“…With repeated use of these chemicals leave harmful residues and can lead to the development of resistance in pathogens [1]. Hence, interest has been developed for safer non chemical methods to control disease that is effective and causes less risk to human health and environment [2].…”

The biocontrol measures against pathogens are widely recognized as a step towards organic agriculture. In the present study, nine species of endophytic fungi and four plant pathogenic fungi were tested against antagonistic activity of a root endophyte, Trichoderma viride. Out of nine endophytic fungi, eight were inhibited. The inhibitory effect was maximum against Alternaria sp. and Pythium sp. The minimum zone was noticed against Nigrospora sp. after 14 days of incubation. It showed no inhibitory effect against an isolate of Aspergillus sp. and overgrew it after 9 days of incubation. T. viride showed antagonistic activity against all the four plant pathogenic fungi. The antagonistic zone was highest against Colletotrichum capsici and lowest was observed in Alternaria solani after 14 days of incubation. The study suggests the potential of an endophytic strain of fungus and it may be used in biocontrol programmes of plant diseases in the region.

“…It is a secondary opportunistic invader, a fast growing fungus, a strong spore producer, a source of cell wall degrading enzymes and an important antibiotic producer (Vinale et al, 2008). Trichoderma species are readily isolated from soil by all available conventional methods, largely because of their rapid growth, abundant condition and present in nearly all soils and other diverse habitats (Kubicek and Harman, 2002;Harman, 2006).…”

Trichoderma spp. are known as a rich source of secondary metabolites with biological activity belonging to a variety of classes of chemical compounds. These fungi also are well known for their ability to produce a wide range of antibiotic substances and to parasitize other fungi. In search for new substances, which might act as anticancer agents, the overall objective of this study was to investigate the cytotoxic effects of Trichoderma harzianum and Trichoderma asperellum cultural filtrates against human cervical and breast cancer cell lines (HeLa and MCF-7 cells respectively). To achieve this objective, cells were exposed to 20, 40, 60, 80 and 100 mg/ ml of both T. harzianum cultural filtrate (ThCF) and T. asperellum cultural filtrate (TaCF) for 24h, then the cell viability and the cytotoxic responses were assessed by using trypan blue and 3-

“…So far, Trichoderma spp. is among the most studied BCAs fungal and it is commercially marketed as biopesticides and biofertilizers [6][7][8]. Its entomopathogenicity is close related to its ability of synthesize hydrolytic enzymes.…”

Effect of pH and Temperature on Enzyme Activity of Chitosanase Produced Under Solid Stated Fermentation by Trichoderma spp.

et al. 2011

Trichoderma strains were extensively studied as biocontrol agents due to their ability of producing hydrolytic enzymes, which are considered key enzymes because they attack the insect exoskeleton allowing the fungi infection. The present work aimed to evaluate the ability of chitosanase production by four Trichoderma strains (T. harzianum, T. koningii, T. viride and T. polysporum) under solid stated fermentation and to evaluate the effect of pH and temperature on enzyme activity. pH strongly affected the enzyme activity from all tested strains. Chitosanase from T. harzianum and T. viride presented optimum activity at pH 5.0 and chitosanase from T. koningii and T. polysporum presented optimum activity at pH 5.5. Temperature in the range of 40-50°C did not affect enzyme activity. T. polysporum was found as the most promising strain to produce chitosanase with maximal enzyme activity of about 1.4 IU/gds, followed by T. viride (*1.2 IU/gds) and T. harzianum (1.06 IU/gds).
