Bacteria that thrive in a low pH, like mutans streptococci and Lactobacillus, begin to dominate.

适宜在低pH值环境中生存的细菌，例如变形链球菌和乳酸杆菌，将会占据主导地位。

Now, normally glycolysis in the cell uses up a lot of phosphate, but this lower pH tends to inhibit glycolysis.

通常细胞内的糖酵解会消耗大量的磷酸盐，但这个较低的pH值往往会抑制糖酵解。

The granules contain molecules that lower the pH of the phagolysosome, making it very acidic, and that kills about 2% of the pathogens.

这些颗粒含有降低吞噬溶酶体pH值的分子，使其呈强酸性，以杀死大约2%的病原体。

And you know what else? While low blood pH does things like change the shape of your hemoglobin to deliver oxygen, high pH causes vasoconstriction.

你知道还会发生什么吗？虽然低血液 pH 值会改变血红蛋白的形状来输送氧气，但高 pH 值会导致血管收缩。

These birds have evolved the lowest gastric pH in the animal kingdom, allowing them to digest diseased carrion and waste without becoming sick.

这些鸟类已经进化出动物界中最低的胃 pH 值，使它们能够消化患病的腐肉和废物而不会生病。

But a study of over 27, 000 men from Finland in 2005 found having a lower urine pH didn't significantly increase the risk of developing bladder cancer.

但是2005 年对 27000 多名芬兰男性的研究发现较低的尿液酸碱值并没有显著增加膀胱癌的风险。

I have really sensitive skin, so I wanted to create a cleanser that had a low pH so it didn't leave my skin feeling stripped or like dry after.

我的皮肤非常敏感，所以我想创造一种 pH 值较低的清洁剂，这样我的皮肤就不会感觉脱皮或感觉干燥。

Even if the seed isn't digested or passed, plants typically need their soil's pH to be between 4.5 and 8, but stomach acid has a much lower pH, ranging from 1.5 to 3.

即使种子没有被消化或传递，植物通常也需要土壤的pH值在4.5到8之间，但胃酸的pH值要低得多，在1.5到3之间。
