Mixture of Xylose and Glucose Affects Xylitol Production by Pichia guilliermondii: Model Prediction Using Artificial Neural Network
Production of several yeast products occur in presence of mixtures of monosaccharides. To study effect of xylose and glucose mixtures with system aeration and nitrogen source as the other two operative variables on xylitol production by Pichia guilliermondii, the present work was defined. Artificial Neural Network (ANN) strategy was used to athematically show interplay between these three c...
متن کاملExpression of the inulinase gene from the marine‐derived Pichia guilliermondii in Saccharomyces sp. W0 and ethanol production from inulin
It has been confirmed that Saccharomyces sp. W0 can produce high concentration of ethanol. In this study, the INU1 gene cloned from the marine-derived Pichia guilliermondii was transformed into uracil mutant of Saccharomyces sp. W0. The positive transformant Inu-66 obtained could produce 34.2 U ml⁻¹ of extracellular inulinase within 72 h of cultivation. It was found that 15.2 U of inulinase act...
متن کاملValidation of the species Pichia guilliermondii.
Many species of yeasts exist in nature in haploid form. If strongly heterothallic, strains of such species produce no ascospores when tested individually. They do mate if sexually reactive strains of opposite sex are mixed on a sporulation medium. In 1952, L. J. Wickerham and K. A. Burton (J. Bacteriol. 63:449, 1952) reported that all strains of an imperfect form known variously as Dematium cho...
متن کاملUtilization of Xylan by Yeasts and Its Conversion to Ethanol by Pichia stipitis Strains.
Yeasts able to grow on d-xylose were screened for the ability to hydrolyze xylan. Xylanase activity was found to be rare; a total of only 19 of more than 250 strains yielded a positive test result. The activity was localized largely in the genus Cryptococcus and in Pichia stipitis and its anamorph Candida shehatae. The ability to hydrolyze xylan was generally uncoupled from that to hydrolyze ce...
متن کاملProduction and Utilization of Ethanol by the Homoacetogen Acetobacterium woodii.
Acetobacterium woodii formed ethanol as a fermentation product in addition to acetate when the phosphate concentration of the medium was between 0.2 and 8.4 mM. Considerable amounts of alanine were also found (2 to 11 mM). Supplementation with phosphate caused a shift to acetate as the only end product. Ethanol could also serve as a substrate for A. woodii. The fermentation yielded predominantl...
