A new peptide antibiotic complex B-43, active against Gram-positive and Gram-negative bacteria, was isolated from a strain of Bacillus circulans. This antibiotic contains aspartic acid, valine, isoleucine, leucine, phenylalanine and 2,4-diaminobutyric acid. It seems to be related to polypeptin and antibiotic complex 4205, but differs in that it contains aspartic acid residue.
从环状芽孢杆菌的一个菌株中分离出一种新的肽抗生素复合物B - 43,它对革兰氏阳性菌和革兰氏阴性菌均有活性。这种抗生素含有天冬氨酸、缬氨酸、异亮氨酸、亮氨酸、苯丙氨酸和2,4 - 二氨基丁酸。它似乎与多肽菌素和抗生素复合物4205有关,但不同之处在于它含有天冬氨酸残基。
