M17 AGAR BASE (VEG.)

M17 Veg Agar Base is specially developed by using Veg peptone and Veg extract to avoid BSE/TSE risks associated with animal origin peptone. M17 Veg Agar Base is the modification of M17 Agar Base which is based on the formulation described by Terzaghi and Sandine for the cultivation and enumeration of lactic Streptococci and their bacteriophages.
It is possible to study plaque morphology and lysogeny using this medium. Lactic Streptococci are nutritionally fastidious and require complex media for optimal growth. Disodium glycerophosphate maintains the pH above 5.7 as acid is produced by lactose fermentation. The maintenance of pH is very important as lower pH results in injury and reduced recovery of lactic Streptococci. Glycerophosphate does not form precipitate with calcium which is needed for the plaque assay of lactic bacteriophages.
M17 Veg Agar is suitable for cultivation and maintenance of starter cultures for cheese and yoghurt manufacturing. This medium helps in detecting Streptococcus mutants which is a lactose non-fermenter.
