The effect of indigo dye effluent on the freshwater microalga Scenedesmus quadricauda ABU12 was investigated under controlled laboratory conditions. The microalga was exposed to different concentrations of the effluent obtained by diluting the dye effluent from 100 to 175 times in bold basal medium (BBM). The growth rate of the microalga decreased as indigo dye effluent concentration increased ...

Critical algal blooms in lakes increased the concentration of algal organic matter (AOM), significantly altering the drinking water treatment requirements, including coagulation, oxidation and disinfection. This study utilized Microcystis aeruginosa (cyanobacteria), Scenedesmus quadricauda (Chlorella) and Nitzschia palea (diatom) as models to investigate the AOM's primary characteristics and th...

A pot experiment was conducted to study the influence of various irrigation regimes on some metabolic pools of wheat and alfalfa plants. The photosynthetic pigments and soluble proteins of the tested plants significantly increased when irrigated with sewage amended with Scenedesmus quadricauda or Nostoc sp. On the other hand, soluble carbohydrates decreased in wheat shoots at different treatmen...

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.

This work compared the sensitivity of three cyanobacteria (Anabaena flos-aquae, Microcystis flosaquae and Mirocystis aeruginosa) as well as five green algae (Pseudokirchneriella subcapitata, Scenedesmus quadricauda, Scenedesmus obliquus, Chlorella vulgaris and Chlorella pyrenoidosa) to four pesticides through 96h short-term chronic tests. The results showed that the toxicity of the pesticides t...
