Abstract
Salt tolerance of selected cultures of Pseudonionas, Moraxella, Vibrio, Micrococcus,
Acinetobacter, and Flavobacteria/Cvtophaga were determined. More than 80% of the cultures belonging to each of the above genera, were capable of growth in presence of
1 .5 to 3.5% salt (NaCI) and at least 25 to 30% of the cultures in each group required
1 .5 to 3.5% salt for growth . Forty per cent each of Pseudomonas and Vibrio strains and
30% each of Moraxella, Micrococcus and Flavobacteria/Cytophaga strains tolerated 10% salt . Majority of the cultures belonging to the genet a Pseudomonas, Vibrio, Moraxella, Micrococcus, Acinetobacter and Flavobacteria/Cvtophaga were slightly halophilic (2 to 5% salt tolerant), about 25% especially of Micrococcus spp ; moderately halophilic (5 to 20% salt tolerant) and none from Pseudomonas, Vibrio, Moraxella, Acinetobacter and Flavobacteria/Cytophaga spp . extremely halophilic (20 to 32% salt tolerant) .
