对菠菜汁乳酸发酵饮料的生产工艺进行了研究，确定了生产流程及主要工艺参数，生产出色泽纯正、风味优良、质地细腻的乳酸发酵菠菜汁。

The method has the advantages that: the high-concentration substrate inhibition is eliminated and nutritive materials are also supplemented through controlling the pH value in the fermentation environment and supplementing a carbon source and the substrate, so the thalli can grow in the suitable environment, the content of phenyllactic acid reaches 6 to 20g/L after the fermentation, the process is simple, the environmental pollution is less, the operation is convenient, and the output of phenyllactic acid is high.

本发明的优点是：通过控制发酵环境的pH，并补加碳源和底物，既解除了高浓度的底物抑制，又补充了营养物质，使得菌体能够在适宜的环境下生长，发酵结束后，苯乳酸的含量达到6～20g/L，工艺简单、环境污染小、操作方便、苯乳酸的产量高。

The distribution partition of mass metabolic flux of high-level glucose between lactate production pathway and tricarboxylic acid cycle was 90% and 10%, with the ratio of ATP production 20% and 60%, respectively.

结果表明：当葡萄糖浓度较高时，葡萄糖在乳酸生成途径和TCA循环的代谢通量分配比例分别为90%和10%，ATP生成的比例分别为20%和60%，说明葡萄糖大部分经糖酵解途径生成乳酸，而进入TCA循环的少量部分则提供大部分的能量生成。

This willlead to acid productions increment,and intracellular acidifying.

糖酵解过程中必然产生乳酸，如果要维持细胞内的糖酵解状态，乳酸必须被转运出细胞外。

This article is designed to investigate the in vitro biocompatibility of demineralized bone/polylactic acid composite artificial bone.

目的：脱钙骨和聚乳酸都是生物相容性良好的骨替代材料，观察脱钙骨/聚乳酸重组人工骨的体外相容性。

In order to prove the anti-fatigue function, we do the experiment of mouse swimming with a heavy burden, the test of lactic acid, the test of lactic acid deoxidizing enzyme and the test of serum urea nitrogen respectively.

为正实抗疲劳功能，分别作了金匮回生液小鼠负重游泳实验，乳酸的测定，乳酸脱氧酶的测定，血清尿素氮的测定等四个项目试验。

The effects of temperature,time of reaction,amount of catalyst,time of esterifying,time of decompression step by step ,etc, on molecular weight of PLA were studied.

以L-乳酸单体为原料，用逐步减压缩聚法合成了相对高分子量的聚乳酸。

Flow cytometry analysis showed that the 1% and 2% of lactic acid bacteria fermentation filtrates induced the apoptosis of Hela cells at 48 h and 72 h, while the 5% of the filtrate induced the apoptosis at 24 h, 48 h and 72 h, respectively.

流式细胞仪分析，1%、2%的乳酸杆菌DM9811发酵滤液在48、72h可诱导Hela细胞凋亡；5%的乳酸杆菌发酵滤液在24、48和72h均可诱导Hela细胞凋亡。

Optical microscope, electron microscope and FCM were used to analyse the apoptosis of Hela cell treated with different concentration of DM9811 fermentation filtrates. FCM was used to analyse the cell cycle of the differently treated Hela cells.

用光镜、电镜和流式细胞仪分析不同浓度乳酸杆菌DM9811发酵滤液对Hela细胞凋亡的诱导效果；用流式细胞仪分析不同浓度乳酸杆菌DM9811发酵滤液对Hela细胞细胞周期的影响。

Blood from 5 healthy male volunteers was dilutedby 60% using lactated Ringer's solution, 4% modified gelatinsolution, or 6% hydroxyethyl starch 130/0.4, as well as thecombination of lactated Ringer's solution with either of the2 colloid solutions.

取5位健康男性志愿者的血液用乳酸林格氏液、4％的明胶或6％羟乙基淀粉130\0.4，和乳酸林格氏液与这两种胶体液之一的混合物稀释60％。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
