Your unknown bacterial samoe is gram positive produces catalast and produces amylase the most likely identifiacaiton is

Bacillus megaterium

Explanation:

Bacillus megaterium is a bacterium found in diverse habitats. Bacillus megaterium is gram-positive, it means they retain in the thick peptidoglycan cell wall the color of the crystal violet stain. These bacteria produce catalase, which is an enzyme that catalyzes the breakdown of hydrogen peroxide (H2O2) to water and oxygen. Finally, Bacillus megaterium also produces amylase in order to catalyze the hydrolysis of starch into smaller sugar molecules.
