Extremely oligotrophic and complex carbon degrading microaerobic bacteria from Arabian Sea oxygen minimum zone sediments

The paper isolates and characterizes aerobic bacteria from Arabian Sea sediments, showing their ability to degrade complex organic matter under low oxygen conditions and maintain populations in oligotrophic environments.

Thermal endurance by a hot-spring-dwelling phylogenetic relative of the mesophilic Paracoccus

This study identifies a thermophilic strain SMMA_5, a phylogenetic relative of Paracoccus, capable of surviving high temperatures and shows how thermal conditioning and environmental solutes enhance its thermal endurance.

Sedimentation rate and organic matter dynamics shape microbiomes across a continental margin

The paper examines how sedimentation rates and organic matter dynamics influence microbiome structure and function in different oxygen minimum zones along the Arabian Sea margin.

Metabolically-active obligate aerobes in anoxic (sulfidic) marine sediments

The paper identifies metabolically-active obligate aerobes in anoxic marine sediments by combining culture-dependent and -independent methods, revealing their survival through cryptic oxygen production.

Molecular mechanism of sulfur chemolithotrophy in the betaproteobacterium Pusillimonas ginsengisoli

This study identifies the molecular mechanism of thiosulfate oxidation in Pusillimonas ginsengisoli, revealing a unique pathway involving tetrathionate and glutathione.

Cryptic role of tetrathionate in the sulfur cycle: A study from Arabian Sea oxygen minimum zone sediments

The paper investigates the role of tetrathionate in the sulfur cycle of Arabian Sea OMZ sediments, revealing its microbial and geochemical sources and transformations.

Two pathways for thiosulfate oxidation in the alphaproteobacterial chemolithotroph Paracoccus thiocyanatus SST

This paper identifies two distinct pathways for thiosulfate oxidation in Paracoccus thiocyanatus SST: a Sox system and a Tetrathionate-Intermediate pathway, with the latter being more efficient for thiosulfate conversion.

Inorganic salts and compatible solutes help mesophilic bacteria inhabit the high temperature waters of a Trans-Himalayan sulfur-borax spring

The paper investigates how inorganic salts and compatible solutes enable mesophilic bacteria to thrive in high-temperature Trans-Himalayan hot springs by stabilizing macromolecules and maintaining cell viability.
