The enzymatic index represents the mean halo diameter of degradation/ diameter of bacterial colony in cm of four replicate experiments. Mean values of enzymatic indices within the same column followed by the same letter don’t differ significantly among themselves (Turkey's b, p<0.05. Isolates grouped together based on morphology and biochemical tests. Key for identifying the codes: Site: G- Gazi bay and M-Mida creek Media: Act/Ac- M1 media, N- Nutrient agar mixed with NaCl, R-M1 media, A – Differential media, SN1- NASEA media, B-DNBA plus seawater and D- DNBA plus distilled water. Numeral; 1-27. Source plant; XG-Xylocarpus granatum, AM-Avicenia marina, SA- Sonneratia alba, BG- Bruguiera gymnorhiza, LR/ Lumn- Lumnitzera racemosa and RM-Rhizophora mucronata. Plant part; leaf and root.
