During this gut transit, the soil organic matter is strongly modified in terms of nature (organic matter concentration, fulvic and humic acid ratio) and organization (formation of organo-mineral complexes with clay).
This effect increased the formation of organo-mineral complexes and reduced the content of allophane-imogolite-like precursors (e.g., non-crystalline Si and Al).
With increasing Al concentrations, mineralization was reduced up to 80%, accompanied by the formation of organo-mineral complexes, as indicated by infrared analysis.
The formation of mineral scale is a complex problem during the oilfield operations.
This may be explained by the formation of mineral-phytic acid complexes, plus the negligible amount of endogenous phytase production in mammals.
That fetuin-A is indeed involved in the formation and clearance of the mineral complexes has been elegantly established by observations on fetuin-A knockout mice, shown to spontaneously develop ectopic calcification of soft tissues [91].
The fraction of plant biomass returned to soil is transformed into more stable humic substances and contributed to the formation of different organo-mineral complexes and microaggregates which protect soil carbon for further mineralization and increase C sequestration (Lal 2016).
In Figure 16A, saliva NLP were inoculated into DMEM without serum for 1 day (lane 1), 2 days (lane 2), and 14 days (lane 3), which showed a gradual fading of the protein bands, probably due to the formation and enrichment of protein-free mineral complexes.
A mechanism of mineral formation involving a change from one mineral to another is called transformation and can be distinguished from neoformation, which implies a mechanism for the formation of minerals from solution.
Tannins are uniquely characterized from other phenolic compounds by their ability to precipitate proteins from solutions to other macromolecules such as starch, cellulose, and minerals through formation of strong complexes with them (Lekha and Lonsane 1997; Aguilar et al. 2007).
