Cyanobacteria, Anabaena oryzae, Endosulfan and Insecticide.

A study on the heterocysts nitrogen fixing Cyanobacterium, Anabaena oryzae was carried out to investigate the effect of an organo chlorine insecticide hexachloro-hexahydro-methano-benzodioxatheipine-oxide, (called as Endosulfan) at different concentration of 4,8 and 12 µg ml-1 on the photosynthetic pigments Chl-a, Carotenoids and phycobiliproteins-phycocyanin, allophycocyanin and phycoerythrin. The insecticide Endosulfan showed to be deleteriously affecting the activities in the cyanobacterium. As early as the 4th day, Chl-a and carotenoids reduced by 38% and 20% respectively. The phycobilioproteins declined by 60%, 64%, and 28% with respect to phycocyanin, Allophycocyanin and phycoerythrin. Moreover, endosulfan adversely depleted the cellular activities, leading to a marked decrease in the carbohydrates, proteins and phenols. Despite of deleterious effect of Endosulfan on the Cyanobacterium, Anabaena oryzae. A unique regenerating ability in presence of the insecticide was observed by the end of 12 days in the lower doses of insecticides.
