1. 1. Converting Poultry Feather Waste into Bioplastics using Green Modifying Agents

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Marc Jirström; [2021]
   Keywords : polymer technology; materials science; renewable materials; Technology and Engineering;

   Abstract : Handling of problematic waste material, and the use of fossil-based and non-biodegradable plastics are two major sustainability challenges. By developing solutions that convert waste material to bioplastics, it is possible to address both these issues. READ MORE

3. 2. 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.
