  • Bacterial Hydrolysis of Lipids In this lab, students culture two species of bacteria on agar medium that contains an emulsion of plant oils and the dye, sprit blue, which forms a complex with the triglycerides of the oils and gives an opaque blue color to the agar. Colonies of bacteria that can secrete lipase, an enzyme that hydrolyzes triglycerides, develop a light area or “halo” in the surrounding medium, due to the diffusion of lipase into the medium and the resultant breakdown of the oil/spirit blue complex.

  • Bacterial Hydrolysis of Casein In this lab, students culture two bacteria on skim milk agar. The protein casein gives milk its white color. Some bacteria secrete protease enzymes that can hydrolyze casein. When these bacteria are grown on skim milk agar a clear area develops around the colonies, indicating that casein has been hydrolyzed into its component amino acids. View »
  • Hydroponics Using a nutrient-rich water solution and a unique, time-tested approach, you can successfully grow plants with no soil. In a hydroponic system, water does the work. Find out more about this fascinating method and the advantages that make it both appealing and effective. View »
  • Bringing Real-World STEM Experiences to the Classroom by using miniPCR For schools grappling with budget constraints, biotech equipment costs can make it difficult to give students true-to-life learning experiences. One biology teacher has found a new resource that makes real-world instruction more affordable. View »
  • Introduction to Prokaryotes: Bacteria What are bacteria? In this introductory lab students make smears of bacteria on microscope slides from pure cultures, perform a simple stain, and observe their stained slides under a microscope View »
  • Bacteriophages in Human Disease: Friends and Foes Help your students understand the connection between bacteriophages and human disease. This scholarly overview explores how bacteriophages have helped and hindered humans in their quest to overcome certain diseases. Use it as assigned reading or to kick off a classroom discussion.

  • Isolating Bacteria from a Mixture How does a microbiologist isolate bacteria from a sample? In this lab students practice streaking a plate to isolate a single species of bacterium from a known mixture. View »
  • Introduction to Feeding Preferences in Caenorhabditis elegans The nonparasitic soil nematode Caenorhabditis elegans has served as a model organism for research scientists since the 1960s. This lab introduces students to the organism and provides them with the tools necessary to perform simple experiments. View »
  • Coming into the Genome Age Part IV: Detecting Transgenes in Genetically Modified Food Molecular genetic techniques have been used to add transgenes into the genomes of a number of important food plants. View »
  • Biotechnology Transformation Video Use this video to optimize your experience using Carolina's transformation kits. View »
  • Bacteria: The Indole Test In this lab students perform a differential test to distinguish bacteria based on the production of indole. Bacteria are grown on media containing tryptophan and then treated with Kovac’s reagent. If they possess the enzyme tryptophanase, the bacteria can metabolize tryptophan into indole, pyruvic acid, and ammonia. View »
