Improved biological treatment of medium-strength wastewater at low temperatures via diversity manipulation of psychrophilic bacterial consortiums
Author(s): Peter Ackroyd*
In order to create effective bioaugmentation formulations for improved wastewater treatment at low temperatures or under temperature-variable settings, psychophilic bacteria are excellent biocatalysts. Here, we investigated the impact of an artificial bacterial consortia's microbial diversity on the biomass gross yields (measured through OD600) and removal efficiency of soluble chemical oxygen demand (mg sCOD removed/mgs COD introduced) in synthetic, medium-strength wastewater using various biodiversity indices [based on Species Richness (SR), Phylogenetic Diversity (PD), and Functional Diversity (FD)]. We created artificial consortia from one to six 4 °Cisolated bacterial strains using combinatorial biodiversity experiments.In monocultures, tricultures, pentacultures, and hexacultures, respectively, increased species richness led to greater COD removal efficiency (i.e., 0.266..
