Abstract
- Abstract: The isolated cyanobacterium containing biopigments like chlorophyll-a, phycoerythrin, phycocyanin, and carotenoid was cultured under different quality of light modes to ascertain biomass and pigment productivity. On the basis of 16S rRNA gene sequence, the isolate was identified as Pseudanabaena sp. Maximum biomass concentration obtained in white-, blue-, and green-light was 0.82, 0.94, and 0.89g/L, respectively. It was observed that maximum phycoerythrin production was in green light (39.2mg/L), ensued by blue light (32.2mg/L), while phycocyanin production was maximum in red light (10.9mg/L). In yellow light, pigment production as well as the growth rate gradually declined after 12days. Carotenoid production decreased in blue-, white-, and red-light after 15days, while in green light it had increased gradually. The present communication suggests that Pseudanabaena sp. can be used for commercial production of phycoerythrin when grown under green light. [Copyright &y& Elsevier]
