عزل و تحديد هوية بكتيريا منتجة لإنزيم الفايتاز من تربة سورية

Abstract EN

Phytases are enzymes hydrolyzing phytic acid to less phosphorylated myoinositol derivatives, releasing inorganic phosphate.

Phytase has become an important industrial enzyme and is the object of extensive research.

The objective of the present study was to isolate a potential phytase producing bacterial strains from soil samples of Damascus countryside in Syria.

The phytase producing bacteria were primarily screened using PSM (phytase screening medium) plates, containing selectable media.

Further; secondary screening had been done using LPSM media.

From the (15) bacterial isolates, the isolate (C4) with high potential for phytase production was selected and identified by microscopic and traditional biochemical tests followedby (API 50 CH) system as Bacillus subtilis.
