Biocatalysis

The cover story in the October 19, 2009 Wall Street Journal names 5 technologies that could, if successful, radically change the world energy picture, and next generation biofuels from algae is one of them. I would broaden the category to include designer microorganisms of the type being developed by Synthetic Genomics, but in general, I agree. Converting carbon dioxide into fuels using energy from the sun to drive the process would be a game-changer. Let’s hope it works out.

In a press release yesterday Massachusetts-based Qteros, developer of the Q-microbe “”superbug” (actually Clostridium phytoferrans, but “Q” is much easier to pronounce and type).

The processes uses a material the company calls Recyllose-sewage sludge solids that are high is cellulose. Turning sewage sludge into ethanol offers a big opportunity for Qteros, which is partnering with Israel-based Applied CleanTech to develop the technology. Recyllose is a particularly good type of cellulosic feedstock as it contains very low amounts of lignin, the plant cell wall component that is difficult to degrade. Qteros-ACT scientists claim 120-135 gallons of ethanol per ton of Recyllose, and titers of 9% ethanol currently.

Quoting from the press release: “Our customer is every municipality that has a wastewater treatment plant,” said Jeff Hausthor, Qteros co-founder and senior project manager. “It will provide a value-added product for municipal wastewater plants, thereby making treatment plants much less expensive to run and helping local governments throughout the world with their constrained budgets.”

Israel Biran, ACT’s CEO, added, “It also helps answer the question of what municipalities can do with their sewage sludge, a major challenge now facing every wastewater treatment plant operator.”

There has been a PR blitz over the past 24 hours, and it appears to be well-merited.
