Influence of temperature and pH on xylitol production from xylose by Debaryomyces hansenii.
The production of xylitol from concentrated synthetic xylose solutions (S(o) = 130-135 g/L) by Debaryomyces hansenii was investigated at different pH and temperature values. At optimum starting pH (pH(o) = 5.5), T = 24 degrees C, and relatively low starting biomass levels (0.5-0.6 g(x)/L), 88% of xylose was utilized for xylitol production, the rest being preferentially fermented to ethanol (10%...
متن کاملLipids of Debaryomyces Hansenii.
Merdinger, Emanuel (Roosevelt University, Chicago, Ill.), and Edward M. Devine, Jr. Lipids of Debaryomyces hansenii. J. Bacteriol. 89:1488-1493. 1965.-The separation of neutral lipids and phospholipids from the lipid extract of Debaryomyces hansenii NRRL Y-1448 was accomplished by using a single column packed with silicic acid. The neutral lipids comprised 67%, and the phospholipids 33%, of the...
متن کاملCasein digestion by Debaryomyces hansenii isolated from cheese.
To understand the possible proteolytic contribution of yeast during cheese ripening, Debaryomyces hansenii 212 was isolated from commercial blue-veined cheese and incubated in a medium containing casein. Growth and casein degradation were recognized at the cheese-ripening temperature. Proteolytic activity was found in the intracellular fraction, and the enzyme, which was attached to the cell wa...
متن کاملExtrinsic allergic alveolitis induced by the yeast Debaryomyces hansenii.
A 65-yr-old female developed cough, fever and dyspnoea following repeated exposure to a home ultrasonic humidifier. High-resolution computed tomography showed ground-glass opacity in both lung fields. Arterial blood gas analysis gave an oxygen tension of 8.38 kPa (63 Torr). Pulmonary function testing revealed restrictive ventilatory impairment with a reduction in the diffusing capacity. The dia...
متن کاملActivation of fermentation by salts in Debaryomyces hansenii.
The presence of 1.0 M KCl or NaCl during growth of Debaryomyces hansenii results in increased ethanol production. An additional increase of fermentation was observed when the salts were also present during incubation under nongrowing conditions. Extracts of cells grown in the presence of salt showed increased alcohol dehydrogenase and phosphofructokinase activities, indicating that these enzyme...
