Procedure: There were 8 tests used, each test was directed at determining a physiological characteristic of the unknown organism. The tests are as follows: 1. Starch Hydrolysis: starch is a complex molecule consisting of Amylose, a straight chain polymer consisting of 200-300 glucose units. Starch also contains Amylopectin, which is a larger branched polymer containing phosphate groups. In order for bacteria to hydrolyze starch, an enzyme named Amylases will need to be produced. The unknown sample is streaked on a starch plate and after growth occurs, iodine is added to the plate. Iodine turns
