Full-length papers cited (see Reference section) can give further details on the processes mentioned in this chapter. Review papers on various topics within the subject may be found similarly useful (e.g. Doi, 1992; Naidu and Panda, 1998; Kim et al., 2003). Relevant journals include Process Biochemistry, Bioresource Technology and Applied Microbiology and Biotechnology. The suppliers of the enzymes, microorganisms are in general reliable sources of relevant information. They usually have feedback data and extensive knowledge on the bio-processes. Some of the major commercial suppliers are: Calbiochem-Novabiochem, USA (www. calbiochem.com); Novozymes, Denmark (www.novozymes.com); Amano Pharmaceutical, Japan (www.amano-enzyme.co.jp). More information on the behaviour of enzymes can be found in various databases, for example:
• BRENDA (www.brenda.uni-koeln.de);
• ENZYME (www.expasy.ch/enzyme);
• Protein Data Bank (www.pdb.org);
• Enzyme Structure (www.biochem.ucl.ac.uk/bsm/enzymes);
• LIGAND (www.genome.ad.jp/dbget/ligand.html).
A complete list of enzyme suppliers and databases was published recently in the journal Biotechnology Advances (Krishna, 2002).
Technical and other opportunities for biocatalytic methods of waste management and co-product recovery in the food industry have been regularly surveyed by the Food and Agriculture Organization (FAO) and some of results are published. For example, Rolle (2005) summarised the possibilities for these technologies in developing countries. Thus, readers are advised to consult the FAO website (www.fao.org/ag).
