TL;DR: The discovery and cultivation of a completely nitrifying bacterium from the genus Nitrospira, a globally distributed group of nitrite oxidizers, and the genome of this chemolithoautotrophic organism encodes the pathways both for ammonia and nitrite oxidation.

TL;DR: A pure culture of a comammox bacterium is isolated and it is shown that it is adapted to slow growth in oligotrophic and dynamic habitats on the basis of a high affinity for ammonia, low maximum rate of ammonia oxidation, high growth yield compared to canonical nitrifiers, and genomic potential for alternative metabolisms.

TL;DR: In this paper, the effect of an organic nutrient (yeast extract) on biooxidation of a refractory gold-bearing sulfidic concentrate was studied in two bioreactors under continuous conditions and the results suggest that the organic nutrient changed the composition and increased the activity of the microbial population.

TL;DR: A method for leaching rare earth elements from coal ash in the presence of elemental sulfur-oxidizing communities of acidophilic chemolithotrophic microorganisms was proposed and results indicated that scandium, yttrium, and lanthanum were recovered.

TL;DR: In this article, a defined culture constructed from strains of acidophilic chemolithotrophic microorganisms exhibited higher rates of bioleaching than the indigenous culture obtained from the acid mine drainage.
