一、概述溶解氧是发酵生产的一个重要参数,发酵液中溶解氧的含量直接影响到发酵产品的产量,如果溶解氧低于需要量,使微生物处于缺氧状态,就会影响它的生长,造成代谢异常,使产品的产量下降。相反,若因通风量过大,使溶解氧高于需要量,则不仅意味着增加动力消耗,而且对于某些产品来说,也会影响微生物的生长,使产品的产量下降。因此测量和控制溶解氧,使其保持最合适的浓度,对于控制发酵过程,提高产量,保证质量,节省动力,降低成本,提高经济效益,具有重要意义。YQ-W-1型发酵罐溶解氧测定仪,通过
I. Overview Dissolved oxygen is an important parameter in fermentation production. The content of dissolved oxygen in fermentation broth directly affects the yield of fermentation products. If the dissolved oxygen is lower than the requirement, the microorganisms will be in anoxic state, which will affect its growth. Cause metabolic abnormalities, so that the decline in product output. Conversely, if the ventilation is too large, higher than the required amount of dissolved oxygen, not only means increasing power consumption, but also for some products, will also affect the growth of microorganisms, the product yield decline. Therefore, measurement and control of dissolved oxygen, to maintain the most appropriate concentration, for the control of the fermentation process, increase production, ensure quality, save energy, reduce costs, improve economic efficiency, is of great significance.
