How Mushrooms Battle Dirty Laundry

The New York Times: Scientists from a “Danish biotechnology company … Novozymes, regularly trudge through the mud, hunting for oyster mushrooms that protrude from a fallen beech or bracken fungi that feast on tough plant fibers. They are studying the enzymes in mushrooms that speed up chemical reactions or natural processes like decay … Their work is helping the company develop enzymes for laundry and dishwasher detergents that would require less water, or that would work just as effectively at lower temperatures.”

“Enlisting enzymes to battle dirt is not a new strategy. Over thousands of years, mushrooms and their fungi cousins have evolved into masters at nourishing themselves on dying trees, fallen branches and other materials. They break down these difficult materials by secreting enzymes into their hosts. Even before anyone knew what enzymes were, they were used in brewing and cheese making, among other activities.”

“Novozymes and its rivals have developed a catalog of enzymes over the years, supplying them to consumer goods giants like Unilever and Procter & Gamble … In 2009, Novozymes scientists teamed up with Procter & Gamble to develop an enzyme that could be used in liquid detergents for cold-water washes.” Phil Souter of P&G comments: “We knew this was something that consumers would want. I think this is a very tangible and practical way people can make a difference in their everyday lives.”
