    Bioenergy and

    Industrial Biotechnology

  • “Industrial Biotechnology (IB) is a set of cross-disciplinary technologies that

    use biological resources for producing and processing materials and chemicals

    for non-food applications. These resources can be derived from the tissues,

    enzymes and genes of plants, algae, marine life, fungi and micro-organisms.”

    “Bioenergy is a renewable form of energy generated from materials derived from

    biological sources. Bioenergy is increasingly being recognised as having an

    important role in helping the UK to maintain its energy security in the context of

    diminishing worldwide stocks of fossil fuels.”

    and has a digestive tract

    devoid of microbial life.

  • Blue biotechnology is a term that has been used to describe the

    marine applications of biotechnology.

    Green biotechnology is biotechnology applied to agricultural

    processes.

    Red biotechnology is applied to medical processes, e.g. design of

    organisms to produce antibiotics.

    White biotechnology, also known as industrial biotechnology is

    biotechnology applied to industrial processes. An example is the

    designing of an organism to produce a useful chemical…or the

    using of enzymes as industrial catalysts.

    the carbon source. Second trial was run for three weeks with improved operating

    conditions compared to the first trail, which was only run for two weeks.
