Comparative genomics in acid mine drainage biofilm communities reveals metabolic and structural differentiation of co-occurring archaea [PDF]
, 2016 Background Metal sulfide mineral dissolution during bioleaching and acid mine drainage (AMD) formation creates an environment that is inhospitable to most life. Despite dominance by a small number of bacteria, AMD microbial biofilm communities contain a

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes
FEBS Letters, Volume 599, Issue 23, Page 3417-3443, December 2025.Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

Combustion behaviour of some biodesulphurized coals assessed by TGA/DTA [PDF]
, 2009 Thermal analysis, i.e. TGA/DTA is used to study the changes in the combustion behaviour of microbially treated coals. In view of their high sulphur content and industrial significance three samples are under consideration, i.e.

Transposase interaction with the β sliding clamp: Effects on insertion sequence proliferation and transposition rate [PDF]
, 2015 Insertion sequences (ISs) are ubiquitous and abundant mobile genetic elements in prokaryotic genomes. ISs often encode only one protein, the transposase, which catalyzes their transposition.

Environmental Microbiology, Volume 27, Issue 12, December 2025.A neutrophilic Fe(II)‐oxidizing Gallionellaceae was isolated from circumneutral Cu mine drainage. It mediated Fe(III) biomineralization, resulting in pronounced Cu accumulation (up to 2 wt%) within the solid precipitates. ABSTRACT Geomicrobiology of copper (Cu) and iron (Fe) in circumneutral‐pH drainage from a Japanese Cu mine was investigated, with a ...
