TL;DR: In this paper, the authors argue that there is an urgent need for re-engineering of the anthropogenic nitrogen cycle in order to find a long-term sustainable solution, and they argue that the line of direct protein production as animal feed or even for human consumption by using microorganisms is a welcome opportunity to alleviate the very significant burden that the contemporary food production systems have on our planet.

TL;DR: Overall, this work shows that the combined fermentation, electrochemistry and homogeneous catalysis enables fine chemical production from side streams.

TL;DR: Ureolysis was identified as the only process significantly impacting the microbial community, indicating external inoculation would not be required to serve as a controlled environment to release NH3 and remove divalent cations to prevent scaling in downstream transport and processing.

TL;DR: Although salinity represents a major driver for microbial community structure, proper acclimation yielded highly efficient systems treating molasses, irrespective of the inoculum origin, indicating that biomass turnover rather than methanogenesis represents the main limitation to further increasing VFA production with molasses.

TL;DR: The microbial community data revealed the co-dominance of two major OTUs during co-production of i- butyrate and n-butyrate in two distinctive phases throughout a period of 54 days and 28 days, respectively, and the cross-comparison of product profile with microbial community composition suggests that the relative abundance of Clostridium sp.
