Defining functional diversity for lignocellulose degradation in a microbial community using multi-omics studies. Repositório Alice
ALESSI, A. M.; BIRD, S. M.; OATES, N. C.; LI, Y.; DOWLE, A. A.; NOVOTNY, E. H.; AZEVEDO, E. R. de; BENNETT, J. P.; POLIKARPOV, I.; YOUNG, J. P. W.; MCQUEEN-MASON, S. J.; BRUCE, N. C..
Background: Lignocellulose is one of the most abundant forms of fixed carbon in the biosphere. Current industrial approaches to the degradation of lignocellulose employ enzyme mixtures, usually from a single fungal species, which are only effective in hydrolyzing polysaccharides following biomass pre-treatments. While the enzymatic mechanisms of lignocellulose degradation have been characterized in detail in individual microbial species, the microbial communities that efficiently breakdown plant materials in nature are species rich and secrete a myriad of enzymes to perform "community-level" metabolism of lignocellulose. Single-species approaches are, therefore, likely to miss important aspects of lignocellulose degradation that will be central to...

Dinámica microbiana en el compostaje de cachaza reactivada con gallinaza. Colegio de Postgraduados
Romero Yam, Lourdes Alejandra.
Se estudió la dinámica microbiana y el contenido de nitrógeno mineral y total durante el proceso de compostaje de cachaza reactivada con gallinaza. Se evaluaron cuatro tratamientos con diferentes proporciones de cachaza y gallinaza (10:0, 9:1, 7:3 y 5:5), en contenedores de 68 L durante 87 días. Las variables evaluadas fueron: temperatura, poblaciones de bacterias, hongos, microorganismos ligninolíticos, evolución de CO2, nitrógeno total, amonio y nitratos. La adición de gallinaza a la cachaza almacenada, incrementó las poblaciones de bacterias, hongos y microorganismos ligninolíticos, estos grupos microbianos mostraron poblaciones de 9.9, 5.5 y 6.4 unidades logarítmicas (ULog), respectivamente. El tratamiento 5:5 presentó una disminución en NH+4 –N (de...

Inhibitor tolerance and flocculation of a yeast strain suitable for second generation bioethanol production Electron. J. Biotechnol.
Westman,Johan O; Taherzadeh,Mohammad J; Franzén,Carl Johan.
Background: Robust second generation bioethanol processes require microorganisms able to ferment inhibitory lignocellullosic hydrolysates. In this study, the inhibitor tolerance and flocculation characteristics of Saccharomyces cerevisiae CCUG53310 were evaluated in comparison with S. cerevisiae CBS8066. Results: The flocculating strain CCUG53310 could rapidly ferment all hexoses in dilute acid spruce hydrolysate, while CBS8066 was strongly inhibited in this medium. In synthetic inhibitory media, CCUG53310 was more tolerant to carboxylic acids and furan aldehydes, but more sensitive than CBS8066 to phenolic compounds. Despite the higher tolerance, the increase in expression of the YAP1, ATR1 and FLR1 genes, known to confer resistance to...

Potential of giant reed (Arundo donax L.) for second generation ethanol production Electron. J. Biotechnol.
Lemons e Silva,Claudia Fernanda; Artigas Schirmer,Manoel; Nobuyuki Maeda,Roberto; Araújo Barcelos,Carolina; Pereira,Nei.
Background The production of second generation ethanol from lignocellulosic biomasses that have not had their potential fully explored as feedstock is of great importance. Arundo donax is one these biomasses. It is a promising grassy plant to be used as a renewable resource for the production of fuels and chemicals, because of its fast growth rate, ability to grow in different soil types and climatic conditions. The present study evaluated its use as feedstock for the production of second generation ethanol. Results Initially its chemical characterization was carried out, and a protocol for fractioning the biomass through diluted acid pretreatment followed by alkaline pretreatment was developed, providing a solid fraction which was undergone to enzymatic...

Pretreatment strategies for delignification of sugarcane bagasse: a review BABT
Karp,Susan Grace; Woiciechowski,Adenise Lorenci; Soccol,Vanete Thomaz; Soccol,Carlos Ricardo.
The valorization of agro-residues by biological routes is a key technology that contributes to the development of sustainable processes and the generation of value-added products. Sugarcane bagasse is an agro-residue generated by the sugar and alcohol industry in Brazil (186 million tons per year), composed essentially of cellulose (32-44%), hemicellulose (27-32%) and lignin (19-24%). The conversion of sugarcane bagasse into fermentable sugars requires essentially two steps: pretreatment and hydrolysis. The aim of the pretreatment is to separate the lignin and break the structure of lignocellulose, and it is one of the most critical steps in the process of converting biomass to fermentable sugars. The aim of this review is to describe different...

The Economics of Harvesting and Transporting Corn Stover for Conversion to Fuel Ethanol: A Case Study for Minnesota AgEcon
Petrolia, Daniel R..
Corn stover harvest and transport cost functions were estimated for two harvest operations for a proposed biomass-to-ethanol conversion facility located in southern Minnesota, USA. This work presents an alternative methodology to estimating corn stover quantities and harvest costs at the county level, taking into account county-specific yields, transportation distances, erosion constraints, machinery specifications, and other key variables. Monte Carlo simulation was also used to estimate the probability distribution of costs under alternative assumption on key parameters whose values vary widely in the literature. Marginal stover cost for 50MM gal/year of ethanol output was estimated at $54/dt ($0.77/gal ethanol) for the more intensive harvest method...
