  • Biosafety Guidelines for Contained Use of Genetically Modified Microorganisms at Pilot and Industrial Scales i

    Preface

    Genetically Modified Microorganisms (GMMs) were first used in B.E. 2525 to

    produce insulin in industrial medicine. Currently, GMMs are used in various industries,

    such as the food, pharmaceutical and bioplastic industries, to manufacture a number

    of important consumer products. To ensure operator and environmental safety,

    the Technical Biosafety Committee (TBC) of the National Center for Genetic Engineering

    and Biotechnology (BIOTEC), the National Science and Technology Development Agency

    (NSTDA), has prepared guidelines for GMM work, publishing “Biosafety Guidelines for

    Contained Use of Genetically Modified Microorganisms at Pilot and Industrial Scales”

    in B.E. 2547. The guidelines have been updated every two years to take into account

    the latest information and technology. In B.E. 2558, GMM waste management

    guidelines were added to facilitate operator work, the list of microorganisms/agents

    was updated to conform to lists of national and international organizations, and

    an English version was prepared for foreign organizations/institutions involved in

    GMM work at pilot and industrial scales in Thailand.

    The principle and scope of these guidelines cover the use of GMMs in

    containment at pilot and industrial scales according to GMM classification, together

    with suggested containment levels, GMM waste management, transport, possession,

    emergency plans and the responsibilities of personnel associated with GMM work.

    The committee acknowledges the Biosafety Sub-Committee on Microorganisms

    and the Organizing Committee on Biosafety Guidelines for Contained Use of Genetically

    Modified Microorganism (English version) for their cooperation and revision of these

    guidelines, and Ajinomoto Co., Ltd. for supporting the preliminary translation.

    Finally, the committee hopes that these guidelines will be helpful in promoting

    safe GMM work at pilot and industrial scales. Suggestions and comments on the

    guidelines are most welcome.

    Definitions

    Bacteriophage: An obligate intracellular virus that multiplies inside bacteria.

    Biosafety level: The level of biosafety of work using GMMs by implementation

    of a containment level. In some countries, biosafety level is equivalent to ‘containment

    level’.

    Closed system: A system which separates GMMs from the environment during

    the culturing process, such as a bioreactor or biological safety cabinet (tissue culture

    hood). It also includes production processes utilizing equipment connected in a closed

    system, such as inoculation of GMMs into a bioreactor, and downstream processes

    for product purification, as well as systems where equipment are not connected but

    are set up within a safety enclosure. A closed system used for GMM activities at pilot

    and industrial scales should be routinely checked.

    Contained use: The use of GMMs in a restricted area, isolated from the

    outside environment through the provision of tools and equipment, working space

    and working protocols for the purpose of research or industrial production.

    Containment and containment level: Control of GMMs to a restricted area,

    isolated from the outside environment through the provision of tools and equipment,

    working space and working protocols to facilitate research or industrial production.

    There are 4 containment levels which have been classified according to degree of

    risk in terms of human pathogenicity and potential hazard to the environment.

    Controlled area: An area for conducting GMM work such as inoculation and

    propagation of GMMs in a bioreactor, sampling or transport of GMMs, and

    downstream processes such as the purification of GMM products.

    Donor organism: A living organism that is the origin of the DNA or gene

    inserted into a host cell for a desired phenotype.

  • viii Biosafety Guidelines for Contained Use of Genetically Modified Microorganisms at Pilot and Industrial Scales

    Genetic modification technique:

    1. The use of recombinant DNA technology to ligate DNA fragments or

    heterologous genes of interest with vectors followed by transformation into

    host cells by methods such as electroporation to enable such host cells to exhibit

    desired phenotypes. Plasmids and viruses are examples of the vectors used.

    2. Introduction of DNA fragments or genes of interest into host cells via

    micro-injection, macro-injection or micro-encapsulation.

    3. Cell or protoplast fusion and hybridization techniques between different

    cell types with different genetic materials, which produce heterologous genes in

    microorganisms/agents in a manner which cannot occur in nature.

