Abstract:

The present study was designed to test the antimicrobial activity of A1 and A2 milk derived casein hydrolysate on Listeria monocytogenes ATCC19115, Staphylococcus aureus ATCC25924, Salmonella typhi MTCC3917 and Pseudomonas aeruginosa MTCC1688. Milk was collected from cattle belonging to A1A1 and A2A2 genotyped from Cattle and Buffalo Farm, ICAR-IVRI, Izatnagar. The cows used for the study belonged to definite genotype as designated by AGB Division, ICAR-IVRI, Izatnagar. Results showed no antimicrobial activity for A1 and A2 casein hydrolysate; instead it was acting as a bacterial growth promoter. No significant difference (p>0.05) was observed between A1 and A2 casein hydrolysates in bacterial growth of Staphylococcus aureus ATCC25924, Salmonella typhi MTCC3917 and Pseudomonas aeruginosa MTCC1688 at 0 h, 2 h, 4 h and 6 h of hydrolysis except in case of Listeria monocytogenes ATCC19115 at 4 h only. No antimicrobial activity was observed for casein hydrolysate instead it was acting as a bacterial growth promoter, which can be used as supplement in growth media.
