There appears to be some growth over the 4 days; however, the experiments gave drastically different results. Sample 2 almost certainly lost the BC (somewhere in the rinsing procedure?), and the drastic differences between Samples 1 and 3 is unprecedented. It is to be noted that there actually was growth, after all in such a short period of time. Furthermore, the reason that the wax gained mass in sample 2 even without BC is unknown.
