BIOS 242 Week 4 iLab: Carbohydrate Tests Introduction: The purpose of this lab was to determine which carbohydrates a bacterium can use on three different specimens. The acid from glucose test is done to see if the microbe can ferment the glucose a carbon source. The lactose fermentation test was performed to see if the microbe can ferment lactose as a carbon source and the sucrose fermentation test was performed to see if the microbe can ferment sucrose as a carbon source. I tested each of t...
