This implicates that a syntrophic consortium of microorganisms is always needed, whereas the exact composition of this consortium can not only change over time, but also vary between different reactors (Solli et al. 2014).
Reflecting the composition of the Airbus consortium, EADS is the product of a merger between Aerospatiale Matra of France, the DASA unit of DaimlerChrysler and Construcciones Aeronauticas of Spain.
The optimal composition of the mixed consortium (UV68, UVT1, DH5α) achieving the highest specific decolorization rate was (13%58%29%9%) and (0%:74%:26%) for decolorization of RR22 and RB5, respectively, with initial total cell density fixed at OD600 = 3.5 ± 0.28.
Future research should focus on the selection and engineering of robust microbial species, mathematical modelling of the composition and functionality of the consortium, and novel photobioreactor configurations.
16S rRNA gene amplicon high-throughput sequencing was performed to investigate the bacterial composition of microbial consortium DL38, and it was found that the most abundant organisms belonged to Enterobacteriaceae (95.57%), followed by Enterococcaceae (2.10%), Moraxellaceae (1.21%), and Streptococcaceae (0.64%).
The composition of this microbial consortium depends on various factors, such as substrate ingredients, temperature, pH, mixing, or the geometry of the anaerobic digester.
Introduction of a H2-producing new member into such consortia is therefore somewhat more challenging than altering the composition of a microbial consortium under mesophilic conditions.
The microbial composition of consortium CY-1 showed no significant difference when cultured under 10 and 20% salinity, indicating that the community structure of consortium CY-1 wastablele in hypersaline environments.
The absence of cellobiohydrolases (CBHs) and endoglucanases (specifically of families GH5 and GH9) in the RWS metasecretome could be related to the consortium response to the composition of the substrate or to their low abundance.
The intra- and interpersonal variation in the composition of the human microbiome significantly complicates the analysis of microbiome data (Consortium HMP 2012; Taglialatela et al. 2009).
