Abstract A survey for species of the genus Trichoderma occurring as endophytes Coffea, and mycoparasites coffee rusts ( Hemileia ), was undertaken in Africa; concentrating on Cameroon Ethiopia. Ninety-four isolates were obtained during this study: 76 healthy leaves, stems berries and, 18 directly from colonized rust pustules. phylogenetic analysis all used a combination three genes: translation elongation factor-1α tef1 rpb2 cal selected isolates. GCPSR criteria recognition species;...
Despite the numerous benefits plants receive from probiotics, maintaining consistent results across applications is still a challenge. Cultivation-independent methods associated with reduced sequencing costs have considerably improved overall understanding of microbial ecology in plant environment. As result, now, it possible to engineer consortium microbes aiming for health. Such synthetic communities (SynComs) contain carefully chosen species produce desired microbiome function. Microbial...
Production of pigments by filamentous fungi is gaining interest owing to their use as food colourants, in cosmetics and textiles, because the important biological activities these compounds. In this context, objectives study were select pigment-producing fungi, identify based on internal transcribed spacer sequences, evaluate growth pigment production selected strains four different media, characterize major coloured metabolites extracts. Of fungal strains, eight identified Aspergillus...
Fusarium tupiense, the main causal agent of mango malformation in Brazil, is described through a combination morphological, biological and molecular markers. This new species belongs to Gibberella fujikuroi complex (GFSC) has an anamorph morphologically similar mangiferae F. sterilihyphosum. tupiense can be differentiated from other G. on basis sexual crosses, amplified fragment length polymorphism (AFLP) markers partial sequences tef1 tub2 genes. Female fertility for field isolates appears...
Sclerotinia sclerotiorum is an important plant pathogen with worldwide distribution that causes severe economic losses of various agricultural crops such as soybean. This fungus normally controlled synthetic chemical fungicides pose risks to the environment, and can be harmful human health, they also induce resistance in pests. The aim this study was investigate potential Trichoderma asperelloides a biocontrol agent towards white mold disease on soybeans crops. antagonism two strains T. (T25...
During surveys conducted in South America and Africa to identify natural fungal enemies of coffee leaf rust (CLR), Hemileia vastatrix, over 1500 strains were isolated, either as endophytes from healthy tissues Coffea species or mycoparasites growing on pustules. Based morphological data, eight isolates—three isolated wild semiwild five coffee, all Africa—were provisionally assigned the genus Clonostachys. A polyphasic study their morphological, cultural molecular characteristics—including...
Abstract Background Azo dyes in textile effluents represent a particular health concern because they include azo groups (NN), which are reactive with DNA nucleic acids. The enzymes produced by white rot fungi can biodegrade broad range of environmental contaminants. This work addresses this concentrating on novel and effective optimal conditions for Trametes cingulata to produce oxidative the capacity decolorize dye red 239. Results A multifactorial experimental design optimized enzymatic...
The increased interest in secondary metabolites (SMs) has driven a number of genome sequencing projects to elucidate their biosynthetic pathways. As result, studies revealed that the metabolite gene clusters (SMGCs) greatly outnumbers detected compounds, challenging current methods dereplicate and categorize this amount on larger scale. Here, we present an automated workflow for genetic dereplication analysis metabolism genes fungi. Focusing rich genus Aspergillus, SMGCs across genomes into...
A fungal strain of Aspergillus niger was recovered from sediments collected in the Northeast coast Brazil (Pecém's offshore port terminal). Cultivation different growth media yielded a new ester furan derivative, 1, along with malformin A1, C, cyclo (trans-4-hydroxy-L-Pro-L-Leu), (trans-4-hydroxy-L-Pro-L-Phe), (L-Pro-L-Leu), (L-Pro-L-Phe), pseurotin D, A, chlovalicin, (L-Pro-L-Tyr) and (L-Pro-L-Val). Compound 1 cytotoxic against HCT-116 cell line, showing IC50 = 2.9 μg/mL (CI 95% 1.8 to 4.7 μg/mL).
Three new isoaigialones, A, B, and C (1–3), along with aigialone (4), were isolated from the crude EtOAc extract of a Phaeoacremonium sp., an endophytic fungus obtained leaves Senna spectabilis. The structures these compounds elucidated based on analysis spectroscopic data. Compounds 2 4 active against phytopathogenic fungi Cladosporium cladosporioides C. sphaerospermum. This is first report metabolites produced by associated S.
A fungal strain of Aspergillus sp. (BRF 030) was isolated from the sediments collected in northeast coast Brazil, and cytotoxic activity its secondary metabolites investigated against HCT-116 tumour cell line. The cytotoxicity-guided fractionation extracts this fungus cultured potato-dextrose-sea water for 14 days at room temperature yielded hetero-spirocyclic γ-lactams pseurotin (1), D (2) FD-838 (7), alkaloids fumitremorgin C (5), 12,13-dihydroxy (6), methylsulochrin (4)...
Abstract The cytotoxic activities of extracts (50 μg/ml) from 48 fungal strains, recovered sediments Pecém's offshore port terminal (Northeast coast Brazil), against HCT‐116 colon cancer cell lines were investigated. most promising extract was obtained strain BRF082, identified as Dichotomomyces cejpii by phylogenetic analyses partial RPB2 gene sequence. Thus, it selected for bioassay‐guided isolation the compounds. Large‐scale fermentation BRF082 in potato dextrose broth, followed...
Abstract Early blight, caused by Alternaria solani and A . grandis , severely affects potato crops around the world, few management options apart from intensive fungicide use are available. In this work, we tested whether biocontrol treatments with different species of mycoparasitic fungus Clonostachys could reduce early blight severity on foliage pot‐grown potatoes cultivar Ágata, affect survival sporulation causal pathogen Twenty isolates five were screened in a preliminary trial, nine...
Bovine mastitis caused by S. aureus has a major economic impact on the dairy sector. With crucial need for new therapies, anti-virulence strategies have gained attention as alternatives to antibiotics. Here we aimed identify novel compounds that inhibit production/activity of hemolysins, virulence factor associated with severity. We screened Bacillus strains obtained from diverse sources showing anti-hemolytic activity. Our results demonstrate lipopeptides produced spp. completely prevented...
