Phosphate limitation intensifies
WebMicrobial growth is often limited by key nutrients like phosphorus (P) across the global ocean. A major response to P limitation is the replacement of membrane phospholipids with non-P lipids to reduce their cellular P quota. However, the biological “costs” of lipid remodeling are largely unknown. WebOct 8, 2024 · In the pentose phosphate pathway, there was an opposite effect of shading on gluconate under P sufficiency and deficiency. On the other hand, P limitation increased …

WebAug 30, 2024 · Phosphorus limitations are considered to become severe when the upward phosphate supply is weakened by increased ocean stratification caused by global warming. Thus, the limiting nutrients for nitrogen fixation vary among regions, and the response of nitrogen fixation to environmental changes is not uniform in the ocean. Key Points WebNov 30, 2024 · Moreover, under phosphate- limited conditions (decreased phosphate or in the absence of inorganic phosphate addition), CoQ 10 production increased significantly by 12% to220 mg/L, biomass decreased by 12%, and the CoQ 10 productivity of unit cells increased by 27%. In subsequent fed-batch fermentation, CoQ 10 production reached 272 …
WebNov 8, 2024 · Here, we use phosphate-limited chemostat experiments to show that acidification enhanced phosphorus demands and decreased phosphorus-specific nitrogen fixation rates in Trichodesmium . The increased phosphorus requirements were attributed primarily to elevated cellular polyphosphate contents, likely for maintaining cytosolic pH … WebOct 1, 2009 · The phosphate-specific transport operon pstS3-pstC2-pstA1 was induced during phosphate starvation and its expression was dependent on the 2-component regulatory system SenX3-RegX3. The MTB gene regX3 appears to be essential for bacillary survival during phosphate limitation and in mammalian lungs. Our data suggest that MTB …
WebPhosphate limitation was chosen because it is a common environmental condition encountered in many marine systems [28–30], and it has been described to have a significant effect on primary and secondary metabolism [31,32]. We report here the astonishing diversity of the exo-metabolome of strain FO-BEG1 and the drastic effect that … WebJan 31, 2008 · Phosphate limitation leads to conversion of PhoR into an activated form in which PhoR is autophosphorylated and transfers a phosphoryl group to PhoB. A return to the repression state occurs during growth shift to a phosphate-rich environment; the activation signal is interrupted by PhoR acting as a phosphatase on phospho-PhoB.
