An example of using dilutions to do a CFU calculation could go as follows: First, from the initial sample your teacher gives you, you take 1 mL and plate it. The next day you see that there is a lawn of bacteria. This means you cannot count the number of CFU. The next step is m...
To calculate the number of viable cells in the original sample, the number of colonies present after the plates have been incubated is multiplied by the dilution factor. The number of cells in a sample is usually expressed as colony forming units (CFU) per unit of volume (in this case mL...
one can find a countable plate that has between 30-300 colonies on it. Having more than 300 is technically difficult to count, and having fewer than 30 is not statically significant. Using this information, one can calculate both the concentration of bacteria and the number...
While trees vary in shapes and sizes, there is a formula that uses statistical measurements along with a tree’s species to calculate its approximate weight. From the tallest to the oldest, this article explains just how to calculate the weight of a tree and all the factors that go into it...
samples of bacteria that grow in clusters or chains are difficult to disperse and a single colony may represent several cells. Some cells are described as viable but nonculturable and will not form colonies on solid media. For all these reasons, the viable plate count is considered a low estim...
Over time, these small movements lead to large-scale reorganization of the huddle. Moreover, from the high-resolution images is it possible to obtain a precise count of the penguin colony, and to obtain morphometric data from individual penguins to monitor thei...
Calculate the latency (from first bit sent to last bit received) for the following:(a) 10-Mbps Ethernet with a single store-and-forward switch in the path and a packet size of 5000 bits. Assume that Calculate the latency (from first bit sent to last bit received) for:(a) 1-Gbps ...
What does Viable and Non-Viable Spore Count mean to me? This is mostly our opinion and many investigators take a different view, particularly some of our CIH friends. Viable spores mean that the lab counted the number of spores that were alive in the sense that they produced a colony when...
To calculate the maximal antibi- otic dosage, body weight and length, as well as renal and Iiver function, must be known preoperatively. Preoperative imaging of the exact localization of the infection is important for planning the operative procedure. Radiographs may be made in four planes, and...
To win the game, players must contribute the most to the development of the first colony on Mars. This is represented during the game by players gaining Opportunity Points (OP). The player with the most OP at the end of the game is declared the winner. ...
