GUERRERO PORRAS, Liliana et al. Microbial consortium native catalytically active for removal of indigo and surfactants in textile industry wastewater through an immobilization matrix. Rev. colomb. biotecnol [online]. 2014, vol.16, n.1, pp.177-187. ISSN 0123-3475.  https://doi.org/10.15446/rev.colomb.biote.v16n1.33172.

The aim of this study was isolate six different bacterial strains from water discharges used in dyeing yarn with indigo, capable of degradation of organic compounds with indigo dye and three type nonionic surfactants. Similarly, various supporting media were evaluated for immobilizing the selected strains. Strains with better capacity were combined to form four consortia (I, II, III, and IV) in order to enhance the bleaching process, whereas synergy and complement metabolic activities of mixed cultures within a community increase microbial removal efficiency of organic load. Removal percentages were achieved which were 64, 73, 76 and 59%, respectively. Individual cultures showed no higher than rates reported by consortia removal, which suggests in its use for the removal of indigo dyes in wastewater.
