(EN) PREPARATION EXHIBITING ENZYMATIC DELIGNIFICATION ACTIVITY, A METHOD OF PRODUCING THE SAME, AND APPLICATIONS THEREOF
Abrégé
(EN) A preparation exhibiting enzymatic activity and havin the capability of delignifying wood pulp at a temperature of at least 65°C and a pH of at least 9, is described. Said pre paration is obtainable by aerobic fermentation of a Bac i 1 lus s ea r othermophi lus strain selected from the deposited strain NCIMB 40221 and NCIMB 40222 and mutants and variants thereof Also, the deposited strains NCIMB 40221 and NCIMB 40222 and mutants and variants thereof are comprised by the invention.

Further, a method of producing said preparation and a process comprising treatment of wood pulp with said preparation, are disclosed. Moreover, the invention
comprises applications of said
preparation as wood pulp and fluff pulp treated with said preparation, and paper, board and fluff made from a wood pul treated with said preparation. Additionally, DNA
and RNA probes which recognize the
nucleotide sequence coding for a specified amino acid sequence, and also an antibody which binds to said amino acid sequence are included.
