    Abstract: The subject disclosure discloses a chemical intermediate in antibiotic synthesis of the structure: ##STR1## wherein R.sub.1 is H or OH and the asterisks indicate asymmetric carbon atoms. Compounds of this type may be obtained by fermentation with a strain of B. subtilis under aerobic conditions. Compounds of the above structure are biologically inactive but are converted by phosphorylation of the hydroxyl group to produce compounds of the structure: ##STR2## wherein R.sub.1 is H or OH, which are useful antibacterial substances having a broad spectrum of antibacterial activity.

    Abstract translation: 本发明公开了一种结构抗生素合成中的化学中间体:其中R 1是H或OH并且星号表示不对称碳原子。 这种类型的化合物可以通过在需氧条件下用枯草芽孢杆菌菌株发酵来获得。 上述结构的化合物是生物学上无活性的,但是通过羟基的磷酸化转化而产生下列结构的化合物:其中R1是H或OH,它们是具有广谱抗菌活性的有用的抗菌物质。
