General description

Antifoam Y-30 is a silicone-based product used to prevent or minimize foaming in both microbial fermentation systems and mammalian suspension cultures. Control of foaming minimizes damage to the cells, resulting in increased protein/antibody production.

Application

Suitable for preventing or minimizing foaming in microbial fermentation systems and mammalian suspension cultures.

Components

Antifoam Y-30 is an aqueous emulsion containing 30% active silicon and non-ionic emulsifiers .

Preparation Note

Antifoam Y-30 can be pre-diluted with 3-10 parts of cool water to aid in dispersion. Pre-diluted suspensions should be used immediately.

Storage Class Code

10 - Combustible liquids

Ultrafiltration (UF) is increasingly being recognized as a potentially effective procedure for concentrating and recovering microbes from large volumes of water and treated wastewater. Because of their very small pore sizes, UF membranes are capable of simultaneously concentrating viruses, bacteria

Enterohemorrhagic Escherichia coli O157:H7 (EHEC O157:H7) outbreaks have revealed the need for improved analytical techniques for environmental samples. Ultrafiltration (UF) is increasingly recognized as an effective procedure for concentrating and recovering microbes from large volumes of water and treated wastewater.

Dead-end ultrafiltration (DEUF) is an alternative approach to tangential-flow hollow-fiber ultrafiltration that can be readily employed under field conditions to recover microbes from water. The hydraulics of DEUF and microbe recovery for a new DEUF method were investigated using 100-liter

Among its attributes, the mythical philosopher's stone is supposedly capable of turning base metals to gold or silver. In an analogous fashion, we are finding that protein crystallization optimization using ionic liquids (ILs) often results in the conversion of base
