Development of robust microbial platforms for bioproduction requires strains that have been engineered to have efficient carbon uptake, energy generation, tolerance to biomass pretreatment byproducts and the export of final product. Many of these optimizations require expression and overexpression of native and heterologous membrane proteins. Over the years, scientists at the U.S. Department of Energy’s Joint BioEnergy Institute (JBEI), and others have successfully found many such engineering targets. However, JBEI has also found that expression of membrane proteins is challenging and can also impact the microbial growth, thus negatively limiting the use of these discoveries. Read more from JBEI.
