Hey pplz, i have a biopolymers assignment to do, that is research a biopolymer. If someone's done this assignment. PLZ POST IT UP
THANKUUUUU

/me rummages through notes

Polymer: Polylacticacid (PLA)

Monomer: Lactic acid

Bacteria used: Alcaligenes eutrophus

Process: The bacteria can be fed starch, and the lactic acid monomers are produced by the bacterial digestion of starch waste. The lactic acid can then be converted to the PLA polymer by solvent-free polymerisation.

Properties: Strong, flexible and biodegradable

Potential uses: Disposable (biodegradable) plastics, medical implants, agricultural mulch films

Research: This biopolymer was first developed in the 1980s. In 1997 in Japan a PLA/polyester copolymer film was developed. Current areas of research are into better bacteria and making the process more economically viable through catalysts.

theres a thread on this already somewhere, there were a few replies to it...

Alcaligene eutrohpus also makes polyhydroxybutanoate

thanxx calculon, phb is too common kimmeh, but thanxx neways.

The textbook by Irwin Farrelly, Garnett and someone has a reasonable amount on polylactic acid.

So does pathways, thats where I got my info from

kimmeh ur dog is so cute.
so does that Alcaligenes eutrophus thing really work on ploy lactic
acid as well as PHB
lets hope it does coz i'll gunna use it if it comes up in my trial tomorrow

uhhh, not up to studying that yet, but i did cyclodextrins
