APPLIED MICROBIOLOGY AND BIOTECHNOLOGYNielsen JC, Lino de FS, Rasmussen TG, Thykaer J, Workman CT, Basso TO, et al. Industrial antifoam agents impair ethanol fermentation and induce stress responses in yeast cells. Appl Microbiol Biotechnol. 2017;101:8237-48....
While the preferred non-emulsified hydrophobic silicone antifoam agents used in this invention can be produced without the use of a catalyst, a catalyst can be employed if desired. When employed the catalysts can be any of the well known types heretofore employed in the preparation of antifoam co...
The improved fermentation rate which has been observed appears to arise because the presence of the hop lipids has a positive effect on yeast metabolism. The hop antifoam base can be used in any type of brewing kettle configuration. It is preferably warmed before addition to the kettle to make...
Development of a foam breaker which operates on the principle of rapid acceleration of foam through a nozzle has allowed large鈥恠cale aerobic fermentations to be run without addition of antifoam agents. Fermentations have been investigated over a wide range of aeration levels in which oxygen ...
Process characteristics, such as extensive CO2 generation, poor quality of raw materials, and frequent contaminations, all聽lead to excessive foam formation during fermentations, which is treated with antifoam agents (AFA). In this study, we have investigated the impact of industrial AFA treatments ...

There is still little knowledge about the mechanisms triggering the...
agentsdepressurizationThe fouling effects of yeast fermentation broths of Candida utilis in the presence of various commercial antifoam agents (PPG2000, B5600, and G832) up to 4.0 mL/L were studied, using Millipore polyvinylidene fluoride 0.22-渭m hydrophilic membranes (GVWP), in a stirred-cell ...
