We reported important environmental drivers of dissolved CH4 concentrations (d-CH4) in nutrient-limited mountainous freshwater a cold-temperate region and explored the potential for multiple known oxic production pathways. Field investigation revealed consistent supersaturated d-CH4 surface water (relative to theoretical value at atmospheric equilibrium), with significant seasonal variations. Statistical analysis highlighted direct impact algal dynamics indirect effect temperature nutrients on d-CH4. Further lab-scale incubation demonstrated that decreased by 55.25 93.65% algae removal, while it increased 4 10 times methylphosphonate (MPn) amendment. These findings argued produced from metabolism related MPn had high It also verified pivotal role cyanobacteria this mechanism, light acting as regulatory factors. Through highlighting characteristics proposing through lakes, study enriches comprehension aquatic cycle warns about importance preserving balance minimal human disturbance.

A bstract Phosphonates (PHTs), organic compounds with a stable C—P bond, are widely distributed in nature. Glyphosate (GP), synthetic PHT, is extensively used agriculture and has been linked to various human health issues environmental damage. Given the prevalence of GP, developing cost-effective, on-site methods for GP detection key assessing pollution reducing exposure risks. We adopted Agrobacterium tumefaciens CHLDO, natural degrader, as source genetic parts constructing PHT biosensors. In this species, phn gene cluster, encoding lyase pathway, regulated by PhnF transcriptional repressor part Pho regulon. selected phnG promoter, which displays dose-dependent response build set whole-cell Through stepwise optimization cascade, we created biosensor capable detecting 0.25-50 μM range samples, including soil water.
