Endangered native plant habitats and populations are rapidly disappearing because of climate and environmental changes. As a representative, the abundance of the first-class endangered wild plant, Cypripedium japonicum, has been rapidly decreasing in Korea. The purpose of this study was to evaluate the distribution of rhizosphere and endophytic fungi on C. japonicum in its native habitat. A tot...
Trichoderma harzianum is one of the most beneficial microorganisms applied on diverse crops against biotic and abiotic stresses and acts also as a plant growth-promoting fungus. Here, we report the genome of T. harzianum B97, originating from a French agricultural soil and used as a biofertilizer that can tolerate abiotic stresses.

the effects of bio-priming with different isolates of biological agent of trichoderma spp. and pseudomonas fluorescens on morphological and physiological characteristics of a bean cultivar (yaas) as well as their effects on controlling of rhizoctonia solani were investigated in two separate experiments. in the first experiment, different isolates of trichoderma including trichoderma harzianum b...
Sheath blight, causes by Rhizoctonia spp., threaten maize yield every year throughout the world. Trichoderma could degrade Rhizoctonia solani on maize mainly via competition and hyperparasitism, whereas validamycin A could efficiently inhibit the growth of R. solani via disturbing the energy system. By contrast, validamycin A is efficient but it takes effect in a short period, while Trichoderma...

In the field of natural products chemistry, a common question pertains to the authenticity of an isolated compound, i.e. are the interesting side chains biosynthesized naturally or an artefact of the isolation/purification processes? The droplet-liquid microjunction-surface sampling probe (droplet-LMJ-SSP) coupled to a hyphenated system (UPLC-UV-HRESIMS) empowers the analysis of natural product...

HIGHLIGHTS Trichoderma inoculation increased the total biomass, seedling height, root length, area, diameter, number of tips, and growth potential seedlings. increases resistance bean plant to Rhizoctonia pathogen. Among improved isolates Trichoderma, ChBD13 ChBD15 showed better performance in terms growth.
سلولز مهمترین پلی ساکارید دیواره سلولی و یکی از فراوانترین هیدروکربن های موجود در طبیعت است و در حدود 40% از توده زنده گیاهی را تشکیل می دهد.آنزیم های سلولوتیک به صورتی از سه گروه آنزیمی و به صورت سینرژیستی با همدیگر عمل می کنند و در شرایط هوازی می توانند پیوندهای گلیکوزیدی بتا 1و4 رادر سلولز هیدرولیز نموده و آن را به دی اکسید کربن و آب و در شرایط غیر هوازی به دی اکسید کربن، متان و آب تبدیل نما...
آنزیمها ( کاتالیزورهای بیولوژیک) در مصارف بیوتکنولوژیک متعدد مانند کشاورزی ، صنایع غذایی ، تصفیه پسابها و موارد دیگر کاربردهای گوناگونی دارند. آنزیم سلولاز از جمله آنزیمهای مهم صنعتی میباشد که در کشاورزی برای تجزیه ضایعات لیگنوسلولزی، در صنایع غذایی برای کاهش سلولز مواد اولیه غذایی در صنایع کاغذسازی برای نرم کردن چوب و در مصارف مختلف دیگر کاربرد دارد. در تحقیق انجام شده در این پایان¬نامه ، ...

A study of the distribution of fungal microflora was conducted on the sediment of Lake Alimini Grande in order to contribute to the evaluation of the ecosystem characteristics that can effect the process of decomposition. The isolation and identification of fungal species and ergosterol analysis were performed on sediment samples taken from 33 monitoring stations in autumn and winter. Altogethe...
The present study is an attempt to isolate and optimize the fermentation conditions of three fungus, namely Trichoderma virens, Alternaria alternata and Curvularia lunata to get pigments for the purpose of textile dyeing. Highest optical density has been achieved in potato dextrose broth at 28oC in 25 days under static conditions. Wool and silk are dyed unmordanted with very good wash and rub f...
