Homework Answers
1. The organism is fermentative as it contain yellow tube because of low ph
2. The other results are- an oxidizing bacterium and an inert/nonuser(probably pseudomonas, E.coli and alkaligenes fecalis)
3. The organisms that dont use starch grow on a starch agar by breaking down the starch into small sugars, and utilize these small sugars for growth.

Introduction: Selective and differential media are used frequently in Microbiology Pathology Labs to identify a known group of bacteria from a complex mix of other bacteria. The medium is designed to select against as many of the background organisms as possible by using a medium in which they will not grow but the organisms under investigation can grow hence the "Selective" part of the name. Any assayable...
