  • Publication number: 20130171705
    Abstract: L-Lactic acid fermentation using non-edible biomass requires a lactic acid bacterium suitable for fermentation using a mixture comprising oligosaccharides or mixed saccharides produced by enzymatic treatment of cellulose and hemicellulose, so that simultaneous saccharification and fermentation are enabled. Further, it must be taken into consideration that use of pentoses such as xylose derived form non-edible biomass as the raw material provides lactic acid as well as equimolar acetic acid, which halves the molar yield of lactic acid, and high concentration L-lactic acid induces fermentation inhibition, which makes it difficult to produce L-lactic acid at high yield. The present invention provides a novel lactic acid bacterium that can solve these problems. With the lactic acid bacterium of the present invention, L-lactic acid showing a high optical purity of 99.

  • Publication number: 20130157329
    Abstract: A system (100, 200) is described for correcting constant volume acidity of fermentative media for the production of organic acids, which comprises a fermenter (1) provided with a pH sensor (P1) a filtration module (2) provided with a filtering element, an addition vessel (3) provided with a main metering element (4), and a heat exchanger (5). Operation of the system (100, 200) is controlled by a controller (CT). As soon as the sensor (P1) detects a reduction in pH to below the ideal values for producing organic acid, the controller (CT) calculates the amount of fermentative medium to be withdrawn from the fermenter (1) and said amount is conveyed to the vessel (3) in order to be alkalinized and returned to the system. Arrangements of the system with more than one fermenter are also described. The process for correcting acidity used by the system (100, 200) of the invention is likewise described.

  • Publication number: 20130040350
    Abstract: A dense but oxygen permeable membrane separates the oxygen supply compartment from the fermentation compartment, which contains all microorganisms, a nutrient medium and the pretreated lignocellulose. The oxygen, necessary for the growth and the activity of the aerobic cellulolytic enzymes producing microorganisms is solely transported from the oxygen supply compartment through the membrane, which leads to an oxygen gradient within the biofilm growing on the membrane. The oxygen rich zone of the biofilm lies on the membrane whereas the biofilm further away from the membrane as well as the surrounding nutrient medium are oxygen depleted. In the aerobic biofilm the extra-cellular enzymes are produced in situ and are released into the nutrient medium where they hydrolyse the cellulose and hemicellulose into soluble monosugars, which are then converted to the desired fermentation product by suitable microorganisms in the anaerobic zones of the reactor.

  • Publication number: 20130029389
    Abstract: The present invention provides a method for producing D-type lactic acid by using E. coli and glucose derived from a plant as active ingredient, in which D-type lactic acid is a raw material of D-type polylactic acid in order to produce a stereo-complex polylactic acid blend which is a valuable material as the plant-based material for the manufacture of interior and exterior parts of an automobile. More specifically, the present invention relates to a bacterial strain and a fermentation process for producing D-type lactic acid with high optical purity.

  • Publication number: 20130011886
    Abstract: The present invention comprises pretreating a lignocellulosic feedstock with acid at a pH between about 2.0 and about 3.5 to produce a composition comprising an acid pretreated feedstock. The acid pretreated feedstock is then enzymatically hydrolyzed with cellulases and ?-glucosidase. The glucose is fermented by microorganisms to produce a fermentation broth comprising the fermentation product, followed by recovery of the fermentation product. The steps of enzymatically hydrolyzing and fermenting are conducted at a pH below about 4.0.

  • Publication number: 20130011885
    Abstract: Methods are provided for the efficient fractionation of lignocellulosic biomasses into cellulosic, hemicellulosic and lignin fractions, wherein concentrated organic acid vapors are applied to the biomass at elevated temperatures at the location(s) or near the location(s) where the biomass has been harvested and gathered, to at least partly depolymerize or substantially solubilize the hemicelluloses and lignins in the biomass. The organic acid-treated biomass is in either case then dried and pelletized for extended bulk storage and/or for shipment to a second facility some distance away. The organic acid-treated biomass may be processed into desired chemicals, fuels and/or fuel additives at the local processing site or at a second facility away from the local processing site, or the pelletized material may be used as a ruminant feed locally or at a feedlot some distance removed from the local processing site.
