abstract this study aimed at investigating the possible relationship between self-assessment in writing and self-regulation of iranian efl learners. the main purpose of the study was not only to report and inform about this relationship, but also to investigate and find practical outcomes of the incorporation of self-assessment in writing, such as improving writing skill. the research was carr...
The type species of the genus Hypocrea (Hypocreaceae, Hypocreales, Ascomycota, Fungi), H. rufa, is re-defined and epitypified using a combination of phenotype (morphology of teleomorphs and anamorphs, and characteristics in culture) and phylogenetic analyses of the translation-elongation factor 1alpha gene. Its anamorph, T. viride, the type species of Trichoderma, is re-described and epitypifie...
The decolorization of molasses by 17 different fungi in 2 media was studied. Trichoderma viride showed the highest decolorization yield (53.5%) when cultivated at 30ºC for 7 days in Medium 1 which contained the molasses which was diluted to 40 g/L in distilled water. The other Trichoderma species and Penicillium sp. also gave similar results of 40-45%. Decolorization yield was increased by addi...
abstract the present study was conducted to examine the effect of proficiency on students interaction while carrying out the grammar-based task(s) in collaboration. in particular, the study examines whether the level of proficiency affects the learners’ focus of attention to grammatical and lexical features. the study takes a further step and examines whether there is any difference in the use...
Samuels, G. J. 2006. Trichoderma: Systematics, the sexual state, and ecology. Phytopathology 96:195-206. A chronology is presented that charts the development of a genus and species concept in Trichoderma. Eighty-nine species of Trichoderma have been named, and several species of Hypocrea have been linked to unnamed Trichoderma anamorphs. Eighty-three taxa of Trichoderma and their teleomorphs, ...
A major part of Trichoderma antifungal system consists of a number of genes encoding for an astonishing variety of secreted lytic enzymes including; e.g. chitinase, cellulases and β-1,3glucanases. The present work aimed to apply the mutagenesis technique in genetically breeding program of the bioagent Trichoderma viride to enhance three effective hydrolytic enzymes in their biocontrol abilities...
بخش عمده فسفر خاک به شکل آلی است. اسید فیتیک و گلیسرو فسفات سدیم از جمله ترکیبات آلی فسفردار خاک می باشند. قارچ های خاک نقش مهمی در تبدیل این ترکیبات به فرم معدنی ایفا می کنند. در میان قارچ ها، aspergillus یکی از انواع موثر در هیدرولیز ترکیبات آلی می باشد. به منظور مطالعه توانایی جدایه هایaspergillus بر هیدرولیز بستره های اسید فیتیک و گلیسرو فسفات سدیم، آزمایشی در قالب طرح کاملا تصادفی با آرایش...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
in vitro studies with trichoderma spp., soil-borne fungal antagonists, demonstrated that a number of isolates produced volatile and non-volatile metabolites capable of inhibiting the growth and sporulation of several soil-borne plant pathogenic fungi. microscopic observations showed that t. harzianm and t. viride, isolated from soil samples from ahwaz and karaj, adversely affected the mycelial ...
Trichoderma (Ascomycetes, Hypocreales) strains that have warted conidia are traditionally identified as T. viride, the type species of Trichoderma. However, two morphologically distinct types of conidial warts (I and II) have been found. Because each type corresponds to a unique mitochondrial DNA pattern, it has been questioned whether T. viride comprises more than one species. Combined molecul...
