Abstract Employing Illumina Hiseq whole genome metagenome sequencing approach, we studied the impact of Trichoderma harzianum on altering the microbial community and its functional dynamics in the rhizhosphere soil of black pepper (Piper nigrum L.). The metagenomic datasets from the rhizosphere with (tre...

Biocontrol potential of saline- or alkaline-tolerant Trichoderma asperellum mutants against three pathogenic fungi under saline or alkaline stress conditions

Guo, Ruiting; Wang, Zhiying; Huang, Ying; Fan, Haijuan; Liu, Zhihua.

Braz. j. microbiol; 49 (supl.1), 2018

ABSTRACT Salinity and alkalinity are major abiotic stresses that limit growth and development of poplar. We investigated biocontrol potential of saline- and alkaline-tolerant mutants of Trichoderma asperellum to mediate the effects of salinity or alkalinity stresses on Populus davidiana × P. alba var. p...

Electron. j. biotechnol; 26 (), 2017

Background: Xylanases are considered one of the most important enzymes in many industries. However, their low thermostability hampers their applications in feed pelleting, pulp bleaching, and so on. The main aim of this work was to improve the thermostability of Trichoderma ressei xylanase 2 (Xyn2) by in...

Isolation and expression of two polyketide synthase genes from Trichoderma harzianum 88 during mycoparasitism

Yao, Lin; Tan, Chong; Song, Jinzhu; Yang, Qian; Yu, Lijie; Li, Xinling.

Braz. j. microbiol; 47 (2), 2016

Abstract Metabolites of mycoparasitic fungal species such as Trichoderma harzianum 88 have important biological roles. In this study, two new ketoacyl synthase (KS) fragments were isolated from cultured Trichoderma harzianum 88 mycelia using degenerate primers and analysed using a phylogenetic tree. The ...