    Genetically Modified Microorganism (GMM): A microorganism/agent whose

    genes or genetic material have been modified from its original counterpart in

    a manner that cannot occur in nature through genetic modification techniques for

    expression of desired phenotypes such as enzyme production. They include progeny

    of such microorganisms, which have inherited the modified genetic material.

    Genetically Modified Organism (GMO): An organism whose genetic material

    has been altered using modern biotechnology.

    Good Industrial Large Scale Practice (GILSP): Application of good

    microbiological practice in the use of harmless microorganisms/agents in industry.

    Such microorganisms/agents include non-pathogenic microorganisms/agents and

    GMMs that have a long history of safe use in industry or limited survival in the natural

    environment. Viruses, phages or plasmids that may cause disease are not used.

    HEPA filter: A high efficiency particulate air filter which can prevent the

    passage of small particles under 0.3 micrometers (µm) in size at 99.97% efficiency.

    Microorganisms cannot pass through this type of filter.

    Host or recipient cells: A cell that has incorporated modified DNA fragments

    or genes for expression of desired phenotypes.

    Inserted DNA: Heterologous DNA or gene that is introduced into a host cell

    by a vector or other genetic modification techniques to create desired phenotypes.

  • Biosafety Guidelines for Contained Use of Genetically Modified Microorganisms at Pilot and Industrial Scales ix

    Institutional Biosafety Committee (IBC): A committee commissioned by

    an institution or organization to provide advice and monitor work or projects related

    to modern biotechnology or genetic engineering according to biosafety guidelines.

    LD50: The amount of a chemical or biochemical substance that causes death

    among 50% of test animals.

    Microbial inactivation: The inactivation of GMMs from materials, equipment,

    tools, bioreactors and surfaces which may be contaminated with GMMs by using an

    appropriate procedure, such as heating or chemical treatment, in a manner that is

    not harmful to humans or the environment.

    Microorganism: A small living cell or particle that is able to reproduce and

    transfer genetic material. It includes bacteria, yeasts, molds, viruses, viroids, cultivated

    plant cells and cultivated animal cells.

    Operator: A person involved in GMM work within an organization/institution.

    Organization and institution: An organization where GMMs are used for

    commercial purposes at pilot and industrial scales, such as state enterprises,

    independent research institutes, factories and private companies.

    Owner or authorized representative: A person who is the head or designated

    representative of an organization and institute.

    Primary containment equipment: Equipment that is designed to provide

    containment or eliminate exposure to biohazardous materials, such as a biosafety

    cabinet or an isolater.

    Recombinant DNA molecule:

    1. Molecules constructed outside living cells by joining natural or synthetic

    DNA fragments to DNA molecules that can replicate in a living cell, or

    2. Molecules that result from the replication of those described above.

  • x Biosafety Guidelines for Contained Use of Genetically Modified Microorganisms at Pilot and Industrial Scales

    Risk assessment: An analytical process used for assessing risks posed to

    the environment or human health by GMM-related activities. Risks include direct

    and indirect risks, and those with immediate, delayed or downstream effects.

    Technical Biosafety Committee (TBC): A committee whose main responsibilities

    are :

    1. To provide technical consultation to any work or project related to modern

    biotechnology or genetic engineering according to biosafety guidelines;

    2. To identify risk categories for activities that are not clearly classified;

    3. To coordinate with agencies responsible for monitoring GMOs; and

    4. To enhance the efficiency of IBCs at the national level.

    The use of Genetically Modified Microorganisms (GMMs) in pilot plants

    and the industry: Includes the production of GMMs at a substantial scale (more than

    10 liters) to produce biological substances in contained conditions with no intention

    to release GMMs into the environment.

    Vector: DNA capable of self-replication in a living organism, used for

    introducing DNA or genes of interest into a host cell by ligation to such DNA. Examples

    include plasmids and viruses.

    Viroid: An infectious agent affecting living cells, smaller than a virus and

    consisting only of nucleic acid without a protein coat.

    Virus: A very small agent that cannot reproduce by itself but must replicate

    inside a living cell. One of its prominent characteristics is that it consists of either

    DNA or RNA but not both. Most antibacterials and antifungals have no effect on

    viruses even when used at concentrations that normally inhibit the growth of bacteria

    or fungi.
