Bacterial Identification of my Unknown Bacterium My unknown number is nine. The differential staining tests conclude that my microorganism is gram-positive and possesses cocci morphology in pairs and chains. The organism tested negative for the presence of catalase. The organism does not ferment lactose. The organism also does not ferment glucose. This is also supported in the selective and differential media tests where the organism has positive growth on TGA, no growth on EMB, positive growth on MSA, and no growth on MAC, therefore it is definitely gram-positive. The unknown bacterium is also positive for the fermentation of mannitol on MSA. This can be further supported by executing fermentation tube tests. SBA: Gamma-hemolytic or lack of change in the medium around colonies: My unknown is … which exhibited biochemical characteristics which genus and species. It is positive for …It also supported the assumed reaction of negative for: glucose fermentation or F tubes 6(glucose, lactose, sucrose, maltose, manose, glycerol) enzymes- amylase, catalase, gelatinase Citrate Urea SIM agar KIA- glucose, lactose, sucrose/sulfur MR/VP MAC/EMB MSA/TGA My unknown bacterium is under the name Streptococcus faecalis according to the lab manual. Since enterococci bacteria are under the genus Streptococcus the conventional and more updated taxonomical name is given as Enterococcus faecalis . E. faecalis , like all other
