Attempts to control foam production in exopolysaccharide synthesising cultures of Acremonium persicinum in aerobic fermentation with polypropylene glycol (PPG) 2025 led to a marked reduction in yield. Similar effects were seen with polysaccharide producing cultures of Epicoccum purpurascens , but not with Aureobasidium pullulans. The effects of other chemical antifoams on polysaccharide production in A. persicinum were examined, and no inhibition was noticed with any silicone‐based compound.
