A novel thermally stable heteropolysaccharide based bioflocculant from hydrocarbonoclastic strain Kocuria rosea BU22S and its application in dye removal. The appearance of the biofilm was like the control not inoculated with sediment from HSCE, but the density and number of microbial clusters were much higher. He came to Japan in 1965 for training in farming and … The aim of this work was therefore to demonstrate, for the first time, proof of the feasibility of designating an efficient microbial halothermotolerant bioanodes from both hypersaline sediment (HSCE) and saline TDWW microbium able to treat textile wastewater and generating an electrical current collected via an electrode. On the contrary, bioanode formation was studied here in three-electrode electrochemical bioreactor installations to ensure well-controlled electroanalysis conditions, as explained in the review by Rimboud et al. Results from CV tests for the four different bioanodes are shown in Figure 2. Therefore, we concluded that these results provide for the first time a new noteworthy alternative for achieving treatment and recover energy, in the form of a high electric current, from real saline TDWW. CV was used to (i) validate the formation of an electroactive biofilm by comparing a control CV of the WE immersed in the TDWW with HSCE before starting the CA and a turnover CV at the end of the experiments and (ii) get access to I = f(E) of the bioanode that was shaped. Halotolerant bioanodes: The applied potential modulates the electrochemical characteristics, the biofilm structure and the ratio of the two dominant genera. The authors gratefully thank the European commission, the French ANR (ANR-15-NMED-0010), and the Ministry of High Education and Scientific Research of the Tunisian Republic (grant number LR11ES31) for their financial support within the framework of the WE-MET project (ERANETMED 2015 European call 14-035). Once the potential for electrical current generation and TDWW treatment of the halothermotolerant bioanodes had been proven via electrochemical and analytical tools, contributions of autochthonous microorganisms from TDWW and allochthonous from HSCE were investigated through comparative metagenomic analyses of biofilms, HSCE, and TDWW. Previous works have shown that the performance of bioanode systems is basically inversely proportional to the complexity of the substrate as in the case of TDWW (Pant et al., 2010; Pandey et al., 2016; Heidrich et al., 2018). A microorganism is a living thing that is too small to be seen with the naked eye. It is thus not at all a question here of developing a microbial fuel cell (MFC), a microbial electrolysis cell (MEC), or any other BES, judged too fluctuating and random to focus attention on the precisely targeted phenomenon, i.e., the formation of a bioanode without limitation caused by a limiting step of a larger and more complete BES process. Allochthonous is an antonym of autochthonous. 9

Durvasula, and V. Subba Rao (Boca Raton, FL: CRC Publishers), 33–64. It generates large volumes of textile dyeing wastewater (TDWW) containing high concentrations of saline, alkaline, and recalcitrant pollutants that could fuel tenacious and resilient electrochemically active microorganisms in bioanodes of bioelectrochemical systems. These methods involve (i) physical methods (coagulation–flocculation, adsorption, and filtration techniques), (ii) oxidation methods categorized as advanced oxidation processes (cavitation, photocatalytic oxidation, Fenton chemistry) and chemical oxidation using oxidizing agents (O3 and H2O2), and (iii) bioremediation methods (fungi, algae, bacteria) (Gosavi and Sharma, 2014; Yeap et al., 2014; Chandrakant et al., 2016; Chouchane et al., 2018; Jiang et al., 2018).

Utilization and transformation of aquatic humic substances by autochthonous microorganisms. For several reasons, such as eco-friendly, cost competitive, less sludge production, and giving non-hazardous metabolites or full mineralization (Hayat et al., 2015), the biological methods are qualified as the most sustainable method for wastewater treatment.

Then, bioanode coupons were washed carefully with sterile physiological water after incubation and dried at ambient temperature overnight. The few isolated clusters of bacterial colonies are probably mostly similar to suspended biological substances, kinds of microbial flocs participating in the non-bioelectrochemical oxidation of the COD of textile effluents.

ADVERTISEMENTS: Microorganisms which live in soil are algae, bacteria, actinomycetes, bacteriophages, protozoa, nematodes and fungi (Fig. (2019b). Evaluation of microbial proliferation on the outer surface of carbon felt electrodes by epifluorescence microscopy imaging. The poor accessibility to the porosity of the carbon felt is usually due to the clogging phenomena of the external pores of the electrode exerted by particles in suspension present in the wastewater (Blanchet et al., 2016). HC, BE, RA, SS, MN, and AC: performed microbial and genomic analyses. Two main reasons could explain in part this significant difference in average current densities: (i) industrial wastewater is generally more conductive (7 mS/cm) than domestic wastewater (1.5 mS/cm) (Yen et al., 2016) and (ii) the total organic matter concentration in industrial wastewater is between 5,000 and 12,000 mg/L (Rajeshwari et al., 2000), whereas that in domestic wastewater is between 320 and 740 mg/L (Almeida et al., 1999). Then, Illumina Miseq 16S rRNA sequencing was performed in order to analyze the composition of the microbial communities in HSCE and TDWW samples and in different biofilms. 239, 82–86. Bioeng. While we typically think of microorganisms as being unicellular, there are also many multicellular organisms that are too small to be seen without a microscope. All experiments were conducted in a 500 ml glass three-electrode reactor containing 80% of real textile effluents and 20% of saline sediments. doi: 10.1016/j.biortech.2015.02.097, Blanchet, E., Erable, B., De Solan, M. L., and Bergel, A. In this study, a designed hybrid bacterial halothermotolerant bioanode incorporating indigenous and exogenous bacteria from both hypersaline sediment of Chott El Djerid (HSCE) and TDWW is proposed for simultaneous treatment of real TDWW and anodic current generation under high salinity. A core bacterial community composed of three autochthonous strains, Achromobacter sp., C. acidovorans, D. gadei, and four allochthonous strains, P. aquaticus, G. sulfurreducens, G. metallireducens, and M. sediminum, ensures the effectiveness of the bioanode by producing high current density (12.5 A/m2) and a total of 91% of COD removal efficiency. HC, RA, BE, and AC: manuscript preparation and revision. This type of electroactive biofilm enveloping the carbon fibers is generally a feature of biofilms in hypersaline environments (Rousseau et al., 2014). Front. Bioresour. The WE made of a porous carbon felt of 6 cm2 projected surface area was electrically connected to a platinum wire (1 mm diameter and 15 cm long) and polarized at −0.1 V/SCE. Samples were a mixture of saturated water and sediment (2:1 vol.:vol.) Beyond these potential values, i.e., for potentials more positive than −0.1 V or 0.0 V/SCE, the maximum speed of the exchange current is reached, and a current plateau is therefore observable between −0.1 V and +0.3 V/SCE.

