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. 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。
Expanded graphite were added in PDA medium to observe the growth of Aspergillus niger, and in beef extract peptone medium to observe the growth of Staphylococcus aureus. 向PDA培养基中加入膨胀石墨观察黑曲霉的生长,向牛肉膏蛋白胨培养基中加入膨胀石墨观察金黄色葡萄球菌的生长。
The results showed that the actions of them to the bio wave rhythm circle were also extremely remarkable, and the order was sucrose, beef extract, peptone, yeast extract, agar. 各因子对生物波成环数的影响也都极显著,它们的作用大小依次为:蔗糖,牛肉浸膏,蛋白胨,酵母浸出汁,琼脂。
The suitable seed culture medium was beef extract soya peptone medium; 较适合的种子培养基为牛肉膏大豆蛋白胨培养基;
The optimum liquid medium consisted of 4% konjak powder, 1% each of beef peptone and yeast extract. 产酶最适培养基组成:魔芋粉4%,牛肉蛋白胨和酵母膏各1%。
Among 9 nitrogen sources, protein peptone and beef peptone were better than others. 氮源利用以蛋白胨和牛肉胨最佳。
The optimal ratio in liquid fermentation is 1:1 with 1% maltose as carbon source and 1% beef peptone as nitrogen source. 适宜的氮源为牛肉蛋白胨,浓度为1.0%;碳氮源原料比1∶1。
The cultural medium was studied in this research, the optimum carbon source was beef extract, and the optimum nitrogen source was peptone. 本研究对Ⅶ号菌株的培养基条件进行了探究,结果发现,Ⅶ号菌株的最佳碳源为牛肉膏,最佳氮源为蛋白胨。
