region are noted: Picocystis salinarum – in lake Altaiskoe, Percursaria percursa – in the lake Tus. In relation to water mineralization, the green algae of the studied lakes belonged to the groups of indifferents, halophiles, and polygalobes.
