WebThe bacterial growth kinetics following treatment with a TMSB and a TML AgNPs was studied using a protocol that was previously published. 37, 38 Briefly, the susceptible bacterial strains were treated with the following concentrations: 1 × MIC, 1/2 × MIC and 1/4 × MIC of each AgNPs. Ampicillin was used as a positive control at its MIC value. WebDec 1, 2024 · Based on Graph B the exponential growth rate is 0.037 per minute from 120 through 170 minutes, with a lag time of only 100 minutes before entering the log phase. This is the correct plot and the growth rate is correctly expressed a reciprocal time. The fitted equation is ln OD = 0.037 x minutes -7.91.
