抗菌素对细菌细胞利用丙酮酸盐的影响研究得还不多。本文根据实验结果说明左旋霉素、链霉素、土霉素、金霉素、和青霉素对大肠桿菌静息细胞在环境通气不足的条件下消耗丙酮酸盐的影响。静息细胞的制备是把大肠桿菌接种在普遍琼脂培养基上培养18—20小时,用生理盐水洗下并洗涤三次后低温保存备用。丙酮酸盐的浓度用光电比色法测定。实验结果 The impact of antibiotics on the use of pyruvate by bacterial cells is not much studied. This article based on experimental results show that levomycin, streptomycin, oxytetracycline, chlortetracycline, and penicillin Escherichia coli resting cells in the absence of environmental hypoglycemic consumption of pyruvate. Resting cells were prepared by inoculation of E. coli on a common agar medium for 18-20 hours, washed with saline and washed three times and stored at low temperature for later use. The pyruvate concentration was determined by photoelectric colorimetry. Experimental results
