Organophosphonates revealed: new insights into the microbial metabolism of ancient molecules
Advances in the understanding of the biochemistry and genetics of microbial phosphonate metabolism are reviewed, and the role of these compounds and of the organisms engaged in their turnover within the P cycle are discussed.

It is found that substances known to disorder cellular macromolecules (chaotropes) did expand microbial growth windows, fungi preferentially accumulated chaotropic metabolites at low temperature, and chemical activities of solutes determined microbial survival at extremes of temperature as well as pressure.

Biological Phosphorus Removal During High-Rate, Low-Temperature, Anaerobic Digestion of Wastewater
The possibility of efficient phosphate removal and recovery from wastewater during AD would represent a major advance in the scope for widespread application of anaerobic wastewater treatment technologies.
Microbial transformations in phosphonate biosynthesis and catabolism, and their importance in nutrient cycling.
The potential for polyphosphate metabolism in Archaea and anaerobic polyphosphate formation in Methanosarcina mazei
It is reported that homologs of bacterial polyP metabolism proteins are present across the major taxa in the Archaea, suggesting that archaeal populations may have a greater contribution to global phosphorus cycling than has previously been recognised.
Phosphate insensitive aminophosphonate mineralisation within oceanic nutrient cycles
It is shown, for the first time, that bacteria isolated from marine samples have the ability to mineralise 2-aminoethylphosphonate, the most common biogenic marine aminophosphonates, via substrate-inducible gene regulation rather than via Pho-regulated metabolism.
