title: Studies on aculeacin. II. Isolation and characterization of aculeacins B, C, D, E, F and G.
abstract: Six new antibiotics were isolated as the minor components related to aculeacin A from the culture broth of Aspergillus aculeatus M-4214 and named as aculeacins B, C, D, E, F and G. Their physico-chemical properties were analogous to those of aculeacin A and they showed significant activity against fungi. All of the minor components liberated palmitic acid on alkaline hydrolysis. Amino acid analysis showed that threonine and hydroxyproline are common constituents of aculeacins.
