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 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 کاملUptake and utilization of vitamin B6 and its phosphate esters by Escherichia coli.
Escherichia coli KG980, a vitamin B6 auxotroph derived from E. coli K12, utilized the three unphosphorylated forms of vitamin B6, more or less effectively, for growth, but did not utilize the three phosphate forms at concentrations ranging from 10(-7) to 10(-5) M in the minimum medium of Davis and Mingioli. The bacterium, however, utilized the phosphate forms, although less effectively than the...
متن کاملMolecular identification of Pichia guilliermondii, Debaryomyces hansenii and Candida palmioleophila
Traditional phenotypic methods and commercial kits based on carbohydrate assimilation patterns are unable to consistently distinguish among isolates of Pichia guilliermondii, Debaryomyces hansenii and Candida palmioleophila. As result, these species are often misidentified. In this work, we established a reliable method for the identification/differentiation of these species. Our assay was vali...
متن کاملComparative utilization of paraffins by a Trichosporon species.
Utilization of normal and isoparaffins, separately and in mixtures, by a Trichosporon sp. was investigated. From a mixture of normal paraffins and isoparaffins, the organism consumed straight-chain paraffins, leaving the branched paraffins relatively unchanged. When offered separately, the highest utilization of n-alkanes by the organism was obtained in the range of undecane to octadecane; n-pe...
