Dimensions and volumes of Cry3A crystals produced by different strainsa

  • a Means for each crystal dimension were calculated separately, whereas the volumes for those of DSM 2803 (n = 17), NB176 (n = 20), and 4Q7/pPFT3A (n = 19), were calculated for individual crystals by assuming that the length and width of each crystal were equal. Therefore, multiplying the mean dimensions for these three strains will yield values slightly different from those presented in the Volume column. The length and width of crystals produced by 4Q7/pPFT3As, however, were not equal, and thus the volume value is the product of the mean dimensions.

  • b Values followed by different letters were significantly different at P = 0.05.
