Abstract
PURPOSE: To obtain an antifoaming agent for fermentation having improved foam lessening properties, foam suppressing properties, and extremely low inhibiting actions on microorganisms, by comprising a compound otained by adding an alkylene oxide to a monofunctional alcohol as a main ingredient.
CONSTITUTION: An antifoaming agent comprising a compound shown by the formula (R is 1W24C alkyl or alkenyl; l is integer of 1W10; m is 10W80, preferably 10W60; n is integer of 0W20, preferably 0W10; a is integer of 3 or 4 and both may be present together in the molecule; A is H or 10W20C fatty acid residue and the molecular weight of polyoxythylene part is ≤25wt% based on total molecular weight) as a main ingredient, and usually about 0.001W1.0wt% antifoaming agent is added to a medium.
