More Growing

Tuesday, September 3, 2013

Today in lab we looked at our cultures that we collected the previous Thursday. Our sample from the river rock grew a lot of tan and bright orange bacteria. 

We proceeded to take a sample of the culture and spread it into a new dish. This allowed for a pure sample to be collected. We spread the bacteria in each quadrant of the dish, and sterilized the hook after each spread.

After this was completed we labeled our sample and put it in the incubator. We stored it at air temperature. Today we also looked at the bacteria under the microscope and took pictures of the bacteria.

Afterwards, we put our old samples into the refrigerator to preserve our bacteria. We then proceeded to discuss Canvas. That’s all for now!
