CHICAGO - The search for easier and cheaper ways to convert tons of Illinois biomass like perennial grasses into energy has taken a major step forward. A team at the Great Lakes Bioenergy Research Center (GLBRC) has found a way to identify specific genetic factors that could lead to less expensive biofuel production.
Scientist David Keating of the University of Wisconsin led the team that has figured out a way to "turn off" certain genetic switches, one at a time, to determine a way to produce a bacterium that can turn crop waste into fuel.
"If we disrupt that gene and now the organism can't degrade this material, we know that gene is really important and that's a gene we want to study further."
Through this process of elimination, the genetic detectives are hoping to find the genes that impact turning waste to fuel. Keating says the new genetic method will allow scientists to understand how bacteria carry out this conversion, which should provide new avenues for improving the industrial process.
He explains microorganisms, such as bacteria and fungi, are capable of converting biomass to simple sugars, but historically, they have been difficult to study using genetic approaches.
"What this really involves is a way to be able to identify which genes matter, which ones don't, and to really harness the power of the bacterial genome to improve things."
Currently, the cost to convert biomass to fuel is higher than traditional energy sources such as oil, which makes biomass less attractive as an alternative. The new breakthrough could help bring the conversion costs down significantly, to provide a cheaper and renewable Midwest alternative to oil.

New federal funding aims to revolutionize solar energy access within New Mexico's Native American communities and benefit the state overall.
The Environmental Protection Agency's $7 billion "Solar for All" program is designed to create new or expanded low-income solar programs.
Talia Martin, co-executive director of the National Tribal Program for GRID Alternatives, said the funding will help bridge the clean energy gap in Native American communities.
"In New Mexico, tangible impacts would be for household savings," Martin explained. "Which means working directly with the tribes to ensure that the savings are going to individual households as well as to the community as a whole."
According to Martin, the $62 million EPA grant awarded to the GRID Tribal Program is its largest ever. Nationwide, the agency's program is set to help at least 4,700 households in Native American communities. Across the U.S., the EPA said the program will enable more than 900,000 low-income households and disadvantaged communities to benefit from distributed solar energy.
Martin emphasized the program will allow GRID to help bolster solar storage capabilities and implement essential upgrades, while at the same time advancing their mission to support the self-determined efforts of Native American tribes to deploy clean energy on tribal lands, arguing it will be important to recruit contractors who understand the needs of tribal communities they're working with.
"It's an amazing window for Indian Country to be involved in energy development," Martin pointed out. "We want to just help foster all these relationships that it is going to take to do that."
The state of New Mexico also received a grant of $156 million from the program to overcome existing barriers to widespread adoption of distributed solar generation. In addition to the federal money for solar, Array Technologies announced last week it will build a new $50 million solar manufacturing campus near Albuquerque.

A round of public testimony wrapped up this week as part of renewed efforts by a company seeking permit approval in North Dakota for an underground pipeline carrying carbon emissions. Economic benefits were again touted but the plan still has opponents.
Last year, North Dakota's Public Service Commission denied a permit request from Summit Carbon Solutions, which wants to build a maze of pipelines in several Midwestern states. Emissions from ethanol plants would be captured for underground storage in North Dakota.
Skott Skokos, executive director of the Dakota Resource Council, said they remain unconvinced it would be a worthwhile project.
"It felt like déjà vu," Skokos observed. "I don't think Summit did anything to relax the concerns of the public."
Company officials have submitted a new application with a revised route as they try to ease concerns about safety and landowner rights. During comment periods, Summit leaders and other speakers discussed how the project would provide economic boosts, including corn prices. However, skeptics restated their concerns about potential ruptures and lasting negative effects on the landscape.
Skokos pointed out large carbon-capture projects like these have yet to prove themselves, noting smaller initiatives are not as likely to rile up opponents. He pointed to the Red Trail ethanol plant in North Dakota.
"They're storing it, basically, almost on-site, next to the facility and they're not affecting a bunch of landowners in the process," Skokos emphasized.
The Summit regulatory case has two upcoming public hearings in North Dakota, one scheduled for May 24 and the other on June 4. The company has run into similar opposition and permitting headwinds in other states, including South Dakota.

Leaders concerned about pollution and climate change are raising awareness about a ballot measure this fall on whether the state should mandate buffer zones around new oil and gas wells.
Voters will be asked to uphold or revoke Senate Bill 1173, which would require a 3,200-foot setback around any new well near schools, neighborhoods and hospitals.
Meghan Sahli-Wells, former mayor of Culver City and a leader with the group Elected Officials to Protect America, fought to phase out the Inglewood oil field and said no community should be a sacrifice zone.
"A study from Harvard found that in California, 34,000 people died in 2018, prematurely, from fossil fuel air pollution," Sahli-Wells pointed out. "These figures are three times higher than other studies."
The Stop the Energy Shutdown campaign, supported by the California Independent Petroleum Association, opposes the setback rule, arguing it could constrict local supply and cost jobs in the industry. A court put the bill on hold pending the outcome of the November election. A "yes" vote would keep the setbacks. A "no" vote would rescind them.
Clean energy advocates are also speaking out against companies operating older low-producing wells rather than pay to shut them down and seal them up properly.
Ahmad Zahra, a city council member in Fullerton, said Assembly Bill 2716 would incentivize their closure by charging companies $10,000 a day to operate so-called "stripper wells."
"We have over 40,000 oil wells currently sitting orphaned or idle, leaking methane and volatile organic compounds into the air, water and soil," Zahra emphasized.
Other states are following California's lead. Rep. Debbie Sariñana, D-Albuquerque, New Mexico, is sponsoring a bill to require setbacks near sensitive locations since more than 32,000 children in the state attend school within a mile of an oil and gas extraction site.
"Over 80 schools in northwestern New Mexico - the San Juan Basin and southeastern New Mexico, the Permian Basin - are within one mile of an oil and gas well," Sariñana noted. "Some schools are surrounded by dozens and even hundreds of wells within a single mile."
