摘要
细菌素的产生通常与细菌生长成正比。 关于细菌素产生的时间和浓度依赖性以及酸性片球菌(Pediococcus acidilactici)的部分氧消耗,缺乏信息。 该研究的目的是确定在分批发酵过程中24小时内P. acidilactici 3G3的各种生长因子与细菌素生产的相关性。 结果证实了细菌素产生与pH降低之间的强烈负相关,但溶解氧与糖消耗之间存在强烈的正相关关系。 此外,通过细菌培养物的细菌培养物的光学密度读数证实活细胞和生物质浓度之间存在强关联。
Bacteriocin production is usually proportional to bacterial growth. There is lack of information with regards to time and concentration dependency of the bacteriocin production, and partial oxygen consumption in Pediococcus acidilactici. The aim of the study was to define the correlation among various growth factors of P. acidilactici 3G3 in relation to bacteriocin production within 24 h of batch fermentation process. The results confirmed a strong negative association between bacteriocin production and reduction in pH, buta strong positive association between dissolve oxygen and sugar consumption. Also, it was confirmed that a strong association existed between live cells and biomass concentration through optical density reading of the bacterial culture with bacteriocin production.
