A high-throughput, cost effective method for discovering gene function in microbes under various environmental conditions is among the winners of R&D Magazine’s 2017 R&D 100 Award. The technology, called Dual Barcoded Shotgun Expression Library Sequencing (Dub-seq), was developed by Adam Arkin, Adam Deutschbauer, Vivek Mutalik, and Pavel Novichkov of the Environmental Genomics and Systems Biology (EGSB) Division. Dub-seq combines the shotgun expression library method and next generation sequencing method developed through the ENIGMA program. Now in its 55th year, the prestigious R&D 100 Awards program recognizes the most innovative inventions of the prior year. Three other Berkeley Lab technologies were likewise honored at a black-tie gala on Nov. 17, and Berkeley Lab was included as a co-nominee on two additional winning technologies.
