Recovering Critical Elements From Wastewater for Battery Materials: A Review

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Driven by global carbon neutrality goals, the transition toward a circular economy and sustainable resource management has become increasingly imperative. Given the indispensable role of battery technologies in modern energy storage systems, strategic elements such as lithium (Li), cobalt (Co), and nickel (Ni)—identified by the European ...

Turnover of microbial cells, endospores, and organic carbon in ocean margin sediment affected by submarine landslides

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract The turnover rate of microbial cells drops steeply by increasing depth in the seabed, in accordance with the decreasing rate of organic matter mineralization. Bacterial endospore formation and germination may take place concurrently, yet their coupling to the mineralization rates during burial is poorly understood.

Metabolic Flexibility of Sulfate Reducing Bacteria

Frontiers in Microbiology, 2011
Dissimilatory sulfate-reducing prokaryotes (SRB) are a very diverse group of anaerobic bacteria that are omnipresent in nature and play an imperative role in the global cycling of carbon and sulfur.

NADH and NADPH peroxidases as antioxidant defense mechanisms in intestinal sulfate-reducing bacteria

Scientific Reports, 2023
Animal and human feces typically include intestinal sulfate-reducing bacteria (SRB). Hydrogen sulfide and acetate are the end products of their dissimilatory sulfate reduction and may create a synergistic effect. Here, we report NADH and NADPH peroxidase

Bacteriophages in the Rhizosphere: Roles in Nutrient Cycling, Bacterial Community Structure, and Animal‐Mediated Dispersal

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
This review discusses bacteriophages' roles in soil ecosystems, highlighting their impact on nutrient cycling, plant health, and soil remediation, as well as animal‐mediated phage dispersal mechanisms. Overall, while bacteriophages have potential biotechnological applications, their negative effects on microbial functions and nutrient cycling highlight

“Candidatus Thermonerobacter thiotrophicus,” A Non-phototrophic Member of the Bacteroidetes/Chlorobi With Dissimilatory Sulfur Metabolism in Hot Spring Mat Communities

Frontiers in Microbiology, 2019
In this study we present evidence for a novel, thermophilic bacterium with dissimilatory sulfur metabolism, tentatively named “Candidatus Thermonerobacter thiotrophicus,” which is affiliated with the Bacteroides/Ignavibacteria/Chlorobi and which we ...

Microbially driven organic carbon cycling at the land−sea interface: Advances and an integrated study framework

mLife, Volume 5, Issue 3, Page 282-295, June 2026.
Abstract The land−sea interface is a vital component of global biogeochemical cycles, where microorganisms drive the cycling of carbon, nitrogen, and sulfur. This review synthesizes the research progress from representative land−sea interfaces to elucidate how the microbial community structure and metabolic function influence the mobilization ...

Effect of pH on Dissimilatory Sulfate Reduction by Porcine Cecal Microflora

Nihon Chikusan Gakkaiho, 1998
異化型硫酸還元の結果,大腸で発生する硫化水素は生体にとって有害であり,発生を制御する必要が指摘されているが,大腸における硫酸還元菌の生理や生態はあまり知られていない.この実験では,大腸で起こる異化型硫酸還元のpH依存性について知ることを目的とした.ブタ盲腸液より調整した細菌懸濁液をpH4.5から7.4の範囲で14段階に調整した緩衝液中で12時間培養し,発生した硫化水素を定量した.このとき硫酸イオンと電子供与体(乳酸あるいは水素)は十分量供給した.至適pHは乳酸基質の場合6.1～6.4で,水素基質の場合の6.0よりやや高かった.

The Iron-Sulfur Flavoprotein DsrL as NAD(P)H:Acceptor Oxidoreductase in Oxidative and Reductive Dissimilatory Sulfur Metabolism

Frontiers in Microbiology, 2020
DsrAB-type dissimilatory sulfite reductase is a key enzyme of microbial sulfur-dependent energy metabolism. Sulfur oxidizers also contain DsrL, which is essential for sulfur oxidation in Allochromatium vinosum.
