Abstract

Objective: Bacterial infections present a significant global health threat, necessitating effective identification for appropriate treatment. Biochemical analysis traditionally classifies bacteria based on metabolic traits. This study aimed to validate biochemical studies on microplates by testing lactose, fructose, glucose, sucrose, and maltose metabolism.


Methods: Biochemical analysis was conducted using microplates to examine bacterial metabolism. Tests for lactose, fructose, glucose, sucrose, and maltose were performed, assessing color changes, turbidity, and pH alterations. The expected color alteration in carbohydrate metabolism was compared between microplate results and experimental tube observations.


Results: Microplate testing revealed unexpected outcomes, failing to demonstrate anticipated color changes during bacterial sugar metabolism. In contrast, experimental tubes exhibited the anticipated yellow color indicative of bacterial fermentation in carbohydrate substrates.


Conclusion: Despite the reliability of biochemical analysis in bacterial classification, microplate testing for carbohydrate metabolism showed inconsistencies. The discrepancy in color alteration between microplates and experimental tubes highlights the need for further validation and refinement of microplate-based biochemical assays in bacterial identification.
