Abstract

Aims: To develop a kinetic model for describing the specific effect of pH drop on nisin and pediocin production in whey VSports手机版. .

Methods and results: The effect of pH drop on both bacteriocin productions was tested in non-buffered whey and whey buffered at initial pH 6. 3 with 0. 03, 0. 10 and 0 V体育安卓版. 25 mol l-1 of potassium hydrogen phthalate-NaOH. An accurate description of the experimental data of nisin and pediocin obtained at different pH drops is obtained with the proposed model. .

Conclusions: The proposed model was able to typify both bacteriocins as pH-dependent primary metabolites V体育ios版. .

Significance and impact of the study: The decisive role of pH drop for bacteriocin production on whey was demonstrated and modelled. This study contributes to a better understanding of underlying metabolic regulatory mechanisms, which could facilitate the optimization of bacteriocin production for upscaling. VSports最新版本.
