GOCHEV, V. K. and A. I. KRASTANOV, 2007. Isolation of laccase producing Trichoderma spp. Bulg. J. Agric. Sci., 13: 171-176 Based on its dye decolorization activities four Trichoderma strains were screened as laccase producers. The strains were identified as T. atroviride, T. longibrachiatum, T. reesei, and T. viride. It was determined that it was expedient to screen laccase producing Trichoderm...

Nineteen isolates of Trichoderma viride and Trichoderma harzianum obtained from rhizosphere soil of plantation crops, forest soil and agricultural fields of North Bengal region were studied using RAPD and ITS-PCR. The genetic relatedness among eleven isolates of T. viride and eight isolates of T. harzianum were analyzed with six random primers. RAPD profiles showed genetic diversity among the i...

The efficacy of four fungal bioagents viz., Trichoderma hamatum, Trichoderma harzianum, Trichoderma viride, Gliocladium virens and two bacterial bioagents namely Pseudomonas fluorescens and Bacillus subtilis were evaluated against the chickpea vascular wilt pathogen, Fusarium oxysporum f.sp. ciceri in vitro condition using Dual Culture Technique. Among the fungal bioagents, T. harzianum produce...

Fungi in the genus Trichoderma have been used for the production of lytic enzymes and to control a wide range of plant pathogenic fungi. In the last years, much progress has been made in elucidating the molecular biology of Trichoderma spp. The objective of this chapter is to provide a summary of data concerning size and organization of the genome and gene structure in Trichoderma spp., mainly ...

The study is attempted to investigate the production of potent lipase from groundnut oil mill fungi. The fungi was isolated and identified as Trichoderma sp. Lipolytic activity of Trichoderma sp. was preliminarily confirmed by Rhodamine B method, lipase production was carried out using mineral medium. The extracellular protein concentration and lipase enzyme activity (7.83U/ml) was maximum at 4...

In the screening for new melanin synthesis inhibitors, we found a novel isonitrile inhibitor, MR304Afrom the culture broth of Trichoderma harzianum. There were someisonitrile antibiotics that were reported to have been isolated from Trichoderma sp. 1 ~ 4) and trichoviridin, one of these isonitriles, showed a melanin biosynthesis inhibitory activity5). In this paper we described the fermentation...

The present study was conducted to observe the effect of increased osmolality of basic tris extender supplemented with trehalose and sucrose on post-thawing quality (motility, progressive motility, viability, the rate of acrosome abnormality, total abnormality and membrane integrity) of Markhoz goat spermatozoa. Fresh semen samples were evaluated for motility and sperm concentration. Only semen...

Lifting and carrying heavy loads occur frequently among ironworkers and result in high prevalence and incidence rates of low back complaints, injuries and work-disability. From a health perspective, little information is available on the effect of team lifting on work demands and workload. Therefore, the objective of this study was to compare the effects of team lifting of maximally 50 kg by tw...

BACKGROUND Subculturing has been extensively used to attenuate human pathogens. In this work we studied the effect of continuous subculturing of Nocardia brasiliensis HUJEG-1 on virulence in a murine model. METHODS Nocardia brasiliensis HUJEG-1 was subcultured up to 130 times on brain heart infusion over four years. BALB/c mice were inoculated in the right foot pad with the bacteria subcultur...
