Document Summary
Food flavoring agents and preservatives: organic acids such as citric, malic and ascorbic acids and monosodium glutamate (msg) are microbial products commonly used in foods. The latter are used for secondary oil recovery in oil fields, lubricants in drilling oil wells, gelling agents in foods and thickeners in both paints and foods. 08/01/2019: organic chemicals, acetone, methanol, butanol and ethanol all have multiple applications in industrial settings. 08/01/2019: methanosarcina -> methane producing, methane is only produced by archaea, classifying archaebacteria three types (1) methanogens (2) extreme halophiles. The bacteria survive inside the salt crust, even though it has been exposed to sun-baked summers and freezing winters in california"s owens valley. 08/01/2019: taxonomic diversity of useful bacteria, most of the microbiology biotech come from the bacteria, some from eukarya (fungi) 08/01/2019: gram positive bacteria, many endospore-forming obligate anaerobes, clostridium - clostridium acetobutylicum and wwi, acetone, butanol -> used to make gun powder.
