چکیده
Volatile substances of the green microalga Scenedesmus incrassatulus, cultivated in fresh and salt water, were studied. Cultivation in fresh water diversifies volatile secondary metabolites. Hydrocarbons and derivatives of the acetate pathway predominate when algae are grown in salt water; isoprenoids and aromatics are more abundant after fresh water cultivation.

Assessment of Cadmium, Nickel and Lead Toxicity by Using Green Algae Scenedesmus Incrassatulus and Human Cell Lines: Potential In Vitro Test-Systems for Monitoring of Heavy Metal Pollution
Background: Pollution of aquatic ecosystems with heavy metals leads to decrease of the biodiversity and accumulation of toxicants in the food chain. Species of the genus Scenedesmus are sensitive indicators of environmental changes and have been used for the evaluation of risk factors for contamination of aquatic ecosystems. The microalga Scenedesmus incrassatulus can remove chromium and cadmiu...

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 ...

Recently, biological methods are used for remediation of various pollutants especially heavy metals. Algae are organisms which can accumulate and transform these pollutants with different mechanisms. In this regard immobilization of these microorganisms is a technique that is used for different purpose. So after primary screening of microalgae (Spirulina, Tetraselmis, Chlorella, Scenedesmus, Mi...

The cells of the green unicellular alga Scenedesmus incrassatulus Böhl, strain R-83 released organic chelators for Fe(III) in inorganic nutrient medium both in iron-deficient and in iron-replete conditions. Iron-deficient cells released chelators capable to bind 11nmol Fe. mg (cell DW)–1.h–1, while the chelators released from iron-sufficient cells after contact with Fe(III) were sufficient to b...
