The present study was undertaken to investigate the possibilities of some plant growth regulators – abscisic acid, fluridone, methyl jasmonate, salicylic acid and the cytokinin 4-PU-30 to participate in the disease tolerance induction in the unicellular green alga Scenedesmus incrassatulus invaded with the unicellular fungal parasite Phlyctidium scenedesmi. We established that protein profiles ...

Hydrogen is a highly promising energy source with important social and economic implications. The ability of green algae to produce photosynthetic hydrogen under anaerobic conditions has been known for years. However, until today the yield of production has been very low, limiting an industrial scale use. In the present paper, 73 years after the first report on H(2)-production from green algae,...

Laboratory studies were conducted to determine the effects of different concentrations of Cu, Cd, Zn and mixture (equal concentrations from the three heavy metals) on growth and some oxidative stress (catalase and glutathione reductase) on Scenedesmus obliquus (microalgae) after exposure for 24, 48, and 96 h. In addition, the uptake of Cu, Cd and Zn were determined in the culture medium after 2...

In this study, we investigated the bioaccumulation of copper (Cu) by microgreen algae Scenedesmus acutus and Chlorella vulgaris and toxicity of dietborne copper from algae to benthic ostracod Heterocypris incongruens. Scenedesmus acutus and C. vulgaris were exposed to different concentrations of waterborne Cu for 10 days then the ostracod was fed this food exclusively under 24h dark condition f...

Scenedesmus obliquus, Chlorella vulgaris, Chlorella kessleri and a natural Bloom were cultivated in batch experiments, under controlled conditions, in urban wastewater (WW) and synthetic wastewater (SW) under 5% CO2 in air, with the object of estimating their capacity for nutrient removal, carbon dioxide biofixation, and generation of valuable biomass. In both culture media, the Bloom (Bl) and ...

Two Iranian strains of Brachionus rotifers were cultured under different food and salinity regimes. The rotifers were fed with five algal types (freshwater and marine Chlorella vulgaris, Nannochloropsis occulata, Isochrysis galbana and Scenedesmus obliquus) at three different salinities (5, 15 and 25 g/L) and their reproductive and growth parameters were assessed. The maximum number of ovigerou...

In laboratory conditions, the analysis of total toxicity some technogenically disturbed soils Belgorod region was carried out using bioassays: Daphnia magna Straus , green algae Scenedesmus quadricauda (Tiger) and Lepidium sativum L. As a result experiments, degree tested established. The conducted studies confirm high information content when three bioassays for soil toxicity.
