制备

生产菌是枯草杆菌。培养基是脱脂大豆粉（5%）、蔗糖（1.2%）、硫酸铵（0.2%)、碳酸钙（0.2%)等。菌的培养过程可分为菌的发育和抗菌素产生两个阶段。产生杆菌肽时的最适宜温度是37℃左右，而细菌发育期的温度则需略高1-2℃，每分钟的通气量为发酵液量的90%。产生的杆菌肽在pH值为4-5.7的条件下，吸附于羧酸型交换树脂上，然后用弱碱（氨）洗脱。

由地衣形芽孢杆菌（Bacillus licheni formus）发酵而得。以黄豆粉，淀粉、玉米浸出物、糖蜜和无机盐为培养基，接种5%-10%，发酵30-40h。发酵7-8h后，PH从7.3-7.5降至6.06；发酵初期温度控制在30℃左右，经过2-3h温度提高到37℃。发酵结束后用浓盐酸调PH至5.5，然后在20M³发酵液中加入氧化锌50kg，混合30min。然后进行真空，蒸发浓缩，使干物质含量从4.5%-5%提高到17%-20%，再经喷雾干燥得产品。
