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 dry mycelia biomass in Beef peptone media could reach 8.87 mg / mL in 72 h that was 3.56.0 times than the production in other nitrogenous substance media .

牛肉 膏 蛋白 胨是较好的氮源物质，72h干菌丝产量为8.87mg/mL，是其他氮源的3.5~6.0倍。

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%。

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 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。

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 starch beef and soybean peptone and NaCl in the optimum seed culture medium is 1 % 3.0 % and 0.5 % and the microbe number of B12 could reach 34.1 × 10 ~ 9CFU / ml after 24 hours ' fermentation .

最适种子培养基为可溶性淀粉1%， 牛肉浸膏+大豆 蛋白 胨3.0%和NaCl0.5%，培养24h后，B12菌量可以达到34.1×10~9CFU/ml。

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。

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。

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 quantity of the optimized living bacterium was 1.71 times of that of ordinary LB and 1.55 times of that of beef extract peptone under the same conditions .

相同 培养条件下，优化后的 培养 基活菌量分别是普通LB和 牛肉膏 蛋白 胨 培养 基的1.71、1.55倍。
