A Lab Experiment on the Bacteria, Staphylococcus epidermidis
Lab Practical: Staphylococcus epidermidis
can be found in everyday society around the globe. Although one cannot
see them with the naked eyesight, they do exist and also have been around
for an incredible number of years. Some are beneficial, while some cause major
epidemics. For example, Saccharomyces
is a kind of yeast found in bread, beer, and several other food products.
While it could be harmless, other styles of microbes aren't as
forgiving. For instance, Plasmodium
is an associate of the Kingdom Protista and can be the key culprit behind
malaria, a mosquito-borne disease which in turn causes flu-like symptoms and
even death if kept untreated. Probing concerns and labwork help
determine which bacteria are advantageous and which are harmful.
a series of tests, an unknown bacterium had received to each
student to look for the genus in addition to the specifications of the
bacteria. These tests became enough enough in determining
the unidentified bacteria through an activity called differential staining.
Gram staining, produced by Christian Gram helped to differentiate
the bacteria predicated on the existence of some or few layers of
peptidoglycan, one of the key pieces of a bacteria's cell wall structure.
If the bacteria made an appearance purple within the compound microscope,
it had been considered Gram positive as the primary stain, crystal
violet, was absorbed showing the cell contained various layers of
peptidoglycan. Even so, if the specimen made an appearance pink or red, it had been
Gram negative since it absorbed the counterstain, safranin thus
indicating it experienced few layers of peptidoglycan present. Another test
