Cheese Production
L. lactis subsp. lactis (formerly Streptococcus lactis) is used in the early stages for the production of many cheeses, including Brie, Camembert, Cheddar, Colby, Gruyère, Parmesan, and Roquefort. The state Assembly of Wisconsin, also the number one cheese-producing state in the United States, voted in 2010 to name this bacterium as the official state microbe. It would have been the first and only such designation by a state legislature in the nation, however the legislation was not picked up by the Senate.
The use of L. lactis in dairy factories is not without issues. Bacteriophages specific to L. lactis cause significant economic losses each year by preventing the bacteria from fully metabolizing the milk substrate. Several epidemiologic studies showed the phages mainly responsible for these losses are from the species 936, c2, and P335 (all from the family Siphoviridae).

Famous quotes containing the words cheese and/or production:
“Upscale people are fixated with food simply because they are now able to eat so much of it without getting fat, and the reason they don’t get fat is that they maintain a profligate level of calorie expenditure. The very same people whose evenings begin with melted goat’s cheese ... get up at dawn to run, break for a mid-morning aerobics class, and watch the evening news while racing on a stationary bicycle.”
—Barbara Ehrenreich (b. 1941)
“Perestroika basically is creating material incentives for the individual. Some of the comrades deny that, but I can’t see it any other way. In that sense human nature kinda goes backwards. It’s a step backwards. You have to realize the people weren’t quite ready for a socialist production system.”
—Gus Hall (b. 1910)
