The antifungal activity of homologous series of 2-alkenoic and 2-bromo alkanoic acids was determined against Aspergillus niger, Trichoderma viride, Myrothecium verrucaria, and Trichophyton mentagrophytes and compared with data on analogous alkanoic and 2-fluoro alkanoic acids. The fungitoxicity of all of the series of compounds was determined by chain length, pH of the medium, and presence or a...
Treatment of grass leaves with either a purified pectin lyase of Aspergillus japonicus or a purified xylanase of Trichoderma viride could lead to the isolation of some single leaf cells. However, a mixture of pectin lyase and xylanase brought about more rapid isolation of single cells than did either of the two enzymes alone, indicating a synergistic effect. Analysis of the components released ...
The biological effectiveness of twenty-eight native isolates Trichoderma along with two known species (Trichoderma viride and harzianum) were tested against Rhizoctonia solani using dual culture technique. Of them, seven the in pot under net-house conditions wirestem disease cauliflower caused by R. solani. Inhibitory effects on statistically very significant for all Trichoderma. Thirteen exhib...
Microbial cellulases are the enzymes widely studied due to their enormous applications in biochemical industry. Among 12 fungal isolates isolated from mangrove plant debris and soil sample collected from Valanthakad Mangroves, Kerala, India, 3 of them were found to exhibit cellulolytic activity. Among them, the most potent isolate which exhibited maximum cellulolytic activity was identified as ...
Fungal laccases are involved in a variety of physiological functions such as delignification, morphogenesis, and parasitism. In addition to these functions, we suggest that fungal laccases are involved in defense mechanisms. When the laccase secreting Trichoderma viride was grown in the presence of a range of microorganisms including bacteria and fungi, laccase secretion was enhanced in respons...
−Aqueous two-phase system (ATPS) was applied for extraction bioconversion of xylan by xylanase from Trichoderma viride. Phase diagrams for poly (ethylene glycol) (PEG) and sodium citrate were determined at room temperature. The ATPS composed of 12.99% (w/w) PEG6000 and 12.09% (w/w) sodium citrate was favorable for partition of xylanase and used for extraction bioconversion of xylan. Batch hydro...
trichoderma harzianum (t39), t.virens (dar74290), t.viride (mo), t. harzianum (m) and trichderminb a commercial formulation of t. harzianum(bi) were evaluated as potential biological agents for the control of charcoal stem rot in melon caused by macrophomina phaseolina. cell-free metabolites of t. harzianum(m), t. harzianum (t39) and t. virens (dar 74290) inhibited growth of m. phaseolina compl...
در این بررسی تاثیر جدایه هایی از قارچ های آنتاگونیست (t1, t2) trichoderma harzianum (t3, t4) t. viride روی بیماری پژمردگی فوزاریومی گوجه فرنگی در اثر fusarium oxysporum f.sp.lycopersici ارتفاع و وزن تربوته ها در طرح کاملا تصادفی در 6 تیمار در گلخانه و خاک آلوده به فوزاریوم روی گوجه فرنگی رقم mony meker مورد مطالعه قرار گرفت. نتایج نشان داد که جدایه های trichoderma مخلوط با خاک آلوده به فوزاریوم...
