- A thin film of moisture on the surface allows the introduced cells to literally spread all overthe surface of the plate.
- If you transfer a loopful of the original culture to a tube of broth and incubate it overnight, you will have a fresh, actively growing, late-log phase culture that will be
- You should transfer a fresh culture to a new slant of agar to make a fresh culture to keep your culture alive until you finish your project.
I'm doing a bio lab where we collected samples from around the school and rubbed it on the sterilized agar plate. The incubator's temperature controls are a little touchy so it is difficult to get it to operate precisely at 37 degrees C. You can improvise by cutting an opening in one side of a cardboard box and doing the work inside.Good luck.Matthew W. How Are Antibodies Used for Blood Typing?

E. Human error includes inaccurately measuring the reactants as well as failing to transfer the entire material to a new container, leading to the loss of product. I then spread it over the surface of the plate, turned it 120 degrees, continued spreading, and then turned it 120 degrees again to spread some more.Incubated the plates at 37 http://nzbsites.com/sources-of/sources-of-error-in-hplc.html coli started to absorb in the initial center area of the agar while I was sterilizing and cooling the spreader.

Therefore, the ethylene produced by these plants could be misleading because some of them were so small they appeared to be dying. If you innoculate a liquid and let it grow overnight with agitation, you should have a nice even suspension to plate.
