The Prokaryotes
@inproceedings{Wood2014TheP, title={The Prokaryotes}, author={Ann P. Wood}, booktitle={Springer Berlin Heidelberg}, year={2014} }
The family Achromatiaceae (comprising the single genus Achromatium) is a group of morphologically conspicuous, single-celled, free-living, colorless sulfur-oxidizing bacteria which forms a coherent phylogenetic group within the Gammaproteobacteria. They have yet to be grown in laboratory culture, but ecophysiological measurements suggest they gain energy from sulfide oxidation and may use oxygen and/or nitrate as a terminal electron acceptor. Some Achromatium can fix inorganic carbon, but it is…

Genome Mining, Microbial Interactions, and Molecular Networking Reveals New Dibromoalterochromides from Strains of Pseudoalteromonas of Coiba National Park-Panama
- BiologyMarine drugs

The results show that all strains possess BGCs for the production of secondary metabolites, and a considerable number of distinct polyketide synthases (PKS) and NRPS clusters are present in pigmented strains.
Mobile Genetic Elements Drive Antimicrobial Resistance Gene Spread in Pasteurellaceae Species
- BiologyFrontiers in Microbiology
- 2021
The resistome-associated mobilome in 345 publicly available Pasteurellaceae genomes is investigated, finding that MGEs are comparable and dispersed across species and that they also co-occur in genomes, contributing to the family’s ecology via gene transfer.
Differential Impact of rhamnolipids and TWEEN80 on composition and functionality of the gut microbiota in the SHIME system
- BiologybioRxiv
- 2021
The results confirmed previous observations that the effects on the composition and functionality are both emulsifier- and donor dependent and that the rhamnolipids was larger than that of TWEEN80 at similar concentrations, indicating that the former may not necessarily be a safer alternative for the latter.

Unexpected diversity has been uncovered in Achromatium populations and it is now clear that the organism routinely described as Achrom atium oxaliferum actually comprises several distinct AchromAtium spp.
The Unique Role of Intracellular Calcification in the Genus Achromatium
- Environmental Science

It is proposed that this unique adaptation of Achromatium is a means of overcoming a challenge not faced by other giant sulfur bacteria, namely inherently low levels of free sulfide in their sedimentary environment.

It was concluded that A. oxaliferum was related to organisms of the Chromatium assemblage but constituted a novel lineage within this group of bacteria.
Ecophysiological Evidence that Achromatium oxaliferum Is Responsible for the Oxidation of Reduced Sulfur Species to Sulfate in a Freshwater Sediment
- Environmental ScienceApplied and environmental microbiology

Under oxic conditions, rates of sulfate production in the presence of sodium molybdate were found to correlate strongly with the number of cells added to sediment cores, providing further evidence for a role for A. oxaliferum in the oxidation of reduced sulfur.

Natural Communities of Achromatium oxaliferum Comprise Genetically, Morphologically, and Ecologically Distinct Subpopulations
- Biology, Environmental ScienceApplied and Environmental Microbiology

The distribution of different subpopulations of Achromatium in relation to sediment redox profiles indicated that the genetically and morphologically distinct organisms that coexisted in a single sediment were also ecologically distinct and were adapted to different redox conditions.
