With bio-based chemical production growing, and several newer companies ready to enter commercial production, indications are that biologically derived chemicals will be an increasing force in the petrochemicals market. But bio-based chemical producers must confront the bottom-line requirements of product performance and cost, rather than riding their products’ environmental benefits. Susan Sun...

Uhde GmbH (Dortmund, Germany; is developing a new process for producing lactic acid (LA) — a monomer for making the biodegradable plastic polylactic acid (PLA) — that does not require a distillation step. As a result, savings in steam and electrical power are calculated to be up to €100/ton of LA, says Joachim Schulze, head of Uhde’s biotechnology division. In...

Researchers from the Environmental Biotechnology Cooperative Research Center (Sydney and Perth, Australia; have developed a new way to harness bacteria to biodegrade odor-causing substances. Traditional biofilters typically employ compost supported on wood chips to trap the odor-producing substances, and rely on micro-organisms in the compost to break down those substances. The...

With traditional petroleum-derived feedstocks facing relentless economic and environmental pressures, it’s no surprise that stakeholders throughout the chemical process industries (CPI) have been in hot pursuit of alternative routes for producing commodity and specialty chemicals and polymers from cheap, plentiful renewable feedstocks. The most promising routes are based on agriculturally derived...

Hiroshi Abe and colleagues at Biochemical Group of Research Institute for Innovation in Sustainable Chemistry, National Institute of Advanced Industrial Science and Technology (Tsukuba, Japan; have discovered a strain of acetic-acid bacteria (which normally oxidize ethanol into acetic acid) that effectively converts highly concentrated (22%) glycerin into D-glyceric acid. The researchers...

Today, stakeholders seeking to produce platform chemicals from renewable feedstocks are evaluating competing routes — based on, for example, oxidation, reduction, selective bond breaking, selective bond formation, and the selective dehydration of sugars — for breaking down complex starting materials into simpler, more versatile building block molecules. “The focus of this approach is to zero in on a...*_4841.html

Because of the difficulties associated with separating it from lignocellulosic feedstocks, “lignin has typically been burned by papermakers to produce process heat or power. This is a tragic waste of a good source of carbon,” says Joseph J. Bozell, associate professor, Biomass Chemistry, Forest Products Center, University of Tennessee (Knoxville). Though challenging, the use of lignin to...*_4842.html

Dow is currently building a 770-million-lb/yr train to produce Dowlex linear low-density polyethylene (LLDPE) in the middle of a sugar cane field in Brazil. Once online, the unit will be the first fully integrated sugar-cane-to-polyethylene complex in the world, according to the company. In the process, sugarcane juice is fermented, centrifuged and distilled to produce ethanol, which is then converted into...*_4843.html

In late 2009, Microbia PE, Inc. (Lexington, Mass.; will begin commercialization of its initial carotenoid products. Microbia plans to produce β-carotene, astaxanthin, zeaxanthin, cathaxanthin and lutein — all five carotenoid products that currently have significant commercial value. These carotenoids have primary applications as food ingredients, dietary supplements and...

Azotobacter are nitrogen-fixing bacteria that do a useful job in soil by converting N 2 to ammonia. As a side reaction they also produce hydrogen, most of which they oxidize for their own energy consumption. In a project of the U.S. Dept. of Agriculture’s Soybean and Nitrogen Fixation Unit (USDA; and North Carolina State University (Raleigh, N.C.), scientists have...

Scientists from CSIRO (Melbourne, Australia; have succeeded in engineering the model plant Arabidopsis to produce 30 wt.% of vernolic acid, an unusual fatty acid (UFA), in its seed oil. The project’s leader, Allan Green — who presented the findings at the Fifth Annual World Congress on Industrial Biotechnology & Bioprocessing (Chicago, April 27 – 30) —...

Soy-oil-based hydrogels developed by the U.S. Agricultural Research Service (ARS) show promise as biodegradable encapsulants for drug delivery. Scientists at ARS’ National Center for Agricultural Utilization Research (Peoria, Ill.; have collaborated with researchers at the University of Toronto to encapsulate the breast-cancer drug doxorubicin in hydrogel nanoparticles. In...

  While it may be one of the oldest chemical processes known to mankind, fermentation is getting a high-tech face lift as industrial biotech firms put a fresh spin on the age-old technology in an effort to develop advanced products in a more environmentally friendly and less costly way. "The technology is generally the same — using microbial systems and metabolic fermentation — but by...
