The pharmaceutical NANA is 50 times more expensive than gold. Now it can be produced from chitin - a very cheap natural resource. The process was made possible by genetically modifying mold fungi.
Usually, mould fungi are nothing to cheer about – but now they can be used as "chemical factories". Scientists at the Vienna University of Technology have succeeded in introducing bacterial genes into the fungus Trichoderma, so that the fungus can now produce important chemicals for the pharmaceutical industry.The raw material used by the fungus is abundant - it is chitin, which makes up the shells of crustaceans.
