Polysaccharide molecules such as cellulose, seen here, are long chains of sugars that are very hard to break apart. Enzymes – proteins that can degrade polysaccharides – have many industrial uses.
Bio-prospecting is the search for useful materials from natural sources. A biologist explains what we can learn from bacteria about breaking down plant material, and how we can use that knowledge.
Ingredients from shampoo, sunscreens and other personal care products are turning up in water supplies. Some are toxic or cause hormonal damage to aquatic life, and could threaten human health.
