abstract：:Two subpopulations of Bacillus megaterium spores (1.360 and 1.355 g/ml) were obtained by density gradient centrifugation. The heavier spores had a higher thermoresistance (e.g., D(80) = 186 versus 81 min) and a higher DNA content (1.25 x 10 versus 0.65 x 10 g per spore, apparently corresponding to digenomic versus mon...
