Solved in 2 steps
- Why are endospore forming bacteria commonly found in soil?What is the oxygen requirement of this microbe? Thioglycollate Broth -Obligate aerobe=growth only occur at the top band of the broth -Facultative anaerobes= growth uniformly throughout the broth -Obligate anaerobes= growth only at the bottom of the tube -Aerotolerant= growth throughout the tube until just below the surface of the broth -Microaerophiles= growth in a heavy band just below the surface of the brothWhy do petroleum-degrading bacteria need to attach to thesurface of oil droplets?
- Why is nutrient broth considered as a universal growth medium for bacteria?How would a facultative anaerobe growth curve change if it was placed in the presence of oxygen environment? If the organism were to be placed in an anaerobic environment during log phase, how would the growth curve look?Bacteria that prefer to grow at room temperature at low pH are: Mesophilic acidophiles Microaerophilic alkalophiles Psycrophilic neutraphiles Thermophilic acidophiles
