Abstract
A new thermotolerant Actinomadura sp., which is capable of degrading polyesters, is provided. Compositions comprising the species for use in degrading polyesters are also provided. The invention also relates to methods for degrading polyesters by using the strain and the composition.
Claims31
An isolated Actinomadura sp. capable of degrading polyesters, said Actinomadura sp. comprises:
- short spores chain on the tips of aerial mycelium;
- non-motile and rod spores with a spiny surface;
- blue aerial spore mass;
- an absence of soluble pigment production;
- an ability to grow at about 25° C. to 55° C.;
- an ability to hydrolyse casein, aesculin and L-tyrosine;
- an ability to produce nitrate reductase;
- an ability utilize glucose, xylose, rhamnose, sorbitol, fructose, trehalose and lactose;
- and
- a DNA-DNA hybridization rate with Actinomadura miaoliensis BC44T-5 of at least 70%, wherein Actinomadura miaoliensis BC44T-5 is deposited with the ATCC under the accession number PTA-8409.
A composition comprising a microorganism selected from the group consisting of Actinomadura nitritigenes, Actinomadura rubrobrunea, Actinomadura rugatobispora, and a combination thereof.
A method for degrading polyesters comprising the step of contacting a polyester with a microorganism selected from the group consisting of Actinomadura nitritigenes, Actinomadura rubrobrunea, Actinomadura rugatobispora, and a combination thereof.
