a Zone of inhibition of AgNPs against Vibrio cholerae 1. (SN–AgNPs, 2. Supernatant, Silver nitrate (AgNO3), GLP–AgNPs). b Microtitre plate demonstrates MIC value (no color change in first 7 wells) using XTT assay. Lane B–D—GLPAgNPS; Lane E–G—SNAgNPs; Lane A and H—LB broth (Blank) c Antibacterial activity of GLP–AgNPs and SN–AgNPs against V. cholerae and MIC values for growth as determined by XTT-reduction assay. d Growth kinetics of V. cholerae in LB (negative control), with GLP and SN alone, with ciprofloxacin (positive control), with GLP–AgNPs and SN–AgNPs at two-fold and four-fold lower concentration than MICs
