Companies Developing Modified Plant Varieties as Improved Biofuel Feedstocks

Earlier this year, I completed several blog entries that provided brief profiles of companies developing modified microorganisms, plants or algae for improved biofuel production. The field has, of course, continued to develop in the several months since those entries, and not only have the originally-profiled companies announced new business and scientific developments, but other companies have announced their presence or have otherwise come to my attention. In view of the dozens of companies profiled in the earlier entries, it really isn’t feasible to continually update their profiles, particularly since links to company websites are included in each profile, but in this and the next several entries I will profile some of the additional companies that have entered the field or whose activities I’ve recently learned about.

Today’s posting will focus on companies developing modified plant varieties for use as biofuel feedstocks. This is a topic I may revisit in the blog in the coming months, because I have been asked to chair a session on “Energy Crops” at the 2011 World Biofuels Market Conference in Rotterdam in March. So far it is shaping up as a diverse, interesting set of presentations, and for my own talk, I’m planning to present an overview of the plant biotechnology strategies that are being used to improve energy feedstocks.  I welcome comments and suggestions about this topic in the months leading up to the March 22, 2011 session.

A large number of companies are using advanced biotechnology to improve the plant varieties that are, or might be, used as feedstocks to produce renewable fuels like ethanol or biodiesel. Many of these companies were profiled in a series of earlier blog entries, beginning at http://wp.me/pKTxe-1p.  The following are profiles of additional companies in this sector. The profiles have been adapted or excerpted from company websites and/or other publicly available information, and I don’t assume any liability for the accuracy, comprehensiveness or use of the information.

Abba Gaia is a Spanish company formed on April 2, 2008 to use biotechnology to help improve the environment.  Abba Gaia’s main business is using Nicotiana glauca for phytoremediation, and has R&D programs directed at genetic engineering to improve the plant’s ability to remove heavy metals and other contaminants from soil, water and sludge. According to the company’s website it is active in several other industrial sectors, including “renewable energy”, but the website offers no specifics about activities in the energy sector. However, in 2010, in a notification submitted to the EU, the company proposed a field test in Spain of Nicotiana glauca genetically modified as an energy crop (Notification B/ES/10/50, Spain, published 24 June 2010). According to this notification, the genetic material inserted into Nicotiana glauca is the wheat phytochelatin synthase gene under the control of the 35S promoter of cauliflower mosaic virus, to provide phytochelatin synthase and phytochelatins overexpression in the plant, along with a gene conferring resistance to the antibiotic kanamycin for selection of transformed plants. The goal of this field test is to evaluate the genetically modified line for biomass production under different cultivation situations .

Catchlight Energy is a joint venture between Chevron and Weyerhaeuser, formed in February 2008 to commercialize large scale production of liquid transportation fuels from sustainable forest-based resources. The plan was to leverage the strengths of both companies: Weyerhaeuser’s expertise in innovative land stewardship, resource management and capacity to deliver sustainable cellulose-based feedstocks at scale, and Chevron’s technology capabilities in molecular conversion, product engineering, advanced fuel manufacturing and fuels distribution. The joint venture reflects the parent companies’ shared view that cellulosic biofuels can fill an important role in diversifying the nation’s energy sources and addressing global climate change by providing a source of low-carbon transportation fuel.

Catchlight Energy’s vision is to become a major integrated producer of biofuels derived from non-food sources and to deliver renewable transportation products produced from biomass in a manner that is scalable and sustainable — both environmentally and economically. By focusing on researching and commercializing technology, Catchlight Energy hopes to help the U.S. make the move to the next generation of biofuels. The company’s research addresses a range of products including ethanol as well as gasoline and diesel hydrocarbons, and its commercial business model is expected to involve multiple pathways based on combinations of biological, chemical and thermochemical process steps.

Building on the strengths and core competencies of its parent companies, Catchlight’s R&D program is aimed at discovering, developing and/or licensing third party developed technology solutions for converting forest-based feedstocks to liquid transportation fuels. This strategy will likely involve cooperation with key technology partners having complementary interests and technology. The company says there are two main thrusts to its current research efforts: a near term focus on early commercialization opportunities for producing ethanol and a longer term focus on direct conversion of biomass to hydrocarbons. While there is a large and ready market for ethanol today, the company thinks it will be important for longer term success to expand its product portfolio to include hydrocarbons like gasoline and diesel, fuels that are fully compatible with the existing infrastructure.

