Abstract
We describe the use of chemically defined media for the fermentative production of valuable compounds on an industrial scale. Microbial strains which are suitable for fermentation on an industrial scale using a chemically defined medium include fungal, yeast and bacterial strains. Suitable strains can be obtained as wild type strains or by screening and selection after mutagenic treatment or DNA transformation.

15. A method for preparing and/or improving a microbial strain producing a valuable compound of interest which is capable of being fermented in a chemically defined medium, comprising:
-
(a) subjecting a parent strain to a mutagenic treatment and/or to DNA transformation to obtain mutants and/or transformants;
(b) screening the mutants and/or transformants for their growth performance on a chemically defined medium and their production level of said valuable compound of interest; and
(c) selecting mutants and/or transformants which have a good growth performance on the chemically defined medium and/or an improved production level of said valuable compound of interest as compared to the parent strain. - View Dependent Claims (16, 17)
