WebbThe maximum growth rate of the E.coli is believed to be found from the exponential curve which yield to µmax = 0.016 h-1. The presence of the second exponential phase is due to the cryptic growth and the possibility … Webb28 feb. 2024 · E. coli MC1061 (obtained from Prof Matti Karp, University of Tampere, Finland) and P. aeruginosa DS10-129 (isolated from soil) 18 were used in all experiments. All cultivations were performed on a shaker at 200 rpm and at 30°C instead of conventional 37°C since some of the tests involved bio-luminescent bacteria. spicer 5-795x specs

Webb4 aug. 2024 · Dilute the starter culture 1:500 to 1:1000 in a large flask with the appropriate volume of media and incubate at 37 °C* for 12 to 16 hours while shaking at 250-300 … WebbThe standard curve analysis of qPCR reactions of each dilution series, a positive E. coli DNA sample with unknown concentration, a no template control and an alternate bacterial species (Figure 5) indicated the unknown sample concentration to be 4.905 ng/ µL through extrapolation of the curve and calculation. WebbTime-kill curve analysis showed OaBac5mini at the concentration of 200 μg/mL (8 × MICs) could effectively kill E. coli ATCC 25922 after co-incubation for 12 h. In addition, OaBac5mini was not hemolytic against rabbit red blood cells and also was not cytotoxic to porcine small intestinal epithelial cells (IPEC-J2). spicer 620200
