About This Lesson
Students collect samples that they predict will contain communities of cellulose-degrading microbes and test for the ability of microrganisms in their samples to break down pure cellulose (filter paper). In the process, groups collect evidence to test predictions about which environmental microbial samples will be the most effective for degrading cellulose. By comparing results across groups, students can begin to uncover patterns and develop explanations about the types of environments that support cellulose-degrading microbes. This lab method is nearly identical to that used by GLBRC researchers and student results could help scientists discover new enzymes for efficient biofuel production.
