Abstract
Morphometric and physiologic-biochemical characteristics as well as the productivity of the green terrestrial microalga Bracteacoccus minor were investigated in a two-stage batch culture. The specific adaptive responses, which the microalga developed under the experimentally induced secondary carotenogenesis were: high cellular resistance to sodium acetate, the accumulation of a multicomponent mixture of secondary ketocarotenoids with the dominance of astaxanthin diesters (37−42% of the total carotenoids) and a large lipid content in algal biomass (53−63% of dry matter).
