Differential and Biochemical Tests to Identify Pathogens

Microbiologists focus on metabolic capabilities and biochemical reactions to determine the type of microorganisms thriving on various surfaces. Whereas some biochemical tests are run independently following the preparation of sample culture, others are integrated into the differential growth media. Differential and biochemical tests allow for the examination of various microorganisms’ properties such as nutrient requirement, metabolism, susceptibility to antibacterial agents and presence of hydrolytic enzymes.
