A Inhibitory effect of cLFchimera on biofilm formation which was determined by phenotypic biofilm assay. The absorbance was measured at 590 nm. +cLFchimera: treated with peptide; −cLFchimera: un-treated with peptide. B Inhibitory effect of cLFchimera on DPPH as a free radical. C The results of thermal stability of recombinant chimeric peptide against S. aureus for three different periods of boiling (a, b and c referred to 10, 20 and 40 min, respectively). d: Penicillin (10 mg/disc), −: culture supernatant of L. lactis harboring self-ligated pAMJ1653 vector. * It referred significantly to different levels of peptide concentration. The average percentage of inhibitory effect with different number of asterisk (s) is significantly different based on DUNCAN multiple test (α = 0.05)
