The microbial conversion of lignocellulosic biomass for biofuel production represents a renewable alternative to fossil fuels. However, the discovery of new microbial enzymes with high activity is critical for improving biomass conversion processes. While attempts to identify superior lignocellulose-degrading enzymes have focused predominantly on the animal gut, biomass-degrading communities in...

An anaerobic sequencing batch reactor (ASBR), seeded with a biomass inoculum that previously had not been exposed to the macrolide antimicrobial tylosin (mixture of Tylosin A, B, C, and D), was operated for 3 months with swine waste without Tylosin A and for 9 months with swine waste containing Tylosin A at an average concentration of 1.6 mg/L. When swine waste with tylosin was fed to the ASBR,...

Lignocellulosic biomass is a vast and underutilized resource for the production of sugars and biofuels. However, the structural complexity of lignocellulosic biomass and the need for multiple pretreatment and enzymatic steps for sugar release renders this process economically challenging. Here, we report a novel approach for direct, single container, exogenous enzyme-free conversion of lignocel...

13 14 The potential of microalgae as a source of biofuels and as a technological solution for 15 CO2 fixation is subject to intense academic and industrial research. In the perspective of 16 setting up massive cultures, the management of large quantities of residual biomass and the 17 high amounts of fertilizers must be considered. Anaerobic digestion is a key process that can 18 solve this was...

BACKGROUND There is currently considerable interest in developing renewable sources of energy. One strategy is the biological conversion of plant biomass to liquid transportation fuel. Several technical hurdles impinge upon the economic feasibility of this strategy, including the development of energy crops amenable to facile deconstruction. Reliable assays to characterize feedstock quality are...

Well-drilling fluid and a number of the known components (barite, clay, Aldacide, Surflo, and Dowicide, were tested for effects on the biomass and community structure of the microbiota that colonize marine sands exposed for eight weeks to running ambient seawater. Shading the microbiota from light depressed the microflora without a significant effect on the biomass, while well-drilling fluids l...

Yeast biomass as well as biomass enriched with trace minerals have been demonstrated to be useful in improving animal health and growth performance. In this work, process for the production of Saccharomyces cerevisiae biomass enriched with manganese, a microelement with antioxidant properties in the form of high bioavailable Mn-protein complex, has been studied. Th e infl uences of media compos...

Lignocellulosic material can be used as biomass for power generation via biogas if it is pretreated to improve the anaerobic hydrolysis step, by either solubilising the hemicellulose (total reducing groups, TRG) or removing lignin (Lig), with consequent exposition of the cellulose fibre to anaerobic degradation. We evaluated the effects of acid, alkaline, and hydrothermal pretreatments on sugar...

Cellulose is a primary structural component of plants and one the most abundant polymers on Earth. Degradation this recalcitrant plant biomass an important process in global carbon cycle can potentially provide feedstock for biofuels. Fungi bacteria are organisms able to breakdown biomass-derived cellulose. Anaerobic bacteria, present cellulose degrading ecosystems, such as compost piles, soils...
