Bacteria found in Britain can 'eat' plastic enzyme found in Britain can 'eat' plastic bacterial enzymes
natural counterpart of the British researchers investigating plastic, accidentally discovered the can 'eat' bacterial enzyme decomposition plastic - — “PETase”。
according to 70% of all soft drinks, fruit juice and mineral water are made from PET bottle packaging sales, this caused a lot of pressure to environmental protection - — Abandoned PET before their degradation in the environment for hundreds of years.
this week, the university of Portsmouth, said John McGeehan use called PETase natural enzymes 'digest' plastic containers. When the molecular structure of the detection of bacteria, the British team inadvertently created a powerful new version of the protein.
the findings have been published in the journal proceedings of the national academy of sciences.
but before PETase actual delivery, there are a lot of research needs to be done. The improved version of a litre of enzyme solution can decompose a few milligrams daily plastic, as a result, the researchers need to further improve its ability of plastic digestion.
'although improve much, but the unexpected findings suggest that there is still room for further improvement of these enzymes, we are expected to launch decomposition plastic waste recycling solution of mountains. '
' the technology exists, the next few years we will see a feasible in industrial process, PET and other potential (can be Plastic) Base material back to its original structure, the basis of which enabled them to a sustainable recovery. '
Portsmouth scientists working with American colleagues, diamond light source in Oxfordshire ha will synchrotron factory intense X-ray beams on bacteria.
around the circular tunnel to accelerate electrons X-ray than in facilities department sun shine 10 billion times. X ray can be used to reveal the fine structure of materials and biological molecules until the level of a single atom.
scientists to design the molecular, lead to mutation protein have enhanced plastic attack and decomposition capability.
in addition to digest the PET, new enzymes can degrade poly furan dicarboxylic acid ester ( polyethylene furandicarboxylate） , this kind of plastic has been hailed as a substitute for glass beer bottles.
'we are to deal with the problem of plastic play an important role, but in the end, to create the 'magic materials science now must use all the existing technology to develop the real solution. 'Conversion table packaging printing knowledge
