Abstract
Two difficulties are frequently encountered when it is desired to grow pathogenic bacteria with active aeration, namely, foaming and wetting of the exhaust filter. Chemical or mechanical foam-breaking and heating systems can be used to avoid these problems but have many disadvantages. I have used them mainly on large-scale equipment1,2. However, it was found that a basically different approach had to be used for ordinary laboratory equipment. Since the method which has been developed may have wide applications, it will be described below.
