| Abstract | ||
| Different 44 bacterial isolates were isolated from biofilms of raw cow milk. The results were elicited that the Gram-negative isolates showed maximum percentage(81.8%) of total bacteria, whereas the minimum(18.2%) was found in the Gram-positive isolates. However, the average number of total bacteria count in biofilms of milk containers was 60000 cell/ ml/ cm. When the mechanism of biofilm formation was followed, using submerged slides technique, it was found that differences in the percentage of Gram-negative isolates (75.3%) from Gram-positive isolates (24.7%), however, the motile bacteria showed more competence than non motile in formation process. These findings suggest that the Gram-negative bacteria, with respect to motile bacteria have significant role in formation of biofilms and spoilage of milk. | ||
