Phosphate insensitive aminophosphonate mineralisation within oceanic nutrient cycles [PDF]
The ISME Journal, 2018 Abstract Many areas of the ocean are nutrient-poor yet support large microbial populations, leading to intense competition for and recycling of nutrients. Organic phosphonates are frequently found in marine waters, but require specialist enzymes for catabolism.

Environmental Microbiology, Volume 26, Issue 6, June 2024.We sequenced water samples from 44 lakes by shotgun sequencing, followed by binning them into metagenome‐assembled genomes. The genomic information from these genomes along with nutrient measurements was used for phylogenetic and ecological analysis. Abstract Understanding intricate microbial interactions in the environment is crucial.

Physiological and Hemolytic Toxicity of Some Aminophosphonates
Zeitschrift für Naturforschung C, 2001 Abstract The effect of novel synthesized aminophosphonates on membrane potential and electrical conductance of internodal cells of Nitellopsis obtusa and hemolysis of erythrocytes (RBC) was studied. It was found that those the organophosphorous compounds, when present at 10-100 μm concentrations, caused depolarization and increased ...
