A bacteria grows optimally at 55o C, pH 9.3 and does not grow in the presence of O2. How should this bacteria be categorized with respect of its temperature, pH, and oxygen requirements?Explanation / Answer
This bacteria can be categorized as Thermophile, alkaliphile and obligate anaerobe.
Thermophiles are bacteria that grow best above 450 C.
Alkaliphiles are bacteria that grow best at alkaline pH.
Obligate anaerobes are bacteria that grow in the absence of oxygen.
