  1. 6. 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.

  3. 7. Robust Encapsulation of Yeast for Bioethanol Production

    University essay from Högskolan i Borås/Institutionen Ingenjörshögskolan

    Author : Sainath Namthabad; Ramesh Chinta; [2014]
    Keywords : Microencapsulation; Cell immobilization; Entrapment; Biomineralization; Genipin; Bioethanol; Lignocellulosic hydrolyzates;

    Abstract : In the future the demand for ethanol is expected to increase greatly due to the rising energy requirements in the world. Lignocellulosic materials are a suitable and potentially cheap feedstock for sustainable production of fuel ethanol, since vast quantities of agricultural and forest residues are available in many countries.

  4. 8. E-procurement adoption, its benefits and costs

    University essay from Högskolan i Borås/Institutionen Ingenjörshögskolan

    Author : Hossein Mahdillou; Jawid Akbary; [2014]
    Keywords : E-procurement; Supply chain management; ERP; Direct cost DIR ; Strategic Purchasing Cost SPC ; Operational Purchasing Cost OPC ; Non Product Related NPR ; Cost Benefits CB ; Electronic Procurement System EPS ;

    Abstract : This thesis report aims at illustrating and describing how e-procurement can contribute in creating value and reducing overheads associated with the procurement process through adopting and implementing e-procurement systems and applications in the supply chain network of an organization. It is an obvious fact that e-procurement plays a vital role in managing the supply chain especially now that outsourcing has become very common in the business market environment around the world.

  5. 9. Rapid Bio-methanation of Syngas by High Cell-density in Reverse Membrane Bioreactors

    University essay from Högskolan i Borås/Institutionen Ingenjörshögskolan

    Author : Konstantinos Chandolias; [2014]
    Keywords : syngas; fermentation; reverse; membrane; bioreactor; bio-methanation; high cell density;

    Abstract : Syngas fermentation via gasification is a two-stage process, which contains gasification of feedstock into syngas and syngas bio-methanation by anaerobic microorganisms. This project is a study on syngas fermentation. The gasification feedstock can be difficult-to-degrade solid waste so; waste volumes are reduced while green energy is produced. READ MORE

  6. 10. Design and Construction of a Small-Scale Fixed-Bed Reactor

    University essay from Högskolan i Borås/Institutionen Ingenjörshögskolan

    Author : Akhator Peter E.; [2014]
    Keywords : Fixed-bed reactor; ; gasification; pyrolysis;

    Abstract : As biomass and municipal solid wastes become increasingly viable fossil fuels alternatives, more researches are being conducted to improve on the processes for their conversion to energy or energy carriers. Gasification is one of such processes and it forms the core of this project. READ MORE
