An aerobic consortium CN-1 has been constructed using five different bacteria namely Pseudomonas aeruginosa CLRI BL22, Moraxella osloensis, Citrobacter freundii (SUB3 & SUB6) and Pseudomonas aeruginosa isolated from textile effluent. The enhanced degradation of Acid Black 24 by this constructed aerobic consortium CN-1 compared to the constituent strains, which is evident from the kinetic studies, may be attributed to the concerted activities of the bacterial strains. The consortium CN-1 degraded 83% in 48h of incubation whereas the individual bacteria required more than 120 h of incubation to achieve the same level of degradation. The degradation was found to follow first order with the K1 value of 0.101332h-1 which is very high compared to the K1 values of AB24 decolorization mediated by individual constituent microorganisms.
