The axenic culture of Aphanocapsa biformis was obtained in the laboratory .For the biomass production, different culture media were used namely BG-11, Fogg’s medium, Allen and Arnon medium, Zarrouk’s medium and CFTRI medium The biomass was harvested by filtration through double layered muslin cloth and dried using air blower.After harvesting, the biomass obtained was subjected to the growth analysis.Carotenoids were estimated by spectrophotometer method according to Gowenlock [2].Out of the different culture media used, BG-11 medium supported the growth of Aphanocapsa biformis species properly as compared to other media used. The carotenoids content was more in Aphanocapsa biformis grown in Fogg’s medium followed by the BG-11 medium.
