Actaplanin antibiotics (A4696) designated as C2a, D1, D2, K, L, M, N, and O are obtained by the partial acidic hydrolysis of known actaplanins at about pH 1.85 for 2.5 hours at about 90 DEG C. The new actaplanins, like the known actaplanins, are glycopeptides which possess antibacterial activity and, either alone or as a mixture with other actaplanins, improve the feed efficiency in ruminants, swine and poultry. |
