  • Making stuff using microbes and enzymes
    • By respiring aerobically in dough, yeast produces carbon dioxide which makes the bread rise
    • Bacteria ferments the lactose sugar in milk to create lactic acid, which makes the protein form a solid - yoghurt
    • The fungus penicillium secretes the antibiotic penicilin, we can grow the fungus in a large fermenter
    • Biological washing powders remove stains in non-protein materials by digesting the food groups and decrease the temperature needed to wash clothing
    • The enzyme pectinase breaks down the natural glue between cells in apples thus making it easier to extract more apple juice
