There are only two microorganisms‚ one is Gram positive and one is Gram negative‚ inside the test tube. The Gram positive possibilities are to be narrowed down from Bacillus cereus‚ Clostridium perfringens‚ Corynebacterium xerosis‚ Enterococcus faecalis‚ Streptococcus agalactaie‚ Staphylococcus aureus‚ and

correct. The findings are that we were able to identify‚ by process of elimination‚ the four different test bacteria. PROCEDURE - These procedures were followed for all four media test samples. Label test sample. Record Case study and Gram Stain results. For glucose testing: Select red glucose broth with durem tube. Inoculate red glucose media. Incubate for 24 hours. Record results. For lactose testing: Select red lactose broth. Inoculate red lactose media. Incubate for 24 hours

What color would all bacteria become at the end of the staining procedure if the iodine in the gram step was omitted? What is the role of the alcohol wash in the Gram Stain? What color would all bacteria become at the end of the staining procedure if the alcohol step in the gram stain was omitted

Identifying the Unknown Bacteria: Bacillus cereus Brittany Moy Coastline Community College Abstract Bacillus cereus is a Gram-positive‚ facultative aerobic‚ spore-forming‚ rod-shaped bacterium that is widely distributed among the environment. Introduction The reason for identification of unknown bacteria was to help students recognize different bacteria through different biochemical tests and characteristics. This is important in the medical field because identification of unknown bacteria
