“…Alicyclobacillus acidoterrestris, a gram-positive, thermoacidophilic, spore forming bacterium, is a frequent contaminant of juices and is a common spoilage microorganism in the processing industry. Due to its ability to undergo sporulation in an acidic environment, and to spoil juices by producing undesirable off-flavours (Sokołowska, 2014;Tianli et al, 2014), comprehensive knowledge about the germination of A. acidoter restris spores is of general interest. The germination of A. acido terrestris spores, and their subsequent outgrowth or inactivation, can be induced by external factors such as high hydrostatic pressure (Wuytack et al, 2000;Vercammen et al, 2012;Sokołowska et al, 2013;Porębska et al, 2015a) or supercritical carbon dioxide (Bae et al, 2009;Porębska et al, 2016).…”
