Fundamentals Of Microbiology 10th Edition by Jeffrey Pommerville

Exercise 19

Answer the following questions that pertain to (1) transcription and translation, and (2) mutations. Use the genetic code (Table). Bioremediation is a process that uses bacteria to degrade environmental pollutants. You want to use one of these organisms to clean up a toxic waste site (biochemical refinery) that contains benzene in the soil around the refinery. Benzene (molecular formula C 6 H 6 ) is a major contaminant found around many of these chemical refineries. You have a culture of bacterial cells growing on a culture plate that were derived from a soil sample from the refinery area. You also have a supply of benzene. Explain how you could visually identify chemoheterotrophic bacterial colonies on agar that use benzene as their sole carbon and energy source for metabolism.
