  • Patent number: 9663864
    Abstract: Hydrocarbon and hydrogen fuels and other products may be produced by a process employing a combination of fermentation and electrochemical stages. In the process, a biomass contained within a fermentation medium is fermented with an inoculum comprising a mixed culture of microorganisms derived the rumen contents of a rumen-containing animal. This inoculated medium is incubated under anaerobic conditions and for a sufficient time to produce volatile fatty acids. The resultant volatile fatty acids are then subjected to electrolysis under conditions effective to convert said volatile fatty acids to hydrocarbons and hydrogen simultaneously. The process can convert a wide range of biomass materials to a wide range of volatile fatty acid chain lengths and can convert these into a wide range of biobased fuels and biobased products.

  • Publication number: 20150147792
    Abstract: A method of making a C4 diacid from a sugar source by fermentation with a microorganism is described that includes supplementing the fermentation medium with relatively low amounts of betaine. The use of betaine can substantially reduce or even completely eliminate the need for complex nutrient source such as yeast extract, and eliminate a need for vitamins such as biotin, while maintaining a high level of production of the C4 diacid from a simplified sugar based media. The use of betaine improves yield from sugar, final titer, and rate of production per hour. The method is particularly suitable for microorganisms that otherwise display a dependence on yeast extract for high productivity, more particularly for any bacteria, and most particularly for the production of succinic acid from the bacterium Actinobacillus succinogenes. An improved strain of A succinogenes is also described, having a mutation in a betaine transporter that improves C4 diacid production in the presence of betaine.

  • Publication number: 20150104840
    Abstract: The present invention relates to a continuous fermentation process using Actinobacillus succinogenes. It was confirmed that in a cell recycled process, a production amount of succinic acid was about 60 g/L and productivity was about 3.873 g/L per hour. It was confirmed that a cell recycled fermentation process was increased in amount of microbial cells by about 2 times or more, increased in production amount of succinic acid by about 5 times, and increased in productivity of succinic acid by about 8 times or more as compared with the typical continuous culture. Such a succinic acid production process with high productivity and high yield rate can reduce production cost and can also produce succinic acid on an industrial level even at a pilot-scale culture unit without scaling up a culture unit. Therefore, if the process of the present invention is applied, it is expected to be more advantageous for industrial application.

    Abstract: The present invention relates to methods of producing a C4 dicarboxylic acid, comprising: (a) cultivating a filamentous fungal host cell comprising a polynucleotide selected from the group consisting of a heterologous first polynucleotide encoding a C4 dicarboxylic acid transporter, a heterologous second polynucleotide encoding a malate dehydrogenase, and a heterologous third polynucleotide encoding a pyruvate carboxylase; wherein the filamentous fungal host cell is capable of secreting increased levels of the C4 dicarboxylic acid compared to the filamentous fungal host cell without the heterologous polynucleotide when cultivated under the same conditions; and (b) recovering the C4 dicarboxylic acid. The present invention also relates to methods for increasing C4 dicarboxylic acid production, filamentous fungal host cells and malate dehydrogenase variants.

  • Patent number: 8986948
    Abstract: The present invention relates to the use of nucleic acid molecules coding for a bacterial xylose isomerase (XI), preferably coming from Clostridium phytofermentans, for reaction/metabolization, particularly fermentation, of recombinant microorganisms of biomaterial containing xylose, and particularly for the production of bioalcohols, particularly bioethanol, by means of xylose fermenting yeasts. The present invention further relates to cells, particularly eukaryotic cells, which are transformed utilizing a nucleic acid expression construct which codes for a xylose isomerase, wherein the expression of the nucleic acid expression construct imparts to the cells the capability to directly isomerize xylose into xylulose. Said cells are preferably utilized for reaction/metabolization, particularly fermentation, of biomaterial containing xylose, and particularly for the production of bioalcohols, particularly bioethanol.

  • Publication number: 20150072386
    Abstract: To provide a method for producing an organic acid, whereby the desired organic acid can be efficiently recovered without necessity for adjusting the pH to a neutral level in the fermentation step. The method for producing an organic acid, comprises a first step of producing an organic acid by fermentation to obtain a crude liquid containing the organic acid and having a pH of from 1 to 5, and a second step of extracting the organic acid from the crude liquid containing the organic acid obtained in the first step by means of an extraction medium containing a C10-30 diester compound and an alkylamine compound to obtain an extract (1).
