最佳碳氮源分别为葡萄糖和牛肉膏。
The best carbon and nitrogen source were glucose and beef extract respectively.
然而，0.1%牛肉膏对产酶具强烈的抑制作用。
But keratinase produced was inhibited largely by 0.1% beef extract.
结果表明，适宜的碳源是葡萄糖、果糖、红糖、乳糖，适宜的氮源是蛋白胨、麦麸、牛肉膏、酵母膏；
The result showed that the optimumcarbon sources were glucose, fructose, brown-sugar, lactose and the nitrogen sources werepeptone, wheat- bran, beef- extract paste, yeast-extract paste.
结果表明：最适宜的碳源是葡萄糖，最适宜的氮源是蛋白胨、麦麸、牛肉膏，最适宜的碳氮比是40：1。
The best carbon source is glucose, and the best nitrogen sources are peptone, beef extract paste and wheat bran. The most favorable ratio of C/N is 40: 1.
单纯用牛肉膏蛋白胨培养基结合平板涂布计数法测定好氧细菌数量，不能真实反映窖内好氧细菌的真实情况。
Moreover, single use of beef extract peptone medium combined with spread plate count method to measure the quantity of aerobic bacteria could not reflect the real status of aerobic bacteria in pits.
肉膏是对肉的高度精炼提取物，通常是从牛肉中提取。它是用来烹调中添加肉的风味，并制作含肉味的汤。
Meat extract is highly concentrated meat stock, usually made from beef. It is used to add meat flavor in cooking, and to make broth for drinking.
