General description

Antifoam eliminates excessive foaming formed during impingement, due to proteins and/or carbohydrates in the collection medium. Antifoam B emulsion is a silicone based antifoam. Antifoam B emulsion does not affect the growth of bacteria. Antifoam B emulsion functions as an antifoaming agent in shake flask culture of bacteria.

Application

Antifoam B emulsion has been used:
  • to enhance collection efficiency in collection media
  • as a component in stress granule lysis buffer to reduce foaming, in host cell lysis buffer to reduce foaming caused by detergents
  • to improve solubility of antibiotics
  • as a foaming controls in bacterial growth media

Other Notes

A 10% aqueous emulsion of polydimethylsiloxane

Observing organisms that evolve in response to strong selection over very short time scales allows the determination of the molecular mechanisms underlying adaptation. Although dissecting these molecular mechanisms is expensive and time-consuming, general patterns can be detected from repeated experiments
