1. Pyrolysis of the Caupi Bean Pod (Vigna unguiculata): Characterization of Biomass and Bio-Oil
The use of agricultural residues for the production of bio-oil is an important alternative to the use of fossil fuels. In this study, the Caupi bean pod (Vigna unguiculata) was characterized and used as biomass in the production of bio-oil. This biomass was evaluated in terms of physicochemical, morphological (scanning electron microscopy (SEM)), and thermal

2. Characterization of the solid residue generated in the detoxification step of sugarcane bagasse hemicellulosic hydrolysate and behavior in agricultural soils
ABSTRACT Overliming is an effective way of neutralizing and reducing the toxicity of the hydrolysates generated from acidic pretreatment of lignocellulosic biomass for ethanol production and others biotechnological products. Overliming generates a solid residue whose inadequate disposal may represent an environmental problem. This work aimed at the chemical

3. Feedstock and inoculum characteristics and process parameters as predictors for methane yield in mesophilic solid-state anaerobic digestion
Abstract: In this study, several linear regression models were tested to predict the cumulative 30-day methane yield produced in mesophilic solid-state anaerobic digestion, employing diverse lignocellulosic biomass sources. Data collected from 13 studies were utilized, totalizing 86 experimental points, divided into regression and validation. Models containi

4. Endophytic Actinomycetes as Potential Producers of Hemicellulases and Related Enzymes for Plant Biomass Degradation
Abstract Tailor made enzymatic preparation must be design to hydrolyze efficiently plant biomass, once that each plant biomass possesses a distinct cell wall composition. Most of actinomycetes used for plant cell wall degradation are focused on the cellulases and xylanases production. However, a wide range of enzymes must be produced for an efficient degrada

5. ELEPHANT GRASS (Pennisetum purpureum Schumach) IS A PROMISING FEEDSTOCK FOR ETHANOL PRODUCTION BY THE THERMOTOLERANT YEAST Kluyveromyces marxianus CCT 7735
ABSTRACT Elephant grass (Pennisetum purpureum Schumach) is regarded as a promising feedstock for second generation ethanol production, due to its high cellulose content, biomass production and rapid growth. The yeast Kluyveromyces marxianus CCT 7735 is capable of producing ethanol from agroindustrial residues, such as lignocellulosic biomass. Therefore, this

6. A NOVEL Scytalidium SPECIES: UNDERSTAND THE CELLULOLYTIC SYSTEM FOR BIOMASS SACCHARIFICATION
ABSTRACT In order to overcome the bottlenecks related to lignocellulosic-derived sugars, the search for more efficient enzymatic cocktails, containing a broad-spectrum of specific activities, relies on an important feature. This paper describes new enzyme activities derived from the novel strain of the Scytalidium genus isolated from the Amazonas rainforest.

7. Evaluation of endoglucanase and β-glucosidase production by bacteria and yeasts isolated from a eucalyptus plantation in the cerrado of Minas Gerais
Resumo O atual cenário ambiental e econômico global tem uma relação intrínseca com o aumento do consumo de combustíveis fósseis causados pelo desenvolvimento de tecnologias e pelo crescimento da população mundial. Assim, é necessário procurar fontes renováveis de biocombustíveis na tentativa de mitigar os efeitos dos combustíveis fósseis no me

8. Painéis de partículas elaborados do mesocarpo do dendê como alternativa ao MDF utilizado na construção civil
RESUMO A escassez dos recursos florestais integrada à necessidade de aquisição de produtos mais ecológicos demanda o uso de outros tipos de biomassa, além da madeira no setor construtivo. Diante disso, o mesocarpo do dendê - resíduo oriundo da agroindústria e com grande potencial de utilização para desenvolvimento de novos materiais - surge como al

9. Evaluation of Rice Bran as a Supplement for Production of Bioethanol by Saccharomyces cerevisiae
ABSTRACT There is an increase in researches to create alternative fuels through the use of biomass and agroindustrial lignocellulosic residues. The present study proposes the use of rice bran as source of energy with the potential to enhance bioethanol production. Using different concentrations of cells (1-5 g.L–1) and rice bran (2.5-7.5 g.L –1) with Sa

10. Genome sequence of the H2-producing Clostridium beijerinckii strain Br21 isolated from a sugarcane vinasse treatment plant
Abstract We report on the nearly complete genome sequence of Clostridium beijerinckii strain Br21, formerly isolated from a sugarcarne vinasse wastewater treatment plant. The resulting genome is ca. 5.9 Mbp in length and resembles the size of previously published C. beijerinckii genomes. We annotated the genome sequence and predicted a total of 5323 genes. S

11. Potential Bio-Oil Production from Invasive Aquatic Plants by Microscale Pyrolysis Studies
The invasive aquatic plants Eichhornia crassipes (water hyacinth), Eichhornia azurea, and Nymphaea spp. were evaluated as sources of lignocellulosic biomass for the production of bio-oil. These plants have high growth rates that can lead to various environmental problems and the production of large amounts of waste biomass. The materials were characterized i

12. Isolation and characterization of a novel endo-β-1,4-glucanase from a metagenomic library of the black-goat rumen
ABSTRACT The various types of lignocellulosic biomass found in plants comprise the most abundant renewable bioresources on Earth. In this study, the ruminal microbial ecosystem of black goats was explored because of their strong ability to digest lignocellulosic forage. A metagenomic fosmid library containing 115,200 clones was prepared from the black-goat r
