1. Optimization of growth conditions for a recombinant keratinase producing bacterial strain
Master-uppsats, Högskolan i Borås/Institutionen IngenjörshögskolanSammanfattning : 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.

2. Chromosomal Integration of KerA Gene in Bacillus megaterium For Stable Keratinase Production
Magister-uppsats, Högskolan i Borås/Institutionen IngenjörshögskolanSammanfattning : In order to develop a stable strain of Bacillus megaterium for Keratinase production, the Keratinase gene (KerA) of Bacillus lichiniformis ATCC 53757 and SPlipA gene from plasmid pHIS1525.SPlipA (Bacillus megaterium origin) were PCR amplified and constructed to give a gene cassette called SPK .
