Description 405-411
Population of aerobic and anaerobic bacteria
along the different tidal zones of Sundarban Mangrove forest sediment was studied
to determine their distribution with the availability of different nutrients
and other physicochemical parameters. Lower littoral zone (LLZ) along the shore
which remains inundated by sea water showed more population of anaerobic
bacteria (212 x 104 CFUg-1) than that of mid littoral
zone(MLZ) (102 x 104 CFUg-1) and upper littoral zone(ULZ)

(60 x 104 CFUg-1). Population of aerobic bacteria was
found to be maximum in ULZ (57 x 104 CFUg-1) compared to
MLZ (46 x 104 CFUg-1) and LLZ (14 x 104 CFUg-1).
Population of methanogens increased with rise of sea level which in turn
emitted more methane than CO2. A stable dynamic equilibrium for
growth rate of aerobic and anaerobic bacteria observed in ULZ and is
ecologically more consistent than LLZ particularly with respect to methane
emission from sediment. Anaerobic bacteria are relatively more tolerant to
variable salinity, pH and other physicochemical factors than the aerobic
bacteria.
