Biochemical Tests Virtual Laboratory

Perform biochemical identification tests on an unknown bacterial culture using realistic laboratory procedures.

Each test uses fresh materials and a separate test tube where required. Complete the physical procedure, observe the reaction, and interpret the result.

The unknown organism is intentionally hidden until the final identification stage.
