General description

Antifoam Y-30 Emulsion is an aqueous emulsion containing 30% active silicon. It contains non-ionic emulsifiers different from those in Antifoam Emulsions B and C. It is designed to control foam in aqueous systems.
Antifoam is also known as defoamer. It is a chemical additive that reduces and hinders the formation of foam in industrial process liquids. It is used to prevent formation of foam or is added to break foam that is already formed.

Application

Antifoam Y-30 Emulsion is used for the following applications:
  • Chemostat cultivation.
  • Cultivation conditions, such as Fed-batch fermentation.
  • Bacterial strains and growth conditions (used in all aerosol experiments).

Other Notes

A 30% aqueous emulsion of Antifoam A concentrate.

Linkage

More easily dispersed in aqueous systems than Antifoam A concentrate.

The synthesis and assembly of the active site [FeFe] unit of [FeFe]-hydrogenases require at least three maturases. The radical S-adenosyl-l-methionine HydG, the best characterized of these proteins, is responsible for the synthesis of the hydrogenase CO and CN(-) ligands from
