Microalgae reckon one of the most promising organisms due to their numerous applications in biotechnology, such as, biomass utilization extract various primary and secondary metabolites. These compounds benefit food pharmaceutical industries energy field, biofuel hydrogen gas production. Therefore, it is necessary find sustainable ways actively preserve isolates productive strains with purity f...

The selenium-enriched Scenedesmus biomass of patented selenium-resistant strain SeIV was tested in a broiler chicken diet in comparison with sodium selenite supplementation. Feed conversion, mortality and live weight were not significantly influenced by the source of selenium. Supplementation of either form of selenium significantly increased the Se concentration in breast muscle with a more pr...

Various kinds of temperature rules have been proposed for biological use, but reasons for choosing one before another have seldom been given. Arguments for such choices should include both theoretical and mathematical-statistical aspects. In this paper the relationships of algal growth constants, such as ~t (maximum specific growth rate), q0 (minimum nutrient content of the algae), Y (yield coe...
