جمعت 10 عينات من مواد مختلفة من محافظتي دمشق و حمص لعزل و تشخيص الخمائر مورفولوجياً حسب Barnett و فيزيولوجياً باستخدام تقنية
API و أظهرت النتائج وجود 6 عزلات من خميرة Saccharomyces cerevisiae
, تمت غربلة العزلات المصنفة حسب إنتاجها للكتلة الحيوية, فبينت النتائج تباين السلالات المدروسة في إنتاجها للكتلة الحيوية, و أعطت السلالة المعزولة من التمر أعلى إنتاج للكتلة الحيوية.
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.
