Abstract
การประดิษฐ์นี้เกี่ยวข้องกับวิธีการเพิ่มผลิตภาพ (productivity) ของ L-เมไธโอนิน (L- methionine) และผลิตภาพของกรดอินทรีย์. ที่เฉพาะมากกว่า, การประดิษฐ์นี้เกี่ยวข้องกับ วิธีการซึ่งเกี่ยวข้องกับการเดิมของผสมที่มีเมธิลเมอร์แคพเทน (methyl mercaptan) และได เมธิลซัลไฟด์ (dimethyl sulfide) ที่สัดส่วนที่เหมาะสม สู่ O-อะซีทิล โฮโมวีรีน (O-acetyl homoserine) หรือ O-ซัคซินิล โฮโมซีรีน (O-succinyl homoserine) และสู่เอ็นไซม์ที่มีการออก ฤทธิ์แปลงเมไธโอนินพรีเคอร์เซอร์ไปเป็น L-เมไธโอนิน, เพื่อกระทำปฏิกิริยาเชิงเอ็นไซม์, ด้วย วิธีนี้ ปรับปรุงอัตราการแปลงของ L-เมไธโอนินและกรดอินทรีย์จาก L-เมไธโอนินพรีเคอร์เซอร์, และดังนั้น เพิ่มผลผลิต L-เมไธโอนินเมื่อเปรียบเทียบกับวิธีที่ใช้กันอยู่แล้ว. The invention involves a method of increasing productivity. (productivity) of L-methionine (L-methionine) and the productivity of organic acids. More specifically, this invention involves The method involves the initialization of mixtures containing methyl mercaptan and dimethyl sulfide at the appropriate proportions to O-acetylho. Movirine (O-acetyl homoserine) or O-succinyl homoserine (O-succinyl homoserine) and to the enzyme released. The effect of converting methionin pre-cursor to L-methionin, to act on enzymatic reactions, in this way improve the conversion rate of L-methionin and organic acids from L-methionin preliminary cursors, and therefore increase L-methionin yield compared to already used methods.
