Abstract

The level of CO₂ production and the growth dynamics of the biomass of Rhodococcus erythropolis VKM Ac2017D (Russia) and the yeast strain Saccharomyces cerevisiae OenofermC2 (France) were determined in cultivation media with variously reduced (from 10 to 150 ppm) deuterium concentration. The maximum increase in the rhodococcal biomass was shown in the media with a deuterium concentration of 50 ppm or less. It was noted that the production of CO₂ as an integral indicator of the biological activity of cells is more pronounced in Rhodococcus compared to the yeast. With generally similar dynamics of CO₂ emission curves, prokaryotes showed broader temporal dynamics of its production.

环境同位素组成的修饰对红球菌和酿酒酵母生长和代谢活性的影响

摘要

在氘浓度不同（从10 ppm到150 ppm）的培养基中测定了红球红球菌VKM Ac2017D（俄罗斯）和酵母菌株酿酒酵母OenofermC2（法国）的CO ₂产生水平和生物量的生长动态。在氘浓度为50 ppm或更低的培养基中，杜鹃球菌生物量的最大增加。注意到与酵母相比，在红球菌中CO _2的产生作为细胞生物活性的整体指标更为明显。具有通常相似的CO ₂排放曲线动态，原核生物显示了其生产的更广泛的时间动态。
