  • Publication number: 20120171739
    Abstract: The present invention relates to an efficient production method of xylitol by using the xylitol producing microorganism introduced with arabinose metabolic pathway to inhibit the production of arabitol, the byproduct, and instead to use arabinose only for cell metabolism in xylose/arabinose mixed medium. More precisely, to express efficiently L-arabinose isomerase (araA), L-ribulokinase (araB) and L-ribulose-5-phosphate 4-epimerase (araD) in Candida tropicalis, codon optimization was performed. Then, each gene was inserted in the gene expression cassette containing the glyceraldehyde-3-phosphate dehydrogenase promoter and the selection marker URA3, which was introduced into Candida sp. microorganism. As a result, arabitol, the byproduct interrupting the purification and crystallization of xylitol could be inhibited, making the production method of xylitol of the present invention more efficient.

  • Patent number: 8211692
    Abstract: The bioconversion of gas feedstreams to liquid products by direct contact with a layer of microorganism obtains enhanced productivity through the regular cycling of liquid across a substrate that supports a biolayer of microorganisms while separating the gas and liquid phases. Such processes produce liquid products such as ethanol, butanol and other chemicals from syngas components by contacting CO or a mixture of CO2 and H2 with a highly porous side of an asymmetric membrane under anaerobic conditions and transferring these components into contact with microorganisms contained within bio-pores of the membrane. A periodic laving of liquid from the liquid contact side to and away from the microorganisms can increase nutrient flow to the microorganisms while enhancing the recovery of liquid products.

  • Patent number: 8198055
    Abstract: Ethanol and other liquid products are produced by contacting syngas components such as CO or a mixture of CO2 and H2 with a surface of a membrane under anaerobic conditions and transferring these components in contact with a biofilm on the opposite side of the membrane. These steps provide a stable system for producing liquid products such as ethanol, butanol and other chemicals. The gas fed on the membrane's gas contact side transports through the membrane to form a biofilm of anaerobic microoganisms that converted the syngas to desired liquid products. A liquid impermeable layer of the membrane assists in establishing direct gas phase contact syngas components with the microorganisms. The system can sustain production with a variety of microorganisms and membrane configurations.

  • Patent number: 8101387
    Abstract: This invention is a process for managing the gas flow through a plurality of bioconversion modules that provide a gas liquid interface. The conversion modules provide the gas liquid interface across an activated surface that converts at least some of the gas components into desired liquid products. Arrangement of the modules and control of gas flow in accordance with this invention enhances the utilization of the gas and the production of desired liquid products by adjusting the flow area to compensate for changes in the volume of the feed gas. Improved control of the gas velocity through the bioconversion modules eliminates problems of liquid condensation and flow maldistribution. The process may sequence the modules to mitigate time variation in microorganism activity and incorporate additional periodic process steps.

  • Publication number: 20120009638
    Abstract: A stable method for producing liquid products such as ethanol, propanol, butanol and other chemicals from syngas components that contacts CO or a mixture of CO2 and H2 with a highly porous side of an asymmetric membrane under anaerobic conditions and transfers these components into contact with microorganisms contained within bio-pores of the membrane. A liquid contacting side of the membrane utilizes a dense layer to control hydration of the bio-pores with a liquid phase. The gas feed directly contacts the microorganisms in the bio-pores and maximizes their utilization of the syngas. Metabolic products produced by the microorganisms leave the membrane through the side opposite the entering syngas. This method establishes a unitary direction across the membrane for the supply of the primary feed source to the microorganisms and the withdrawal of metabolically produced products. The feed and product flow improves productivity and performance of the microorganism and the membrane.
