Study of Environmental and Antimicrobial Agents Impact on Features of Bacterial Growth

摘要

Continuous, real-time observation of bacterial growth has a great advantage for studying the mechanisms of interactions of various compounds with the bacterial cell membrane. With the use of physical methods, which are specific for assessment of continuous changes in turbidity over time, we have shown that bacterial growth was affected by not only on types of antibiotics and phages, but also by their concentration in media. Low concentration of antibiotics and bacteriophages in media has no effect on the bacterial growth process. Our research has shown that if bacterial cell membrane is not completely saturated with antibiotics membrane sensitive sites (MSS), or bacteriophages free unbounded receptors are remained, bacterial growth continues unimpeded.
