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.
40 samples were collected from milk from Homs to isolate the
bacteria and study their ability to produce the enzyme β-
galactosidase and diagnose isolates the most efficient in the
production of the enzyme, the results showed the presence of 25
sporeforming isolates producing the enzyme β-galactosidase , the
effectiveness of β-galactosidase was estimated using
spectrophotometer at a wavelength of 420 nm.
This research aims to study the process of natural gas condensate
stabilization by fractionation tower without reflux, and study the
effect of operating factors affecting the process such as the
operating pressure and temperature feed.
