The chemical is an enzyme, one of a class of molecules that speed many of the chemical processes associated with organic life.- In this case, it breaks down cellulose into glucose, a sugar that sweetens honey and fruits. And, since cellulose accounts for most farm and city wastes, this could open up a major new source of sugar. Glucose can be used directly as food for man and animals. It can be fermented into ethanol, a fuel, or into antibiotics Altei natively, microbes such yeast can eat glucose and the proteins they produce can be used for animal feed and, possibly, food for man The chief use of the converted cellulose will be as fuel or as a chemical feedstock, says Dr. Mary Mandels, who heads the pioneering enzymatic conversion project at the U S Army Natick Laboratories in Natick, Mass. "You could mix about Nixon castigated over Europe claim BRUSSELS (Reuter) Eu- ropean Common Market diplo- matic sources have angrily re- jected U.S. President Nixon's charges that the nine commu- nity countries are refusing to co-operate politically and eco- nomically with the United States. They described Nixon's re- marks in Chicago Friday as "counter-productive" and "hypocritical." One official of the Market's executive commission, the community's policy-forming organ, said privately Saturday that the president cast doubts on his sanity by using "wild language and threats." Nixon indicated he may can- cel his proposed trip to Brussels next month because there has been insufficient progress on a joint U.S. Common Market declaration of principles which he was expected to sign in the Bel- gian capital. The president also raised the threat of U S troop withdrawals from Europe unless the Europeans begin to co-operate with the United States on the political and economic fronts. The Market sources here said it was the U.S. which cancelled a scheduled meeting in Bonn last week between high U.S and Common Market officials who were to have discussed the declaration of principles. U.S. State Secretary Henry Kissinger was given a copy of the European draft of the dec- laration March 4 when he vis- ited here. One Market source said: "If the Americans do not like it, it would have been nice if they had told us about it in a more diplomatic way than by this outburst in front of television cameras Market foreign ministers of the nine accepted the declara- tion just hours before Kissinger arrived here. They also agreed to start formal Market consultation with Arab countries on economic and other forms of co- operation. 17 percent of clean-burning ethanol with gasoline without even changing the she explains. Dr. Mandels and the now retired Dr. Elwyn Reese discovered the usefull fungus (Tnchoderma viride) in They then developed a more effective mutant strain by irradiating the wild fungus with high-energy electrons, and further concentrating it by ultrafiltration. The resultant enzyme, called celluiase, can be used to break down a wide range of materials- plastic-coated boxes, and dacron and nylon and cotton-blended fabrics, as well as waste cellulose in the form of newspapers, cardboard, paper- mill waste, rice hills, and bagasse-plant residue left after a product has been extracted. Until recently, such enzymatic breakdown of ceiiuiose was slow and inefficient. Now, despite some imperfections in the process, at least 50 percent conversion of waste cellulose has been demonstrated within a 12-hour period Dr Mandels and her co-researcher physicist John Kostick, are about to set up a small pilot plant to convert as much as 100 pounds of waste-most likely newspaper and other paper products-into 50 pounds of glucose a day. The plant, which could be operating by April, would be the only one of its kind, says Mr. .Kostick. But the pilot plant, which could require worth of equipment, will still be a long way from a from a profit- making enterprise. It would need to convert at least 100 tons of waste paper a day to make money, says two enzymo- logists studying cellulose conversion. In the process of converting newspaper to glucose, a residue of the moncellulosic materials such as ink in the newspaper, is formed It can be cast into building blocks, electrical components, patios, and walkways, Mr Kostick explains. If Natick's pilot plant works well, the Army might set up a full-scale waste-conversion plant at a site producing large amounts of cellulose waste Dr Leo Spano, who supervises Dr. Mandels's research, says he is trying to persuade the Atomic Energy Commission and the National Science Foundation to pay for half the cost of such a plant.
