The aim of this work is to optimize the growth parameters of D. salina by altering nutritional factors, in order to maximize production of antioxidants and lipid fraction by the microalgae strain. For this purpose, the concentrations of different salts in the growth medium were varied. The biomass obtained was analyzed quantitatively and qualitatively in order to determine biomass concentration and bioactive compounds concentrations in respect to the growth medium composition. Pigments were extracted from the drie...

The effectiveness of rhizobia-legume symbiotic interaction is under the genetic control of macro- and microsymbionts. Both symbionts exhibit high level of genome/genome specificity interaction which is reflected by symbiotrophic indices vary significantly. Virulence and plant dry mass increasing are indices widely used in order to reveal well matched rhizobia strain and variety of legume host plant for practice demand. The aim of the research was to study how allelic polymorphism of symbiotically significant genes...
