  1. aBacterial identification at the genus level with the name of the isolates in parentheses. The isolates were named according to host and the location of the samples: MCR, Mangrove Cananéia Rhizophora mangle; MCA, Mangrove Cananéia Avicennia nitida; MBR, Mangrove Bertioga Rhizophora mangle; MBA, Mangrove Bertioga Avicennia nitida.
  2. bThe enzymatic index was measured by determining the ratio of degradation halo diameter/bacterial colony diameter. Values with the same letter within a column are not significantly (p < 0.05) different according to the Scott-Knott test. The results represent the means of four replicates for each isolate.