Catchlight Energy intends to utilize the potential of forests to produce biomass in a sustainable manner while still maintaining supply for traditional forest products. Specifically, perennials, short rotation trees, understory crops and residuals to supplement high-value timber can be used for emerging biofuels markets, and such purpose-grown energy crops can be grown in conjunction with high-value timber. The plan is to grow alternating strips of trees and energy crops. The energy crops can be harvested annually while the trees are managed for wood products and fiber. The company will develop large-scale production capability by leveraging Weyerhaeuser’s strengths in managing large-scale ecosystems, its experience with harvest, handling and transport infrastructure, and its expertise in genetic improvement (e.g. to improve yield, product quality). The company will also aim to scale up their processes so that cellulosic ethanol can be produced in a manner that is scalable and sustainable — both environmentally and economically. In this regard, the company will capitalize on Weyerhaeuser’s vast land holdings, Chevron’s large fuel infrastructure, and the development of a cost-effective end-to-end business model, to enable the company to produce significant quantities of cellulosic biofuels.

Idén Biotechnology was founded in 2005 by members of the Carbohydrate Metabolism Research Group at the Agrobiotechnology Institute of the Spanish National Research Council. The company’s goal has been the generation, transfer, exploitation and marketing of innovative agricultural biotechnology knowledge. The company’s founding scientific team has expertise in plant and bacterial carbohydrate metabolism knowledge at a physiological, biochemical and molecular level, and have used this expertise to develop new industrial raw materials which the company says are applicable to the energy, paper, biomaterials and pharmaceutical sectors. Specific areas of research focus as the development of new plant-derived raw materials based on manipulation of carbohydrate metabolism, with applications in bioenergy, food, feed and biomaterials, or through modifications in secondary metabolism to address markets including agriculture, food, feed and biomaterials.

Among the company’s activities in the energy sector, Iden submitted a notification to EU regulatory authorities for a field test in Spain of maize plants engineered for modified lignification with the goal of improving digestibility for bioethanol production. According to Notification  B/ES/10/40, published 23 March 2010, the company planned a small field test of corn in which the gene encoding cinnamyl alcohol dehydrogenase (CAD), an enzyme which is involved in lignin production in the plant, was knocked down using RNA interference. In CAD-RNAi expressing plants, the enzyme CAD was shown to be inactivated. In greenhouse experiments, CAD-RNAi expressing plants showed altered lignin production and an increase in degradability for the production of ethanol in vitro as compared with wild type corn plants. The company hopes that field tests will establish that residual biomass of these plants could be of great agronomic value for more efficient ethanol fermentation.

Naturally Scientific plans to use waste CO2 to bio-manufacture fermentable sugars and pure vegetable oil from plant cell cultures to provide sustainable feedstock for bio-diesel, ethanol and “drop-in” synthetic fuel producers. In April 2010, Naturally Scientific CEO Geoff Dixon said that his company had signed its first five commercial installations, a series of five $50 million projects that would be erected in China over the next five years. In May 2010, the company announced further details about its patented solution for converting waste CO2, water and light in a photosynthetic reaction to grow palisade layer plant cell culture to produce low-cost sugar – glucose and sucrose. This natural sugar can be sold in crystallized or concentrated liquid syrup form or alternatively it is used in a second process as the necessary carbon source for vacuole cells of rapeseed (or other oil seeds) to produce pure vegetable oils and their valuable derivatives. Naturally Scientific says that its technology absorbs and fixes between 90% and 100% of the CO2 passed through it, and in using plant cell cultures, the resulting products can be produced in a safe and sustainable way that results in no indirect land use change or deforestation. Naturally Scientific has constructed a demonstration plant in Nottingham, UK which it expected to be fully operational by the end of May 2010, producing both sugars and oils. The plant is a scaled down version of a 500,000 gallon plant proving the technology, automated process control systems, yields and unit economics at commercial-scale. The company is planning a business model based on out-licensing its technology to other companies.
