现主要经营品种有：动物初级蛋白胨、骨粉、骨块、骨粒、骨油及其他相关产品。
结果表明：牛肝菌母种在葡萄糖蛋白胨培养基基上生长最好，可用此培养基进行乳牛肝菌的液体发酵；
同法，我们确定出最优有机氮源组合为0.5%的酵母膏与1%蛋白胨。
结果表明，有利于侧耳生物量累积和蛋白质合成的最适氮源为蛋白胨，最适碳源为葡萄糖和淀粉。
枯草芽孢杆菌培养液水解鱼蛋白质制备蛋白胨的初步研究
1·The optimum carbon source was glucose and peptone as the optimum nitrogen source.
葡萄糖，蛋白胨是两菌株发酵产酶较好的碳、氮源。
2·However, the effects are not visible adding peptone, coconut milk, aneurin and inositol.
添加蛋白胨、椰子汁、硫胺素和肌醇效果不明显。
