Factors affecting the production of Saccharomyces cerevisiae from sugar beet pulp.
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.
