Production of \-mannanases by Trichoderma harzianum E58
Applied Microbiology and Biotechnology, 1990The extracellular mannanase and endoglucanase activities of Trichoderma harzianum E58 were followed during growth of the fungus on 1% (w/v) mannose, Avicel, locust bean gum, konjac powder or the water-soluble fraction from stream-treated white spruce (SWS). Peak galactomannanase activities of 0.60 IU/ml and 0.66 IU/ml were detected in culture filtrates

Extracellular laccases in ascomycetesTrichoderma atroviride andTrichoderma harzianum
Folia Microbiologica, 2002Laccase activity in Trichoderma harzianum and in our own isolate Trichoderma atroviride was correlated with the production of the green pigment in conidial spores. The laccases of the two fungal species exhibit comparable kinetic parameters, pH optima and thermal sensitivity but differed in physiological properties, such as their catalytic activity ...

Hypocrea lixii, the teleomorph of Trichoderma harzianum
Mycological Progress, 2002Cultures derived from ascospores of Hypocrea lixii (= H. nigricans, H. lentiformis) produced the morphological species Trichoderma harzianum in pure culture. Trichoderma harzianum, the most commonly found species of the genus, is also one of the most species frequently used in biocontrol of plant pathogens.

Production and regulation of cellulases in Trichoderma harzianum
Applied Microbiology and Biotechnology, 1984The highest production of extracellular cellulases (Filter paper activity, Carboxymethyl cellulase and β-glucosidase) by Trichoderma harzianum was achieved on delignified wheat straw. Glycerol at a concentration of one per cent strongly repressed the formation of all the cellulolytic components.

Antifungal alkyl pyrones of Trichoderma harzianum
Transactions of the British Mycological Society, 1987Two strains of Trichoderma harzianum were both found to produce the volatile metabolites 6-n-pentyl-2H-pyran-2-one and 6-n-pentenyl-2H-pyran-2-one. The pentyl analogue, the major product, demonstrated potent inhibitory properties to a wide range of fungi and considerably reduced the rate of damping off in lettuce seedlings by Rhizoctonia solani ...

Trichoderma harzianum metabolites pre-adapt mushrooms to Trichoderma aggressivum antagonism.
Mycologia, 2003Trichoderma spp. is the cause of green mold, a disorder that affects cultivated mushrooms. The aims of the study were to establish whether improvement of mushroom resistance to Trichoderma aggressivum could be obtained by inducing reaction mechanisms before contact with the pathogen and whether this ability was species or strain dependent.

Trichoderma harzianum: a biocontrol agent against Bipolaris oryzae
Mycopathologia, 2007Rice brown spot, caused by Bipolaris oryzae, can be a serious disease causing a considerable yield loss. Trichoderma harzianum is an effective biocontrol agent for a number of plant fungal diseases. Thus, this research was carried out to investigate the mechanisms of action by which T.

Production of Bioaugmented Composts with Trichoderma harzianum
Agro ProductividadObjective: To develop a bioaugmented compost in a pile system through the addition of submerged fermentation products derived from Trichoderma harzianum. Methodology: Biodegradation kinetics of newspaper were monitored over a 30-day period in a cylindrical air-lift bioreactor inoculated with Trichoderma harzianum (IrV6S1C7), aiming to generate fungal ...

Trichoderma frianum sp. nov., a wood-inhabiting species from India, is described based on morphological characteristics and molecular phylogenetic analyses. This taxon is congruent with the morphological species concept of T. harzianum sensu lato, characterized by pyramidal conidiophores and cruciate phialidic whorls with fewer than five phialides ...
