Chlorinated ethenes are risk drivers at many contaminated sites, and current bioremediation efforts focus on organohalide-respiring
strains to achieve detoxification. We isolated and characterized the first non-
Dehalogenimonas etheniformans” strain GP, capable of metabolic reductive dechlorination of TCE, all DCE isomers, and VC to environmentally benign ethene.
Among endosymbiotic bacterial lineages, few are as intensely studied as
, which include the causative agents of spotted fever, typhus, and anaplasmosis. However, an important subgroup called “
Midichloriaceae” receives little attention despite accounting for a third of the diversity of
and harboring a wide range of bacteria with unique features, like the ability to infect mitochondria.
Biological foaming or scumming is a sludge separation problem that has become the subject of major concern for long-term stable activated sludge operation in decades. Biological foaming was considered induced by foaming bacteria.
A wide array of archaea populate Earth’s extreme environments; therefore, they may play important roles in mediating biogeochemical processes such as iron and sulfur cycling. However, our knowledge of archaeal biology and evolution is still limited considering that the majority of the archaeal diversity is uncultured.
