  1. 1. Optimization of growth conditions for a recombinant keratinase producing bacterial strain

    University essay from Högskolan i Borås/Institutionen Ingenjörshögskolan

    Author : Kristina Laurila; [2014]
    Keywords : Keratinase; chicken feathers; growth; Bacillus megaterium;

    Abstract : A recombinant Bacillus megaterium strain with a chromosomally integrated gene kerA, expressing keratinase, was analyzed regarding action in specific environmental stresses to obtain optimum parameters necessary for bacterial growth and optimal expression of the recombinant gene.The strain was grown on chicken feathers as substrate and the degradation of feather keratin during the growth was investigated with different levels of pH, temperature and feather concentration in the broth.
