“…The relative abundance of Marinobacterium and Mangrovibacterium in MDC‐E ranged from 1.36% to 19.48% and from 0.67% to 12.48%, respectively. Marinobacterium within Proteobacteria was reported to perform the denitrification in both anaerobic and aerobic conditions during the nitrogen removal process, 47 and as a genus involved in COD removal, was more enriched at a high influent NH 4 + concentration 48 . Therefore, it might be a key role in COD and NH 4 + removal in this paper.…”

Notably, a previous study has suggested that Rhodococcus within Actinobacteria was involved in nitrification under low-DO conditions and denitrification, 49,50 which demonstrates a potential use of the genus for wastewater treatment and contribution to the NH 4 + removal.…”

BACKGROUND: Due to the rapid development of shale gas extraction, the treatment of flowback water (FW) is becoming one major challenge because of its high saline, high ammonium (NH 4 +), high phosphorus (PO 4 3−), and complex organic contents. This study aimed to treat the high-salinity synthetic FW and recover nutrient using the air-cathode (PMo/CB) microbial desalination cells (MDCs). RESULTS: The removal efficiency of chemical oxygen demand (COD) exceeded 90% along with an electricity generation of 105.6 mW m −2. The highest removal and the recovery efficiency of 300 mg L −1 NH 4 + and 100 mg L −1 PO 4 3− were 65.6 ± 19.0% and 75.8 ± 32.0%, 52.6% and 57.8%, respectively. High-throughput sequencing analysis of anodic biofilms indicated that Firmicutes, Bacteroidetes, and Proteobacteria enriched at high influent NH 4 + concentration were responsible for producing electricity and degrading complex organics. Two denitrifying bacteria, Trichococcus and Marinobacterium, promoted the COD removal and also improved the electricity generation. Rhodococcus, a kind of heterotrophic nitrification-denitrification bacteria, contributed to nitrification in the cathodic chamber along with enhancing the denitrifying degradation of COD. Nitrincolaceae, capable of heterotrophic nitrate reduction to ammonium, were favorable to the recovery of NH 4 +. CONCLUSIONS: Overall results concluded that PMo/CB-MDC could be a promising alternative technique for the efficient treatment of FW and a pretreatment process for separating nutrient from the recovery chamber.

A Gram-negative, motile, rod-shaped bacteria, designated D7T, was isolated by using the dilution-to-extinction method, from a soil sample taken from Rambla Salada (Murcia, Spain). Growth of strain D7T was observed at 15–40 °C (optimum, 37 °C), pH 5–9 (optimum, 7) and 0–7.5% (w/v) NaCl (optimum, 3%). It is facultatively anaerobic. Phylogenetic analysis based on 16S rRNA gene sequence showed it belongs to the genus Marinobacterium. The in silico DDH and ANI against closest Marinobacterium relatives support its placement as a new species within this genus. The major fatty acids of strain D7T were C16:0, summed feature 3 (C16:1 ω7c/C16:1 ω6c) and summed feature 8 (C18:1 ω7c/C18:1 ω6c). The polar lipid profile consists of phosphatidylethanolamine, phosphatidylglycerol and two uncharacterized lipids. Ubiquinone 8 was the unique isoprenoid quinone detected. The DNA G + C content was 59.2 mol%. On the basis of the phylogenetic, phenotypic, chemotaxonomic and genomic characterization, strain D7T (= CECT 9818T = LMG 31312T) represents a novel species of the genus Marinobacterium for which the name Marinobacterium ramblicola sp. nov. is proposed. Genome-based metabolic reconstructions of strain D7T suggested a heterotrophic and chemolitotrophic lifestyle, as well as the capacity to biosynthetize and catabolize compatible solutes, and to degrade hydrocarbon aromatic compounds.

“…Therefore, the sequencing results were sufficient to reflect the true status of the microorganisms in the sample, meaning that the samples were representative. 34 The Shannon and Simpson indices were employed to assess the diversity of the microbial community, whereas the Chao index was utilized to assess the microbial richness. 35 In this study, the total number of sequences detected in the R 2 sample exposed to a MF intensity of 30 mT was as high as 57 801, whereas that of R 1 without magnetic field treatment was 38 615.…”
