Mannitol salt agar


The purpose of this ecperiemtn was to analyze the salt tolerance of our bacteria. Only bacteria which can tolerate 7.5% salt content will survive and grow on the medium. The salt tolerant gram positive bacteria include Staphylococcus, Micrococcus, and sometimes Enterobacteria. For this experiment we inoculated a mannitol salt agar with our bacteria and let it inoculate for 24 hours. 


Our results turned out to be negative. The bacteria is a non-fermenter of Mannitol.
