查询词典 lactate

In the current study, anoxic dechlorinations of p, p'-DDT,γ-HCH, HCB in the Liao River sediment were studied under the following conditions: without any additional short chain carbon substrates or vitamin B〓; with the addition of short chain carbon sources (including sodium lactate, sodium propionate or sodium acetate); with the addition of vitamin B〓; with the addition of both short chain carbon substrates and vitamin B〓, with the addition of sodium dodecyl sulfate , a kind of surfactant; the coexistence of the three chlorinated compounds.

氯代有机物一般都是典型的持久性环境污染物，其中部分氯代有机物还是环境激素类物质，例如，滴滴涕、林丹和六氯苯等，这些氯代有机物在环境中的迁移转化一直是国际环境化学领域的热点、重点课题。氯代有机物进入环境水体后，成为沉积物吸附态有机污染物的重要成分，天然水沉积物经常处于缺氧状态。因此，研究氯代有机物在天然水体沉积物中的缺氧脱氯行为是非常必要的。

With the existence of additional carbon sources, sodium lactate, sodium propionate or sodium acetate, the faster pH rised, the faster p, p'-DDT dechlorinated, which indicate that the existence of short chain organic substrate supplies sufficient electron donors for the dechlorination process, and p, p'-DDT can obtain electrons more easily during the stage of pH rising.

并且由于p，p'-DDT的还原脱氯与细胞色素氧化酶及辅基FAD有关，外加碳源下p，p'-DDT的缺氧降解多数发生在体系pH值上升的阶段，且pH值上升较快时对应的p，p'-DDT缺氧降解较快，而在无外加碳源的体系中，由于可供p，p'-DDT还原脱氯的电子量限制了p，p'-DDT还原脱氯的速度，未发现上述现象。

In the current study, anoxic dechlorinations of p, p'-DDT,γ-HCH, HCB in the Liao River sediment were studied under the following conditions: without any additional short chain carbon substrates or vitamin B〓; with the addition of short chain carbon sources (including sodium lactate, sodium propionate or sodium acetate); with the addition of vitamin B〓; with the addition of both short chain carbon substrates and vitamin B〓, with the addition of sodium dodecyl sulfate , a kind of surfactant; the coexistence of the three chlorinated compounds.

本文分别采用不外加碳源和维生素B〓外加碳源（包括乳酸钠、丙酸钠或乙酸钠）、外加维生素B〓以及同时外加碳源和维生素B〓的方法，考察了p，p'-DDT、γ-HCH和HCB三种氯代有机污染物单独或混合存在下，在辽河沉积物中缺氧脱氯降解的情况，主要得到以下结论

The pH, acetic acid, propanoic acid and VFAs were detected, in Selenomonas ruminantium culture fluid at Oh, 6h, 12 h, 24 h, 36 h, after adding yeast. The results indicated that lactate uptake can be stimulated by all of the six yeast strains at all of six concentrations levels.
