US application 20150140640 on microorganisms capable of growing on crude glycerol
Disclosed herein are microorganisms capable of growing on crude glycerol and/or glycerol and/or methanol, or combinations thereof. In some embodiments the microorganisms are knallgas bacteria that produce or secrete at least 10% of lipid by weight. Also disclosed are methods of converting crude glycerol and/or glycerol and/or methanol produced as byproduct of processes including but not limited to biodiesel production, into organic carbon molecules such as triacylglycerol useful for industrial processes including but not limited to the production of additional biodiesel. Also disclosed are methods of manufacturing chemicals or producing precursors to chemicals useful in oleochemicals, jet fuel, diesel fuel, and biodiesel fuel. Exemplary chemicals or precursors to chemicals useful in fuel and/or oleochemical production are alkanes, alkenes, alkynes, fatty acid alcohols, fatty acid aldehydes, methyl esters, ethyl esters, alkyl esters, with carbon chains between five and twenty four carbon atoms long.
**A recent post on biofuelsdigest, titled Kiverdi: Biofuels Digest’s 2015 5-Minute Guide, did not mention glycerol conversion. The post did note:
Kiverdi is in the class of gas fermentation companies – like, say, Coskata, INEOS Bio or LanzaTech, and a modular bolt-on to syngas production processes, such as commercially available gasification or steam reforming technologies. Their differentiating point? The ability to produce a wide range of commercially useful mid- and long-chain carbon molecules using proprietary microbes, co-designed bioreactors, and integrated operations.
