Bacteria-based production method patented

Note to the attorneys that filed this idiotic patent: it's called "fermentation", guys, and I suspect that there may be some prior art, some of it in cuniform on clay tablets that are about 4500 years old ...

Look on a package of gum and you'll probably notice the word mannitol. Scientifically described as a sugar alcohol, mannitol is a minty-tasting ingredient found in many foods and boasts fewer calories than table sugar. Though made by some plants and algae, mannitol is commercially produced by chemical means. In February, however, the Agricultural Research Service (ARS) obtained a patent on a method that weds nature with modern technology. ARS chemist Badal Saha calls his method "biobased" because it involves feeding high-fructose corn syrup to the bacterial species Lactobacillus intermedius in a deep-tank fermentor. There, over several hours' time, the bacteria convert 72 percent of the syrup into mannitol.

Notes: If you put a <mailto:> link in the URL field your address will not be mangled: this could be a bad idea as your email address could be easily harvested by bots designed for SPAM. The comments field should now format correctly for line feeds and carriage returns: when you hit the 'Enter' or 'Return' keys in your comment it should break to a new line. The text should wrap cleanly. Please let me know if it doesn't. No HTML tags will pass through - entering links seems to be the main cause of comment SPAM. Also, please be sure that Javascript is enabled in your browser before attempting to post a writeback. Sorry for any inconvenience, but this really helps cut down on the amount of comment SPAM I have to deal with.
