Abstract
การประดิษฐ์นี้เกี่ยวข้องกับ กระบวนการหมักเพื่อผลิตกรดแลคติกไอโซเมอร์ดี หรือเกลือของมัน ซึ่งกระบวนการดังกล่าวประกอบด้วยขั้นตอนของ การเพาะเลี้ยงแบคทีเรียสายพันธุ์สปอโรแลคโต บาซิลลัส เลโวแลคติคัส (Sporolactobacillus laevolacticus) โดยการหมักด้วยนํ้าอ้อยเพื่อให้ได้หัวเชื้อ และการหมักหัวเชื้อที่เตรียมได้ด้วยนํ้าอ้อย โดยที่ขั้นตอนการเพาะเลี้ยงดำเนินการเป็นระยะเวลาที่ทำให้ ความเข้มข้นสุดท้ายของสายพันธุ์สปอโรแลคโตบาซิลลัส เลโวแลคติคัส ในขั้นตอนการเพาะเลี้ยงมีค่า ในช่วง 400 ถึง 1,600 มิลลิกรัมเซลล์แห้งต่อลิตร กระบวนการตามการประดิษฐ์ดังกล่าวสามารถให้อัตรา การผลิตและผลิตผลสูง ได้กรดแลคติกไอโซเมอร์ดีที่มีความบริสุทธเชิงแสงสูง อีกทั้งกระบวนการ ดังกล่าวสามารถทำได้โดยง่าย และลดขั้นตอนที่ยุ่งยาก This invention involves Fermentation process to produce lactic acid isomer D Or its salt Which the process consists of steps of Sporolactobacillus laevolacticus bacteria were cultured by fermentation with sugar cane to obtain the inoculum. And fermentation of the inoculum prepared with sugar cane juice Where the culture is carried out for a period of time The final concentrations of sporolactobacillus levolacticus strains in the culture range ranged from 400 to 1,600 mg dry cells per liter. A process based on such invention can provide rates High productivity and productivity Get lactic acid isomer good with high optical purity. Also the process It can be done easily. And reduce the complicated process
