Copper Experiments 1
Friday, June 22nd
Outline of activity today:
* Met with Jason, who showed us how to make A. ferrooxidans liquid media, prepared Copper 1 and 2 samples (with and without bacteria) and placed on shaker. Will be periodically checked until June 25 twice a day for activity.
* Showed us recipe for solid media, and made enough for two samples, 20 mL (one control with no bacteria). Copper samples were submerged in agarose (see Stevenā€™s pictures). Also learned protocols listed below. Starting Sample masses: {| class="wikitable" style="margin: 1em auto 1em auto;" |+ '''Copper 1: (liquid media only)''' ! scope="col" | Sample ! scope="col" | Mass (g) |- | 1 || 0.0092 |- | 2 || 0.0107. |} {| class="wikitable" style="margin: 1em auto 1em auto;" |+ '''Copper 2: (liquid media only)''' ! scope="col" | Sample ! scope="col" | Mass (g) |- | 1 || 0.1318 |- | 2 || 0.1286. |} {| class="wikitable" style="margin: 1em auto 1em auto;" |+
'''Copper 2: (solid media)'''
! scope="col" | Sample ! scope="col" | Mass (g) |- | 1 || 0.1272 |- | 2 || 0.1282. |} Liquid media and flasks were placed in shaker at 11:35 am, 225 rpm, 30C. Solid media and petri dishes were placed in incubator at 12:42 pm, 30C.
