Table 1 Efficacy of an alkylpyrazine derivative (5-isobutyl-2,3-dimethylpyrazine) against bacteria

From: First evaluation of alkylpyrazine application as a novel method to decrease microbial contaminations in processed meat products

  1. Pure cultures of isolates obtained from processed meat products were incubated in aqueous pyrazine solutions. Combinations of isolates and pyrazine concentrations that led to a 4-log reduction are labeled with ‘+’, while such with lower reduction rates are labeled with ‘−’
