Microbiology: A Systems Approach 4th Edition by Marjorie Kelly Cowan

Exercise 36

Critical thinking is the ability to reason and solve problems using facts and concepts. These questions can be approached from a number of angles and, in most cases, they do not have a single correct answer. A microbe has been found in the boiling hot waters of a deep ocean hydrothermal vent. It cannot be readily stained or cultured in the laboratory, but its rRNA has just been sequenced and analyzed.
A) Make a hypothesis regarding the domain of life to which this microbe most likely belongs.
B) Explain which edition of Bergey's Manual should be used in this case to determine the identity of this microbe.
C) Explain whether the rRNA sequence information is enough to define the species of a microbe.
