摘要
Physiological characteristics of a novel strain of the halophilic alga Dunaliella salina IPPAS D-232 isolated from the hypersaline lake Razval (Sol-Iletsk, Orenburg region) were studied. It was shown that the extract from the cells of this strain manifested antioxidant properties and also antibacterial activity relative to opportunistic bacteria. The influence of medium stirring and salinity on the level of D. salina antioxidant activity was assessed: it was established that medium salinization (93 g/L) and continuous stirring favored the highest accumulation of D. salina IPPAS D-232 biomass. It was found that the extremely halophilic archaea Halorubrum tebenquichense and moderately halophilic bacterium Marinococcus halophilus stimulated D. salina development and increased its antioxidant activity. The results obtained expand our knowledge of specific ecological features of the studied microalgal species; they could form the basis for the development of new approaches to the mass cultivation of D. salina.
