Ten randomized samples of materials were collected from two
places (Damascus, Homs)in Syria for isolation and identification
yeasts. These yeasts were classified morphologically according to
Barnett's and physiologically by API technique .Results
showed
that 6 isolated yeasts were Saccharomyces cerevisiae . These
isolated yeasts were screened to investigate production of biomass.
The results showed that there were differences in the ability of
isolated yeasts to produce biomass. Saccharomyces cerevisiae
isolated from date fruit was best yeast for biomass production.
Since the beginning of the twentieth century, researchers have isolated and
dentified spreaded and adapted yeasts to variow environmental conditions and
the types of the mediums in which they graw. The industrial features of the
isolated genera, e
specially those used in the food processing and the stability of
their genetic characteristics were studied. Yeasts in medical and industrial
fields were also improved.
