The microbial population and nutrients status of the surface water indicates the nutrient dynamics in the study area. Nutrients in surface water directly provide the available source of nutrients to the microbes. Nutrients in the water such as NO (2.77-46.08mg/L), PO4 3-(0.32-2.81 mg/L), SO2-(1892-3839.98 mg/L) and dissolved silica (SiO) (3.32-16.98 mg/L) has been reported. Population of nitrate forming bacteria with higher population count at Old Bedi Port (M2), Narara (M5) and Mundra (M8) was reported while Phosphate solubilizing bacteria with higher count at Mundra (M8) and Jodiya (M10). The cellulose degrading bacteria was reported exceptionally high at Mundra, Narara and Old Bedi Port. The higher population count in the microbes synchronized with the nutrients availability in the surface water. Lack of significant correlations among the nutrients indicate the influx of anthropogenic inputs and waste discharges containing nutrients from river runoff into these environments.
