Quinoline is biodegradable under anaerobic conditions, but information about the degradation kinetics and the involved microorganisms is scarce. Here, the dynamics of a quinoline-degrading bacterial consortium were studied in anoxic batch cultures containing nitrate. The cultures removed 83.5% of the quinoline during the first 80 hours, which were dominated by denitrification, and then switched to methanogenesis when the nitrogen oxyanions were depleted. Time-resolved community analysis using pyrosequencing revealed that denitrifiying bacteria belonging to the genus Thauera were enriched during the denitrification stage from 12.2% to 38.8% and 50.1% relative abundance in DNA and cDNA libraries, respectively. This suggests that they are key organisms responsible for the initial attack on quinoline. Altogether, 13 different co-abundance groups (CAGs) containing 76 different phylotypes were involved, directly or indirectly, in quinoline degradation. The dynamics of these CAGs show that specific phylotypes were associated with different phases of the degradation. Members of Rhodococcus and Desulfobacterium, as well as Rhodocyclaceae- and Syntrophobacteraceae-related phylotypes, utilized initial metabolites of the quinoline, while the resulting smaller molecules were used by secondary fermenters belonging to Anaerolineae. The concerted action by the different members of this consortium resulted in an almost complete anaerobic mineralization of the quinoline.

“…Dozens literatures have reported that isolated bacteria may lack of the capability of complete mineralization of hydrocarbon, especially for the recalcitrant compounds (33). Moreover, regardless of present or absent of oxygen, the first metabolite of quinoline was 2-hydroxyquinoline (10). This compound was thus preferentially considered as substrate of most predominant Thauera bacteria in the denitrifying bioreactor.…”

“…Various microorganisms capable of metabolizing quinoline aerobically have been isolated, mostly belonging to Pseudomonas (5–7), Rhodococcus (8) and Bacillus (9). The pathways of aerobic quinoline degradation have also been well described (10). However, little attention was paid to the anaerobic quinoline biodegradation.…”

18The complex bacterial community is predominated by several taxa, such as 19 Thauera and Rhodococcus, in a quinoline-degrading denitrifying bioreactor. Yet it 20 remains unclear about how the interactions between the different bacteria mediate the 21 quinoline metabolism in denitrifying condition. In this study, we designed a 22 sequence-specific amplification to guide the isolation of the most predominant 23 bacteria and obtained four strains of Thauera aminoaromatica, the representative of 24 one key member in the bioreactor. Test on these isolates demonstrated that all of them 25 were unable to strive on quinoline but could efficiently degrade 2-hydroxyquinoline, 26 the hypothesized primary intermediate of quinoline catabolism, under nitrate-reducing 27 condition. However, another isolate, Rhodococcus pyridinivorans YF3, corresponding 28 to the second abundant taxon in the same bioreactor, was found to degrade quinoline 29 via 2-hydroxyquinoline. The end products and removal rate of quinoline by isolate 30 YF3 were largely varied with the quantity of available oxygen. Specifically, quinoline 31 could only be converted into 2-hydroxyquinoline without further transformation under 32the condition with insufficient oxygen, e.g. less than 0.5% initial oxygen in the vials. 33However, if were aerobically pre-cultured in the medium with quinoline the resting 34 cells of YF3 could anaerobically convert quinoline into 2-hydroxyquinoline. A 35 two-strain consortium constructed with isolates from Thauera (R2) and Rhodococcus 36 (YF3) demonstrated an efficient denitrifying degradation of quinoline. Thus, we 37 experimentally proved that the metabolism interaction based on the 38 2-hydroxyquinoline cross-feeding between two predominant bacteria constituted the 39 mainstream of quinoline degradation. This work sheds light on the understanding of 40 mechanism of quinoline removal in the denitrifying bioreactor. 41 42 Keywords：Quinoline-degrading bioreactor, 2-hydroxyquinoline, microbial 43 interaction, cross-feeding, oxygen, denitrification 44 45 Importance 46 We experimentally verified the most predominant Thauera sp. was indeed active 47 degrader for the intermediate metabolites and the second abundant taxon 48 Rhodococcus exerted, however, key function for opening the food box for a complex 49 quinoline-degrading community. An ecological guild composed of two isolates was 50 assembled, revealing the different roles of keystone organisms in the microbial 51community. This study, to our best knowledge, is the first report on the cross feeding 52 between the initial attacker with unprofitable catalysis of reluctant heterocyclic 53 compounds and the second bacterium which then completely degrade the compound 54 transformed by the first bacterium. These results could be a significant step forward 55 towards elucidation of microbial mechanism for quinoline denitrifying degradation. 56 57 Introduction 58Quinoline and its derivatives are typical N-heterocyclic compounds that occur 59 widely in coal tar, shale oil and creosote,...

“…Previous studies have shown that bacteria require long-term domestication to degrade organic matter. This is particularly true when degrading refractory organic matter [5,32]. The same applies to degrading quinoline; without domestication, microbial metabolism efficiency is low and unstable for specific pollutants.…”

In order to strengthen the removal efficiency of heterocyclic nitrogenous compounds in industrial wastewater, a new bacterial strain identified as Bacillus sp. LH-1 was isolated, which could use quinoline as its sole carbon, nitrogen and energy source. The inducing conditions and kinetic properties of quinoline biodegradation by the strain were explored. The results showed that the strain Bacillus sp. LH-1 exhibited maximum tolerance of 700 mgL-1 quinoline concentration. After the strain was activated under the conditions of 200 mgL-1 quinoline for 120 h, the quinoline degradation was triggered, and the quinoline degradation rate increased approximately 10 times, from 2.030mg (L•h)-1 to 21.508 mg (L•h)-1. When the initial concentration of quinoline was 300 mgL-1 , more than 97% quinoline degradation occured within 12 h at pH 7 and at a temperature of 37ºC. The degradation kinetics of quinoline by strain Bacillus sp. LH-1 followed Haldane's model and indicated that the strain isolated in this study could be used for degradation of heterocyclic nitrogenous compounds in industrial wastewater.
