PreparationofAgarplates
Prepare media and add 1.5 agar before autoclaving it (15g per liter). After autoclavation, cool the media in a 55 degree waterbath. Do not allow the solution to cool below this temperature as the agar gets solid at that temperature. At this step, one can leave the agar/media mixture for a long time. Before plating, add proper antibiotics and glucose if needed. Pour ca 25 ml per small agar plate (9 cm d......阅读全文
