Lipids 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 کاملDraft genome sequence of salt-tolerant yeast Debaryomyces hansenii var. hansenii MTCC 234.
Debaryomyces hansenii is one of the most halotolerant species of yeast, and the genome sequence of D. hansenii strain CBS767 is already available. Here we report the 11.46-Mb draft genome of D. hansenii strain MTCC 234, which is even more halotolerant than strain CBS767. Comparative analysis of these sequences would definitely provide further insight into the halotolerance of this yeast.
متن کاملInfluence 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 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 کاملDebaryomyces hansenii strains differ in their production of flavor compounds in a cheese-surface model
Flavor production among 12 strains of Debaryomyces hansenii when grown on a simple cheese model mimicking a cheese surface was investigated by dynamic headspace sampling followed by gas chromatography-mass spectrometry. The present study confirmed that D. hansenii possess the ability to produce important cheese flavor compounds, primarily branched-chain aldehydes and alcohols, and thus importan...
