In the quest to find the key to a rainforest-dwelling bacterium’s lignin-degrading ability, researchers at the Joint BioEnergy Institute (JBEI) have constructed a gene expression system that outperforms conventional systems, called Jungle Express. Controlling gene expression is crucial to scientists’ ability to perform basic science and biotechnological research to produce enzymes, bio-based products, and biofuels, both at the bench and on industrial scales.

Another Great Year for the Biotech Partners at the Biosciences Area
This past Saturday, August 11, seven Biotech Partners high school students who interned at the Biosciences Area participated at the Biotech Partners end of summer celebration and poster competition. Four of the seven Biosciences interns made it to the finalists round of the poster competition. Mitzy Rubio from the Biological Systems and Engineering (BSE) Division received an honorable mention for “Most Creative Poster” and Raven Young from the Joint Genome Institute (JGI) received an honorable mention for “Best Oral Presentation”.
iCLEM Cohort Concludes Summer Research at JBEI
The Introductory College Level Experience in Microbiology (iCLEM), the Joint BioEnergy Institute’s flagship outreach program, concluded last week with a celebration which included a students’ presentation and a poster presentation by the teachers who assisted the program. Photos of the celebration are available online. Check out also the Twitter campaign in which the students shared highlights of their summer experience at JBEI.
JGI Finds Terpene Synthase Gene Family Conserved in Eucalypts
Terpenes play key roles in plant growth, defense, and environmental interactions. Terpenes are also economically important because of their use in industrial materials, pharmaceutical products, and as biofuel precursors. Collectively, hundreds of terpene compounds have been characterized from eucalypts, a group of 900 tree species belonging to the Myrtaceae (myrtle) family and containing the closely-related genera Angophora, Corymbia and Eucalyptus. As part of a proposal by the DOE’s Joint BioEnergy Institute (JBEI), the JGI worked on resequencing several eucalypt genomes to establish the feasibility of genome wide association studies for genetic traits that are desirable from a biofuels production perspective. By using genomic database alignment tools, researchers searched for TPS genes in the eucalypt Corymbia citriodora. Learn more on the JGI website.
Scientists Discover How to Protect Yeast from Damage in Biofuel Production
Some chemicals used to speed up the breakdown of plants for production of biofuels like ethanol are poison to the yeasts that turn the plant sugars into fuel. Researchers from the UW-Madison-based Great Lakes Bioenergy Research Center, Joint BioEnergy Institute, and several Department of Energy National Laboratories have identified two changes to a single gene that can make yeast tolerate the pretreatment chemicals. They published their findings recently in the journal Genetics. To learn more read the University of Wisconsin-Madison news release.
