M BiologyHelp, I need to identify a bacteria for my micro bio lab.
We need to try to figure out the genus but don't necessarily need the species. Would be a plus if I could come close to figuring it out. Here are the results of all the tests I performed. Colony morphology Circular, Raised, smooth, glistening Cell morphology Rod, Bacillus (single) Gram stain Pink, Gram - Osmotic sensitivity Up to 20% NaCl Temperature tolerance 4˚ – 37˚ - Mesophile Acidity/alkalinity Prefers Alkaline/neutral Growth on glucose No Growth Growth on amino acids (a.a.) Growth Growth on glucose & a.a. Growth Growth on glucose, a.a. & yeast extract Growth Aerobic/anaerobic Aerobic MacConkey agar No Growth Mannitol salts agar No Growth Amylase No Growth Citrate No Growth Oxidation/fermentation Pink/Orange No Growth Glucose; acid/gas Can’t Produce Acid or Gas From Glucose Methyl red Lt. Yellow, Negative Voges-Proskauer Gold Yellow, Negative Triple iron sugar No Gas, No FeS Indole Does Not Produce Ornithine decarboxylase Positive, decarboxylase of ornithine Nitrate reduction Alot Nitrate Present Oxidase Oxidase Negative Catalase Strong Reaction Coagulase Negative Result, no clot Hemolysis β-Hemolysis Motility Very Motile Thank you for any help!
