Method for stimulating the mating of microorganisms in liquid medium

摘要

The invention relates to a method of stimulating the mating of microorganisms with sexual or parasexual life cycle, preferably yeast (e.g. Saccharomyces cerevisiae) in a liquid medium, which is characterized in that the microorganisms of differing mating type are cultured in the liquid medium in the presence of a high-molecular swellable compound, preferably polyethylene glycol. The invention also relates to a screening method based thereon ("yeast two hybrid" system; Y2H).
