The development of bacterial cellulose (BC) industrialization has been seriously affected by its production. Mannose/mannan is an essential component in many biomass resources, but Komagataeibacter xylinus uses mannose ineffective way, resulting waste. aim this study was to construct recombinant bacteria use mannose-rich efficiently as alternative and inexpensive carbon source place the more commonly used glucose. This strategy aimed at modification catabolic pathway via genetic engineering...
The effects of the redox environment on acidic hydrothermal pretreatment were investigated in experiments with sugarcane bagasse (190 °C, 14 min) and Norway spruce (205 5 min). To modulate environment, was performed without gas addition, N2, or O2. Analyses covered pretreated solids, liquids, condensates, enzymatic digestibility, inhibitory liquids yeast. Addition gas, especially O2, resulted increased severity, as reflected by up to 18 percent units lower recoveries 31 glucan recoveries,...
Hydrothermal pretreatment improves bioconversion of lignocellulose, but the effects different acid catalysts are poorly understood. The sulfuric (SA) and sulfur dioxide (SD) in continuous steam wood Norway spruce were compared temperature range 195°C-215°C. inhibitory liquid on cellulolytic enzymes Saccharomyces cerevisiae yeast higher for SD- than SA-pretreated material, increased with increasing temperature. However, susceptibility to pretreated SD was 2.0-2.9 times that SA at same Data...
Komagataeibacter xylinus ATCC 23770 was statically cultivated in eight culture media based on different carbon sources, viz. seven biomass-derived sugars and one sugar mixture. The productivity quality of the bacterial nanocellulose (BNC) produced were compared. Highest volumetric productivity, yield consumed sugar, viscometric degree polymerization (DPv , 4350-4400) thermal stability achieved using glucose or maltose. Growth xylose, mannose galactose resulted lower DPv but larger fibril...
, is a widely used medicinal fungus. The polyphenols extracted from this fungus exert antioxidant, anti-inflammatory, and hypoglycemic effects. In study, the fruiting bodies of
Abstract BACKGROUND More extensive utilization of bacterial nanocellulose (BNC) is severely restricted by the low efficiency and small scale traditional static cultivation. Submerged fermentation in stirred‐tank reactors (STRs) potentially favourable for large‐scale production BNC, but scale‐up cultivation remains challenging. Even though STR most commonly used submerged industry, there are few previous attempts to BNC pilot using an STR. Furthermore, question how affects properties has...
Utilization of bacterial nanocellulose (BNC) for large-scale applications is restricted by low productivity in static cultures and the high cost medium. Fiber sludge, a waste stream from pulp paper mills, was enzymatically hydrolyzed to sugar, which used production BNC submerged cultivation Komagataeibacter xylinus. Compared with synthetic glucose-based medium, purified fiber sludge hydrolysate using shake-flasks enhanced 0.11 0.17 g/(L × d), although average viscometric degree...
Yeast transcription factors (TFs) involved in the regulation of multidrug resistance (MDR) were investigated experiments with deletion mutants, transformants overexpressing synthetic genes encoding TFs, and toxic concentrations lignocellulose-derived substances added to cultures as complex mixtures or specific compounds, viz. coniferyl aldehyde, 5-hydroxymethylfurfural, furfural. In presence from spruce wood, YAP1 STB5, TFs oxidative stress response, exhibited enhanced relative growth rates...
Abstract Background Bacterial nanocellulose (BNC), a natural polymer material, gained significant popularity among researchers and industry. It has great potential in areas, such as textile manufacturing, fiber-based paper, packaging products, food industry, biomedical materials, advanced functional bionanocomposites. The main current fermentation methods for BNC involved static culture, the agitated culture had lower raw material conversion rates resulted non-uniform product formation....
Through pretreatment and enzymatic saccharification lignocellulosic biomass has great potential as a low-cost feedstock for production of bacterial nanocellulose (BNC), high value-added microbial product, but inhibitors formed during remain challenging. In this study, the tolerance to lignocellulose-derived three new BNC-producing strains were compared that Komagataeibacter xylinus ATCC 23770. Inhibitors studied included furan aldehydes (furfural 5-hydroxymethylfurfural) phenolic compounds...
This study evaluated the co-production of pigment and bacterial nanocellulose (BNC) from S. salsa biomass. The extraction beet red reduced salts flavonoids contents by 82.7%–100%, promoting efficiencies enzymatic saccharification biomass fermentation BNC hydrolysate. SEM analysis revealed that process disrupted lignocellulosic fiber structure, chemical lessened cellulase inhibitors, consequently facilitating for 10.4 times. producing strains were found to be hyper-sensitive NaCl stress,...
Fruit juice industry generates a large amount of wastewater, which contains substantial waste activated carbon for turbidity removal. Due to the low concentrations useful compounds in cost extraction is extremely high. Two new bacterial nanocellulose (BNC) producing strains were isolated and identified. These produced 6.11 1.38 folds BNC from pear wastewater than conventional medium, respectively. spontaneously encapsulated suspended particles during fermentation, flocculating collecting...
