The influence of power consumption on oxygen transfer during non-Newtonian and surfactant-producing microbial fermentations has been scarcely reported. In this work, we study the oxygen transfer and bubble size distributions in a real 100 L fermentation (producing poly(γ-glutamic acid)) occurring under constant stirring speed (N) and under constant retrofitted power drawn (Pg/V).

在两种功率消耗方案下,用于生产聚(γ-谷氨酸)的贝莱兹芽孢杆菌 83 中试规模培养中发生的氧气转移和气泡大小

几乎没有报道在非牛顿和产生表面活性剂的微生物发酵过程中功耗对氧气传递的影响。在这项工作中,我们研究了在恒定搅拌速度 ( N ) 和恒定改造功率 ( Pg / V ) 下发生的真正 100 L 发酵(生产聚(γ-谷氨酸))中的氧气转移和气泡大小分布。
