Vigorous microbial growth in bioreactors raises cell density, which is a source of heat stress and can hinder production efficiency. To address the issue, scientists have tried introducing genes for heat-shock proteins (HSPs) into workhorse industrial bacteria like Escherichia coli,…
Light olefins, such as ethylene and propylene, are primarily made by the catalytic cracking of crude oil. Alternatively, two other methods were developed during the time of high oil prices, both of which convert synthesis gas (syngas) to olefins: the…
The first commercial-scale, natural-gas-fermentation facility in the U.S. will break ground by the end of 2016, according to Alan Shaw, CEO of Calysta Inc. (Menlo Park, Calif.; www.calysta.com). In a collaboration with agricultural giant Cargill Inc. (Minneapolis, Minn.; www.cargill.com), Calysta…
Bio-based PET Later this year, Suntory Holdings Ltd. (Osaka, Japan; www.suntory.com) will start up a demonstration plant in Silsbee, Tex. for the production of 100% bio-based PET bottles. The company will introduce these PET with its Suntory Beverage & Food’s…
Graphene has received much attention as material for membranes due to its high surface area, high mechanical strength and chemical stability. Graphene-based membranes are also expected to exhibit much greater permeability than the current state-of-the-art membranes. However, it has been…
An efficient, energy-saving process for making carbon fibers (diagram) is being developed by a collaboration team of the University of Tokyo, the Institute of Industrial Science and Technology (AIST), Toray Industries, Inc., Teijin Ltd., Toho Tenax Co. and Mitsubishi Rayon…
The traditional method for recovering platinum-group metals (Pt, Pa, Ir, Os, Rh, Ru and Au) is not economically viable in the case of low-grade deposits, but researchers from the Western Australian School of Mines, Curtin University (Perth; www.curtin.edu.au) and the…
A partnership between DuPont Industrial Biosciences (Wilmington, Del.; www.dupont.com) and Archer Daniels Midland Co. (ADM; Chicago, Ill.; www.adm.com) has developed a less costly and more efficient process for producing bio-based furan dicarboxylic methyl ester (FDME) from the six-carbon sugar fructose.…
A team from the National University of Singapore (www.nus.edu.sg), led by assistant professor Duong Hai Minh from the Dept. of Mechanical Engineering, has succeeded in converting paper waste into cellulose aerogels that are nontoxic, ultralight, flexible, extremely strong, and water…
Construction has begun on a testing and development facility for a bio-based process to produce benzene, toluene and xylenes (BTX) from woody biomass. The test facility is intended to demonstrate all unit operations and prove process economics for the Bio-TCat…
