微生物培養基中(威正翔禹)的氣體溶解度的可用信息。強調的是對氧氣和二氧化碳的溶解度。可以成功地應用于培養基的實驗技術。所有的參數,影響氣體的溶解度,即上述所有媒體的組成進行了深入的探討。在一般情況下,在營養培養基可以通過對數相加的方法預測氣體的溶解度。為此,知識的傳播和溶解度參數(K1)組成的單個化合物是必需的。對于各種遇到的培養液參數K1氧物質可以從文獻數據的評估和總結。提出適當的建議,應用直接和間接的預測方法。失敗的案例也被提及。 英文原文: Available information on gas solubility in microbial culture media is reviewed. Emphasis is given to oxygen and carbon dioxide solubilities. Experimental techniques which can be successfully applied to culture media are presented. All the parameters which affect gas solubilities, i.e., above all the composition of the media are thoroughly discussed. In general, gas solubilities in nutrition and cultivation media can be predicted by a log-additivity approach. To this end knowledge of the composition of the media and the solubility parameters (K1) of the individual compounds is required. For a variety of substances encountered in cultivation broths the parameters K1 for oxygen could be evaluated from literature data and are summarized in this paper. Appropriate recommendations for applying direct and indirect predictive methods are given. Cases of failure are mentioned as well. |
