For class data there was four organisms investigated which were: Staphylococcus Aureus‚ Enterococcus hirae‚ Pseudomonas aeruginosa and Escherichia coli. In general the disinfectant didn’t

lactis. My organism did have the catalase enzyme; meaning it was either Bacillus subtilis or Staphylococcus. To distinguish the two‚ I performed the simmons citrate test on them. Since the tube stayed green I confirmed that my organism was Staphylococcus. My organism B could not degrade citrate‚ so that meant my organism was not Bacillus subtilis. In conclusion‚ my unknown organisms were Staphylococcus and Enterobacter aerogenes. REFERENCES Kidane‚ Amine‚ Dr. Microbiology Laboratory Manual. 8th

media turned completely yellow‚ which indicated mannitol was fermented turning the plate acidic. The glucose-bromocresol purple tube appeared completely yellow as well indicating glucose was fermented which turned the agar acidic. The bacteria Staphylococcus aureus was identified because it’s the only gram-positive bacteria‚ which is able to turn both MSA and glucose-bromocrosel tests acidic‚ which gives them their yellow appearance. No further testing was needed to identify the two

in the process of recognizing between the two categories. Streptococcus and Staphylococcus bacteria are responsible for plenty of illnesses and deaths a year. These tiny machines are capable of attacking hosts and making them their most vulnerable. Streptococcus bacteria are often found on the skin‚ inside the mouth‚ or in the respiratory tract and are known to be facultative anaerobes that grow in chains. Staphylococcus‚ on the other hand‚ grow in grape-like clusters. These characteristics are important

Inhibiting concentrations used for all the extracts was 500 mg/ml. Methanolic extract of C. album was found to be most active among all other extracts and inhibits Staphylococcus epidermidis‚ Bacillus subtilis‚ Staphylococcus aureus‚ Escherichia coli. The extract of a mixture of solvents was also found to be effective in inhibiting Staphylococcus aureus. Methanolic extract of C. album was found to give a most clear zone of inhibition. The antibacterial activity is attributed to the phenolic content present

who discovered the first antibiotic. He did this through a rather extraordinary happenstance. While working with the properties of the bacterium staphylococcus he left on vacation. When he got back and was cleaning out his work area he noticed that a few of the slides he’d been working on had been contaminated by fungus. Upon noting that the staphylococcus colonize bordering the fungus had died he began asking more questions. Namely what was it about the fungus that caused it to kill the bacteria?
