求翻译：谷氨酸发酵液的pH一般都是在7.0左右，要想得到最大的吸附量，必须加入大量的酸，使其达到谷氨酸的等电点。该提取工艺流程长，产品成本高是什么意思？

The ph of the glutamic acid fermentation broth are generally about 7.0, in order to get the maximum adsorption capacity, must be added to the large amount of acid to the isoelectric point of glutamic acid, etc.. The extraction process, high production costs

The glutamic acid fermentation liquid pH tend to be about 7.0 to get the maximum adsorption capacity, you must join a lot of acid, glutamic acid to the point. The extraction process for high-cost products.

Glutanic acid fermentation fluid pH all is generally about 7.0, must want to obtain the biggest adsorptive capacity, must join the massive acids, enables it to achieve the glutanic acid the isoelectric point.This extraction technical process is long, the product cost is high

Glutamic acid fermentation liquid of pH is around 7, to get the maximum adsorption, must join a lot of acid, isoelectric points bring it to glutamic acid. The extraction process long, high cost of product
