microbial population rate were investigated in the estuarine water, isolated
from the Sundarban Mangrove Forest, India. Our study revealed that
optimum salinity for the growth of bacteria and phytoplankton were totally
differed and phytoplankton showed more resistance to fluctuation in salinity
than that of cultivable bacteria. The bacterial growth rate was found to be
maximum in between 15 to 17 psu of salinity whereas the growth rate of
phyto- plankton was maximum in between 25 to 27 psu of salinity. Both
bacteria and phytoplankton showed positive correlation with dissolved
nutrients, nitrate and phosphate. Phytoplankton population shows significant
response with fluctuation of silicate concentration, but bacteria did not
respond. Both bacteria and phytoplankton showed their higher population
rate between 7.2 to 7.4 pH. Salinity played pivotal role among all selected
physicochemical parameters in the growth pattern of bacteria and phytoplankton
collected from the estuarine water of the Sundarban mangrove
forest.
