The removal efficiencies for Chemical Oxygen Demand (COD), Total Nitrogen (T-N), Total Phosphorus (T-P), Suspended Solids (SS), and color intensity (96.4%, 78.4, 83.1, 84.4, and 92.0, respectively) 300\u2013531 days after the augmentation were generally improved after bioaugmentation. The denitrification linked to T-N removal appeared to contribute to the concomitant COD removal that triggered a reduction of sludge (up to 22%) in the same period of augmentation. Azo dye and aromatic compound degradation and other downstream pathways were highly metabolically interrelated. Augmentation of CES-1 increased microbial diversity in the later stages of augmentation when a strong microbial community selection of Acinetobacterparvus, Acinetobacterjohnsonii, Marinobacter manganoxydans, Verminephrobacter sp., and Arcobacter sp. occurred. Herein, there might be a possibility that the CES-1 augmentation could facilitate the indigenous microbial community successions so that the selected communities made the augmentation successful. The metagenomic analysis turned out to be a reasonable and powerful tool to provide with new insights and useful biomarkers for the complex environmental conditions, such as the full scale dye wastewater treatment system undergoing bioaugmentation.<\/jats:p>","DOI":"10.3390\/microorganisms9071503","type":"journal-article","created":{"date-parts":[[2021,7,14]],"date-time":"2021-07-14T10:13:42Z","timestamp":1626257622000},"page":"1503","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Metagenomic Insight of a Full Scale Eco-Friendly Treatment System of Textile Dye Wastewater Using Bioaugmentation of the Composite Culture CES-1"],"prefix":"10.3390","volume":"9","author":[{"given":"Aalfin Emmanuel","family":"Santhanarajan","sequence":"first","affiliation":[{"name":"Division of Civil, Environmental Engineering and Logistics System, Korea Maritime and Ocean University, Busan 49112, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7016-1454","authenticated-orcid":false,"given":"Woo-Jun","family":"Sul","sequence":"additional","affiliation":[{"name":"Department of Systems Biotechnology, Chung-Ang University, Anseong 06974, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0191-3499","authenticated-orcid":false,"given":"Keun-Je","family":"Yoo","sequence":"additional","affiliation":[{"name":"Division of Civil, Environmental Engineering and Logistics System, Korea Maritime and Ocean University, Busan 49112, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9697-2677","authenticated-orcid":false,"given":"Hoon-Je","family":"Seong","sequence":"additional","affiliation":[{"name":"Department of Systems Biotechnology, Chung-Ang University, Anseong 06974, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hong-Gi","family":"Kim","sequence":"additional","affiliation":[{"name":"Bayo Inc., Jinju 52665, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sung-Cheol","family":"Koh","sequence":"additional","affiliation":[{"name":"Division of Civil, Environmental Engineering and Logistics System, Korea Maritime and Ocean University, Busan 49112, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,14]]},"reference":[{"key":"ref_1","unstructured":"\u0160ajn, N.
