Fed-batch fermentation profiles of P. pastoris GS115, JQ01, JQ02, JQ03, and JQ04. Strains were fermented in inorganic salt medium containing 20 g/L glycerol, thereafter 50 g/L glucose was added into the medium at the 24 h of fermentation for inositol production. A Glycerol consumption. B Glucose consumption. C Ethanol production. D Inositol production
