Aspergillus flavus NRRL 6555 was inoculated onto whole olives and olive paste samples containing variable amounts of either natamycin or potassium sorbate and incubated at 15 degrees, 25 degrees, and 35 degrees C for 7, 14 and 21 days for whole olives and at 15 degrees and 25 degrees C for 8 and 16 days for olive pastes. The initiation time of growth was parallel to the concentrations of either preservatives applied. However, at 15 degrees C, natamycin at 160 and 320 micrograms/g (ppm) completely inhibited the growth of mold on whole olives for 21 days and olive paste for 7 and 15 days, respectively. All levels of potassium sorbate inhibited mold growth at 15 degrees C, but at 25 degrees C, 6000 micrograms/g (ppm) only, delayed growth for 15 days. The extent of growth at the end of the incubation periods was parallel to the temperatures of incubation. The analyses for aflatoxin B1 production in all samples at all levels of preservatives and control were negative.
将黄曲霉NRRL 6555接种到含有不同量游霉素或山梨酸钾的完整橄榄和橄榄酱样品上，在15℃、25℃和35℃下培养，完整橄榄培养7天、14天和21天，橄榄酱在15℃和25℃下培养8天和16天。生长起始时间与所施加的任何一种防腐剂的浓度呈平行关系。然而，在15℃时，160和320微克/克（ppm）的游霉素分别在21天内完全抑制了完整橄榄上霉菌的生长以及在7天和15天内完全抑制了橄榄酱上霉菌的生长。所有水平的山梨酸钾在15℃时均抑制霉菌生长，但在25℃时，仅6000微克/克（ppm）能使生长延迟15天。培养期结束时的生长程度与培养温度呈平行关系。对所有样品在所有防腐剂水平及对照下黄曲霉毒素B1产生情况的分析均为阴性。
