This microbe's for you: Brewery waste becomes scientific fodder for producing liquid biofuels
Date:2/27/2011

ITHACA, N.Y. Gaining new insight into how efficiently the microbes in large bioreactors produce methane from brewery waste, Cornell scientists hope to use their new knowledge to shape these microbial communities to produce liquid biofuels and other useful products.

The scientists Largus T. Angenent, associate professor of biological and environmental engineering, and the first author and research associate Jeffrey J. Werner, published "Bacterial Community Structures Are Unique and Resilient in Full-Scale Bioenergy Systems" (Proceedings of the National Academy of Sciences, Feb. 22, 2011.)

The scientists had access to a plethora of data, thanks to a collaboration with engineers at Anheuser-Busch InBev, which makes Budweiser beer and operates nine domestic beer breweries that treat wastewater in bioreactors. They took regular samples of bioreactor sludge from each of the facilities over the course of a year and, using state-of-the-art genome sequencing software, they analyzed more than 400,000 gene sequences of the microbes in the sludge.

Among the thousands of species of bacteria, the researchers identified 145 types that were unique to each of the nine facilities -- showing that each bioreactor hosted a specific microbial community. In their analysis they observed that certain types of bacteria called syntrophs had surprisingly stable populations.

"The cool thing we found was that if you're looking at these thousands of species of bacteria, it's a very dynamic system with things dying off and replacing them," Werner said. "There are certain signature populations that are resilient. Even if they get disturbed, they come right back up."

Typically inside these million-gallon bioreactor tanks, the microbial populations in the sludge interact and one of them produces methane gas. Anheuser-Busch InBev recoups 20 percent of its heat energy use through the methane produced, saving the company millions of dollars
