iLab #2 Carbohydrate Tests INTRODUCTION - For this experiment we will be testing four different bacteria with four different tests‚ using glucose‚ lactose‚ and sucrose. Hopefully we will use the information from those test to be able to identify the organisms in each of the samples from the case studies. We will use the results from the four different tests along with the information of how different bacteria react to match up to the case
