Formic acid is one of the major inhibitory compounds present in hydrolysates derived from lignocellulosic materials, the presence of which can significantly hamper the efficiency of converting available sugars into bioethanol. This study investigated the potential for screening formic acid tolerance in non-Saccharomyces cerevisiae yeast strains, which could be used for the development of advanc...

BACKGROUND Although outdoor cultivation systems have been widely used for mass production of microalgae at a relatively low cost, there are still limited efforts on outdoor cultivation of carbohydrate-rich microalgae that were further used as feedstock for fermentative bioethanol production. In particular, the effects of seasonal changes on cell growth, CO2 fixation, and carbohydrate production...

Rubberwood (Hevea brasiliensis), a potential raw material for bioethanol production due to its high cellulose content, was used as a novel feedstock for enzymatic hydrolysis and bioethanol production using biological pretreatment. To improve ethanol production, rubberwood was pretreated with white rot fungus Ceriporiopsis subvermispora to increase fermentation efficiency. The effects of particl...

Global economic development has led to the widespread use of fossil fuels, and their extensive resulted in increased environmental pollution. As a result, significantly more attention is being paid issues alternative renewable energy sources. Bioethanol production from agro-industrial byproducts, residues, wastes one example sustainable production. This research aims develop process cost model ...

Bioethanol has been developed as an alternative biofuel. Elephant grass is one of the lignocelluloses that can be used a source bioethanol. The bioethanol fermentation process should improved along with its economic competitiveness to promote wider application. This study aims investigate and evaluate best scheme biethanol (standalone) combination by-products through technoeconomic analysis. me...

Here, we present the draft genome sequence of Saccharomyces cerevisiae BG-1, a Brazilian industrial strain widely used for bioethanol production from sugarcane. The 11.7-Mb genome sequence consists of 216 scaffolds and harbors 5,607 predicted protein-coding genes.

Bioethanol is an energy source that can be used to reduce the use of fossil fuels. It has some advantages such as biodegradable, and non-toxic because main ingredients come from biomass produce fewer pollutants. Anabaena sp. Cyanobacteria ingredient bioethanol, its are it does not compete with food, growth fast contains carbohydrates. The purpose this study was analyze carbohydrate content stag...

Saccharomyces cerevisiae normally cannot assimilate mannitol, a promising brown macroalgal carbon source for bioethanol production. The molecular basis of this inability remains unknown. We found that cells capable of assimilating mannitol arose spontaneously from wild-type S. cerevisiae during prolonged culture in mannitol-containing medium. Based on microarray data, complementation analysis, ...

Contrary to the case of the United States where a systematic management of the RD&D on lignocellulosic ethanol prevails, in Europe the research works remain fragmented despite the efforts made by the European Union and in few member states. In most of the European countries, sustainable lignocellulosic resources may not be widely available in the future for bioethanol production due to the poss...

The objective of this research was to investigate biodegradation of water hyacinth (Eichhornia crassipes) to produce bioethanol using dilute-acid pretreatment (1% sulfuric acid) results in high hemicellulose decomposition and using yeast (Pachysolen tannophilus) as bioethanol producing strain. A maximum ethanol yield of 1.14g/L with coefficient, 0.24g g; productivity, 0.015g lh was comparable t...
