| Abstract: |
A strain producing chitin deacetylase (CDA) was isolated and identified as Rhodococcus erythropolis by morphological characteristics and 16S rDNA analysis, named as R. erythropolis HG05. By Plackett-Burman and central composite design, CDA production from R. erythropolis HG05 was increased from 58.00 U/mL to 238.89 U/mL. With the crude enzyme from R. erythropolis HG05, the hydrolysate components from colloid chitin were chito-oligosaccharides with polymerization number larger than hexaose. (C) 2013 Elsevier Ltd.
