Advances in industrial microbiome based on microbial consortium for biorefinery

Abstract

One of the important targets of industrial biotechnology is using cheap biomass resources. The traditional strategy is microbial fermentations with single strain. However, cheap biomass normally contains so complex compositions and impurities that it is very difficult for single microorganism to utilize availably. In order to completely utilize the substrates and produce multiple products in one process, industrial microbiome based on microbial consortium draws more and more attention. In this review, we first briefly described some examples of existing industrial bioprocesses involving microbial consortia. Comparison of 1,3-propanediol production by mixed and pure cultures were then introduced, and interaction relationships between cells in microbial consortium were summarized. Finally, the outlook on how to design and apply microbial consortium in the future was also proposed.

Bacterial Synergism in Lignocellulose Biomass Degradation – Complementary Roles of Degraders As Influenced by Complexity of the Carbon Source

“…These studies thus show the key importance of metabolic complementarity in LCB degradation, in which the cooperation between synergistic pairs is driven by exchanges of key metabolites, or by niche partitioning. However, we still do not understand the plethora of mechanisms, as well as the dynamism, that play roles in the microbial attack on the LCB wheat straw ( Pandhal and Noirel, 2014 ; Dolinšek et al, 2016 ; Ghosh et al, 2016 ; Jia et al, 2016 ; Jiang et al, 2017 ). For instance, it remains unclear to what extent the composition/structure of the substrate affects the interactions between collaborating degraders.…”

The Impact of Saccharomyces cerevisiae on a Wine Yeast Consortium in Natural and Inoculated Fermentations

“…Synthetic microbial consortia composed of a subset of culturable strains that simulate the natural community and preserve the indigenous interactions shaped by co-adaptation/evolution, provide a tractable model system with reduced complexity ( De Roy et al, 2014 ; Ponomarova and Patil, 2015 ), which makes it easier to study interspecific interactions ( Jagmann and Philipp, 2014 ; Jiang et al, 2017 ). Such a model system also opens opportunities to employ methods inapplicable to complex systems, e.g., species quantitation can easily be done with selective plating, quantitative PCR, fluorescent in situ hybridization (FISH), and flow cytometry ( Xufre et al, 2006 ; Grube and Berg, 2009 ; Zott et al, 2010 ; Ponomarova and Patil, 2015 ).…”

Bioleaching of copper from waste printed circuit boards by bacteria-free cultural supernatant of iron–sulfur-oxidizing bacteria

“…High oxidation activity of strains was screened to bioleach the PCBs (Bas et al 2013;Nie et al 2015). Mixed culture whose performance was better than that of single bacteria was used (Jiang et al 2017;Liang et al 2013). The tolerance of bacteria could be improved by acclimatization of bacteria to the condition of PCBs (Arshadi and Mousavi 2014).…”
