Correlation analysis of <em>Pediococcus acidilactici</em> 3G3 batch fermentation parameters with bacteriocin production

Abstract

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 <em>Pediococcus</em> <em> acidilactici</em>. The aim of the study was to define the correlation among various growth factors of <em>P.</em> <em>acidilactici</em> 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.
