Table 2 Characteristics of biofilms. The BP-biofilms were developed within the brine pool for 72 h and the SV-biofilms were developed at the seep vent for 100 h. Biofilms were visualized by confocal laser scanning electron microscopy and z-stack images were analyzed by the software PHYLIP. Values are mean ± SD of 3 images. Polystyrene plates from the seep vent were lost during sample processing and thus no value was recorded
