Blood agar - Study guides, Class notes & Summaries

A bacterial species that cannot tolerate the presence of oxygen and will only grow in the absence of oxygen is classified as a. obligate aerobe b. obligate anaerobe c. facultative aerobe d. mcroaerophile e. aerotolerant anaerobe b A bacterial isolate is subcultured to two blood agar plates, one of which is incubated in an anaerobe jar, and the other is incubated on a shelf in the incubator. After incubation, growth is observed on the plate from the anaerobe jar, but there is no growth on the p...
