Production of poly(l-lactide)-degrading enzyme by Amycolatopsis orientalis for biological recycling of poly(l-lactide)

  title={Production of poly(l-lactide)-degrading enzyme by Amycolatopsis orientalis for biological recycling of poly(l-lactide)},
  author={Amnat Jarerat and Yutaka Tokiwa and Hideo Tanaka},
  journal={Applied Microbiology and Biotechnology},
Efficient production of poly(l-lactide)(PLA)-degrading enzyme was achieved by addition of 0.1% (w/v) silk fibroin powder into a liquid culture medium of an actinomycete, Amycolatopsis orientalis, without other complex nitrogen sources, such as yeast extract and peptone. Scaled-up production of the enzyme in a 5-l jar fermenter showed the possibility of producing this enzyme on an industrial scale at low production cost. The extracellular PLA-degrading enzyme showed potent degrading activity… CONTINUE READING
