Figure 1. Silver resistance of B. megaterium IBBPo17. (a) Silver streak plate assay (AgSA): cultures grown onto LB agar (control); LB with 0.1 mM AgNO3 (Ag+). Petri plates visualized under visible and UV light. (b) Silver agar diffusion assay (AgDA): discs impregnated in 0.1–100 mM AgNO3 (1–6) or spots of each AgNO3 solution placed or dropped on the LB agar surface, 0.1 mM (1), 1 mM (2), 10 mM (3), 50 mM (4), 75 mM (5), 100 mM (6). (c) Silver 48-well microtiter plate assay (AgMA): cultures grown in liquid LB (control, 1); LB with 0.1–1 mM AgNO3 (2–7), 0.1 mM (2), 0.15 mM (3), 0.2 mM (4), 0.25 mM (5), 0.5 mM (6), 1 mM (7); uninoculated LB (negative control, nC); cell viability by TTC assay (CVTA), each well was added with 0.3% TTC. (d) Cell viability by spot assay (CVSA): cultures grown in liquid LB (control, 1); LB with 0.1–1 mM AgNO3 (2–7), 0.1 mM (2), 0.15 mM (3), 0.2 mM (4), 0.25 mM (5), 0.5 mM (6), 1 mM (7). Cell growth by determining OD660: the values represent the average from two independent assays with standard deviation (nm + SD).

Figure 4. Antibacterial activity of the AgNPs synthesised using biomass and culture supernatant of B. megaterium IBBPo17. (a)–(d) Antibacterial activity (Aa) of AgNPs against Gram-positive (AaGP) and Gram-negative (AaGN) bacteria. AgNPs synthesised by cultures grown in liquid LB with or without organic solvents: control (1, 6), cyclohexane (2, 7), n-hexane (3, 8), n-decane (4, 9), n-hexadecane (5, 10); AgNPs synthesised using biomass (intracellularly synthesised, IcS, 1–5) and culture supernatant (extracellularly synthesised, EcS, 6–10). Inhibition zone (mm): the values represent the average from two independent assays.
