[Characteristics of spore-forming bacteria of the genus Bacillus that break down caprolactam].

Five strains of sporeforming bacteria were isolated from sewage of capron industry and their morphological, cultural, as well as physiological and biochemical properties were investigated. Four strains were identified as Bacillus subtilis and one as Bacillus pumilus. The cultures were able to grow in mineral medium with caprolactam as a source of carbon and nitrogen. The influence of growth conditions on the rate of caprolactam decomposition in synthetic medium was studied.

[Influence of clay minerals on the oxidative activity of the caprolactam destructors Bacillus subtilis 6 and 21].

By the Warburg manometric method the respiratory activity of the caprolactam destructors--Bacillus subtilis strains 6 and 21 was measured. The bacteria grown on the synthetic nutrient medium with caprolactam as the sole source of carbon and nitrogen oxidized that substrate more intensively than the cells grown on meat-peptone agar. The activity of caprolactam oxidation by the cultures showed strain differences. Clay minerals--montmorillonit, palygorskit, bentonit and vermiculit--stimulated the glucose and caprolactam oxidation by the above bacteria. The highest stimulating effect was produced by montmorillonit.
