Emergence of dissociants in colonies of Rhodococcus erythropolis -producer of carotenoids

摘要

The frequency of dissociative transitions of the studied strain has been determined. It is discovered that at prolonged cultivation the quantity of emerged dissociants in colonies increases. If a colony is in such conditions of growth, when the emerged variants have selective advantages over the initial variant, then dissociation ability will be found quickly and yield of the target product may change.
