A demonstration plant that will produce 5,000 m.t./yr of succinic acid from biomass will be built in Pomacle, France, by BioAmber, a joint venture of Diversified Natural Products (DNP, New York, N.Y.; and Agro Industries Recherche et Developpement (ARD, Pomacle). Succinic acid, used in a variety of products, including cosmetics and foods, is produced mainly from maleic anhydride...

The cost of producing ethanol promises to be reduced by 50% through a process being developed by TNO (Zeist, Netherlands; The reason for the dramatic cut is that ligno-cellulosic material is hydrolyzed in a single step, using concentrated sulfuric acid. In contrast, conventional hydrolysis is a two-step process in which...

Demonstration plants to test six processes for producing ethanol from non-food-based biomass will be built with support from the U.S. DOE ( Between them, the plants will produce more than 130 million gal/yr of ethanol from cellulosic feeds, including agricultural waste and perennial grasses. DOE's goal is to make cellulosic ethanol cost-competitive...

A fungus that is said to be more effective than baker's yeast for the conversion of waste to ethanol has been discovered by researchers at Boras University College (Sweden; The fungus, a saprophyte (of the zygomycetes...
April 1, 2007
Researchers at the Max Plank Institute for Colloids and Interfaces (Potsdam, Germany; have taken a first step towards artificial photosynthesis by developing a metal-free...
March 1, 2007
  Last month, Diversa Corp. (San Diego, Calif.; and Celunol Corp. (Cambridge, Mass.; signed a definitive merger agreement to create what is claimed as a new leader in the emerging cellulose-based ethanol industry. The combined company will be the first to posess integrated end-to-end...

For a biological denitrification process that selectively converts ammonia into nitrogen gas, Paques B.V. (Balk, Netherlands; was among the winners of the EEP environmental award, which was presented at Pollutec 2006 (Lyon, France; 28 November–December 1). Developed in collaboration with Delft University of Technology and the University of Nijmegen (both Netherlands), the...
December 1, 2006
Excelsyn Molecular Development (Holywell, U.K.; has made a “major” advance in its development of improved technology to produce the unnatural amino acid tert-L-leucine (tert-butyl glycine; TBG) — a precursor for synthesizing...
December 1, 2006
An innovative design of a pulsed-electric-field (PEF) treatment unit for the inactivation of Escherichia coli bacteria has been developed by associate professor Mohammed Farid and Sally Alkhafaji at the Chemical and Materials Engineering Department of the School of Engineering, the University of Auckland, New Zealand; The system includes multipass PEF treatment chambers that were...
December 1, 2006
Mascoma Corp. (Cambridge, Mass.; has raised $30 million in its second round of Venture funding — led by General Catalyst Partners (Cambridge, Mass.) — to further develop a new way to make bioethanol from cellulose. Mascoma aims...
December 1, 2006
Researchers from Pacific Northwest National Laboratory (PNNL; Richland, Wash.; and their collaborators have discovered that certain microorganisms can be stimulated to bind uranium from soil when served ethanol for an hour per day. The microbes could be used to immobilize...
November 1, 2006
Cellulose accounts for about 40% of the planet’s total photosynthesis yield (about 1.8 trillion m.t./yr), but the material has not been fully utilized as a chemical resource so far. That’s because the methods currently available for converting cellulose into useful chemicals have drawbacks, such as: low activity, for degradation by enzymes; poor selectivity and difficult separations, for...
November 1, 2006
Over the last three years, DuPont (Wilmington, Del.; has been developing technology to break down the complex sugar matrix of corn stover as a means for making ethanol from cellulose in high yield. Although there is more research to be completed, the company is ready to take the next step to bring cellulosic ethanol to market...

GE Healthcare (Chalfont St. Giles, U.K.; and BAC B.V. (Naarden, Netherlands; are collaborating to develop new affinity-ligand...
October 1, 2006
      Biomass has come center stage in the pursuit of reduced dependence on finite - not to mention geopolitically sensitive - quantities of fossil fuels such as petroleum, coal and natural gas. And while ethanol produced from corn is one promising path for biomass, it is by no means the only one. The number of known viable raw materials is vast, and the assortment of feasible downstream...
October 1, 2006
Richard Milner, a Honary Fellow at CSIRO Entomology (Canberra, Australia;, has developed a rare native fungus, Metarhizium, into an environmentally friendly control for grass-hopper-type (including locust) agricultural pests. Metarhizium is a naturally occurring soil fungus that is...
