The rumen inocula taken from cows and sheep were incubated in pH controlled anaerobic batch cultures and the effect of the elevated redox potential (Eh) on metabolism of glucose was examined. In Eh regulated cultures (Eh = +100 mV) the VFA production and production of methane were decreased with a concomitant increase of production of lactate. In these cultures counts of lactilytic bacteria tended to be lower and counts of lactic acid bacteria higher than in cultures with a normal Eh. The elevated Eh also exerted an inhibitory effect on the rumen protozoa. The relevance of these changes to the rumen metabolism is discussed.
从奶牛和绵羊采集的瘤胃接种物在pH值可控的厌氧分批培养中进行培养，并研究了氧化还原电位（Eh）升高对葡萄糖代谢的影响。在Eh调节培养物（Eh = +100 mV）中，挥发性脂肪酸（VFA）的产生和甲烷的产生减少，同时乳酸的产生增加。在这些培养物中，与正常Eh的培养物相比，溶乳酸细菌的数量往往较低，而乳酸菌的数量较高。Eh升高也对瘤胃原虫产生抑制作用。讨论了这些变化与瘤胃代谢的相关性。
