Law of coloring of change orchid family name , can be bacterial cent two kinds big : use method of this kind of coloring , it is to use gentian to catch a bug first , all bacteria caught purple , besmear again next with iodic fluid , will strengthen the tie of dye and bacterium body , the alcohol of 95 comes to reoccupy decolour 20 30 seconds , some bacteria not by decolour , still withhold purple , some bacteria are become by decolour colorless , reoccupy answer is red finally answer catch 1 minute , the result already was caught by the bacterium of decolour cheng gong is lubricious , not the bacterium of decolour still keeps purple , no longer chromatic , such , every is caught purple bacterium calls bacterium of positive of change orchid family name ; ran chenggong calls bacterium of negative of change orchid family name lubriciously
