Item type:Publication, Application of Chaetomium species (Ketomium®) as a new broad spectrum biological fungicide for plant disease control: A review article(2001-12-01); - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Microbial Nanotechnology in Agricultural Applications(2026-01-01); Nanotechnology has been developed for plant disease management, and many kinds of organic nanoparticles have been developed to induce the immunity of plants, such as plant vaccines. Natural products from Chaetomium lucknowense, Chaetomium brasiliense, Chaetomium cochliodes, Chaetomium cupreum, Chaetomium elatum, Chaetomium globosum, Chaetomium siamense, Emericella nidulans, Trichoderma harzianum, and Trichoderma hamatum are reported to have antimicrobial activities against plant pathogens. In particular, Ch. siamense is a newly discovered and endophytic Chaetomium spp. that produces active metabolites. These active metabolites from Chaetomium spp., E. nidulans, T. harzianum, and T. hamatum are constructed as nanofibers for inducing plant disease immunity through phytoalexin production as nanoplant vaccines. The nanofibers are used as elicitors for the induction of immunity in plants that induce phytoalexin biosynthesis, for example, scopoletin and anthocyanidin against Phytophthora or Pythium rot and scoparone against Phytophthora or Pythium rot, capsidiol in chili against anthracnose, alpha-tomatine in tomato against Fusarium wilt, and sakuranetin and oryzalexin in rice plants against blast. The natural product nanoelicitors derived from Chaetomium spp., Emericella spp., and Trichoderma spp. help reduce disease incidence in plants. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Chaetomium: Goldmine for Sustainable Agriculture(2026-01-01); Chaetomium species are saprophytic fungi that are valuable resources for sustainable agriculture. It is found all over the world because it is durable and survives in living organisms in different climates. Chaetomium species are mostly ascomycete saprophytic fungi that survive well under stressful environmental conditions. This area has become one of the gold mines for sustainable agricultural production to maintain a balanced ecological system. The specific, potent isolates of Chaetomium were found to protect economic plants through disease, insect, and nematode control and to strongly produce cellulase to degrade organic materials in the fermentation process to increase soil nutrient fertility. All the discovered strains are recommended for acute and dermal toxicity, screening for agrochemical resistance and durability in different climates, including acidic or alkaline conditions, and growing in a wide range of temperature regimes. Research has revealed that Chaetomium species can be developed as biological fungicides, biological insecticides, biological nematicides, and natural active metabolites for plant disease control as well as biosensors for soil revitalization. These bioproducts can be used for sustainable agricultural development and maintain biological diversity in surrounding environments. Research on microbial products of Chaetomium species and other fungi for plant disease control has been conducted since 1989. After several years, 22 effective strains of Chaetomium were discovered and patented as broad-spectrum microbial fungicides, noted as Patent No. 6266, International Code: AO 1 N 25/12, and then registered as Ketomium® microbial fungicides in Thailand, Laos, Cambodia, and Vietnam and as microbial fertilizers in P. R. China. Chaetomium as a microbial fungicide and microbial fertilizer can be applied in combination with integrated pest management (IPM). It has been shown to have pathogen and disease suppressive, curative, and protective effects to control plant diseases. It is strongly recommended to prove acute and dermal toxicity, agrochemical resistance screening, acidity or alkaline conditions, and temperature regimes before developing microbial fungicides and microbial fertilizers. Chaetomium spp. are distributed worldwide and survive well under stress conditions. It serves as a natural goldmine for sustainability to maintain and revitalize the environment and preserve the natural and ecological balance in nature. Chaetomium species are broad habitats in soil, water, and endophytes with various biological properties of antagonists of phytopathogens, some insects, plant parasitic nematodes, and human pathogens, as well as the production of active metabolites, enzymes, etc. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Bis-spiro-azaphilones and azaphilones from the fungi Chaetomium cochliodes VTh01 and C. cochliodes CTh05(2008-09-29); Prabpai, SamranFour new dimeric spiro-azaplilones, cochliodones A-D (1-4), two new azaphliones, chaetoviridines E and F (5 and 6), a new epi-chaetoviridin A (7), together with five known compounds, chaetoviridin A (8), ergosterol (9), chaetochalasin A (10), 24(R)-5α,8α-epidioxyergosta-6-22-diene-3β-ol (11), and ergosterol-β-d-glucoside (12) were isolated from the fungi Chaetomium cochliodes VTh01 and C. cochliodes CTh05. Structures and stereochemistry of the atropisomers 1-3 were determined by single-crystal X-ray diffraction analysis. Compounds 5, 10, and 11 exhibited antimalarial activity against Plasmodium falciparum, while 3, 5, 6, 10, and 11 showed antimycobacterial activity against Mycobacterium tuberculosis. In addition, 5 and 6 also showed cytotoxicity against the KB, BC1, and NCI-H187 cell lines. © 2008 Elsevier Ltd. All rights reserved. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Nanofibers derived from endophytic Chaetomium brasilense for growth stimulation of rice(2022-03-01); ; Thianrat, L.Chaetomiumn brasilense PT302 was endophytically isolated from rice var Supanburi 1 and Prathumthani 80 which firstly selected for investigation to promote the growth of rice. It is morphologically and molecular phylogenetic confirmation through ITS1 and ITS4 as Ch.brasilense PT302 compared to Achaetomium strumarium (JX863914) as out group. Crude metabolites (crude hexane, crude ethyl acetate and crude methanol) at 50 ppm from Ch. brasiliense were proved to promote seed germination of rice var. Supanburi 1 and Pathumtani 80 at 7 days which found significantly higher seed germination than the non-treated control. Nanofibers constructed Ch. brasiliense promoted significantly higher seed germination, plant height and number of tillers than the non-treated control in rice var Supanburi 1 and Prathumthani 80 in 7 days at low concentration of 5 ppm planted in Chachengsao and Bangkok soil series. Nanofibers derived from endophytic Ch. brasilense is actively promoted plant growth at lower concentration than crude metabolites. It is firstly reported the natural product nanofiber constructed from endophytic Ch. brasilense to stimulate plant growth. - Some of the metrics are blocked by yourconsent settings
