acid--with enough sensitivity to monitor the health of a few thousand cells confined in a small volume. (For more detail see "New device can help defend against novel biological agents" at [http://exploration.vanderbilt.edu/news/news_microphys.htm].)...
Bacteria that cause tooth decay able to survive without important biochemical pathway
...aten, the S. mutans population explodes, excreting lactic
acid as it digests sugar. The acid makes life difficult for other helpful bacteria and demineralizes tooth enamel, causing decay. According to the U.S. Centers for Disease Control and Prevention, 95 percent of adult Americans suffer from tooth decay....

acid. LAB are also known for their "promiscuity," or the ability to accept foreign DNA, then produce...
Hopkins researchers discover genetic switch that turns off an oxygen-poor cell's combustion engine
...ell's survival depends on it to convert glucose to lactic
acid through glycolysis even in the presence of ample oxygen. Disruption of the switch by a drug may cause cancer cells to pollute themselves with toxic oxygen molecules and undergo apoptosis or cell death. The new finding, made by Hopkins graduate s...
Lactic acid not athlete's poison, but an energy source - if you know how to use it

AZTI-Tecnalia obtains isomers of conjugated linoleic acid from micro-organisms
...TI-Tecnalia was to study the efficiency of certain lactic
acid bacteria on the production of potentially fun...ugated isomers. Results indicate that, amongst the lactic

Iowa State researchers improve soy processing by boosting protein and sugar yields
...hey can replace an expensive compound used to grow lactic
acid bacteria, Khanal said. The bacteria produce nisin, a valuable natural food preservative that's also used in cosmetic and health care products such as mouthwash and toothpaste. "Our preliminary economic analysis showed that the proposed techno...

...ons. Previous studies have focused largely on the lactic
acid bacteria (LAB) group and many have shown beneficial effects in small animal models challenged with gastrointestinal infection. In the study pigs were divided into two groups, one of which received milk containing five LAB probiotic strains and...
Plastic that degrades in seawater could be boon for cruise industry and others
...these compounds may include water, carbon dioxide, lactic
acid, glycolic acid, succinic acid, caproic acid and L-lysine, all of which can be found in nature, they add. Because the new plastics are denser than saltwater, they have a tendency to sink instead of float, Storey says. That feature also could p...
