7/22: Culture Duration (4 days)

Monday, 7/22/2019
Objectives
Measure the amount of cellulose present in the 4 day culture tube.
Protocols
Significant Notes
This section should list any notes of changes in the Protocols and other notes of interest.
Use 25 mL NaOH in Step 4 (in the original protocol it does say 25 -eric)
Wait only 1.5 hours in Step 4
Step 4 water bath incubation started at 3:19 PM.
Observations and Issues
This section should note any observations and issues with running your experiments.
The experiment 2 tube appeared to be missing right before the overnight incubation (air-dry)
It could possibly have slipped through during one of the rinse stages, for it was exceptionally clear
Expected Results
We expect there to be some mass of BC, roughly equal in all trials
Results
Protocol 1
Conclusion
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.
