Spatiotemporal variation in litter bacterial community of ayiramthengu mangrove ecosystem of Kerala coast, India

The present study focusses on the spatiotemporal variation of litter bacterial composition isolated from Ayiramthengu mangrove ecosystem of Kerala coast. Monthly sampling was conducted from three different sampling stations of mangrove ecosystem for various physicochemical parameters and bacterial analysis. Total heterotrophic bacteria study revealed that there was significant difference in bacteria among different seasons as well as different stations. 18 genera of gram-negative bacteria and 4 genera of gram-positive bacteria were isolated. Acinetobacter sp. was the dominant bacteria. This indicate that, Ayiramthengu mangrove contains an abundant number of bacteria, which were directly influenced by the different physicochemical parameters in the ecosystem.
