Enhanced Fumaric Acid Production by Fermentation of Xylose Using a Modified Strain of Rhizopus arrhizus
An enhanced, xylose-utilizing strain of Rhizopus arrhizus was successfully developed via modification using media with increasing concentrations of xylose. Xylose, a relatively cheap monosugar that can be easily obtained from corncobs, rice straw, and vinasse, was the sole carbon source used for both the seed culture phase and the fermentation process. After modification, this newly improved st...
متن کاملProduction of Fumaric Acid by Rhizopus oryzae in Simultaneous Saccharification and Fermentation using Xylo-Oligosaccharides Manufacturing Waste Residue
Production of fumaric acid from xylo-oligosaccharides manufacturing waste residue (XOR) by Rhizopus oryzae CICC 40351 was investigated in a simultaneous saccharification and fermentation (SSF) process. The fermentation conditions for SSF were optimized by an orthogonal design method to maximize the fumaric acid concentration. The highest fumaric acid concentration (12.54 g/L) was reached with a...
متن کاملProtoplast fusion of Rhizopus oryzae and Rhizopus microsporus for enhanced fumaric acid pr
Rhizopus oryzae and Rhizopus microsporus strains were screened for their ability to produce fumaric acid on glycerol as the sole carbon source in the medium. After seven days of stationary culture, fumaric acid was assayed by HPLC analysis, and maximum concentrations of 0.3% (w/v) and 0.33% (w/v) were recorded. Protoplast fusion was used to improve fumaric acid production. A selective medium fo...
متن کاملMicrobial enhance of chitosan production by Rhizopus arrhizus using agroindustrial substrates.
This study investigated the potential of Rhizopus arrhizus UCP 402 for producing chitosan using corn steep liquor and honey as agroindustrial nitrogen and carbon sources. A complete factorial design was used to assess the improved biomass and chitosan production. The results were evaluated using Pareto charts (Statistica 7.0 software). The chitosan obtained was characterized by X-ray diffractio...
متن کاملEnhanced Bioethanol Production in Batch Fermentation by Pervaporation Using a PDMS Membrane Bioreactor
The integration of batch fermentation and membrane-based pervaporation process in a membrane bioreactor (MBR) was studied to enhance bioethanol production compared to conventional batch fermentation operated at optimum condition. For this purpose, a laboratory-scale MBR system was designed and fabricated. Dense hydrophobic Polydimethylsiloxane (PDMS) membrane was used for pervaporation. For fer...
