In the brewing environment, there are a few microorganisms
capable of growing in and deteriorating beer. Four industry
isolates were found to be most common in the formation of
biofilm in beer dispensing and brewing environments. These
include Acetobacter lovaniensis, Wickerhamomyces anomalus,
Lactobacillus brevis, and Pseudomonas aeruginosa. The
presence of these beer spoilers gives insight into the hygiene
conditions of a brewery or dispensing system. Biofilm growth
is common on equipment components and in niches that are
difficult to clean. They come in contact with the product and
provide ideal growth conditions for a multitude of germs that
affect flavor, aroma, and the overall quality of beer. Utilizing a
breakthrough in silver ion technology, a newly developed PVCfree
tubing co-extruded with a silver lining has been verified to
be effective against these top four beer-spoiling bacteria and the
growth of biofilm. Third-party test results have proven that this
new innovation is capable of reducing the concentration of all
the selected biofilm microorganisms by up to 100% over a 24
hr test period.
