So i have heard that bacteria release toxins to the media and can retard cell growth, but i don't know how exactly it affect the cells and what changes can occur... is it by changing the pH of the media?? can it cause oxidative stress to the cells?? will that affect the enzymes like gsh, catalase, sod, etc.?? and does the use of antibiotics in media affect the cells?? if so, how and why??
thank you in advance
