No provisions are made presently amino acids supplier for food industry big-scale research or production of viable organisms containing recombinant DNA molecules that require BL4 containment on the laboratory scale. Level of physical containment is required for big-scale analysis or manufacturing of viable organisms containing recombinant DNA molecules that require BL3 containment at the laboratory scale. Appendix K replaces parts of Appendix G when quantities in excess of 10 liters of tradition are involved in research or manufacturing. For large-scale research or production, 4 bodily containment ranges are established: GLSP, BL1-LS,BL2-LSand BL3-LS.
