Or how about drinking a nice cold one with some buddies after work at a local bar‚ sound nice doesn?t it? Beer has been around for many years and will probably be around for many more. A beer is any variety of alcoholic beverages produced by the fermentation of starchy material derived from grains or other plant sources. The production of beer and some other alcoholic beverages is often called brewing. Most every culture has there own tradition and the own take on beer‚ thus producing many different

highest-quality penicillin after a worldwide search. The discovery of the cantaloupe‚ and the results of fermentation research on corn steep liquor at the Northern Regional Research Laboratory at Peoria‚ Illinois‚ allowed the United States to produce 2.3 million doses in time for the invasion of Normandy in the spring of 1944. Large-scale production resulted from the development of deep-tank fermentation by chemical engineer Margaret Hutchinson

transport vehicle. One of the ways to get fuel from the biomass is a process called fermentation‚ whereby micro-organisms and bacteria break down a starchy substance into sugar‚ and then they convert the sugar to form alcohol. The micro-organisms and bacteria have the ability to do this due to their metabolisms. The glucose allows the micro-organisms to acquire energy anaerobically. The alcoholic fermentation occurs when yeast transforms sugar‚ cellulose and starch (carbohydrates) into carbon dioxide
