تعرض الغطاء النباتي الطبيعي في سورية لانحسار بعض الأنواع النباتية و انقراض أنواع أخرى، مما يحتم ضرورة حصر الأنواع الموجودة و تصنيـفها تمهيداً لحمايتهـا و الاستفادة منها في برامج التحسين الوراثي. لذا فقد هدف هذا البحث إلى دراسة معمقة للتنوع الحيوي النباتي في المنطقة البازلتيـة غـرب حمص، مع التركيز على القرنيات البرية و جراثيم الريزوبيوم المتعايشة معها. أظهر المسح النباتي للمنطقة وجود 365 نوعاً وعائياً تنتظم في 202 جنس و 51 فـصيلة، منهـا 15 نوعاً متوطناً. و سجل 12 نوعاً لم تشر الفلورات الحديثة إلى وجودها في سورية بل خصته في لبنان. كما أضافت هذه الدراسة 3 أنواع جديدة لم يرد ذكرها في سورية و لبنان سابقاً. و قـد تـم تحديـد الانتمـاء الجغرافي و الأهمية الاقتصادية للأنواع المجموعة، و اقترحت مفاتيح تصنيفية لأنواع أهـم الفـصائل فـي المنطقة. كما درست العقد البكتيرية في 10 أنواع من القرنيات البرية تنتمي لـ 10 أجناس مختلفة، حيث عزلت منها سلالات الريزوبيوم و جرت زراعتها و دراسة صفاتها الشكلية ثم حفظـت بوصـفها سـلالات نقيـة .
Some species of the Syrian Flora were waned, other were extincted. therefore, it was so nessesary to make a releve for restrict and classify the survival species in order to put them under conserving & improvement genetic program. The aim of this research was to study the plant diversity in West Homs; one of important basaltic region in Syria, and to concentrate on the wild legumes and the Rhizobium strains which cohabit with. A plant survey was carried out showed the existence of 365 species belong to 202 genera and 51 families, 15 species are endemic.12 species not observed previously in Syria but are found in Lebanon were recorded,in addition another 3 species not listed at all neither in Syria nor in Lebanon were mentioned. The geobotanical attributes and the economical importance of the gathered species were determined.as so as systematic keys of the most important families were suggested...The root nodules of 10 species belong to 10 genera of wild legumes were studied. Rhizobium strains were isolated and cultured in vitro. The morphologic characters were studied microscopy. The pure strains were reserved by refrigerator.

أجري هذا البحث في مخابر كلية الزراعة بجامعة الفرات قسم علوم الأغذية وفي مخابر هيئة الطاقة الذرية بدمشق وقد هدف إلى عزل وتعريف بعض سلالات بكتريا حمض اللبن من الحليب الخام للنوق والماعز الشامي بالإضافة إلى دراسة بعض الخصائص الكيميائية والتصنيعية للسلالات المعزولة وذلك في عامي ( 2010و 2011)
Enterobacter sakazakii is considered an opportunistic pathogen that has
been associated with severe lethal infections especially in neonates, elderly, and
Immunocompromised adults. E. sakazakii is a Gram negative, facultative
anaerobes rod-shaped
bacterium. It belongs to the family Enterobacteriaceae
and genus Enterobacter.
Although we don’t know the natural habitat of this bacteria we find that it
exists in high rate in herbs and spices which indicates that plant may be this
natural habitat.
Study of basaltic rocks in the Rastan region showed the presence of
many morphological and petrographic varieties compatible with
rocks of Alhesen castle region. Chemical analyses of studied rocks
proved to be alkaline rocks with sodic-potassic na
ture. Rotten parts
of studied rocks considered an important source of civilian
installations, paving roads, and as materials for manufacture of
cement, in addition to their academic importance in Petrological,
paleogeographic, and tectonic studies.
The aim of this study is to use the measured values of the magnetic
susceptibility in the classification of the basaltic rocks and their different
differentiation degrees as an additional discrimination factor to the
geochemical analyses, which we
re applied on the basalts of southern and southeastern
Syria. So the magnetic susceptibility of ٢٠٤ specimens sampled from all
the ٧ basaltic groups in Qasr Shbeeka area in addition to ٦٢ specimens
sampled from three groups from outside the studied area were measured. This
led to the determination of all the magnetic susceptibility ranges, their mean
values and their standard deviation of the basaltic rocks in the area.
This research was conducted at the Faculty of Agriculture, Department of
Food Science laboratories to isolate lactic acid bacteria from some Syrian milk
products (milk, yogurt, cheese) and determine some morphological,
physiological characteristic and the ability of these isolates to ferment sugars.
