22 COV members from academic institutions and other federal agencies.
The COV is charged to assess the processes used to:–solicit, review, and recommend proposal funding actions –manage ongoing research programs–respond to the recommendations of the previous COV in 2005.
Specific program elements to be reviewed include:– Genomics:GTL (including the Bioenergy Research Centers)– Carbon Sequestration– ELSI– Low Dose Radiation Research– Radiochemistry and Instrumentation– Artificial Retina– Joint Genome Institute– Structural Biology
(Medical Sciences programs were merged with Life Sciences Research programs in 2006 and will be undergoing their first COV review.)
A report will be provided at the next BERAC meeting.

BioEnergy Science Center (BESC)BioEnergy Science Center (BESC)
• Strong central strategic focus on overcoming “recalcitrance” (resistance of plant fiber, or lignocellulose, to breakdown into sugars) as major route to cost savings and cost-effective biofuels production
• Longer-term goal of “Consolidated Bioprocessing” (CBP) – one-microbe or microbial community approach going from plants to fuel
• Working directly on energy crops – switchgrass and poplar • Nearly completed development new high-throughput pipeline to screen
thousands of genetic variants of switchgrass and poplar for amenability to deconstruction
• Performed bioprospecting in Yellowstone National Park for cellulases that operate more efficiently at very high temperatures – using metagenomics to find new, more effective cellulases
• Pursuing synthetic biology to make Clostridium thermocellum (CBP microbe) more efficient at fermenting and to re-engineer the cellulosome
• Strongly committed to achieving cost-saving, commercializable breakthroughs in five years
• Will eventually have the opportunity to test discoveries in a demonstration biorefinery being constructed by the state of Tennessee 40 miles from BESC

Joint BioEnergy Institute (JBEI)Joint BioEnergy Institute (JBEI)
• Strong basic science-oriented approach, looking for fundamental transformational, game-changing breakthroughs in basic science
• Focusing on model crops of Arabidopsis and rice (and on switchgrass) – with idea that basic science breakthroughs can be achieved more rapidly on model crops and then transferred to energy crops
• Innovative approach to lignin – rather that treat lignin as a wall to be broken through, change the monomer composition of lignin to make it more cleavable and its byproducts less toxic to microbes used in fuel synthesis
• Progress on pretreatment – success already using ionic liquids as an alternative pretreatment method—yields no toxic byproducts and de-crystallizes the cellulose – significantly accelerates enzymatic hydrolysis
• Especially creative on the microbial side – using synthetic biology, looking beyond ethanol to synthesis of butanol, isopentanol, hexadecane, geranyl decanoate (toward gasoline, diesel, jet fuel)
• All researchers will work together in a newly leased lab building near Berkeley – move to new quarters in Emeryville nearly completed
• Fostering strong connections to larger S.F. Bay Area Biotech Community, which is becoming hub of bioenergy technology and venture investment

Great Lakes Bioenergy Research Center Great Lakes Bioenergy Research Center (GLBRC)(GLBRC)
• Reflecting agronomic orientation of the two universities, focusing on a wide range of plants, including both “model” plants and potential bioenergy crops – also in some ways the most diverse research agenda
• Alternative approach to plants – in addition to working to overcome “recalcitrance” of lignocellulose, GLBRC will be re-engineering plants to produce more starches and oils, which are more easily processed into fuels – oils for biodiesel
• Alternative approaches to fuels:– Exploring chemical catalytic as well as enzymatic/microbial
conversion – producing hydrocarbons – green gasoline, diesel, aviation fuel – new approach of “aqueous phase processing” yields hydrocarbons from sugars
– Developing microbial biorefineries that can use sunlight and plant biomass to generate hydrogen, electricity, or high-energy chemicals
• Includes major “thrust area” on sustainability of biofuels production, comprehensively studying the environmental and socioeconomic dimensions of moving to a biofuels economy (not requested in FOA, but widely praised by peer reviewers and important for moving toward President’s “20 in 10” goal) – of growing importance in new societal debate on biofuels – actively working to educate public, community

ASCR-BER Joint EffortsASCR-BER Joint EffortsAccelerating Progress Toward GTL GoalsAccelerating Progress Toward GTL Goals
PAST: SciDAC and GTL Efforts:Current research within the SciDAC/GTL program includes new
molecular dynamics codes for very large biological systems such as Cellulases, network analysis for hydrogen metabolism, and programs, such as BACTER, aimed at bridging the computational/experimental microbiology gap.
PRESENT: Multiscale Modeling Efforts between GTL and ASCR:Proposals were solicited for joint activities to interface computational
and mathematical efforts with biological mission relevant research directions. Areas under consideration include large scale genotyping and simulations of microbial communities, large scale network analysis and coarse graining of dynamical processes.
FUTURE: GTL Systems Biology Knowledgebase Workshop:A workshop will outline the mechanism necessary to create a community
driven resource for the archival, curation and integration of data and information that is relevant to the organisms of interest and mission areas of DOE. Particular emphasis is given to creating a computational and collaborative infrastructure. (Reported by Susan Gregurick yesterday.)

Structural Biology – Pending IssuesStructural Biology – Pending Issues
• National Synchrotron Light Source to be replaced. How will life sciences access be developed and what new techniques will be enabled by the facility?
• How important are neutron techniques and how much should BER invest in
user stations for them? [This question from 2005 is still unanswered.]
• To what extent should the structural biology facility access program focus
on needs of the Genomics:GTL program? Several beamlines are being
used in GTL technology development and/or research, will more, or new
types, be needed?
• Are there areas for which a program solicitation would be desirable, perhaps
jointly with other agencies?

• Other new national user facilities, such as the Linac Coherent Light Source (LCLS), and major facility upgrades. What is the potential impact on life sciences in general and on BER research programs?
