Abstract

Karati, bordia and lashim are dried fish products of Assam. A total of 30 samples of karati (12), bordia (10) and lashim (8) were collected from Guawahati markets and analysed for aerobic mesophilic bacteria, lactic acid bacteria, aerobic
mesophilic spore-formers, yeasts and filamentous moulds. Population of lactic acid bacteria (LAB) ranged from 4- 6.2 log cfu/g, spore-former raged from 1.4-3.8 log cfu/g, yeasts ranged from 1.8-3.3 log cfu/g, and aerobic mesophilic counts
ranged from 4.2-6.3 log cfu/g, respectively in fish products. Mould was not recovered in any sample. Microorganisms isolated and identified from karati, bordia and lashim were Lactococcus lactis subsp. cremoris, Leuconostoc mesenteroides, Lactobacillus plantarum, Bacillus subtilis, Bacillus pumilus and
yeasts Candida. Selected isolates were tested for proteolytic and amylolytic activities. Some of them showed high degree of hydrophobicity. None of the strains produced biogenic amines in the method applied.
