Bambermycin (Flavomycin) is a complex of antibiotics obtained from Streptomyces bambergiensis used as a food additive for poultry and swine.[1] The complex consists mainly of moenomycins A and C.[2]

Flavomycin is effective against Gram-positive bacteria, but it does not have significant action against Lactobacillus, Bifidobacterium, and other protective bacteria.[3] Its mechanism of action involves inhibition of bacterial wall synthesis.[3]

Synonyms included flavofosfolipol, gainpro, menomycin, and flavophospholipol.[2]
