What is the role of resazurin in fluid thioglycolate medium... - Answer-Resazurin indicates the presence of oxygen in the media 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 not growth on the plate incubated on the incubator shelf. Based on these results how would this organism be categorize...
