Interactions based on alpha diversity metrics via ANOVA, where the effect of treatment (peptide modifications: Intact casein, enzyme hydrolysate, and acid hydrolysate and <i>Campylobacter jejuni</i> inoculation) was assessed on microbial diversity based on time (0, 24, and 48 h).

Shannon’s entropy was utilized to assess richness of microbial composition and Pielou’s Evenness was used to describe homogeneity of microbial community. Significance was determined at P < 0.05. *Sums of Squares. *Projected Residuals: Fit values for metric vs. observation error (residuals). Residuals represent the difference between any data point and the regression line. (XLSX)本研究采用香农熵（Shannon’s entropy）评估微生物群落组成的丰富度，以皮卢均匀度（Pielou’s Evenness）表征微生物群落的均匀性。显著性判定标准设定为P < 0.05。*平方和（Sums of Squares）。*投影残差：指标拟合值与观测误差（残差）的对应关系。残差指任意数据点与回归直线之间的差值。(XLSX)
