Introduction The purpose of this experiment is to see how much bacteria can and will grow in common places in a typical high school. Common places can mean many things‚ including anything from water fountain spouts to computer keyboards. Such objects can hold up to 2‚700‚000 colony forming units per square inch (or CFU/in sq)(NSF). A colony forming unit is the unit used to find an estimate of the number of cells of a bacteria. This unit of measurement is commonly utilized in the subject of microbiology

Exploring the diversity‚ abundance‚ and variability of diatom-associated bacteria in the oligotrophic ocean I. Abstract The ecology of diatoms may be better explained by conceptualizing them as composite organisms consisting of the host cell and its bacterial associates. Our previous investigated diatom-bacterial interactions at the single-cell level found that bacterial assemblages varied substantially even among closely related individual host cells. The bacterial assemblages associated with single
