Beschreibung
Zusammenfassung:	The invention discloses a bacterial strain and carotenoid production method using said strain, wherein the method comprising the steps of, adjusting grout for the starch raw material with distilled water, sterilizing, adding amylase for liquidation, charging saccharifying enzymes into the fermentation liquor for saccharifying, using the simultaneous saccharifying and fermentation technique to prepare carotenoid through fermentation. The docket number of the cultrue preservation is CCTCC NOM203057. 本发明公开了一种埃菌氏菌属菌种以及采用该菌种生产类胡萝卜素的方法，包括如下步骤：将淀粉质原料用蒸馏水调浆，灭菌，加入淀粉酶液化后，在发酵液中加入糖化酶糖化，同时接入埃菌氏菌属菌种，采用边糖化边发酵技术，发酵生产类胡萝卜素。该菌种的保藏号为：CCTCC NO：M203057。本发明的优点可直接利用玉米、红薯、大米等淀粉质原料发酵生产类胡萝卜素，生产成本低廉、工艺简单。
