Structuration of dense casein suspensions by phosphates …

In milk, caseins, the main proteins, are associated into a casein micelle (100nm) held together with colloidal calciumphosphate (CCP). When CCP is removed by acid precipitation into sodium caseinate (NaCas), the caseins reassemble into smaller particles, the so-called submicelles (10nm). Caseins are highly sensitive to calcium and phosphate ions,used in most applications.

Interplay between genetic regulation of phosphate ...

Bacterial pathogens, including those of humans, animals, and plants, encounter phosphate (Pi)-limiting or Pi-rich environments in the host, depending on the site of infection. The environmental Pi-concentration results in modulation of expression of the Pho regulon that allows bacteria to regulate phosphate assimilation pathways accordingly. In many cases, modulation of Pho regulon expression ...
