This paper describes a study of the variability measured composition for single bulk sugarcane bagasse conducted across eight laboratories using similar analytical methods, with purpose determining expected variation compositional analysis performed by different laboratories. The results show good agreement within laboratory, but greater when are compared among These interlaboratory variabilities do not seem to be associated specific method or technique any piece instrumentation. summary...
O conceito de saúde é muito amplo, pois sofre influência vários aspectos, como os hábitos vida, nesse sentido sabemos que diferentes podem predispor a doenças ou até mesmo proteger delas. Este artigo objetiva analisar dados sobre vida entre adolescentes do Brasil. Para tal análise foi desenvolvido um estudo transversal com coleta no DATA UNICEF e contextualização da dos parâmetros analisados o indivíduo. A coletados revelou brasileiros não estão adequados, impactando negativamente na...
The possible roles played by yeasts in attine ant nests are mostly unknown. Here we present our investigations on the plant polysaccharide degradation profile of 82 isolated from fungus gardens Atta and Acromyrmex species to demonstrate that found may play role making nutrients readily available throughout garden detoxification compounds be deleterious ants their fungal cultivar. Among screened, 65% exhibited cellulolytic enzymes, 44% pectinolytic activity while 27% 17% possess enzyme...
Actinomycetes bacteria associated with leafcutter ants produce secondary metabolites antimicrobial properties against Escovopsis, a fungus specialized in attacking the gardens of fungus-growing ants, which denies their food source. Because previous studies have used fungi isolated from but not ant integument, aims present study were to isolate actinomycetes cuticle Acromyrmex spp. and quantify inhibition abilities filamentous fungal species carried by these ants. The results demonstrated...
After decades of intensive searching for antimicrobial compounds derived from actinobacteria, the frequency isolation new molecules has decreased. To cope with this concern, studies have focused on exploitation actinobacteria unexplored environments and symbionts plants animals. In study, twenty-four strains isolated workers Trachymyrmex ants were evaluated antifungal activity towards a variety Candida species. Results revealed that seven inhibited tested Streptomyces sp. TD025 presented...
This work aimed to produce enzymatic fungi extracts with hydrolytic and oxidative activities hydrolyze lignocellulosic biomasses efficiently. For this, the Trichoderma reesei Panus lecomtei were co-cultured using vegetable oil palm decanter cake, wheat bran, cottonseed cake as substrates in submerged fermentation. T. P. showed partially compatible positive interaction on plates. The co-cultures respond positively variations of temperature inoculum interval, generating responsible for higher...
Summary Attine ants maintain an association with antibiotic‐producing A ctinobacteria found on their integuments. Evidence supports these bacteria as auxiliary symbionts that help to defend the fungus gardens against pathogens. Using P seudonocardia strains isolated from T rachymyrmex ants, we tested whether inhibitory capabilities of such are restricted E scovopsis parasites infect this ant genus. Twelve were in vitro bioassays derived ( n = 1) and leaf‐cutting 3). Overall, significant...
Two new mass spectrometry methods, MALDI-TOF MS and hydrophilic interaction UHPLC-ESI-MS, were developed for the characterization of cellulose-active lytic polysaccharide monooxygenases, expanding analytical toolbox study these enzymes.
There is an urgent need for improvements in animal production, particularly ruminants, such that more sustainable and efficient processes are developed obtaining nutritious feeds. Filamentous fungi can add value to residual plant biomass, may also have the potential produce metabolites enrich biomasses used nutrition, converting them into nutraceutical sources. Thus, this work, filamentous fungal fermentation of ruminant feed commonly Brazil was performed, enrichment bioactive tested. For...
Abstract The use of residual lignocellulosic biomass appears as an opportunity to obtain high added value products like enzymes. present work goal was select basidiomycetes capable metabolizing empty fruit bunches (EB) or sludge decanter (SD) from the oil palm industry produce enzymatic cocktails. First, eight macro‐basidiomycetes strains Brazilian cerrado were selected based on genomic DNA analyses out initial group 30. and two ascomycetes (commercial mushrooms) cultured ligninolytic...
This work investigates the effects of co-culture between filamentous fungus Panus lecomtei and yeast Sporidiobolus pararoseus in production laccases. The variations time interval inoculum volume S. co-cultures with P. stimulated laccase production, reaching its highest activity at nearly 2960.7 ± 244 U/mL a maximum point 120 h 2.0% (v/v), respectively. Further application pretreated sugarcane bagasse hydrolysis was performed, using extract added to an enzyme mixture from Trichoderma reesei...
This work focused on obtaining fermented oil cake (cotton or Jatropha) via macrofungi growth with potential characteristics for animal feed formulations, such as the presence of extracellular enzymes, bioactive (ergosterol and antioxidants), detoxification antinutritional compounds. The concentration phorbol esters was reduced by four in Jatropha seed (JSC) to non-toxic levels. At least two efficiently degraded free gossypol cottonseed (CSC). Fermentation Coriolopsis sp. INPA1646 Tyromyces...

Abstract The sustainable use of residual lignocellulosic biomass is an opportunity to help overcome the global need reduce emission pollutants as well depletion fossil fuel resources and increasing energy demands. This study aimed establish a deconstruction process oil palm empty fruit bunches (EFBs), employing hydrothermal biological pretreatments. Initially, yields cellulose, hemicellulose, lignin, extractives ashes resulting from autohydrolysis raw EFBs were measured. pretreatment...
O sorgo sacarino tem se destacado como matéria-prima alternativa na produção de etanol, atuando forma complementar ao cultivo da cana-de-açúcar em período entressafra. Visando explorar o potencial deste material, empregando caldo BRS 511, foi avaliado comportamento três leveduras comerciais (CAT-1, PE-2 e SA-1) quatro ciclos fermentativos. Utilizando a levedura CAT-1, foram conduzidas também as fermentações dos caldos das variedades 506, 507, 508. Foram retiradas amostras até completo...
A aplicação de celulases imobilizadas na desconstrução biomassas possibilita melhorias para este processo, como o reuso enzimas e maior quantidade açúcar produzido por massa do biocatalisador. O objetivo deste trabalho foi desenvolver um biocatalisador hidrólise holocelulosede braquiária. Celulases extrato bruto comercial foramimobilizadas ligação covalente em quitosana ativada com glutaraldeído.As atividades foram (em U/g): 0,92 (α-celulose); 8,69(celobiose); 4,74(carboximetilcelulose)...
Materiais lignocelulósicos contêm polissacarídeos que podem ser convertidos em açúcares fermentescíveis para obtenção de Etanol 2G e outros bioprodutos. Para essa conversão, são necessários processos pré-tratamento hidrólise enzimática eficientes eficazes. O objetivo deste trabalho foi otimizar as condições ácido bagaço cana-de-açúcar visando obter maiores quantidades destes açúcares. As experimentais do foram estabelecidas por um planejamento DCCR 2
