Biodegradation of indeno (1, 2, 3- c, d) pyrene and dibenzo (a, h) perylene; high molecular weight PAHs by isolates of aerobic heterotrophic bacteria, cyanobacteria and its consortium from Boodo Creek characterized with brackish water was monitored for 56 days using GC- MS. The initial concentration of indeno (1, 2, 3- c, d) pyrene in treatment with aerobic heterotrophic bacteria (AHB) was 0.09 mg/l, cyanobacteria (CB) was 0.08 mg/l; AHB+CB was 0.3 mg/l and the control, C was 0.12. Dibenzo (a, h) perylene had AHB 0.10 mg/l; CB 0.07 mg/l; AHB + CB 0.21 mg/l and C 0.23 mg/l. The quantity of the PAH’s monitored reduced to 0 on day 56 in all the treatment options though fluctuation in the quantity of the HMW PAH’s was observed throughout the period monitored for biodegradation. Biodegradation of indeno (1, 2, 3- c, d) pyrene and dibenzo (a, h) perylene did not vary with time (p > 0.05).
