title: Factors affecting the production of Saccharomyces cerevisiae from sugar beet pulp.
abstract: Factors affecting the production of S. cerevisiae from sugar beet pulp after acid hydrolysis were investigated. Maximum yield and economic coefficient were obtained at sugar concentration of 7.15% after an incubation period of 72 h at 30 degrees C and pH 6.0 using a mixture (1:1) of ammonium sulphate and ammonium nitrate (0.2 g/g sugar) as nitrogen source. HPLC analysis of beet pulp hydrolyzate showed that hexoses especially glucose serve as the most suitable sugars with regard to S. cerevisiae activity.
