Polyphasic identification of wild yeast strains isolated from Greek sourdoughs

Syst Appl Microbiol. 2000 Apr;23(1):156-64. doi: 10.1016/s0723-2020(00)80057-0.

Abstract

A total of forty-five wild yeast strains were isolated from five traditional Greek wheat sourdoughs. Strains were identified using the classical identification technique along with the sodium dodecyl sulfate-polyacrylamide gel electrophoresis of whole cell proteins (SDS-PAGE), Fourier transform-infrared spectroscopy (FT-IR) and the randomly amplified polymorphic DNA-polymerase chain reaction analysis (RAPD-PCR). The latter methods confirmed the classical identification. According to the results obtained, fourteen strains were identified as Saccharomyces cerevisiae strains, twenty-five as Pichia membranaefaciens strains and six as Yarrowia lipolytica.
