摘要：

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