Última Manejo da podridão-de-Sclerotium em pimentão em um argisolo no Amazonas Acta Amazonica Netto,Rosalee Albuquerque Coelho; Ferreira,Andréia Aline Bastos; Noda,Hiroshi. A podridão-de-Sclerotium é uma doença comum em plantas da família Solanaceae na Amazônia. Visando avaliar estratégias de manejo para esta doença em pimentão (Capsicum annuum, L. Solanaceae), foi conduzido experimento em campo em blocos casualizados com parcelas subdivididas e seis repetições, em Argissolo Vermelho-Amarelo artificialmente infestado com Sclerotium rolfsii. O tratamento principal foi a cobertura do solo (cobertura do solo com serragem ou solo nu). Os tratamentos secundários consistiram na adição ao solo de: 1) composto vegetal (3 L por cova), 2) arroz colonizado com Trichoderma harzianum (90 g por cova contendo ≈ 1,4 x 10(9) conídios g-1), 3) composto vegetal e T. harzianum nas mesmas proporções descritas anteriormente e 4) testemunha.

El moho foliar Cladosporium fulvum (Cooke 1883) produce una enfermedad que ataca el cultivo de tomate en invernadero en el Perú. Como alternativa al control de este patógeno se probó la eficiencia bajo condiciones in vitro e invernadero de cuatro hongos antagonistas: Hansfordia pulvinata (Berk y Curt 1958), Trichoderma harzianum (Rifai 1969), T. viride (Persoon 1821) y T. virens (Miller, Giddens y Foster 1963). El cultivo y crecimiento de los hongos se realizó en Agar Sabouraud para Trichoderma spp. y en Agar Jugo V8 para H. pulvinata.

E.; Pandey,Ashok. Solid state fermentation was carried out for the production of spores from Trichoderma harzianum No 53 using sugar cane bagasse pith as solid matrix and sugar cane molasses as carbon and energy source. Different nitrogen sources such as urea, (NH4)2SO4 , NH4H2PO4 and (NH4)2HPO4 were added in the media to test their effect on spores production. Among these, urea was found most useful that resulted high no of spores (1x10(9)/gDM). The influence of temperature and initial moisture of the substrate was studied through a 2² experimental plan design. No statistical differences were found within the range of 30-35ºC and 60-70% for temperature and moisture respectively. The biotechnological parameters of the process were derived from the Oxygen Uptake Rate (OUR)...

Three tubulin genes of Trichoderma harzianum were cloned followed genomic walking procedure. The tubulins showed high degree of amino acid homology with other fungal tubulins and were homologous with each other with 32 to 38% amino acid identity. Three measures for the degree of codon usage bias indicated the presence of bias in all the sequences, suggesting high expression levels in all the genes. Protein structures were modeled to provide the basis for understanding the tubulin's properties and its interactions with microtubule-associated proteins. Potential motifs were also postulated.

In this study, some physiological conditions affecting the activity of xylanase enzyme produced from Trichoderma harzianum 1073 D3 were determined. In addition, stabilization of pH and temperature in liquid and semi-solid state cultivation media were investigated. It was concluded that for maximum xylanase activity, incubation at 60°C in an enzyme incubation medium with pH 5 that contained 1 % xylan was appropriate. The stability studies showed that the enzyme was relatively stable in the pH range 3-7 and retained more than 50 % of its original activity after four months.

Organic mulches colonized with microbial biocontrol agents, termed bioenhanced mulches, were tested for their ability to reduce Phytophthora root rot of avocado (Persea americana Mill.). Benomyl-resistant mutants of Gliocladium virens (KA 230-1) and Trichoderma harzianum (KA 159.2) isolated from suppressive soils and selected as efficient antagonists of P. cinnamomi were evaluated for their ability to colonize different mulches under controlled laboratory conditions. Sudangrass and a coarse yardwaste were found to be better substrates than a fine yardwaste, woodwaste or rice hulls for biocontrol agents propagules production. The most suitable conditions for colonization were an optimum temperature of 24°C, a moisture content of 20% for sudangrass and 30%...

Exposing a wild-type culture of Trichoderma harzianum to gamma irradiation induced two stable salt-tolerant mutants (Th50M6 and Th50M11). Under saline conditions, both mutants greatly surpassed their wild type strain in growth rate, sporulation and biological proficiency against Fusarium oxysporum, the causal agent of tomato wilt disease. Tolerant T. harzianum mutants detained a capability to grow and convinced sporulation in growth media containing up to 69 mM NaCl. In comparison with their parent strain, characterization of both mutants confirmed that they have reinforced contents of proline and hydroxyproline, relatively higher sodium content compared to potassium, calcium or magnesium contents, higher level of total phenols.

Basic cultural parameters affecting mutanase production by Trichoderma harzianum F-340 in shaken flasks and aerated fermenter cultures have been standardized. The best medium for enzyme production was Mandels medium A with initial pH 5.3, supplemented with 0.3% mutan and 0.05% peptone and inoculated with 20% of the 72-h mycelium as inoculum. It was shown that mycelial mass, used in the culture medium as a sole carbon source, induced mutanase synthesis and could be utilized as an inexpensive and easily available substitute for bacterial mutan. Application of optimized medium and cultural conditions enabled us to obtain a high mutanase yield (0.6-0.7 U/mL, 2.0-2.5 U/mg protein) in a short period of time (3-5 days), which was much higher than the best...

Brown spot caused by Bipolaris oryzae is an important rice disease in Southern coast of Caspian Sea, the major rice growing region in Iran. A total of 45 Trichoderma isolates were obtained from rice paddy fields in Golestan and Mazandaran provinces which belonged to Trichoderma harzianum, T. virens and T. atroviride species. Initially, they were screened against B. oryzae by antagonism tests including dual culture, volatile and nonvolatile metabolites and hyperparasitism. Results showed that Trichoderma isolates can significantly inhibit mycelium growth of pathogen in vitro by producing volatile and nonvolatile metabolites Light microscopic observations showed no evidence of mycoparasitic behaviour of the tested isolates of Trichoderma spp. such as coiling...

Sugarcane bagasse was used as substrate for xylanase production by means of a strain of Trichoderma harzianum Rifai isolated from decaying Aspidosperma sp. (peroba) wood. The bagasse was washed, dried, milled and wetted with minimal salts medium and the cultures grown at 28 ± 2ºC for 7 days. Two extraction methods were tested for enzyme recovery: (A) Tween 80, 0.1% (v/v), in physiological saline, and (B) 50mM sodium acetate buffer, pH 5.0, under agitation (180rpm) for 15, 30 and 60min. After a single extraction, both extraction methods recovered an average of 15U/ml of xylanase activity, independent on the time of shaking. A second and third extraction recovered 10.4 and 6.6U/ml xylanase, respectively. The effect of volume size for extraction, and...

Abstract The antagonistic potential of Trichoderma strains was assayed by studying the effect of their culture filtrate on the radial growth of Sclerotium rolfsii, the causal agent of chickpea collar rot. Trichoderma harzianum-1432 (42.2%) and Trichoderma atroviride (40.3%) were found to be strong antagonists. To enhance their antagonistic potential, mutagenesis of these two selected strains was performed. Two mutants, Th-m1 and T. atroviride m1, were found to be more effective than their parent strains. The enzymatic activities of the selected parent and mutant strains were assayed, and although both mutants were found to have enhanced enzymatic activities compared to their respective parent strains, Th-m1 possessed the maximum cellulase (5.69 U/mL) and...
