[Special conditions for the cultivation of genetically engineered microorganisms]

Using recombinant strains recently the cultivation of microorganisms for biotechnological purposes has reached a qualitative new level. With respect to the optimization of such cultivation processes appropriate variations of genetical, physiological and biochemical parameters will be necessary. This review summarizes trends of construction of vectors and problems of correlations between hosts and vectors with regard to their application in discontinuous and continuous bioreactor-procedures.
