The development of microbial communities in biofilms of a drinking water distribution system was monitored, and compared to the microbial communities in water. The microbial communities were studied by phospholipid fatty acid (PLFA) profiles. In drinking water samples the most common PLFAs, with the proportion of 60.9%, were monoenoic fatty acids, such as 16:1ω7c and 18:1ω7c, indicating high abundance of gram-negative bacteria. Instead, in biofilm samples saturated fatty acids, such as 16:0 and 18:0, indicating general biomass, accounted for 54.9–78.4% of the total PLFAs. The proportions of monoenoic fatty acids in biofilm increased from 11.5% to 31.2% with water aging from 22 h to 62 h in the distribution system. In conclusion, water aging affected the structure of microbial communities in biofilms, and the microbes in water differed from those in biofilms. These differences might also reflect the differences in the physiological state of the microbes, which is influenced by water chemistry and by the growth environment, i.e. water or biofilm.
