SCREENING OF GREEN MICROALGAE AS A POTENTIAL SOURCE OF NATURAL KETOCAROTENOIDS 2. FEATURES OF GROWTH AND SECONDARY CAROTENOGENESIS IN THE REPRESENTATIVES OF THE GENUS BACTEACOCCUS (CLOROPHYСEAE)
Keywords:
Bracteacoccus spp., cultivation, astaxanthin, canthaxanthinAbstract
Productivity characteristics of two Bracteacoccus species (B. minor и B. giganteus) under screening of commercially suitable natural ketocarotenoid producers by uniform mode of two stage batch cultures have been determined for the first time. It has been shown that in accordance with to specific growth rate (0.50 – 0.59 day-1), total carotenoid yield (≈ 1.7 mg·l-1·day-1) and carotenoidcontent in dry biomass (0.9 – 1.0 %) both species can be recommended for further studies on developing of their mass culture technology.
