Tetragenococcus halophilus KUD23, a non-histamine producer, was isolated from a traditional Korean high-salt fermented soybean paste, doenjang. The strain was safe in terms of antibiotic susceptibility, hemolytic activity and biofilm formation. It could grow on De Man-Rogosa-Sharpe agar containing 21% (w/v) NaCl, exhibited acid production at 15% NaCl, and had strain-specific proteolytic and lipolytic activities under salt stress. Complete genome analysis of T. halophilus KUD23 and comparative genomic analysis shed light on the genetic background behind these phenotypic characteristics, including non-production of histamine and proteolytic and lipolytic activities.© FEMS 2017.
