Abstract
The invention provides a process for obtaining a second micro-organism by derivation from a first micro-organism, each micro-organism having the capability of producing an extra-cellular product when grown in the presence of a carbon-containing substrate, and the substrate uptake system of the first micro-organism being limiting for the production of the extra-cellular product, which comprises the steps of growing the first micro-organism under glucose limitation, and isolating the second micro-organism in which the glucose uptake system is at least partially derepressed, which process may further comprise the additional steps of growing the isolated second micro-organism and recovering the extra-cellular product; Agrobacterium radiobacter NCIB 40018, and its use for preparing a heteropolysaccharide.
