An enzyme made by bacteria living on seaweed is being used to make environmentally friendly laundry detergents. Scientists studied how bacteria release themselves from seaweed by using an enzyme called phosphodiesterase, which breaks down the sticky molecules naturally present on its surface. More ways bacteria help us: Newcastle University experts have developed its potential for use as a new type of natural cleaner which could be used to wash clothes. They found that the enzyme could work at higher temperatures, but was at its best in lower ones, as in the sea. The team, led by Professor Grant Burgess in collaboration with Dr Michael Hall , worked with Procter & Gamble (P&G) to show it could work in modern laundry detergents which are designed for lower temperature washes, that are more environmentally friendly. The team behind the research were led by Dr Mike Hall (left) and Professor Grant Burgess (right) © Newcastle University/PA Dr Hall, senior lecturer in organic and biological chemistry, said: “Phosphodiesterases are found everywhere – they are even naturally present on your skin. “But what was so exciting about this phosphodiesterase was its resilience. “Most enzymes are quite fragile and are damaged by high temperatures, but […]
