Today at the lab I helped a fellow intern by making a two liter solution of "food" for something called the "Biohydrogenator." While I am not sure what it does, I am sure it is important, as it has been sitting on the lab bench ever since I started. In order to create the solution, I had to use an anaerobic glove box (fancy) to extract Na2S and FeCl2 from special bottles and put them into the mixture. I also weighed out different amounts of potassium acetate, potassium phosphate, ammonium chloride, and sodium phosphate (thanks to Pete for teaching me how to do that) and add it to the mixture.
