| Abstract |
Indole is a typical nitrogen-containing aromatic pollutant in coking wastewater, and it can be used for the microbial production of indigo, one of the oldest dyestuffs. In this study, the activated sludge system bioaugmented with two indigo-producing bacterial strains, wild strain Comamonas sp. MQ and recombinant Escherichia coli (ND_IND), was constructed to investigate indigo bioproduction from indole. During the operation, the bioaugmentation could promote the production of indigo, especially in early stages, and the indigo yields gradually increased from 17.5 ± 0.4 to 44.3 ± 0.5 mg/L with the increase of influent indole (80 to 282 mg/L). Illumina MiSeq sequencing revealed that the microbial community could have a noticeable shift driven by the bioaugmentation and high indole pressure. The indigenous bacteria could be more responsible for indigo production, and the dominant genera Comamonas, Diaphorobacter, Paracoccus, Aquamicrobium, Pseudomonas, and Truepera could be the key functional taxa. Based on FAPROTAX (Functional Annotation of Prokaryotic Taxa) analysis, the nitrogen metabolism-related functional groups could play important roles in indole biotransformation and indigo biosynthesis. This study should provide insights into microbial production of indigo by microbial communities. |

Attention Score in Context
This research output has an Altmetric Attention Score of 8. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 30 September 2018.
All research outputs
#4,140,101
of 23,103,903 outputs
Outputs from Applied Biochemistry and Biotechnology
#170
of 2,533 outputs
Outputs of similar age
#82,138
of 340,828 outputs
Outputs of similar age from Applied Biochemistry and Biotechnology
#2
of 18 outputs
Altmetric has tracked 23,103,903 research outputs across all sources so far. Compared to these this one has done well and is in the 81st percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 2,533 research outputs from this source. They receive a mean Attention Score of 3.2. This one has done particularly well, scoring higher than 93% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 340,828 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 75% of its contemporaries.
We're also able to compare this research output to 18 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 88% of its contemporaries.
