摘要：

Eight brands of domestic and imported bottled water were microbiologically analysed within three hours of purchase at a local supermarket. Viable numbers of microorganisms were estimated on Plate Count Agar (PCA) and PCA diluted to quarter and tenth strengths (1/4 PCA and 1/10 PCA) and incubated at temperatures of 10, 15, 25 and 37 degrees C. Plate count agar diluted to 1/4 and 1/10 incubated at 25 degrees C yielded the highest initial counts, up to 10(4) cfu ml(-1). Pseudomonas spp. was the predominant species. After 6 months of storage at room temperature (18-25 degrees C), few quantitative and qualitative differences were found in the microflora. (C) 1999 Elsevier Science B.V. All rights reserved.
