No significant difference (p > 0.05) was observed in the specific aminopeptidase activity (SAA) developed by Pseudomonas fluorescens, P. putida and Flavobacterium odoratum either growing at pH 5.0-6.5 or at 7 and 12 degrees C. Nevertheless, a significant difference was found when comparing the SAA of these organisms. The SAA of F. odoratum was lower than those of pseudomonads. The 4-nitroaniline test is reliable to estimate the G(-) load of fresh food products.
荧光假单胞菌、恶臭假单胞菌和芳香黄杆菌在pH 5.0 - 6.5或7℃及12℃下生长时，其产生的特异性氨肽酶活性（SAA）未观察到显著差异（p > 0.05）。然而，在比较这些微生物的SAA时发现了显著差异。芳香黄杆菌的SAA低于假单胞菌的SAA。4-硝基苯胺试验可可靠地估计新鲜食品的G(-)负荷。
