Below, are today’s three chosen agricultural-related news picks.
1) Bacteria and Fungi Together: A Biofuel Dream Team? From Scientific American by Erin Brodwin. Researchers at the Univ. of Michigan have created isobutanol from cornhusks, E. coli, and the fungi Trichoderma reesei. “Often when scientists arbitrarily combine organisms in the laboratory, one will outgrow another, driving it to extinction. Yet T. reesei and E. coli exhibited the one characteristic necessary for any stable system: synergy. “We allowed the natural dynamics to emerge,” Minty says. This interaction, which Minty and his team call a cooperator-cheater mechanism, allow the bacteria and fungi to maintain a state of balance. When the fungi degrade materials in the cornhusks into sugars, some of that action takes place on its surface. T. reesei thus gets the first crack at using them, preventing E. coli, which is far more efficient at snatching them up, from stealing all of the sugars and potentially starving out T. reesei.” K.M.: A number of years ago the very popular fungi-will-solve-the-world’s-problems-guy, Paul Stamets, sounded like making biofuel with fungi was a no-brainer. I’ve wondered what has happened to his project, but this article would suggest it is a hopeful field of study. Don’t miss comment #1. @Talli calls this project bogus.
2) Taxpayer Funded Sugar-for-Ethanol Program: “U.S. sugar processors have offered to sell 90,150 tonnes of sugar to the U.S. Department of Agriculture as part of its “sugar-for-ethanol” program, designed to reduce an oversupply and boost domestic prices, the government said on Wednesday. The USDA will sell the sugar to ethanol producers, aiming at averting mass forfeitures of sugar that was used as collateral for government-backed loans. The Obama administration inaugurated a program last week to buy unwanted sugar and sell it at a loss to ethanol makers to produce more biofuels and mitigate a costly sugar surplus.”
3) Biobased butanol, butadiene and BDO are having a hot year: Jim Lane tells us “complex, multi-carbon drop-in renewable diesel, jet fuels and biodiesel have been the expansion story for advanced biofuels in the past three years — if any platform could be described as the “hottest of the hottest” right row, four-carbon chemicals and fuels are right in the heart of the roaster right now.” K.M.: Corn growers are no doubt quite hopeful about using corn to produce this drop-in fuel.
BONUS: I highly recommend viewing this slideshow with excellent and informative commentary on no-till and cover-crops.
