In a first aspect, the present invention relates to a recombinant fungal strain, capable of expressing chitin deacetylase, comprising an expression vector that contains a nucleic acid molecule encoding chitin deacetylase, a suitable promoter and a transcription terminator. In particular, the present invention provides a recombinant Aspergillus oryzae strain capable of expressing chitin deacetylase obtained from Mucor rouxii. The present invention also relates to a method for producing chitin deacetylase by a recombinant fungal strain. In a second aspect, the present invention relates to a recombinant yeast strain, capable of expressing chitin deacetylase, comprising an expression vector that contains a nucleic acid molecule encoding chitin deacetylase, a suitable promoter and a transcription terminator. In particular, the present invention provides a recombinant Pichia pastoris strain capable of expressing chitin deacetylase obtained from Mucor rouxii. The present invention also relates to a method for producing chitin deacetylase by a recombinant yeast strain. The present invention further relates to purified recombinant chitin deacetylase enzyme. |
