Question

Quizplus · Accepted Answer

Enrichment culture is the most efficient method for identifying the major type of bacteria living on the shower curtain and their food source. This method involves growing a specific type of bacteria in a controlled environment with a specific food source, allowing researchers to isolate and identify the specific bacteria present. Direct sequencing may provide information on the type of bacteria present, but not their food source. Producing a molecular phylogeny may help to identify the bacteria present but may not provide information on their specific food source.
