Lactobacillus Streptococcus Differential HiVeg™ Medium is recommended for differentiation of Lactobacilli and Streptococci on the basis of colonial morphology, TTC reduction and casein reaction. The reduction of triphenyl tetrazolium chloride in connection with the casein reaction allows differentiation between lactobacilli and streptococci by means of colony morphology. Addition of 2, 3, 5-Triphenyl-Tetrazolium Chloride (T.T.C.) (FD057) solution makes media selective. Lactobacillus delbrueckii shows red, rhizoidal, surrounded by opaque zone while Streptococcus thermophilus shows red, smooth, surrounded by clear zone colony characteristics on the media. This medium is prepared by replacing animal peptones with vegetable defined peptones to avoid BSE/TSE/GMO risk.
