细菌比动物细胞更少受到盐的渗透作用的影响，因细菌的细胞壁不大有渗透性。

Bacteria are less affected by the osmotic effect of salt than animal cells because bacterial cell walls are less permeable.

这种生物膜一接触到金，就会使之溶解，产生的有毒金离子又会破坏这种细菌的细胞壁。

The biofilm dissolves the gold on contact, creating toxic gold ions that can break down the bacteria's cell walls.
