Among all the phenotypes, the relative abundance of the anaerobic phenotype showed a significant positive relationship with salinity, and the relative abundance of the stress-tolerant phenotype showed a marginally significant ( P < 0.1) positive relationship with salinity, while the relative abundance of facultative anaerobic and biofilm-forming phenotypes displayed a significantly negative relationship with salinity ( Fig. 4 ).
