The use of synthetic fungicides to control fungal diseases has growing limitations due eco-toxicological risks. Therefore, it is necessary replace or integrate high risk chemicals with safer tools for human health and environment. Consequently, research on the selection, evaluation, characterization, biocontrol agents (BCAs) consistently increased in last decades. BCA formulates, particularly some countries, are still scarce coping demand their sustainable agricultural management. To foster...
Soil-inhabiting fungal pathogens use chemical signals released by roots to direct hyphal growth towards the host plant. Whether other soil microorganisms exploit this capacity for their own benefit is currently unknown. Here we show that endophytic rhizobacterium Rahnella aquatilis locates hyphae of root-infecting pathogen Fusarium oxysporum through pH-mediated chemotaxis and uses them as highways efficiently access colonize plant roots. Secretion gluconic acid (GlcA) R. in rhizosphere leads...
More than 200 yeasts were selectively isolated from microbial populations on the surface of different fruits. Fifty these isolates tested against blue mould ( Penicillium expansum ) wounded apples. Isolates LS-11 Rhodotorula glutinis and LS-28 Cryptococcus laurentii most effective antagonists. They further evaluated at 20IC fruits (apples, pears, strawberries, kiwi table grapes) several main post-harvest pathogens Botrytis cinerea, expansum, Rhizopus stolonifer Aspergillus niger 4IC apples...
The aim of this work was to investigate the major mechanisms involved in antagonism BO7, a novel strain Bacillus amyloliquefaciens isolated from orchard soil, against vascular wilt fungus Fusarium oxysporum f. sp. lycopersici (Fol). BO7 markedly reduced incidence Fol on tomato plants and displayed strong vitro inhibitory activity Fol. Scanning electron microscopy demonstrated ability cells adhere fungal hyphae efficiently colonize roots. low molecular weight fraction culture filtrate high...
Wine contamination with ochratoxin A (OTA) is due to the attack of wine grapes by ochratoxigenic Aspergillus carbonarius and spp. section Nigri. Four A. pullulans strains, AU14-3-1, AU18-3B, AU34-2, LS30, are resistant actively degrade in vitro. The less toxic alpha aminoacid L-beta-phenylalanine were major degradation products, deriving from cleavage amide bond linking these two moieties OTA. same strains studied further as biocontrol agents on laboratory experiments. Three four...
Three new lipopeptides (1-3) were isolated from the organic extract of Bacillus amyloliquefaciens strain (BO7). These compounds represented major constituents (>60%) total cell lipids extractable with CHCl(3)/MeOH (2:1). Elucidation their chemical structure was carried out by spectroscopic analyses, including 1D and 2D NMR spectroscopy, mass spectrometry (MS), secondary ion (MS/MS), along degradation. The are members surfactins family based on heptapeptide Glu-Leu-Leu-Ala-Asp-Leu-Leu,...
Fusaric acid (FA) is one of the first secondary metabolites isolated from phytopathogenic fungi belonging to genus Fusarium. This molecule exerts a toxic effect on plants, rhizobacteria, and animals, it plays crucial role in both plant animal pathogenesis. In metal chelation by FA considered possible mechanisms action. Here, we evaluated different nitrogen sources, iron content, extracellular pH cellular signalling pathways production siderophores pathogen Fusarium oxysporum (Fol). Our...
O ensino híbrido, também conhecido como blended learning, emergiu uma abordagem pedagógica que combina práticas presenciais e digitais, oferecendo flexibilidade personalização no processo de ensino-aprendizagem. Essa metodologia tem ganhado destaque, sobretudo contexto contemporâneo, onde a integração tecnologias educacionais é essencial para enfrentar os desafios pós-pandemia as demandas inovação na educação. Por essa razão, este estudo se propõe analisar perspectivas do híbrido educação...
Diante da crescente complexidade das cadeias de suprimentos modernas e pressões organizacionais por maior eficiência, a Teoria Restrições (TOC) emerge como uma abordagem estratégica para identificar gerenciar gargalos críticos que limitam o desempenho dos sistemas logísticos. Este estudo tem objetivo analisar aplicabilidade TOC na otimização processos logísticos, destacando seus benefícios, desafios integração com outras metodologias, Lean Seis Sigma. Os resultados obtidos evidenciam ganhos...
Management of Xylella fastidiosa subsp. pauca (Xfp) presents significant challenges due to the lack genetic resistance in major crops, pathogen variability and development against main antimicrobial compounds, effective chemical compounds for control. Traditional bactericides EU are restricted, copper-based products increasingly limited environmental impacts. In this study antibacterial side effects some commercial fertilizers Xfp were evaluated. These products, containing metal ions (mainly...
A contabilidade ambiental tem ganhado crescente relevância na gestão empresarial, impulsionada por demandas regulatórias e pressões dos stakeholders para maior transparência sustentabilidade. No entanto, sua implementação ainda enfrenta desafios relacionados à padronização, custos operacionais riscos como o greenwashing. Este estudo objetivo analisar a influência da no desempenho sustentável das empresas, meio de uma revisão sistemática literatura. Para isso, foram analisados 15 estudos...
A educação socioemocional (ESE) tem sido amplamente reconhecida como essencial para o desenvolvimento integral dos indivíduos, ultrapassando as habilidades cognitivas tradicionais. No entanto, sua implementação efetiva enfrenta desafios a falta de clareza conceitual, resistência institucional e capacitação docente insuficiente. pandemia da COVID-19 reforçou necessidade estratégias que integrem emocional cognitivo. Assim, este estudo objetivo analisar publicações científicas sobre ESE,...
A carreira dos técnicos administrativos em educação (TAEs) no Brasil é regulamentada pela Lei nº 11.091/2005, que estabelece critérios para progressão funcional e valorização salarial. No entanto, estudos apontam desafios como a lenta desigualdades salariais, impactam diretamente motivação o desempenho servidores. Em dezembro de 2024, Medida Provisória 1.286/2024 introduziu mudanças significativas na estrutura do Plano Carreira Cargos Técnico-Administrativos Educação (PCCTAE), alterando...
