In this study, effects of single and combined applications biocontrol agents; Trichoderma spp. (T. atroviride, T. virens) plant growth promoting rhizobacteria (Pseudomonas koreensis, Bacillus subtilis) on growth, wilt disease severity caused by Verticillium dahliae defence-related enzymes (peroxidase, polyphenol oxidase, phenylalanine ammonium lyase β-1,3 glucanase) eggplant, were investigated....

Mutualistic fungal endophytes infect many grass species and often confer benefits to the hosts such as reduced herbivory by insects and animals. The physiological interactions between the endophytes and their hosts have not been well characterized. Fungal-secreted proteins are likely to be important components of the interaction. In the interaction between Poa ampla and the endophyte Neotyphodi...

sugar beet pulp is one of the sugar industries by-products which can be used for cellulase enzyme production, enzymatic saccharification, and alcohol production due to its high percentage of lingo-cellulosic content. trichoderma spp. is an important fungus that produces a wide range of cellulytic enzymes. in this study, cellulase enzyme was produced by placing sugar beet pulp in trichoderma fer...

Hybrid (1 -33 -4)-P-glucanases which contain an N-terminal region derived from the Bacillus amyloliquefaciens enzyme and a C-terminal region of the closely related B. macerans enzyme may exhibit a thermostability superior to both parental enzymes. A systematic series of hybrid enzymes were constructed in order to delineate the amino acid residues that affect protein stability. Hybrid enzymes wi...

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 ...

an experiment was conducted to evaluate the effect of different levels of germinated barley (gb) on live performance and carcass traits in broiler chickens. the experiment lasted for 5 weeks starting from 7 days of age and ending at 42 days of age. chicks (ross 308) were fed six dietary treatments including a corn–soy diet (corn diet), a barley–soy diet (barley diet), a barley diet plus enzymes...

The extracellular endo-1,4-beta-glucanase components of Ruminococcus flavefaciens FD-1 were analyzed by high-performance liquid chromatography (HPLC) by using DEAE ion-exchange, hydroxylapatite, and gel filtration chromatography and polyacrylamide gel electrophoresis (PAGE). Two endo-1,4-beta-glucanase peaks were resolved by DEAE-HPLC and termed endoglucanases A and B. Carboxymethyl cellulose (...

ABSTRACT- This study was designed to investigate the effects of adding different levels of date presscakes (DP), with and without enzyme supplementation (ES), on the ileal digestibility and growth performance of broiler. A completely randomized design containing 2 × 5 factorial arrangement of treatments (with and without enzyme supplementation and 5 levels of DP) was used. The enzyme complex co...

Two 2 × 2 factorial experiments were conducted to investigate the interaction between cereal type (wheat v. barley) and exogenous enzyme supplementation (with or without) on odour and ammonia emissions (experiment 1) and growth performance (experiment 2) in grower-finisher pigs. The enzyme supplement used contained endo-1, 3 (4) - β- glucanase (EC 3.2.1.6) and endo-1, 4 - β-xylanase (E.C 3.2.1....

In a previous paper, we reported the first stopped-flow experiments on a Bacillus licheniformis 1,3-1,4-beta-glucanase [Abel, Planas and Christensen (2001) Biochem. J. 357, 195-202]. It was shown that the pre-steady-state kinetics of the 1,3-1,4-beta-glucanase using the substrate 4-methylumbelliferyl 3-O-beta-cellobiosyl-beta-D-glucoside may be explained by a reaction scheme involving an induce...
