Hi, in the first part of this question we need to discuss about the aerobic or aerotolerant organisms that cannot produce the catalase detoxify hydrogen peroxide, hydrogen peroxide.
00:25
So, aerotolerant anaerobes, anaerobes which can survive in the presence of air and partially metabolize oxygen but lack cytochrome systems were discovered to lack the catalase activity but to have the superoxide dismutase activity.
01:16
Now, for the next part it is asking about the what happened to the anaerobes or anaerobic organisms when they are present in on the oxygen or in the presence of the oxygen.
01:38
So, in that case anaerobes are unable to grow in the presence of the oxygen, they must relay on other chemicals as well, other chemicals as the electron acceptors because oxygen is hazardous, hazardous to them and now for the next part so in that case we need to find out the answer regarding the purpose of bacteria that produce the catalase enzyme.
02:31
So, the catalase enzyme, catalase enzyme which is produced by the some bacteria aids in the cellular detoxification, detoxification hydrogen peroxide, hydrogen peroxide bactericidal actions are counteracted by catalase whose presence in the bacteria has linked to the pathogenicity or pathogen, pathogenicity, pathogenicity...
