“…The high abundance of members of Proteobacteria in these locations could be attributed to their capability to perform a great variety of metabolic functions such as sulfate and nitrate co-reduction [30,31]. However, Proteobacteria decreased drastically in the effluent, which was also observed by Li et al [17].…”

Anaerobic digestion technology is being widely employed for sustainable management of organic wastes generated in animal farms, industries, etc. Nevertheless, biodigester microbiome is still considered a “black box” because it is regulated by different physico-chemical and operational factors. In this study, the bacterial diversity and composition in different sites of a full-scale lagoon type biodigester (23,000 m3) fed with dairy manure, viz., the influent, beginning, middle, final and effluent were analyzed. The biodigester registered a total of 1445 OTUs, which demonstrated the complex microbial ecosystem in it. Of them, only six OTUs were shared among all the different sampling points. The most abundant phyla belonged to Firmicutes, Proteobacteria, Latescibacteria and Thermotogae. The Simpson and Shannon index showed that the highest microbial diversity was observed in the beginning point of the biodigester, meanwhile, the lowest diversity was recorded in the middle. Based on the UniFrac distances, microbial communities with high similarity were recorded in the middle and final of the biodigester. It can be clearly observed that bacterial communities varied at the different points of the biodigester. However, based on metagenome predictions using PICRUSt, it was found that independent of the differences in taxonomy and location, bacterial communities maintained similar metabolic functions.

Aquaculture systems are becoming more intensive to increase economic efficiency (Ren et al., 2019). Large amounts of feed are put into the systems to enhance the growth of cultured animals, which leads to an elevated concentrations of organic waste from uneaten feed and faeces. Ammonia is produced when those organic waste is decomposed (Li & Boyd, 2016). The conversion methods for removing ammonia nitrogen in aquaculture systems are photoautotrophic removal by algae, autotrophic bacterial conversion of ammonia to nitrate and heterotrophic bacterial conversion of ammonia-nitrogen directly to microbial biomass (Dauda, 2020;El-Sayed, 2020). None of the three pathways exist alone, and the dominant one depends on the management of the aquaculture systems (Dauda, 2020).

“…It has been reported that changes in N/S ratio under heterotrophic conditions caused changes in products distribution similar to that observed here. Additionally, changes in N/S ratio led to changes in the heterotrophic microbial community structure [22]. There may similarly have been autotrophic community changes in the present study, but this was not investigated.…”
