ABSTRACT
Three nitrogen sources, peptone and tryptone as organic sources, and ammonium sulphate as inorganic source for a different incubation periods (72, 84 or 96 hours) at pH 10 or 6.8, at different salinity levels were used. The maximum productivity for total, external and internal glycerol was found in case of using peptone, pH 10 at 14% (w/v) NaCl after 96hs. incubation period (698, 220, 478 mg/L) respectively. Immobilization enhance yeast growth and glycerol production. The productivity of Nylon immobilized cells was higher than immobilized cells on glass wool.
