Producing a modified L-form bacterial strain by culturing the strain in complex medium and subjecting it to temperature stress, provides bacteria useful to produce recombinant proteins

Producing a modified L-form bacterial strain, comprising culturing a bacterial strain adapted to a complex culture medium at alternate temperatures between 20 and 40 deg C, and fermenting the strain when hydromechanical stress of the cells increases, is new. Independent claims are also included for...

description Producing a modified L-form bacterial strain, comprising culturing a bacterial strain adapted to a complex culture medium at alternate temperatures between 20 and 40 deg C, and fermenting the strain when hydromechanical stress of the cells increases, is new. Independent claims are also included for the following: (1) an L-form bacterial strain produced by the novel method; and (2) producing a gene product, comprising: (a) culturing the novel transformed bacterial strain transformed with a nucleic acid sequence encoding the product; and (b) expressing and isolating the gene product. Verfahren zur Gewinnung von modifizierten L-Form-Bakterienstämmen bei dem man (a) einen an ein komplexes Nährmedium adaptierten L-Form-Bakterienstamm alternierend bei unterschiedlichen Temperaturen im Temperaturbereich von 20 bis 40 DEG C kultiviert und (b) bei ansteigender hydromechanischer Belastung der Zellen fermentiert, modifizierte L-Form-Bakterienstämme, die gemäß dem Verfahren erhältlich sind, und deren Verwendung zur Herstellung von Genprodukten.
