“…S. oneidensis MR-1 has been shown to be inhibited by these metals. , While there was no difference in the visual confirmation of growth based on media turbidity, specific growth rates were not measured. The reduced extraction rates in Wishbone Hill could have been from inhibited growth due to heavy metals or other nonmeasured toxic materials.…”

Alaskan coal mines with high rare earth element (REE) levels (286–524 mg/kg) serve as an alternative domestic REE source. Existing leaching/separation technologies require hazardous chemicals to recover REEs from the feedstock with multiple downstream purification stages, increasing the overall operational cost. This study aims at bioweathering coal from two Alaskan coal mines (Wishbone Hill and Healy) at three specific gravity fractions (1.3 float and 1.3 and 1.5 sink) using Shewanella oneidensis MR-1 for achieving REE recovery. Optimizing the bioweathering process by varying the solids percentages (5.7 to 14.3% w/v), particle size (74 to 1180 μm), incubation temperatures (30 to 34 °C), and inoculum dosing (0.2 to 1% v/v) resulted in the highest recovery of neodymium (75.3%) and total REEs (98.4%) from 1.3 float Wishbone Hill and 1.3 sink Healy coal, respectively. Chemical leaching had higher recovery of REEs in most fractions; however, bioweathering had enhanced recovery of the individual REEs, especially scandium, yttrium, ytterbium, terbium, erbium, and lutetium from Healy coal at low specific gravity samples and yttrium from Wishbone Hill coal at high specific gravity samples. The results highlight the potential for developing cost-effective and selective REE biorecovery processes that can help address the global critical mineral supply chain risk.

“…Shewanella and Pseudoalteromonas have been reported to be prevalent components of the ascidian gut microbiome (Schreiber et al 2016 ; Ueki et al 2019 ). Shewanella putrefaciens and Shewanella oneidensis show significant resistance to arsenic, lead, and cadmium (Huang et al 2011 ; Jaafar et al 2016 ), whereas Pseudoalteromonas citrea and Pseudoalteromonas nigrifaciens show tolerance to copper, cadmium, mercury, and nickel (Ivanova et al 2001 ). Staphylococcus shows resistance to arsenic, mercury, silver, and cadmium (Lauková 1994 ; Lawal et al 2021 ) while Ferrimonas kyonanensis , Photobacterium damselae , and Halobacillus sp.…”

The sea squirt Ciona robusta (formerly Ciona intestinalis type A) has been the subject of many interdisciplinary studies. Known as a vanadium-rich ascidian, C. robusta is an ideal model for exploring microbes associated with the ascidian and the roles of these microbes in vanadium accumulation and reduction. In this study, we discovered two bacterial strains that accumulate large amounts of vanadium, CD2-88 and CD2-102, which belong to the genera Pseudoalteromonas and Vibrio, respectively. The growth medium composition impacted vanadium uptake. Furthermore, pH was also an important factor in the accumulation and localization of vanadium. Most of the vanadium(V) accumulated by these bacteria was converted to less toxic vanadium(IV). Our results provide insights into vanadium accumulation and reduction by bacteria isolated from the ascidian C. robusta to further study the relations between ascidians and microbes and their possible applications for bioremediation or biomineralization.

“…Shewanellae are members of the γ-proteobacteria facultative anaerobes, which were isolated from different environments [ 17 ]. Shewanella species possess good metal bioaccumulation and bioreduction capacities [ 18 , 19 , 20 , 21 ], while information about their biosorption capacity is very limited [ 5 , 22 ].…”

Metal Removal from Nickel-Containing Effluents Using Mineral–Organic Hybrid Adsorbent

Nickel is one of the most dangerous environmental pollutants and its removal from wastewater is an important task. The capacity of a mineral–organic hybrid adsorbent, consisting of Shewanella xiamenensis biofilm and zeolite (clinoptilolite of the Chola deposit), to remove metal ions from nickel-containing batch systems under different experimental conditions was tested. The obtained biosorbent was characterized using neutron activation, SEM, and FTIR techniques. It was established that maximum removal of cations, up to 100%, was achieved at pH 6.0. Several mathematical models were applied to describe the equilibrium and kinetics data. The maximum adsorption capacity of the hybrid biosorbent, calculated using the Langmuir model, varied from 3.6 to 3.9 mg/g. Negative Gibbs energy values and positive ∆H° values indicate the spontaneous and endothermic character of the biosorption process. The effects of several parameters (pH and biosorbent dosage) on Ni(II) removal from real effluent, containing nickel with a concentration of 125 mg/L, were investigated. The optimal pH for Ni(II) removal was 5.0–6.0 and an increase of sorbent dosage from 0.5 to 2.0 led to an increase in Ni(II) removal from 17% to 27%. At two times effluent dilution, maximum Ni(II) removal of 26% was attained at pH 6.0 and sorbent dosage of 1.0 g. A 12-fold effluent dilution resulted in the removal of 72% of Ni(II) at the same pH and sorbent dosage values. The obtained hybrid biosorbent can be used for Ni(II) removal from industrial effluents with low Ni(II) concentrations.
