Description
Summary:A compatible microbial consortium with a high organic pollutant degradation ability, which includes a gram-positive <i>Brevibacillus parabrevis</i> B50 NCAIM B 001413 bacterial strain and a gram-negative <i>Pseudoxanthomonas mexicana</i> P32 NCAIM (P) B 001414 bacterial strain, was selected using high-throughput screening techniques. The compatible microbial consortium, encapsulated in alginate beds, was used to inoculate moving bed biofilm reactors from a small municipal wastewater treatment plant. The bioaugmentation performance of the inoculated consortium was evaluated by determining the water quality parameters before inoculation and one month after bioaugmentation treatment. The removal of organic matter was enhanced after treatment with the selected microbial consortium.
