Dyadic Joins Dutch Sugar Beet Pulp and Wheat Bran Ethanol Research Projects

Dyadic International, a biotechnology company, has joined Royal Nedalco and other partners in R&D projects funded by the Netherlands government to develop technologies to produce ethanol from sugar beet pulp and wheat bran. Dyadic Nederland BV, Dyadic’s subsidiary in Zeist, the Netherlands, will focus on the development of optimal enzyme preparations for the extraction of sugars from these feedstocks.

Funding for the projects will be provided by grants from the Ministry of Economic Affairs in the Netherlands, in the Energy Research Program EOS, managed by SenterNovem.

Sugar beet pulp, with its currently low value, high volume at centralized locations and abundant carbohydrate content, is an attractive feedstock for the production of bioethanol. Wheat bran, a byproduct of wheat processing, is another attractive bioethanol feedstock. However, the enzyme preparations to economically extract sugars from these materials and the yeasts required to ferment these unusual sugars for large-scale ethanol production need to be further developed. Our research projects are designed to overcome these technical problems and contribute to the development of economically viable renewable fuels for the future.

—Jan Verdoes, Ph.D., Research Director, Dyadic Nederland BV

In addition to Dyadic Nederland BV, the four-year sugar beet pulp collaboration will include Wageningen University for characterization of enzyme-treated substrates, Delft University for yeast fermentation engineering, the Energy Research Center of the Netherlands for process modeling and economics, and Royal Nedalco for commercial testing of the process.

For the two-year wheat bran collaboration, Dyadic joins Wageningen University for characterization of plant cell wall polysaccharides, BIRD Engineering for fermentation technology, and Royal Nedalco for commercial process testing. Royal Nedalco, a leading European producer of bioethanol, is a subsidiary of Cosun, a producer of natural ingredients and foodstuffs for the international food industry with annual revenue of approximately €1.3 billion (US$1.7 billion).

Dyadic developed an integrated technology platform to rapidly discover and express genes of both eukaryotic and prokaryotic origin, then efficiently and inexpensively manufacturing the products of those genes. The company uses a number of proprietary fungal strains to produce enzymes and other biomaterials, principally focused on a system for protein production based on the patented Chrysosporium lucknowense fungus, known as C1.

Dyadic is applying its technologies to produce enzymes for use in converting various agricultural products (e.g. corn) and waste products (e.g. switch grass, wheat straw, sugar cane bagasse, etc.) into fermentable sugars, which can then be used in the production of traditional and cellulosic ethanol as well as other products currently derived from petroleum.

In October 2006, Dyadic signed a three-year research and development (R&D) agreement and a $10-million stock purchase agreement with Abengoa Bioenergy R&D (ABRD). That R&D agreement has as its objective the development of a cost-effective enzyme production system for commercial application in Abengoa Bioenergy’s cellulosic ethanol production process.

Royal Nedalco earlier signed a joint development agreement with SunOpta under which SunOpta will license Nedalco’s patented pentose fermenting yeast for the production of cellulosic ethanol in North America. Furthermore, SunOpta will work with Nedalco to include SunOpta’s technology and systems for cellulosic ethanol production into their planned new grain ethanol facilities in Europe.

A consortium including Nedalco, Delft University of Technology and BIRD Engineering—all located in the Netherlands—developed a patented and novel pentose fermenting yeast that is capable of high conversions of pentose sugars as well as the hexose sugars into cellulosic ethanol at high yields.

Utilization of livestck/agri/forestry waste/byproducts will be one of the points of concentration in the "Green Revolution".

_Sugar beet pulp is usually fed to (large) livestock, and the same goes for some of the wheat bran. This might have a similar dymanic to what will happen if we gasifying DDG. These are not primary animal feeds, but it will have an impact on the price of meat, and other foods.

Rafael Seidl

Sugar beets were a highly subsidized crop in Europe until the WTO upheld a complaint that ended the bonanza. Unsurprisingly, Europe's sugar barons are now looking for new ways (preferably also subsidized) to turn their beets into marketable commodities. Ethanol fetches a higher price than cattle feed.

In general, the European agricultural market is so riddled with red tape and subsidies that normal market forces virtually don't apply any longer. Livestock is ferried between member states for various processing steps, allowing their owners to collect "export" subsidies each time this happens. Surplus meat is then dumped on African markets, sometimes with yet more export subsidies. European farmers are virtually state employees, earning as much as 80% of their income from subsidies.

Then we get religion and limit CO2 emissions by cars because of global warming, while each year rainforest acreage the size of Belgium is clear-cut and burnt to grow soy beans for export to Europe as - you guessed it: cattle feed. The lunatics really are running the asylum.

Rumor has it French (and presumably, other) political parties receive plenty of campaign cash from European agrobusiness and food giants that take most of what is handed to farmers in the form of higher prices for seeds and machinery and lower ones for produce.

My personal hope is that the most recent round of enlargement to 27 member states has finally broken the EU institutions so badly that the moribund EU constitution has to be renegotiated from scratch and agriculture no longer consumes half the EU budget. However, many EU bureaucrats, EU parliamentarians plus the France and a few other member states will fiercely resist any cuts in farm subsidies, so quite a few pigs will have fly first.


Pretty grim picture.

h korin

thanks soo much to you & ur teamwork ,,
please i need detaled information about sugar beets indusries,
thank you very much



For Pentose fermentation are you going to use :

1. Co Fermentation?
2. Modified C6 yeast?

really i send my thanking to u ,, and can i ask please ..
are you haveany branch or company in EGYPT ,work in field of sugar beets or sugar cann ??
because iam very interest to work at that fiel in egypt
thaku you very much ..
