Increased expression of the oxidative pentose phosphate pathway and gluconeogenesis in anaerobically growing xylose-utilizing Saccharomyces cerevisiae

Microbial Cell Factories, 2009
Background Fermentation of xylose to ethanol has been achieved in S. cerevisiae by genetic engineering. Xylose utilization is however slow compared to glucose, and during anaerobic conditions addition of glucose has been necessary for cellular growth. In

Effects of Lycium barbarum Residue Substituting Dietary Maize on Fecal Microbiota and Growth Performance of Crossbred Simmental Cattle

Animal Research and One Health, EarlyView.
The bioactive substances we extracted from Lycium barbarum residue (LBR) have a typical polysaccharide structure. When 1.80% LBR was used to replace maize in the diet, the average daily gain of rossbred Simmental was significantly increased, and anti‐inflammatory ability was improved. In addition, LBR improved the fecal microbial composition, increased

Determination of D-Xylose in Urine for the D-Xylose Absorption Test

Clinical Chemistry, 1969
Abstract A method is described for the determination of D-xylose in urine which is based on the specific absorptivity of the pentose o-toluidine complex. Quantitation of xylose can be made in the presence of a hexose.

Pentoses Used in Cultures of Synechococcus nidulans and Spirulina paracas: Evaluation of Effects in Growth and in Content of Proteins and Carbohydrates [PDF]

Brazilian Archives of Biology and Technology, 2019
The biological assimilation of the sugars present in lignocellulosic residues has gained prominence since these residues are the most abundant and economic residues in nature.

Sequential fractionation and polyoxometalate‐catalyzed oxidation of lignocellulosic biomass improves cellulose purity and formic acid yield

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Lignocellulosic biomass is an important source of renewable chemicals and materials but its full valorization is necessary in order to achieve economic and sustainability goals. This study proposes a two‐step approach for the valorization of lignocellulosic biomass combining solvent‐assisted fractionation and catalytic oxidation with molecular

Innovative strategies for integrating lignocellulosic biomass and microalgae to produce sustainable bioethanol

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study investigated the potential of integrating Parachlorella kessleri biomass with corn stover and tree bark residues as a method for producing bioethanol. The aim was to reduce greenhouse gas emissions, promote environmental sustainability while improving as well food security.

Exploiting agricultural residues for sustainable bioconversion: production of cellulolytic and lignin‐degrading enzymes

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Agroindustrial activity generates substantial waste during harvesting and processing. This study investigated the potential use of sugarcane bagasse, corn cob husk, and wheat bran as substrates for enzyme production by Aspergillus niger and Ceriporiopsis subvermispora. Aspergillus niger and C. subvermispora exhibited comparable filter paperase

Cocoa waste valorization: a review and sustainability analysis of green technologies

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Cocoa residues – notably cocoa pod husks and cocoa bean shells – can be valorized for biocompound recovery, bioenergy production, and waste reduction. This review analyzed 1115 publications related to this field to identify key research trends. Interest is increasing in compounds such as theobromine, bioactive substances, adsorption processes,

Minimizing the enzyme dosage for ethanol production from cellulose‐rich bagasse residues after furfural production

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Through consolidated bioprocessing, cellulosic ethanol production from sugarcane bagasse residues emanating from furfural production (furfural residues, FRs) may offer substantial cost reductions compared with conventional pretreatment–hydrolysis–fermentation of lignocelluloses. Furfural residues have a high enzymatic digestibility and require

Integrating enzyme production and bioenergy recovery through circular bioprocessing of carbohydrate‐rich food wastes into α‐amylase, hydrogen and methane

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study explored the valorization of two carbohydrate rich food wastes, a sugary (spoiled dates, SD) and a starchy (wasted rice, WR) one, for the biotechnological production of α‐amylase, biohydrogen (bioH2), and methane (CH4). Initially, the bioH2 and CH4 production potentials of raw SD and WR were assessed without any pretreatment, via ...
