Open chain sophorolipids may be produced by fermentation withsp. NRRL Y-27208 or. Dimers and trimers of sophorolipids are also produced. The sophorolipds are produced by inoculating a fermentation medium comprising a carbon source and a lipid, withorspecies NRRL Y-27208, and incubating under aerobic conditions and for a period of time effective to produce an open chain sophorolipid in the medium. The sophorolipids may be subsequently recovered from the fermentation medium.

Fermentative production of sophorolipids from soybean and other vegetable oils

Itaconic acid may be produced in high yields by fermentation with a yeast,NRRL Y-30980.

Oligonucleotide probes that are specific for pathogenic yeasts and which may be used for the detection of such yeasts in biological samples are described. These probes are specific for yeast species within the clade ofand other pathogenic ascomycetous yeasts, and may be used singly or in a multiplex hybridization assay system.

Multiplex DNA identification of clinical yeasts using flow cytometry

A method is disclosed for converting D-xylose to ethanol relying on the unique ability of the yeast Pachysolen tannophilus to ferment this five-carbon sugar without the use of added enzymes. This process will be particularly useful in the production of ethanolic fuel from plant biomass.
