--- Adds automated microbial identification system in Annex A.1 biochemical equipment and materials, vibrio chromogenic medium;

--- Reference SN/T 3064.1, Appendix A.3 processing samples of media content increases the processing of biological samples;

--- Based WS289, a rapid increase in the secondary test method in Appendix A.4;

--- Adjust the content section in Appendix A.5.2 of Appendix A.5.2.2 added vibrio chromogenic medium content, based on the main WS289 to increase the strain for the review Appendix A.6.5.3 biochemical test system;
