Twenty three cellulolytic isolates of fungi were isolated f'rum different local SOUI"ces include soil from different locations, maize cobs, wheat straw, wheat bran and some fruits, by using Czapek-Dox media with cellulose as a carbon source instead of glucose at 30 and 45°C. .. spore suspension of each isolate was prepared then it was filtered through a filtration unit (with cotton) and then by filter paper What man 1�.1, the spore count was calculated by hacmocytomctcr and it was insure of their purity. The isolations were identified according to references. The isolates were screened for their cellulolytic efficiency, fin isolates were choosed (A, D, A9, AI~' A1s) which were screened to choose one efficient isolate. It was found that the isolate (Alg) was the highest cellulases producer, it was identified as Aspergillus ,ljJ." Cellulose as a carbon source in the production media, was the selective pressure which we used to induce ccllulases, The aim of this research is to isolate cellulolytic molds and choose one efficient isolate to study the properties of their ccllulascs and the purification of them in further- studies. Using of natural cellulosic sources was a basic step to isolate and select the cellulascs production microorganisms successfully.

A series of experiments were conducted to explore the optimal conditions for cellulases production including carbon sources, nitrogen sources, initial inoculum size, initial pH and temperature. Maize car cobs, wheat straw, rice hulls, date peels, filter paper, cotton, molasses, date syrup and cellulose were used as carbon sources, some of them were treated with alkaline peroxide solution. Analyzed heated yeast, ammonium sulphate, peptone, sodium nitrate, ammonium chloride, yeast extract and corn steap liquor were used as nitrogen sources. Different inoculum sizes were used (102,103,10 lOS, 106, 107) spore/gm., also different pH were used (3,5,5.5,6,6.8,7,8) and different degrees of temp. Were used (25, 30, 35, 40, 45, 50)°C. It was found that the highest activity was achieved by using a medium containing: 1 % of treated wheat straw by alkaline peroxide, in addition to, 0.1 % molasses, 0.3% NH4C1, 0.05% MgS04.5H20, 0.05% KCI, 0.01% FeS04.7HzO and 0.1 % K2HP04 with initial pH of 8.0. The preferred size of inoculum was 1 xl05 spore/gm with a fermentation temp of 30°C. In conclusion, we can use natural sources and industrial wastes as carbon sources for cellulases production to get the target to save the environment from pollution.

The cellulytic enzymes produced by Aspergillus .ljJ.A,s by solid state fermentation were purified by four steps iuclllding precipitation with 40% ammonium sulphate followed by gel filtration cnromatogrnphy (Sephade x G-200) (6o.d.5 ern), it was eluted by phcsphate buffer (0.2 ~I) pH=8.0 with NaCI (0.05 ~I). Two proteins were found .- and B each one had two enzymes (cellulase and cellubiasej.Thc protein 13 (which contained cellulase Bel and cellubiase Bcb) was choused for further purification to homogeneity by dialysis against phosphate buffer (0.0 I M) and ion exchanger chromatogr-aphy (DEAE - Scphad ex .-50) (8x2.2 ern), the enzymes obtained were unconjugarcd ccllubiase BCb I and conjugated cellubinsc BCb2 and just one conjugated cellulase BCI. BCI and BCb2 had been choosed for further studying. their purification fold were 41.2-1 for BCI and 32.83 for BCb2, their yield were 65.25% and 35.09°;', respectively, the specific activity for them were 129.5 lJ/rng and 157.54 U/rng, respectively. In conclusion, we can say that cellulases arc enzymatic system eontaining many enzymes that may had the same molecular weight with diff'ercnt net charge, we can separate them by using above techniques in order to distinguish between them if it is exoglucanase or enrloglucnnasc.

Many extracts were achieved from ginger roots included water extract, alcoholic extract, water extract with ccllulascs produced by .sPC!•gi!!l!S, :md water extract by reflux 'extraction method. Their effects agrtin't some microorganisms such as Salmonella typltinutriunt, E. coli, Bacillus cereus, Stapliyllococcus aureus, Pseudomonas aeruginosa and Candida albicans were studied. Antimicrobial activity was estimated by Disc diffusion assay. Results were showed that the water extraction of ginger' had an antimicrobial effects against E.coli and Stuphylococus aureus at concentration 100 mglml. The average diameter for inhibition zones were 7.5 and 6.0 mm. respectively, also it was shown an antimicrobial effects against Puterugiuosa and Candida albicuns at concentrations 25,50 and 100 rug Iml . The highest effect was found against C. albicuns, which the average diameter for inhibition zone was 9 mm. On the other hand S. typhimurinm and B. cereus were not effected by this extract. The alcoholic extract had the highest antimicrobial effect against Staph. anrcus with average diameter 10.5mm, beside its effect against Piaerugins, C. albicans, S. typhimurlum and E. coli, but there was no effect against Bcereus. Using cellulases for rapture the ceI! walls cause the extraction of more antimicrobial compounds and the reflex condense extract had an antimicrobial activity against all the microorganisms tested in this study except E. coli. In conclusion, using of cellulases in extraction supports increasing the extracted compound especially antimicrobial compounds from plants because of their cellulolytic effect on plant cells, so we can use ginger extraction as an antimicrobial agent to keep food from spoilage and deterioration.
