Abstract
Occurrence and distribution of Lactic acid bacteria (LAB) in fresh and frozen
fishes of internal trade, fresh marine fishes as well as brackish and aquaculture farm
fishes were studied vis-a-vis total bacterial counts and total coliforms. Selected LAB
strains wee studied for assessing biochemical and growth characteristics. It was
found that the LAB counts were always 1-2 log cycles less than the total plate counts
in the case of fishes from internal trade. While the LAB were present in fresh and
brackish water fishes, these were not detected in Ocean fresh fish. About 90% of
the LAB strains isolated were characterised as Lactobacillus of which 41% were
streptobacteria and 14% thermobacteria. Nearly 80% of the LAB cultures tested for
antibacterial properties against E. coli, Staphylococcus aureus and Bacillus cereus, none
could inhibit the growth of E. coli and S. aureus. But 13 out of 15 cultures inhibited
the growth of Bacillus cereus.
