The following Fungal species were isolated from therhizosphere of wheat plant (TriticumaestivumL.): Trichodermaharzianum, T. viride, T. longibrachiatum, Rhizoctoniasolani, Alternariaalternata, Fusariumsolani, Fusariumoxysporum and Aspergillusniger. It was shown that all isolated fungi had the capacity to produce cellulase in solid medium (CMC- Agar), while the fungus T.viride gave the highest capability for the production of this enzyme(5.16). The fungus Rhizoctoniasolani gave less productive ratio (2.61). Quantitative test using Mandelium liquid medium showed that the fungus T.viride had the highest productivity of Cellulase(4.39 U/mL), and this fungus had greater biomass (8.96 g/L). The fungus Rhizoctoniasolani gave lower enzyme productivity(2.04 U/mL) and its biomass reached(4.65 g/L). The study of different carbon sources for the fungus T.harzianum showed that Sucrose was the best media in Cellulase productivity. It reached (3.87U/mL), and the biomass was (2.83 g/L).

It wasdetected for the ability of a local fungus A.niger, A.alternata, F.oxysporum, F.solaniandP.devirsum to produce the enzyme lipase in solidmedium including Triputyrin. The enzymic activity of P.devirsum fungus is distinction from other fungus, while the fungus A.alternata failed to produce the lipase. Then they tested quantitatively using a liquid center to determine the best conditions for best growth to fungus P.devirsum and for best produce to enzyme lipase. It indicates that corn oil is the best carbonic source for growth of fungus after 5 days of incubation, as biomass reached(15.99g/L) and effective of lipase (67.43%).And it found that the concentration of 2% of the corn oil has achieved best biomass (17.83g/L) and best production of enzyme lipase effectively(72.78%). Temperature 34 c achieved the highest biomass (18.94g/L) and best production of enzyme lipase (76.16%), and pH =7 was the best for the growth of fungus in biomass reached (21.87g/L) and production of lipase effectively (82.93%). While the nitrogenic source gave peptone biggest value to biomass (27.08 g/L) and highest production for enzyme (88.12%) in optimal conditions reached.
Ten isolates of fungi-producing amylase were isolated from six different sources (different kinds of soils - air-spoilage bread) on malt extract agar (MEA) and potato dextrose agar (PDA). Four isolates were identified in Museum of Natural History Paris- France and six isolates were identified in the College of Agriculture, Damascus University. The ability of fungal isolates for secretion aflatoxins B1, B2 and G1 was detected by thin layer chromatography technique and the quantity of toxins was determined by using electronic scanner in Syrian Atomic Agency by comparison with similar standard toxins.
The Mediterranean region is world’s leading olive growing area. A large amount of liquid waste results from olive oil extraction these wastewaters have a different effects an environmental . In this study, four fungal isolates from Samples of soil Polluted by olive mill wastewater ,this isolates follow to several types from deuteromycetes, they are follow to this types : Humicola sp., paecilomyces javanicus, Aspergillus terreus, Aspergillus flavus. They isolated them on tow media (PDA, CzA) and identify them on colony character ,Biometric and compare them with reference studies.
It was detected for the ability of a local fungus T.harzianum and A.alternate which was isolated from the rhizosphere of Wheat plant Triticum aestivum L. to produce the enzyme complex cellulase in solid medium (CMC-Agar). So it has been showed that T.harzianum and A.alternate have an ability to produce this enzyme, While the T.harzianum have higher production of cellulase than A.alternate. Then conducted a quantitative test using Mandelium liquid medium is used to determine the optimal conditions (incubation time, temperature, PH) for the best cellulase production of the two fungus studied. It was, the best conditions for its production, from T.harzianum is 7 days inchubation (3.97 U/mL), temperature 26C (4.07 U/mL) and pH=5.5 (4.19U/mL). While the best conditions for its production from A.alternate is 8 days inchubation (3.29U/mL), temperature 28C (3.15 U/mL) and pH=5.0 (3.86 U/mL). The comparison between the enzymatic activity average for both fungus , was showed superiority T.harzianum by production cellulase than fungus A.alternate. And discern that the effect of the incubation time on cellulase production from fungus T.harzianum more than its effect on cellulase production from fungus A.alternate. While effect of pH and temperature on cellulase production from fungus T.harzianum less than their effect on cellulase production from fungus A.alternate.
Fifty eight isolates of lactic acid bacteria were obtained from different local fermented foods. Isolates were identified using microscopic, cultural and biochemical tests using API strips. Results showed that 44.83% of the isolates were rod shape d and 55.17% belonged to cocci bacteria.
