| Abstract: | The index of hydrophobicity and the hydrophilic-hydrophobic properties of seven microbial cultures were determined by studying their adhesion to n-hexadecane. The index of hydrophobicity was shown to be a stable characteristic of a culture grown in media with different carbon sources. As was found for Escherichia coli K-12 and Acinetobacter calcoaceticus K-9 whose hydrophobicity indicates were quite different, the character of cell hydration was virtually independent of the growth phase and did not change upon either submerged or superficial cultivation. |
