Diversity and guaiacol production of Alicyclobacillus spp. from fruit juice and fruit-based beverages

摘要

Alicyclobacillus acidoterrestris is an acido-thermophilic, spore-forming bacterial species that can spoil acidic fruit juice and fruit-based beverages. The metabolism of taint compounds by this bacterial species has led to its status as a targeted microorganism in the fruit juice industry. This study aims to assess the genetic diversity of Alicyclobacillus spp. including A. acidoterrestris and its correlation to spoilage taint metabolism.
