Abstract

Raw garlic extract was stored for 48 h at 26-30 degree C, and its effect on Streptococcus faecalis and Escherichia coli cultures was noted at regular intervals. The antimicrobial activities of garlic extract were stable beyond 48 h when stored at 37 degree C and were stable for 36 h at 58 degree C. Antifungal activity against Aspergillus flavus and Penicillium citrinum was noted up to 8 h at these storage temp. Components of the broth used for testing the activity showed an antagonistic effect against enzyme activity and against allicin as such. Cooked garlic extract stored for up to 24 h at 26-30 degree C showed a significant growth-stimulating activity of bacterial and fungal cultures; the stimulatory activity was due not to alliin, cooked alliin, carbohydrates or organic N, but to a dialysable ninhydrin-positive compound.
