Abstract
The algal symbiont of Azolla - Anabaena azollae (AS-DS) and free-livin g A.variabilis (SAo) colonized and immobilized well in all the solid m atrices such as hollow fibre, polyurethane foam, cotton and silk cotto n. Biomass production was more under immobilized state than under free -living state. Heterocyst frequency, nitrogen fixing activity and ammo nia excretion were significantly higher under immobilized state than u nder free-living conditions.
