Jan 03, 2013 ยท An unknown test tube labeled 120 was given out by the lab instructor. The goal at this point was to determine two separate unknown bacterium, one Gram positive and one Gram negative. The procedures performed consisted of sterile technique in addition to being followed as stated in the referenced course laboratory manual, unless otherwise noted. Algae - Algae - Photosynthesis and light-absorbing pigments: Photosynthesis is the process by which light energy is converted to chemical energy whereby carbon dioxide and water are converted into organic molecules. The process occurs in almost all algae, and in fact much of what is known about photosynthesis was first discovered by studying the green alga Chlorella. Photosynthesis comprises ... On October 22, 2013 an unknown tube numbered 112 was handed out by our lab instructor. The goal is to determine two separate unknown bacterium, one as Gram positive and one as Gram Negative using various differential tests. The procedures and sterile techniques learned throughout the course to identify bacteria were applied to these unknown.
