Analysis of factors responsible for the regeneration to intact cells from sphaeroplasts of Saccharomyces cerevisiae

The regeneration of Saccharomyces cerevisiae, NCIM 3288, cells from its sphaeroplasts were found to be influenced by a number of factors. The most suitable conditions of regeneration were also dependent on growth medium, that is, using malt-extractglucose-yeast extract-peptone (MGYP) medium: mannitol 0.7 M, pH 6.5, 30 °C and using yeast extract-peptone-glucose (YPG) medium: sucrose 0.7 M, pH 5.0 and 30 °C. The maximum regeneration frequency was observed in YPG medium. © 1994 Springer-Verlag.
