ABSTRACT


The aim of the
study was to evaluate the effect of fifteen herbs on the growth of Alicyclobacillus
acidoterrestris (A.a.)
. Contrary to our expectations, the majority of the
selected herbs stimulated the A.a. growth. The most efficient in inhibition
of A.a. growth was extract of dog rose, characterized by low antioxidant
activity. Exposition on 10% extract of dog rose fruit or dwarf everlast flower
enabled the reduction of A.a. cells number by about 80% (when compared
with control without herbal extract) after 60 h of culturing. In the same concentration
extracts from nettle leaves diminished the growth by 70%, while roots of liquorice
and angelica by 50%. Although the extracts concentrations applied in the experiments
were too high to become competitive (economic considerations) with chemical disinfectants,
in the many of cases the inhibitory effect was stronger for lower doses of herbs.
It suggest that the further research on the impact of herbal extracts (of concentration
below 1%) on A. acidoterrestris growth is needed. In the presented study,
no correlation between antioxidant potential of examined herbs and their inhibitory
effect on A.a. growth was shown.

Key words: Alicyclobacillus acidoterrestris, antioxidants, growth inhibition, herbal extract, juice spoilage, polyphenols.
