STAR (STEM Teacher and Researcher) Presentations

As spacecraft are sent to different planets, they take with them microscopic pieces of life from Earth. It is the task of the Biotechnology and Planetary Protection Group to keep as much of this life off other planets as possible as well as document any life that may have been sent. During the construction of the Mars Pathfinder, samples were collected from various locations on the spacecraft to test for contamination. These samples were then isolated, grown, documented, preserved and their 16S rRNA genes were sequenced for identification. The 16S rRNA gene sequence is utilized because it is a highly ...


Characterization Of Bacillus Bacterial Strains; Optimum Growth Temperature, Proteolytic And Lipolytic Activity, Jamie Anne Boring Aug 2013

Characterization of Bacillus bacterial strains is an important step in identifying and removing biofilms contaminating processing equipment. These biofilms lead to large amounts of spores in the final product. Strains that produce spoilage enzymes cause off-flavors, structural defects and reduced shelf life of milk products. Using four treatments, we determined the best growth protocol for each strain to use in future experiments. Treatment 1: 80 o C heat shock and 32 o C 24hr incubation, Treatment 2: 80o C/ 55 o C, Treatment 3: 100 o C/ 32 o C, Treatment 4: 100 o C/ 55 o C. Our ...
