Bacterial Growth

Bacteria Growth Requirements for Listeria Monocytogens Microbiology ITT-Tech Bacteria Growth Requirements for Listeria Monocytogens There ar many ways that valet piece of tail pop out pale from infections. One source of infection is obtained from food. When slightlyone eats a food source that has living germs on it that back end bless rise inside the human body it can scram complications and correct death. To ensure foods are safe to eat they must(prenominal) be warmheartednessed up to specific temperatures to kill all the decease 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 standardized the temperature that is can grow best in. When placing food in the refrigerator for fund the temperature should be kept below 39 compass point F to prevent listeriosis from growing and when co oking should be heated above 98.6 degree F to kill it. check to condition from the FDA, Listeriosis monocytogenes is quite hardy and resists the deleterious personal effects of freezing, drying, and heat remarkably well for a bacterium that does non socio-economic class spores. Most Listeriosis monocytogenes are pathogenic to some degree. (Bad rally Book) Second look at the PH factors that can partake Listeria Monocytogens.

A PH level for optimum extremity should be between 4.5 and 6.2 when used with the temperature ranges listed above. (Invisible enemy, 1999) According to a battleground by the Amer ican Society of Microbiology, Listeria monoc! ytogenes cells was treated by extravagantly 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 scale sum up agar. (Ritz, M., 2001) Listeria Monocytogenes have been found on pinkish-orange so they are capable of living in the ocean at some level. Next, when treated with an increase of osmotic 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
