    • A method for producing fermentation-based products from corn where the starch has a low gelatinization temperature is provided to be used to produce the fermentation-based products more efficiently with lower energy. The method for producing fermentation-based products from corn comprises a step of mixing a microorganism capable of fermenting a carbon source with the corn to produce fermentation-based products and is characterized in that it uses a corn including a starch having a gelatinization temperature of less than about 60 deg.C. In the method, the corn is derived from a maize plant endosperm of which is homozygous recessive for the allele selected from the group consisting of sugary2, sugary2-waxy, dull-sugary2, dull-sugary2-waxy, amylose extender-dull-waxy, amylose extender-sugary2, and dosage combinations thereof, and the fermentation-based product is selected from the group consisting of ethanol, citric acid, butanol, hydrogen, lactic acid, vitamins, and soluble sugars.

    • PURPOSE: A process for efficiently producing organic acid by continuously fermenting organic acid fermentation microorganisms in a cell recirculation multistage continuous fermenter and recovering organic acid from the culture solution is provided which reduces equipment and production costs and promotes productivity. CONSTITUTION: An organic acid-fermentable microorganism is fermented in a cell recirculation multistage continuous fermenter connected in series a fermenter comprising a fermentation tank, a temperature controller, an agitator and a pH controller, a circulation pump for circulating fermentation mediums from the fermenter to the outside and a cell separator for separating the fermentation mediums and recirculating. The process can be applied to a fermentation process for producing lactic acid, acetic acid, formic acid, citric acid, malic acid, maleic acid, fumaric acid or succinic acid that shows productivity reduction by final products.
    • 目的:提供一种通过在细胞再循环多级连续发酵罐中连续发酵有机酸发酵微生物并从培养液中回收有机酸有效生产有机酸的方法,其降低了设备和生产成本并提高了生产率。 构成:将有机酸可发酵微生物在连续发酵的细胞再循环多级连续发酵罐中发酵,发酵罐包括发酵罐,温度控制器,搅拌器和pH控制器,循环泵,用于将发酵培养基从发酵罐循环到 外部和用于分离发酵培养基并再循环的细胞分离器。 该方法可用于产生乳酸,乙酸,甲酸,柠檬酸,苹果酸,马来酸,富马酸或琥珀酸的发酵方法,其显示最终产物的生产率降低。
