Concentrations of dissolved gasses measured in the mine waters during 1991 94 [28] and 2001 02 were consistent with mildly reducing conditions (anoxic to suboxic) generally associated with the active biogenic sulfate reduction [e.g. [50, 51]].
Biogenic amines are common biologically active substances extended within the whole animal kingdom where they play vital roles as signal transducer as well as regulator of cell functions.
Generally, in the case of biogenic synthesis, the presence of active chemical groups like amino, sulfhydryl and carboxylic groups plays a key role in reduction of metallic ions and subsequent formation of nano/microparticles.
"If it contains biogenic processes," he says, "that means they were active late into the history of the planet.
In this work, we presented the covalent co-immobilization of a commercial peroxidase and a redox-active protein onto porous silicon and biogenic silica microparticles, for enhancing the operational properties of the resulting biocatalyst.
The underlying architecture of a reef is a biogenic carbonate structure that accretes over many years of active biomineralization by calcifying organisms, including corals and algae2.
Since biogenic nanoparticles are stabilized 'naturally' in the presence of active biomass, their efficacy in the preparation of heterogeneous catalyst was examined.
Amphibian skin granular gland secretions are consistently recognized as rich sources of multiple biologically active compounds [1], such as antimicrobial peptides (AMPs) [2], bradykinins, biogenic amines, complex alkaloids, etc.
Here, we observed that the biomass-supported catalyst proved to be a sturdy substitute for catalyst matrix as biogenic nanoparticles tend to adhere/adsorb to the biomaterial matrix because of certain active chemical groups, which in turn may impart additional stability to the biocatalyst framework.
ChREBPα increased the expression and activity of Nrf2, initiating antioxidant and mitochondrial biogenic programs.
