dc.description.abstractMangroves provide a unique ecological environment for diverse microbial communities. They are particularly important in controlling the chemical environment of the ecosystem. Sundarban, being a rapidly changing ecosystem, is under stress due to various anthropogenic activities. The present study was taken with an objective to assess the microbial (fungal and bacterial) diversity with respect to behaviour of nutrients. Three sampling location viz. Canning, Jharkhali and Pakhiralay, were chosen based on anthropogenic stress. It was observed that at Canning, nitrate (7.46 mg.L⁻¹) and phosphate (8.12 mg. L⁻¹) in water were maximum of all the three locations. Total bacterial load (29.83 × 10⁶), Phosphorus solubilising (14.08 × 10⁴ CFU.g⁻¹), N₂ fixing (13.67 × 10⁴ CFU.g⁻¹) and nitrifying bacteria (13.67 × 10⁴ CFU.g⁻¹) as well as exchangeable phosphorus (42 µg.g⁻¹) was highest in the sediments collected at Canning. Sediments associated with dense mangroves (Pakhiralay) showed highest count of cellulose degrading bacteria (45.15 × 10⁴ CFU.g-1). Fungal diversity was also assessed and it was observed that Aspergillus and Penicillium were the most abundant species in the three sampling locations. The study had elucidated the existing environmental conditions played a significant role in the determination of microbial diversity as well as nutrient behaviour in the sediments.en_US
