An inoculated thioglycolate medium culture tube shows dense growth at the surface and turbidity throughout the rest of the tube. What is your conclusion? The organisms die in the presence of oxygen The organisms are facultative anaerobes The organisms should be grown in an anaerobic chamber The organisms are obligate aerobes

An inoculated thioglycolate medium culture tube is clear throughout the tube except for dense growth at the bottom of the tube. What is your conclusion? a. The organisms are obligate anaerobes. b. The organisms are facultative anaerobes. c. The organisms are aerotolerant. d. The organisms are obligate aerobes.
Indicate whether you would expect growth of the obligate anaerobe to occur under the following circumstances and a brief explanation why: An obligate anaerobe is inoculated into a tube of fluid thioglycolate medium and placed in an incubator. A strictly fermentative aerotolerant anaerobe is co-inoculated into nutrient broth with an obligate anaerobe and placed in an incubator.
