“…Chromate resistance and reduction. Recent studies have focused on the ability of Shewanella species to reduce chromate (19,(21)(22)(23)(24). For instance, S. oneidensis MR-1 can resist 1 mM chromate, whereas, Shewanella algidipiscicola H1 grows in 3 mM chromate (18,26).…”

“…It was shown that S. oneidensis MR-1 survives in elevated concentrations of chromate by developing several resistance strategies, such as oxidative stress protection, detoxification, SOS-controlled DNA repair mechanisms, and different pathways for Cr(VI) reduction (18,19). Indeed, in addition to enzymatic reduction of chromate [hexavalent chromium Cr(VI)] into a less mobile form [Cr(III)] that presents a decreased toxicity (20)(21)(22)(23), S. oneidensis, like other members of the genus, possesses a chromate efflux pump able to extrude chromate from the cell, increasing its resistance against the metal (24).…”

The genus Shewanella is well known for its genetic diversity, its outstanding respiratory capacity, and its high potential for bioremediation. Here, a novel strain isolated from sediments of the Indian Ocean was characterized. A 16S rRNA analysis indicated that it belongs to the species Shewanella decolorationis. It was named Shewanella decolorationis LDS1. This strain presented an unusual ability to grow efficiently at temperatures from 24°C to 40°C without apparent modifications of its metabolism, as shown by testing respiratory activities or carbon assimilation, and in a wide range of salt concentrations. Moreover, S. decolorationis LDS1 tolerates high chromate concentrations. Indeed, it was able to grow in the presence of 4 mM chromate at 28°C and 3 mM chromate at 40°C. Interestingly, whatever the temperature, when the culture reached the stationary phase, the strain reduced the chromate present in the growth medium. In addition, S. decolorationis LDS1 degrades different toxic dyes, including anthraquinone, triarylmethane, and azo dyes. Thus, compared to Shewanella oneidensis, this strain presented better capacity to cope with various abiotic stresses, particularly at high temperatures. The analysis of genome sequence preliminary data indicated that, in contrast to S. oneidensis and S. decolorationis S12, S. decolorationis LDS1 possesses the phosphorothioate modification machinery that has been described as participating in survival against various abiotic stresses by protecting DNA. We demonstrate that its heterologous production in S. oneidensis allows it to resist higher concentrations of chromate. IMPORTANCE Shewanella species have long been described as interesting microorganisms in regard to their ability to reduce many organic and inorganic compounds, including metals. However, members of the Shewanella genus are often depicted as cold-water microorganisms, although their optimal growth temperature usually ranges from 25 to 28°C under laboratory growth conditions. Shewanella decolorationis LDS1 is highly attractive, since its metabolism allows it to develop efficiently at temperatures from 24 to 40°C, conserving its ability to respire alternative substrates and to reduce toxic compounds such as chromate or toxic dyes. Our results clearly indicate that this novel strain has the potential to be a powerful tool for bioremediation and unveil one of the mechanisms involved in its chromate resistance.

“…Most of the biotechnological applications implicating Shewanella species concern bioremediation. Shewanella strains can be used for degradation of hydrocarbides (Gentile et al 2003;Martín-Gil, Ramos-Sánchez and Martín-Gil 2004;Deppe et al 2005;Gerdes et al 2005;Hassanshahian 2014;Suganthi et al 2018), dyes (Xu et al 2005;Chen et al 2008;Hong and Gu 2010;Cai et al 2012;Patel and Bhatt 2015;Ito et al 2016;Liu et al 2018, Lemaire et al 2019, antibiotics (Mao et al 2018;Wang et al 2019), pesticides (Chen and Rosen 2016), synthetic pollutants (Petrovskis, Vogel andAdriaens 1994, de Santana et al 2019) and toxic oxides, such as chromate or tellurite (Baaziz et al 2017;Soda et al 2017;Valdivia-González et al 2017;Wang et al 2017;Meng et al 2018, Lemaire et al 2019.

The Gram-negative Shewanella bacterial genus currently includes about 70 species of mostly aquatic γ-proteobacteria, which were isolated around the globe in a multitude of environments such as surface freshwater and the deepest marine trenches. Their survival in such a wide range of ecological niches is due to their impressive physiological and respiratory versatility. Some strains are among the organisms with the highest number of respiratory systems, depending on a complex and rich metabolic network. Implicated in the recycling of organic and inorganic matter, they are important components of organism-rich oxic/anoxic interfaces, but they also belong to the microflora of a broad group of eukaryotes from metazoans to green algae. Examples of long-term biological interactions like mutualism or pathogeny have been described, although molecular determinants of such symbioses are still poorly understood. Some of these bacteria are key organisms for various biotechnological applications, especially the bioremediation of hydrocarbons and metallic pollutants. The natural ability of these prokaryotes to thrive and detoxify deleterious compounds explains their use in wastewater treatment, their use in energy generation by microbial fuel cells and their importance for resilience of aquatic ecosystems.

“…Cr(VI) can be converted to Cr(III) in the presence of reductants, such as ferrous iron, manganous ion, organic phenols, and a reducing microorganism [ 12 , 13 ]. Cr(III) can be oxidized to Cr(VI) through interaction with manganese dioxide, and the conversion is substantially influenced by the equilibrium between the dissolved and solid phases of Cr(III); furthermore, the kinetics are slow [ 14 ].…”

A novel composite of montmorillonite-supported carboxymethyl cellulose-stabilized nanoscale iron sulfide (CMC@MMT-FeS), prepared using the co-precipitation method, was applied to remediate hexavalent chromium (Cr(VI))-contaminated soil. Cr(VI)-removal capacity increased with increasing FeS-particle loading. We tested the efficacy of CMC@MMT-FeS at three concentrations of FeS: 0.2, 0.5, and 1 mmol/g, hereafter referred to as 0.2 CMC@MMT-FeS, 0.5 CMC@MMT-FeS, and 1.0 CMC@MMT-FeS, respectively. The soil Cr(VI) concentration decreased by 90.7% (from an initial concentration of 424.6 mg/kg to 39.4 mg/kg) after 30 days, following addition of 5% (composite–soil mass proportion) 1.0 CMC@MMT-FeS. When 2% 0.5 CMC@MMT-FeS was added to Cr(VI)-contaminated soil, the Cr(VI) removal efficiency, as measured in the leaching solution using the toxicity characteristic leaching procedure, was 90.3%, meeting the environmental protection standard for hazardous waste (5 mg/kg). The European Community Bureau of Reference (BCR) test confirmed that the main Cr fractions in the soil samples changed from acid-exchangeable fractions to oxidable fractions and residual fractions after 30 days of soil remediation by the composite. Moreover, the main complex formed during remediation was Fe(III)–Cr(III), based on BCR and X-ray photoelectron spectroscopy analyses. Biotoxicity of the remediated soils, using Vicia faba and Eisenia foetida, was analyzed and evaluated. Our results indicate that CMC@MMT-FeS effectively immobilizes Cr(VI), with widespread potential application in Cr(VI)-contaminated soil remediation.
