    摘要: Refining elements are disclosed for use in refiners in which the refining elements comprise a refining surface with a plurality of raised bars alternating with a plurality of grooves. The raised bars at the inlet of the refining path have a first spacing and form a first angle with respect to a radius or generatrix defining the refining path and the plurality of raised bars at the outlet of the refining path have a second spacing and form a second angle with respect to the radius or generatrix, the first angle being between about 50.degree. and 85.degree. and the second angle being between about -25.degree. and +25.degree., and the first spacing being greater than the second spacing.

    摘要: A method for producing a mutant gene encoding a functional gene product comprising: (a) introducing one or more mutations into a gene to form a mutated gene; (b) providing the mutated gene to a host microorganism; (c) culturing the host microorganism containing the mutated gene under conditions which allow expression of the mutant gene product; and (d) selecting a host microorganism capable of producing a functional gene production from the mutated gene.
