Construction is underway in France on a pilot plant for what is believed to be the first fermentation process capable of directly producing the light olefin isobutene. Global Bioenergies (Evry, France; www.global-bioenergies.com) expects to begin operations of a 500-L fermentation facility in the second half of 2014 and plans to follow that with a 5,000-L fermenter in Germany the following year. Isobutene...

A new process-intensification technology to accelerate the rate of enzymatic reactions has been developed by researchers from the Dept. of Chemical Engineering, University of Bath (U.K.; www.bath.ac.uk). The so-called spinning cloth disc reactor (SCDR) is based on, but extends the principles of, the conventional spinning disc reactor (SDR). The SCDR also uses centrifugal forces to allow the spread of a...

Extraction of palm oil generates large amounts of lignocellulose-rich byproduct known as empty fruit bunch (EFB), which is usually wasted. A new process for utilizing this waste to make lactic acid has been developed by a team of researchers in Singapore. Up to now, it has been difficult to find cost-effective processes for the production of L-lactic acid, which has inhibited the commercial production of...

The effluent discharged by domestic industries in Japan amounts to approximately 11.1 billion ton/yr. Most of this waste is comprised of relatively low concentrations of organic matter. Today, most of this effluent is treated by aerobic biotreatment (activated sludge). However, activated sludge treatment not only consumes large amounts of electric power needed to run blowers or fans, but it also produces...

Industrial microbiology continues to hold the promise of producing an increasingly large array of commercially important chemicals because an ever-wider number of useful microbes is being developed and successfully deployed at commercially viable scales. Today, many of these bio-based chemicals are needed in quantities so large that existing fermentation technology is inadequate, and this is pushing the...

In April development tests, Cobalt Technologies (Cobalt; Mountain View, Calif; www.cobalttech.com) produced n -butanol at the fermentation scale of 100 m3 per run, demonstrating lower production cost than butanol produced from petroleum. This represents production that is a factor of 10 larger than previous trials conducted at the National Renewable Energy Laboratory (NREL; Golden, Colo.; www.nrel.gov)...

Squalane, an emollient used in cosmetics, will be the first product of a biotechnology pilot plant now being started up by Nucelis Inc. (San Diego, Calif.; www.nucelis.com), a spin-off from Cibus (also of San Diego). The plant will use Cibus’ Rapid Trait Development System (RTDS), a new gene-editing technology, to enable naturally occurring yeast to increase their production of squalene, the...

Lately there has been much renewed interest in fermentative production of n-butanol from renewable biomass as an industrial solvent and liquid fuel superior to ethanol that could be used as a substitute for gasoline. An improved butanol production through the reinforcement of the direct butanol-forming route in Clostridium acetobutylicum has been reported by a Korean team, which includes scientists from...