Biofilms were then imaged with epifluorescence microscopy as described by Blanchet et al. These strains were also noticed in previous studies on microbial communities in textile wastewater (Meerbergen et al., 2016). All experiments were performed in triplicates under the same conditions to prove the reproducibility of experimental results. Microorganisms differ from each other not only in size, but also in structure, habitat, metabolism, and many other characteristics. A 1 cm thick cross-section of the electrodes was prepared, and observations were then performed in the center of the porosity of the electrodes after staining the dead and living microbial cells with acridine orange.

However, in hypersaline sediment sample of Chott el Djerid (HSCE), source of the allochthonous community, the most abundant phylum was Proteobacteria (86%) approximately seven times higher than that in rTDWW (12.5%). Tenacious, resistant, and exoelectrogenic microorganisms used in bioelectrochemical systems (BES) can perform the dual function of degrading pollutants and recovering in the form of electrical energy, the energy resulting from the oxidation of these pollutants. Energy 168, 706–723. Indeed, previous studies reported that exoelectrogenic populations have favorably demonstrated an added value for the treatment of recalcitrant pollutants, such as azo dyes, petroleum hydrocarbon, and heavy metals (Adelaja et al., 2015; Choudhury et al., 2017; Monzon et al., 2017; Grattieri and Minteer, 2018; Vijay et al., 2018; Askri et al., 2019; Elabed et al., 2019a,b). Finally, TDWWS3 showed an intermediate colonization profile between TDWWS1 and TDWWS2, with a thin continuous biofilm that closely covered the surface fibers of the carbon felt. Figure 5B indicates that the relative abundances of bacteria at phylum level in TDWWS1, TDWWS2, and TDWWS3 biofilms are quite similar, whereas those in TDWW biofilm show some differences. Hazard. Articles, Guangdong University of Technology, China. Hypersaline sediments used as inoculums were sampled from an extreme environment Chott El Djerid, located in the south of Tunisia (N 33°59′965″ and E 08°25′332″). Evolution of the current density (A/m2) vs. time (days) for experiments on a carbon felt electrode of 6 cm2 projected surface area polarized at −0.1 V/SCE in a reactor containing textile dyeing wastewater (TDWW) and reactors containing 80% of TDWW and 20% of saline sediments (TDWWS1, TDWWS2, TDWWS3). For bioremediation of wastewater containing recalcitrant pollutants, these findings revealed that reactors inoculated with HSCE were found to be comparatively higher in COD removal efficiency than other textile wastewater treatments, such as (i) anaerobic internal circulation reactor (COD removal = 87%), (ii) Fenton's process with and without pH adjustment where COD removal was 89 and 33%, respectively (Hayat et al., 2015), and (iii) the combination of homogenization decantation and membrane treatments (COD removal = 66%) (Buscio et al., 2015). Remarkably, the maximal current performance reached during the experiments was almost the same for the three bioanodes TDWWS1, TDWWS2, and TDWWS3. doi: 10.1007/s00449-014-1246-x.

The start of current production was observed almost after 2 days of polarization for all three bioanodes co-inoculated with HSCE, in comparison with the TDWW bioanode, where current production was only recorded from day 5 with very low densities throughout the experiment. By comparing the bacterial community of these three biofilms to that hosted TDWW, considered as a control, we found that TDWW harbored less bacteria belonging to the Proteobacteria (9.47%) and Bacteroidetes (3.22%) phyla.

The lack of agitation of the reaction medium, the hydrophobicity of the carbon felt, and the low growth rate of microorganisms in the textile wastewater are certainly individual or combined tracks that can partly justify the low internal colonization rate of the 3D felt electrodes. doi: 10.1007/s00792-015-0805-7. Another CV cycles were performed when the maximum values of the current density were reached for all reactors (turnover CVs). (2018). The obtained results demonstrated that the TDWW, although rather recalcitrant to biological treatment, is found as the most suitable effluent to generate electric current using hypersaline sediment as a source of tenacious and exoelectrogen biocatalysts. Comparative decolorization of dyes in textile wastewater using biological and chemical treatment. This suggests that the electroactive community developed faster and more efficiently in reactors inoculated with HSCE. After 21 days of incubation, 57 microorganisms were isolated. One of the objectives was the optimisation of the living conditions of the autochthone microorganisms taking advantage of their capability to degrade pollutants. 283, 211–217. Hope it helped! Eng. It is worth noting that the bacterial phyla identified in the three biofilms show heterogeneous profiles composed of phyla found in rTDWW and in HSCE.
