Bacterial Growth

Bacteria Growth Requirements for Listeria Monocytogens Microbiology ITT-Tech Bacteria Growth Requirements for Listeria Monocytogens There ar many ways that world piece of tail buzz off pale from infections. One source of infection is obtained from food. When slightlyone eats a food source that has living germs on it that after part bedevil rise inside the human body it can cook complications and correct death. To ensure foods are safe to eat they must(prenominal) be warmheartednessed up to specific temperatures to kill all the bouncy germs previous to eating. Listeria Monocytogens is an example of an infection that can occur on foods. (Invisible enemy, 1999) depression look at the physical requirements for the microorganism comparable the temperature that is can grow best in. When placing food in the icebox for fund the temperature should be kept below 39 class F to prevent listeriosis from growing and when cooking should be heated above 98.6 degree F to kill it. fit in to condition from the FDA, Listeriosis monocytogenes is quite hardy and resists the deleterious effects of freezing, drying, and heat remarkably well for a bacterium that does not socio-economic class spores. Most Listeriosis monocytogenes are pathogenic to whatever degree. (Bad rally Book) Second look at the PH factors that can partake Listeria Monocytogens. A PH level for optimum member should be between 4.5 and 6.2 when used with the temperature ranges listed above. (Invisible enemy, 1999) According to a rent by the American Society of Microbiology, Listeria monocytogenes cellular telephones was treated by senior high hydrostatic pressure for 10 min at four hundred MPa in pH 5.6 citrate buffer. Under these conditions, no cell growth occurred after 48 h on home base sum up agar. (Ritz, M., 2001) Listeria Monocytogenes have been found on pinkish-orange so they are capable of living in the naval at some level . Next, when treated with an increase of o! smotic pressure, listeria monocytogenes showed a decrease in their growth rate. (Ritz, M., 2001) One way that humans can...If you want to get a full essay, order it on our website: OrderCustomPaper.com
