Description 382-385
Facultative alkalophilic bacteria Planococcus sp. (EMGA-26), Bacillus sp. (EMGA-29) and Corynebacterium spp. (EMGA-33 and 130) were isolated from mangrove soil samples. Neutrophiles were predominant than alkalophiles. Buffering capacity and membrane H+ conductance were investigated for the strains grown in PPYG medium at pH 10.5 using acid pulse technique. Bacillus sp. showed higher buffering capacity than Planococcus sp. and Corynebacterium
spp. Buffering capacity was two-fold higher in Corynebacterium sp. EMGA-33 than in EMGA-130. The membrane
H+ conductance was high in Bacillus sp. and was directly proportional to the buffering capacity values. The
Bacillus sp. (EMGA-29) had higher cell membrane adaptability in high pH environment than the Planococcus sp. and
Corynebacterium spp.
