Tryptose Sulphite Neomycin Agar 500G

Tryptose Sulphite Neomycin Agar is recommended for selective isolation and enumeration of Clostridium perfringens in food or other specimens. Tryptose and yeast extract provide nitrogenous compounds, vitamin B complex and other growth nutrients. Neomycin and polymyxin B sulphate inhibit gram-negative enteric bacilli. Neomycin is lethal for C. bifermentans. The colonies of C.perfringens are black due to the ferric sulphide formed after the sulphite reduction.
