Antifoam Y-30 Emulsion
aqueous-silicone emulsion
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.
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

Pichia pastoris is a widely used host for recombinant protein production. The foaming associated with culturing it on a large scale is commonly prevented by the addition of chemical antifoaming agents or "antifoams." Unexpectedly, the addition of a range of

BACKGROUND: A temperature limited fed-batch (TLFB) technique is described and used for Pichia pastoris Mut+ strain cultures and compared with the traditional methanol limited fed-batch (MLFB) technique. A recombinant fusion protein composed of a cellulose-binding module (CBM) from Neocallimastix patriciarum
