BUTI MEDIUM New 500 grams/bottle

BUTI Medium is an indicated medium used for the MPN of Clostridium tyrobutiricum. Clostridium tyrobutyricum is a rod-shape, Gram-positive bacteria. The spores present in the raw milk, ferments lactic acid in high pH cheeses resulting in the formation of butyric and acetic acid and hydrogen gas under anaerobic conditions. In all cheeses with eyes, undesirable gas formation can occur if large numbers of C. tyrobutyricum are active. Their growth usually occurs months after cheese is made and after much proteolysis has occurred. The result is split eyes or newly formed large slits called cracks. Metabolism by C. tyrobutyricum also results in rancidity and H2S formation. Tryptic hydrolized of casein and beef extract provide nitrogen, vitamins, minerals and amino acids essential for growth. Yeast extract is source of vitamins, particularly the B-group. Sodium Acetate acts as a buffer. Sodium chloride supplies essential electrolytes for transport and osmotic balance. Starch in the medium acts as a growth factor, functioning like a colloid protector and neutralizes toxic products that form during the development of the organisms.
