摘要：

Contamination of aquatic ecosystem including paddy fields by pesticide is a serious environmental global issue. Pesticides affect non-target microorganisms including cyanobacteria. Thus it is necessary to select tolerant strains which can be used as biofertilizer. The present communication deals with herbicide anilofos induced physiological and biochemical parameters related to photosynthetic pigments and defense system in a paddy field cyanobacterium Oscillatoria simplicissima in in vitro conditions. Reduction in growth, photosynthetic pigments and ascorbate content of test organism accompanied with increase in stress enzymes such as superoxide dismutase (SOD), catalase. (CAT), peroxidase (POD) and proline content was observed in selected herbicide doses. Decrease of photosynthetic pigments and increase of SOD, CAT, POD and proline is an indication of their involvement in free radical scavenging mechanism.
