Highly effective against obligate aerobes
WebBased on the location and distribution of the bacteria in these tubes, a species can be classified as obligate aerobe, microaerophile, facultative anaerobe, aerotolerant anaerobe, or obligate anaerobe. Figure 2: Microbial oxygen requirements can be determined using thioglycollate agar tubes. The green dots in this diagram represent bacterial ... The oxygen sensitivity of obligate anaerobes has been attributed to a combination of factors including oxidative stress and enzyme production. Oxygen can also damage obligate anaerobes in ways not involving oxidative stress. Because molecular oxygen contains two unpaired electrons in the highest occupied molecular orbital, it is readily reduced to superoxide (O 2) and hydrogen peroxide (H 2O 2) within cells. A rea…

Webobligate aerobe Definition. Organisms that need oxygen for their growth are called obligate aerobes. With cellular respiration, these organisms utilize oxygen to metabolize compounds such as sugars, fats and obtain energy from them. Mycobacterium tuberculosis and Nocardiaasteroides are an example of obligate aerobes.
