After morphological and biochemical studies, 11 strains of Actinobacteria were isolated, mostly of them belong to the genus Streptomyces, these strains were used later to detect their ability in cellulase and xylanase enzymes production during the initial detection depending on the diameter of the halo transparent around cultured colonies on solid media.

The purpose of the research is to provide a methodology for a fair distribution of subsidies, which helps the Syrian government in improving the living level of the Syrian family. This methodology is based on studying, classifying and ordering the living levels of the families depending on predefined indicators
We aimed in this study to evaluate the effectiveness of Syrian propolis on some bacterial strains isolated from Al-Assad hospital in Latakia, to estimate its antimicrobial activity. Thus, we studied two propolis samples from two regions in the Syrian coast, and prepared ethanolic extracts of propolis (EEP) with different concentrations (0.5%, 1%, 5%, 10%, and 20%). Then we tested these extracts on four strains of bacteria (Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, and Acinetobacter baumannii), using pore method on Muller Hinton Agar. As we observed, the bacteria showed diverse susceptibility to the extracts and the most susceptible bacterium was Staphylococcus aureus which was sensitive to all concentrations and especially for EEP 20%. However, the least affected bacteria were E. coli and Pseudomonas, as the 0.5% and 1% EEP had no efficacy. On the other hand, there were little differences in antimicrobial activity between the two samples of propolis.
Eighty four bacterial strains, isolated from various local soils, vegetables and fruits in decomposition were screened to detect pectinase using citrus pectin as the sole carbon source according to solid plate assay. Results showed that 13 strains showed ability to produce pectinase depolymerization in assay plate as evidenced by clear hydrolization halos formed around the colonies. Four strains among them presented considerable pectinolytic activity since haloes with more than 3 cm in diameter were formed. Based on morphological and chemical characteristics, 3 strains were classified as Bacillus subtilis and 1 strain as Bacillus cereus. The Bacillus subtilis (B30) strain which had the biggest halo and produced high activity of the enzyme was incubated with polygalactuoronic acid under different conditions of temperature and pH levels. This strain showed high activity to produce polygalauoronase at 52°C and pH 9.0. It was concluded that there is an ability to produce locally alkaline polygalactuoronase which can be used for manufacturing purposes, especially for treatment the west products of food processing units to remove pectins.
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.
Faggarat: are an old system to invest groundwater near the surface of the land. This system spread near dry regions. The research aims to define the Faggarat and their local distribution, the possibility to revive them in Syria revealing their ben efits economically, socially, historically, archeologically and environmentally because they promote aquatic and agricultural Perpetual Development in arid regions.
