Hi. I look fof Streptomyces sp ATCC 53453, 53454. These two strains were deposited at ATCC in 1988, in connection with patent 4759928, Antibiotic Treponemycin. The said Treponemycin was later shown to be but a well known Borellidin (discovered in 1948 ) The ATCC 53453, 53454 disappeared from ATCC. Has anyone heard of it?
