Harmful algal blooms (HABs) are overgrowths of toxic strains algae (diatoms, green) and cyanobacteria (blue-green algae). While occurring naturally, human-induced environmental changes have resulted in more frequent occurrences such worldwide. Meantime, the ecotoxicological risk HABs is rarely evaluated by means standard test methods. For first time, genotoxic potential HAB event 2020 was asses...

Cyanobacteria are aquatic and photosynthetic they survive in fresh water ponds sewage water. Since these cyanobacteria quite small unicellular, often grow large colonies more enough to see by naked eye. produce bluish green colour pigments as phycocyanin, phycobiliproteins carotenoids. It may surprise you know that still around one of the largest most important groups bacteria on earth. The cya...

Microcosm experiments with natural indigenous phytoplankton communities were conducted to assess the effects of waters from oil sands extraction processes, emphasizing the naphthenate and salt constituents. Process waters of varying ages (zero to eight years) remediation histories, and chemical composition were obtained from outdoor mesocosms and inoculated with phytoplankton assemblages from a...

This paper reports experimental measurements of the radiation characteristics of green algae used for carbon dioxide fixation via photosynthesis. The generated biomass can be used to produce not only biofuels but also feed for animal and food supplements for human consumptions. Particular attention was paid to three widely used species namely Botryococcus braunii, Chlorella sp., and Chlorococcu...

BACKGROUND Recent understanding that specific algae have high hydrocarbon production potential has attracted considerable attention. Botryococcus braunii is a microalga with an extracellular hydrocarbon matrix, which makes it an appropriate green energy source. RESULTS This study focuses on extracting oil from the microalgae matrix rather than the cells, eliminating the need for an excessive ...
