Four enzyme preparations produced by fungal species belonging to different genera (Aspergillus niger, Corynascus sp., Penicillium verruculosum, Trichoderma reesei) were used for synthesis of disaccharides by D-glucose (60% w/v) condensation catalyzed by -glucosidase. Effects of pH and temperature on the disaccharide synthesis were studied, and glycoside linkage patterns for enzymes from differe...
in solvo-hydrothermal method, xrd pattern was indicated presence of intermediate of ammonium octatmolybdate and ammonium tetramolybdate, which were changed to stble phase of ?-moo3 annealing. sem images were indicated nanoparticle with semispheical morphology and tem image was demonstrated nanoparticles with a diameter size of 25nm. also in impregnate method. the xrd pattern was shown high crys...
With the rising demand for renewable energy and environmental protection, anaerobic digestion of biogas technology has attracted considerable attention within the scientific community. The effect of physico-chemical pretreatment on cellulose degradation followed by fungal treatment by Aspergillus terreus and Trichoderma viride to treat cellulosic biomass for enhancing its digestibility was inve...
abstract this study aimed at investigating the impact of etymology strategy instruction on the development of vocabulary of iranian intermediate efl learners. etymology, knowledge of origin of words, roots, and affixes, has proved to be a controversial issue and a question of long debate with regard to its impact on the process of vocabulary learning. this study employed etymology strategy in ...
lentil wilt, caused by fusarium oxysporum f. sp. lentis is one of the main limiting factors to successful lentil cultivation. effect of four antagonistic fungi, namely: piriformospora indica, sebacina vermifera, trichoderma viride and trichoderma harzianum as well as combinations among them were evaluated against fusarium wilt of lentil. in in vitro experiments, the effect of the antagonistic f...
the geopolitics of afghanistan after september 11, 2001, and its impact on iranian national security
abstract u.s. attack to afghanistan after 9/11 provided opportunities for us who tried to become the dominant power after collapse of ussr and bipolar world. thinkers like fukuyama believed american liberal democrats thought would be universally accepted without resistances. liberal democracy is the best and final model of governance; in this regard, united state has moral responsibilities for...
The aim of the present work was focused on the cellulase production by Aspergillus niger using different substrates (i.e) rice bran, wheat bran, black gram bran, coconut oil cake, groundnut oil cake, and gingely oil cake. Solid state fermentation holds tremendous potentials for the production of the enzyme cellulase by Aspergillus niger. These agro industrial residues are cheap raw materials fo...
The filamentous fungus, Trichoderma viride, secretes large amounts of several cellulolytic enzymes (1). We report here the nucleotide sequence of the gene coding for exo-cellobiohydrolase (CBH), which accounts for more than 65% of the total cellulase content. This gene was isolated from a T. viride genomic library using a 30mer oligonucleotide based on the sequence of the reported CBHI gene of ...
the community dynamics of aquatic coleoptera(insecta)in one of the spring-stream habitats of bammo national park in fars province called cheshmeh-ye-ghanbari is studied as a pilot project and model for acquaintance with and furthering the biodiversity studies on fauna of iran. sixteen species-populations out of nineteen of this community were already identified for their taxonomy and for thei...
Six strain of Trichoderma (T. viride, T. harzianum, T. reesei, T. longibrachiatum, T. koningii, T. virens) were isolated and used for extracellular enzyme production. Species of Trichoderma are collected from the surrounding soil of suger beet root fields in East Iran, and held in vitro cultured PDA. TCM and TFM are used for the growth of spores and induceing the production of Cellulase. Finall...
