In what process do bacteria use metabolic capabilities to differentiate species?

• A. Biochemical testing
• B. Genomic sequencing
• C. Microscopic analysis
• D. Cultivation methods

Answer: (A)

Biochemical testing is a crucial method used in bacteriology to differentiate species based on their metabolic capabilities. Each bacterial species exhibits a unique set of biochemical reactions, which can be analyzed through specific tests that assess characteristics such as enzyme activity, fermentation patterns, and utilization of different substrates. For instance, the presence or absence of specific enzymes can reveal whether a bacterium can metabolize certain carbohydrates or produce specific metabolic byproducts, allowing for precise identification and differentiation among closely related species. While genomic sequencing provides detailed genetic information and cultivation methods enable the growth of bacteria under controlled conditions, these approaches do not directly assess the metabolic capabilities that are often key to differentiating species. Microscopic analysis can help identify morphology and structural features but does not evaluate the biochemical characteristics crucial for species identification. Thus, biochemical testing stands out as the primary method for distinguishing bacterial species based on their metabolic functions.
