[Taxonomic position of cultures of the family Micromonosporaceae].

The paper describes cultures that can be assigned to the genus Micropolyspora according to such properties as the presence of aerial mycelium, catenae of spores and galactose in the composition of sugars in the cell wall. However, the cultures contain xylose in the cell wall and therefore are related to the genus Micromonospora. These findings as well as the atypical proportion between DAPA and its isomers suggest that the cultures occupy an intermediate position between the genus Micromonospora and the genus Micropolyspora.
