  • resistant
  • Besides being preservative resistant, other features that contribute to the spoilage capacity of Z. bailii are: (i) its ability to vigorously ferment hexose sugars (e.g. glucose and fructose), (ii) ability to cause spoilage from an extremely low inoculum (e.g. one viable cell per package of any size), (iii) moderate osmotolerance (in comparison to Zygosaccharomyces rouxii). (wikipedia.org)
  • sensitivity
  • This paper will present an alternative testing approach using a conventional microbial challenge technique that is capable of reducing the test cycle time from four weeks to 14 days without the loss of sensitivity or impeding the predictability of long-term preservative efficacy effects.
