Title:
ALGINATE LYASE PRODUCING STRAIN AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/078140
Kind Code:
A1
Abstract:
The present invention relates to the technical field of microorganisms, and provides an alginate lyase producing strain HB171785. The strain belongs to γ-proteobacteria genus Neiella, the accession number is GDMCC No.61001, and alginate lyase produced by the strain has good temperature stability. Also provided are alginate lyase and a preparation method therefor. The strain HB171785 and the alginate lyase have application potential in degradation of algin and preparation of alginate oligosaccharides.
