BIOB12H3 Lecture Notes - Evolutionary Arms Race, Time Point, Exponential Growth
Document Summary
Biob12h3s: cell & molecular biology laboratory. Bacteria are simple prokaryotic cells, which include many different types and species. Of course most live in more pleasant environments, such as the human digestive system. We will leave a formal description of bacterial cell metabolism and diversity to the microbiology course. These techniques will then be expanded in upper level courses in biology. Many strains of e. coli can grow on a carbon source (like glucose) in simple inorganic salts. Of course if the medium is more complete, growth is facilitated. Typically, e. coli is grown in a medium known as lb (luria broth or. Other factors that are important for growth are oxygen (for complete respiration to occur) and temperature. The culture can be oxygenated by rapid shaking in an incubator, and for e. coli, the optimal growth temperature is. Under these conditions e. coli can reproduce in about 20 minutes.
