Axenic cultures of symbiotic cyanobacterial isolates Aphanocapsa sp. (NTK28), Nostoc sp. (NTK29) and Nostoc sp. (NTY30) were subjected to different temperature and light intensity. Among four different temperature set, 20°C showed maximum growth rate in all the three symbiotic cyanobacterial isolates except NTK30 and different light intensity tested no significant growth obtained.
