1. Isolation of fungi from dung of wild herbivores for application in bioethanol production
ABSTRACT Producing biofuels such as ethanol from non-food plant material has the potential to meet transportation fuel requirements in many African countries without impacting directly on food security. The current shortcomings in biomass processing are inefficient fermentation of plant sugars, such as xylose, especially at high temperatures, lack of ferment

2. Laccase produced by a thermotolerant strain of Trametes trogii LK13
Thermophilic and thermotolerant micro-organisms strains have served as the natural source of industrially relevant and thermostable enzymes. Although some strains of the Trametes genus are thermotolerant, few Trametes strains were studied at the temperature above 30 °C until now. In this paper, the laccase activity and the mycelial growth rate for Trametes

3. Inmovilización de enzimas lignocelulolíticas en nanopartículas magnéticas
Due to the need for more efficient, economical and environmentally-friendly technological processes, the use of enzymes has increased. However, reuse of enzymatic hydrolytic complex is required. The immobilization of enzymes provides a basis for stability and allows their reuse reflected in aspects of economic feasibility. Magnetic nanoparticles are a promis

4. Secretion of laccase and manganese peroxidase by Pleurotus strains cultivate in solid-state using Pinus spp. sawdust
Pleurotus species secrete phenol oxidase enzymes: laccase (Lcc) and manganese peroxidase (MnP). New genotypes of these species show potential to be used in processes aiming at the degradation of phenolic compounds, polycyclic aromatic hydrocarbons and dyes. Hence, a screening of some strains of Pleurotus towards Lcc and MnP production was performed in this w

5. Efficient production of lignocellulolytic enzymes xylanase, β-xylosidase, ferulic acid esterase and β-glucosidase by the mutant strain Aspergillus awamori 2B.361 U2/1
The production of xylanase, β-xylosidase, ferulic acid esterase and β-glucosidase by Aspergillus awamori 2B.361 U2/1, a hyper producer of glucoamylase and pectinase, was evaluated using selected conditions regarding nitrogen nutrition. Submerged cultivations were carried out at 30 ºC and 200 rpm in growth media containing 30 g wheat bran/L as main carbon

7. Obtenção de inoculante e de coquetel enzimático lignocelulolítico a partir de comunidades microbianas termofílicas / Acquisition of an inoculant and a lignocellulolytic enzymatic cocktail from thermophilic microbial communities
Three thermophilic lignocellulolytic microbial communities were selected by enriched method with continual subcultivation at 55 C. One community was selected from cow manure compost, another from decaying sugar cane bagasse, and the last one was obtained by mixing aliquots of the culture suspension from the first two. Those communities were able to degrade a

8. BioconversÃo de resÃduos agroindustriais por micro-organismos do bioma amazÃnico produtores de enzimas lignocelulolÃticas / Bioconversion of agro-industrial residues by microorganisms from the Amazon biome producers of lignocellulolytic enzymes
A biomassa lignocelulÃsica contÃm altos teores de celulose e outros polissacarÃdeos em sua constituiÃÃo quÃmica, podendo ser hidrolisados em aÃÃcares fermentescÃveis. A geraÃÃo de resÃduos agroindustriais anual tem crescido resultando no acÃmulo de resÃduos que contribuem para a poluiÃÃo do meio ambiente e na perda de materiais que possuem po

9. Lignocellulolytic enzyme production of Pleurotus ostreatus growth in agroindustrial wastes
The mushroom Pleurotus ostreatus has nutritional and medicinal characteristics that depend on the growth substrate. In nature, this fungus grows on dead wood, but it can be artificially cultivated on agricultural wastes (coffee husks, eucalyptus sawdust, corncobs and sugar cane bagasse). The degradation of agricultural wastes involves some enzyme complexes m

10. Xylanase and cellulase activities during anaerobic decomposition of three aquatic acrophytes
Enzymatic activity during decomposition is extremely important to hydrolyze molecules that are assimilated by microorganisms. During aquatic macrophytes decomposition, enzymes act mainly in the breakdown of lignocellulolytic matrix fibers (i.e. cellulose, hemicellulose and lignin) that encompass the refractory fraction from organic matter. Considering the im

11. Use of vinasse and sugarcane bagasse for the production of enzymes by lignocellulolytic fungi
Recentemente o uso de material lignocelulolítico tem mostrado um importante avanço na produção de biocombustíveis. O bagaço e a vinhaça são resíduos oriundos do processamento da cana de açúcar e contem um alto teor de carbono, que geralmente é usado na co-geração de energia e ração animal. Três linhagens de Pleurotus e um ascomiceto, Trichod

12. Aproveitamento do caroço do açaí como substrato para a produção de enzimas por fermentação em estado sólido
The açaí agroindustry is the most important productive chains in northern Brazil. The residues in the marketing of açaí consists mainly of its pits, which are discarded in landfills and waterways without any treatment. A possible application to açaí pits is its use as substrate for solid state fermentation (SSF) for the production of lignocellulolytic
