E. cottonii is one of a major contributor to the fisheries production. One of the inhibiting production factor is due to ice-ice disease.

The purposes of this research were to discover the clinical signs of seaweed (E. cottonii) that infected by bacterial consortium and the effect of the concentration levels of disease-causing bacteria ice-ice on seaweed (E. cottonii). The method in this study using a completely randomized design (CRD) with 4 treatments and 3 replications. Treatments were exposure of bacterial consortium K7, K8 and K9 at different concentrations namely A (10 6 CFU / ml), B (10 7 CFU / ml), C (10 8 CFU / ml), and D (without inoculation / control) to E. cottonii at 1-1,5 gram and 5 cm long was preserved in a glass jar filled with 200 ml of sterile sea water for 9 days. Bioecological condition was kept at 28 ° C, salinity 30 ‰, and pH 7 by using shaker at 100 rpm. The results showed that concentrations of a consortium of K7, K8 and K9 significantly different (P <0.05) to the absolute growth of E. cottonii. Clinical signs were ebserved by the appearance of white spots at the edge of thallus and spread up to along the thallus and end up with the broken thallus. Consortium of bacteria that cause the clinical signs were Corynebacterium sp., Baccilus sp., And Alteromonas sp..
