(EN) PHYTASE MUTANT
(FR) MUTANT DE PHYTASE
(ZH) 植酸酶突变体
Abstract
(EN)
The present invention relates to the biotechnology field, and particularly relates to a phytase mutant, a preparation method and the use thereof, a DNA molecule encoding the phytase mutant, a vector and host cells. The heat resistance of the mutant provided is significantly improved, and it is thus beneficial for the phytase to be widely used in feed.
(FR)
La présente invention concerne le domaine de la biotechnologie, et concerne en particulier un mutant de phytase, un procédé de préparation et son utilisation, une molécule d'ADN codant pour le mutant de phytase, un vecteur et des cellules hôtes. La résistance à la chaleur du mutant de l'invention est considérablement améliorée, et il est bénéfique d'utiliser largement la phytase dans l'alimentation.
