In this study Trichoderma atroviride was selected as over producer of chitinase enzyme among 30 different isolates of Trichoderma sp. on the basis of chitinase specific activity. From this isolate the genomic and cDNA clones encoding chit33 have been isolated and sequenced. Comparison of genomic and cDNA sequences for defining gene structure indicates that this gene contains three short introns...
EVSTATIEVA, Y., M. BADALOVA, G. CHERNEV, D. NIKOLOVA and V. SAVOV, 2013. New hybrid matrix for immobilization of Trichoderma viride SL-45. Bulg. J. Agric. Sci., Supplement 2, 19: 120–122 In this work Trichoderma viride SL-45, was investigated in new a hybrid matrix by immobilizing method. Vegetative culture of this strain was immobilized in four variations of sol-gel hybrid silica materials, co...
Trichoderma has gained maximum attention as biocontrol agent due to the fact that it is effective against a large number of soil-borne plant pathogenic fungi, suppressive effects on some root nematodes without adversely affecting beneficial microbes like Rhizobium and capable of promoting growth of certain crops. There are two major methods of inoculum production of Trichoderma spp. viz., solid...
The diversity of Trichoderma spp. was investigated in alkaline soils of pistachio orchards at different geographic areas in Kerman province, Iran. A total of 161 Trichoderma isolates were obtained and identified at the species level by their morphological characters and sequence analysis of their internal transcribed spacer (ITS) and tef1-α genomic regions. Totally, five species of Trichoderma ...
The enzymatic hydrolysate of wastepaper was evaluated for its cellulase-inducing capability and production characteristics in continuous culture of Trichoderma reesei RUT C30. Under the study conditions, i.e., pH 5.0, temperature 25 degreesC, and typical medium C:N ratio, the apparent cell yield constant was found to be 0. 76 (g of dry cell weight/g of reducing sugar), and the maximum specific ...
This paper describes and illustrates two new species, Trichoderma pleurotum and T. pleuroticola, associated with green mold disease of oyster mushroom in Korea.
Several Trichoderma virens (syn. Gliocladium virens) strains have good biocontrol activity against Rhizoctonia solani on cotton but lack some of the commercially desirable characteristics found in other Trichoderma species. In an attempt to combine these desirable characteristics, we used a highly effective biocontrol strain of T. virens in protoplast fusions with a strain of T. koningii, which...
Five new polyketide derivatives, 7-O-methylkoninginin D (1) and trichodermaketones A-D (2-5), together with four known compounds, koninginins A, D, E, and F, were isolated from the marine-derived fungus Trichoderma koningii. Trichodermaketones A (2) and B (3) are unprecedented polyketides with a bistetrafuran-containing tricyclic skeleton. The chemical structures and absolute configurations of ...
understanding the function of trichoderma species in the control of phytophthora drechsleri in pistachio orchards is very important. in this study, the effects of liquid extra-cellular secretions and volatile compounds secreted by 27 isolates of trichoderma harzianum, t. crassum, t. koningii, t.aureoviride, t. asperellum, t. brevicompactum, t.longibrachiatum and t. virens were investigated on ...
Background The ascomycete fungus Trichoderma reesei is the predominant source of enzymes for industrial conversion of lignocellulose. Its glycoside hydrolase family 7 cellobiohydrolase (GH7 CBH) TreCel7A constitutes nearly half of the enzyme cocktail by weight and is the major workhorse in the cellulose hydrolysis process. The orthologs from Trichoderma atroviride (TatCel7A) and Trichoderma har...
