本研究对ＺＬ－９６０１赖氨酸生产菌菌株的形态、培养特性和生理生化特性进行了初步鉴定和分析，并以糖蜜为主要原料，初步确定了该菌的产酸能力。结果表明，该菌为短杆菌（０．８～１．０×１．０～２．５μｍ），需氧，发酵最适温度３０℃，最适ｐＨ７．０～７．２，最适碳源为葡萄糖，最适氮源为硫酸铵；该菌不分解赖氨酸，可耐１５％的赖氨酸，耐３０％的葡萄糖。以糖蜜为主要原料，在最适温度和ｐＨ的条件下，产酸可达６％以上。
In this study, the morphology, culture characteristics and physiological and biochemical characteristics of ZL-9601 lysine-producing strain were preliminarily identified and analyzed, and the ability of acid-producing of the strain was primarily determined by using molasses as the main raw material. The results showed that the strain was Brevibacterium (0.8-1.0 × 1.0-2.5μm), aerobic, the optimum fermentation temperature was 30 ℃, the optimum pH was 7.0-7.2, the optimum carbon source For glucose, the most suitable nitrogen source is ammonium sulfate; the bacteria do not decompose lysine, resistant to lysine 15%, resistant to 30% glucose. To molasses as the main raw material, under the optimum temperature and pH conditions, acid production up to 6%.
