The Flotation Characteristics Of Bacillus Cells And Spores
The increase of hydrophobicity of bacillary cells positively correlated with their capacity to flotation. That is why the use of flotation for the age fractionation of bacillary cells is possible spores are concentrated in the foam while vegetative cells remain in the culture liquid.
