Effects of Temperature Lab complete

Overall this lab went quite well. The Bacillus stearothermophilus were not ALL dead. We did have a couple of plates with growth in the 42 degree incubator. However, I have decided NOT to carry this organism over until next semester. It is just too hard to maintain. We also had a couple of plates where Serratia had grown in with other organisms which served as an excellent reminder to my students that they need to really sterilize their inoculating loops before moving into another culture.
