A: S.aureus (ATCC 25923); B: E.coli (ATCC 25922); C: Salmonella typhimurium (ATCC 50115); D: Streptococcus mutans (ATCC 25175); CaWH: camel milk whey hydrolysate; CoWH: cow milk whey hydrolysate. a,b,c, means with different superscript letters are statistically different in the same line (p < 0.05); NI: no inhibition. Note: the value regard as mean ± standard deviation or standard error.
