the aim of present study was to investigate the effect of individual and co-inoculation of trichoderma species and arbuscular mycorrhizal fungi (amf) on growth, mycorrhization, population of trichoderma, and wilt disease severity in pigeon pea (cajanus cajan l millsp). three species of trichoderma, namely, t. harzianum (th), t. virens (tr), and t. viride (tv) and consortium of amf (myc; mixture...

Endoglucanase I (EGI) from Trichoderma viride HK-75 catalyzes not only hydrolysis but also transglycosylation reactions of cellooligosaccharides. In order to characterize the important amino acid residues in transglycosylation of EGI, three Tyr, one Leu, and two Glu residues of EGI were replaced by Trp or Asp. The seven resulting EGI, except for L200W, had reduced activities toward carboxymethy...

HREE DIFFERENT newly isolated marine fungi were subjected ........to 18S rRNA gene partial sequence analysis. The resulting sequences showed that the isolates belong to Fusarium solani, Trichoderma viride and Aspergillus niger. The isolates have the ability to utilize some petroleum hydrocarbons such as hexane, motor oil and diesel oil. The tested fungi could grow up to 7 days, especially on me...

Sweet or bell pepper is a member of the Solanaceae family and is regarded as one of the most popular and nutritious vegetable. Blight, in the form of leaf and fruit blight, has been observed to infect bell pepper crops cultivated at the horticulture farm in Rajasthan College of Agriculture, Udaipur, India. Based on disease severity, we attempted to curb this newly emerged problem using differen...

At least two different signalling pathways have been identified that result in clearly distinguishable volatile profiles in response to pathogens and herbivores in the lima bean Phaseolus lunatus. Alamethicin, a voltage-gated ion-channel-forming peptide from Trichoderma viride, is a potent inducer of volatile biosynthesis in the lima bean. Unlike elicitation with cellulysin or herbivore damage,...

Secondary metabolites produced by Trichoderma viride, a deuteromycetes fungus, under submerged culture condition were formulated and evaluated for oviposition attractancy against gravid females of Culex quinquefasciatus mosquito. At a concentration of 10 g ml-1 the formulation showed remarkable attractancy with an oviposition active index (OAI) of +0.52. When the oviposition attractancy of the...

The taxonomic analysis of 114 actinomycete strains isolated from water of the River Nile and its bottom sediments showed that most of the water isolates belonging the genus Streptomyces. As well as, the majoring of the sediment isolates belongs to the genus Micromonospora. The overwhelming majority of Streptomyces species are Str. antibioticus, Str. aunlatus, Str. violaceus and Str. antimycotic...

An endo-a-D-(1 + 3).glucanase capable of hydrolyzing various ~(1 -+ 3).glucans has been isolated and purified from the culture filtrate of the cellulolytic fungus Trichoderma viride, and its specificity has been examined. Of the compounds tested only those with oc-(1 ---f 3).glucosidic linkages were attacked, and the enzymatic hydrolysis occurred with retention of configuration of the anomeric ...
