In such investigation highest TVBC (1.4×106) and (1.2×106) was observed in mango juice and Alo vera juice which is from Khilkhet (street) and and Sadarghat (street) and the lowest TVBC (9.0×105) was observed in malta juice which is collected from banana (1.2×106) and TVBC (9.0×105) was observed in Papaya from Banani. In conclusion, 10 types of selected isolate were selected depending on their growth, colony color and morphology for fi nal study. Enterobacter aerogenes was present in mango juice sample, Pseudomonas aeroginosa was present in apple juice sample, Salmonella Typhimurium was present in malta juice sample, Bacillus cereus was present in orange juice sample and Klebshilla pneumoniae was present in lacchi sample.
