| 1 The difference between this medium and "normal" SP4 medium (Medium 1076) is that the yeast extract was left out and DNA was added instead. Since most mycoplasmas use either glucose or arginine as their energy source one is added to the media. Do not combine both in one medium, arginine can inhibit the growth of some glucose utilizers (unknown reason). | |||||
