Scientists at Kao Corp. (KAO; Tokyo, Japan; chemical.kao.com) have discovered an enzyme that has the potential for producing large quantities of medium-chain (C12) fatty acids (FAs), which are the main components of natural oils, such as palm-kernel and coconut-palm oils. Such FAs are precursors to surfactants used in shampoos and detergents. The discovery could lead to an alternative route to such...

Algae Systems LLC (Daphne, Ala.; www.algaesystems.com) has inaugurated a demonstration plant that integrates municipal wastewater treatment with the cultivation of biofuel-producing algae. Pretreated and disinfected municipal wastewater is passed to Algae Systems offshore floating-bag photobioreactors (PBRs), which are located in a bay off of Daphnes coast. There, the oxygen, nitrogen and phosphorous from the...

What is said to be the world’s first fermentation pathway from methane to lactic acid has been demonstrated by Calysta, Inc. (Menlo Park, Calif.; www.calysta.com). The fermentation process begins with an organism that feeds off of methane rather than typical sugar-based feedstocks and, through synthetic biology, has been altered to convert that methane to high levels of lactic acid. This lactic acid...

A less expensive process for producing biodegradeable polyhydroxyalkanoate (PHA) plastics from renewable feedstocks is being scaled up by a factor of six, resulting in a 30,000–60,000-lb/mo pilot facility. The improved PHA process — developed by Meredian Inc. (Bainbridge, Ga.; www.meredianpha.com) — stems from a patent portfolio initially established by Proctor and Gamble. The microbial...

With a separate algae-based technology, Algal Scientific has invented a sterile fermentation process for making beta-1,3-glucan from algae that has lower costs than those associated with fermenting the molecule with yeast. Beta-1,3-glucan is a polysaccharide that boosts immune-system function in humans and livestock animals. As a feed supplement, beta-glucan can eliminate the use of antibiotics as growth...

In April, a demonstration plant started up that makes bioethanol from cassava residue — a byproduct of tapioca production. The demonstration plant, located at the cassava starch plant of EBP Ethanol Co. in Sa Kaeo Province, Thailand, is part of a four-year, $7-million project of New Energy and Industrial Technology Development Organization (NEDO) and Thailands National Innovation Agency. The project...

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 chemical process is set to create bio-based p-xylene from cellulosic waste. Micromidas (West Sacramento, Calif.; www.micromidas.com) opened a pilot plant in December 2013 that converts cellulosic waste materials, such as rice hulls, switchgrass, sawdust and cardboard to bio-based p-xylene. The Micromidas process is unusual in that it does not require the cellulose to be saccharified first, and both...

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...
