The UV dose-response profiles of two isolated organisms, Flavobacterium succinicans and Sphingopyxis chilensis, were determined. S. chilensis has a UV dose-response with potential for use as an indigenous surrogate for Cryptosporidium inactivation, up to 2.2-logs in the dose range 2-7 mJ/cm(2) of monochromatic UV light at 253.7 nm. F. succinicans was more sensitive and tailing was observed above 4 mJ/cm(2) making it unsuitable for UV dose verification above this dose. As a single species in the water samples used in this study, S. chilensis is unlikely to be present in sufficient numbers for routine use as an indigenous surrogate. However, the Sphingomonadaceae family to which it belongs is abundant in various drinking water sources and warrants further investigation.

AB - The prevalence of microorganisms in full-scale water supply systems raises concerns about their pathogenicity and threats to public health. Clean tap water is essential for public health safety. The conditions of the water treatment process from the source water to tap water, including source water quality, water treatment processes, the drinking water distribution system (DWDS), and building water supply systems (BWSSs) in buildings, greatly influence the bacterial community in tap water. Given the importance of drinking water biosafety, the study of microbial diversity from source water to tap water is essential. With the development of molecular biology methods and bioinformatics in recent years, sequencing technology has been applied to study bacterial communities in full-scale water supply systems. In this paper, changes in the bacterial community and the influence of each treatment stage on microbial diversity in full-scale water supply systems are classified and analyzed. Microbial traceability analysis and control are discussed, and suggestions for future drinking water biosafety research and its prospects are proposed. © The Royal Society of Chemistry 2021.

Variability of microbial communities was assessed by cultivation-based [nitrifying, denitrifying most probable number (MPN) heterotrophic plate count] and sequence-aided terminal restriction fragment length polymorphism (T-RFLP) analysis. The effect of microbial community composition on nitrifying MPN values was revealed. The non-treated well water samples showed remarkable differences to their corresponding distribution systems regarding low plate count, nitrifying MPN, and the composition of microbial communities, which increased and changed, respectively, in distribution systems. Environmental factors, such as pH, total inorganic nitrogen content (ammonium and nitrite concentration), and chlorine dioxide treatment had effect on microbial community compositions. The revealed heterogeneous nitrifying population achieved remarkable nitrification, which occurred at low ammonium concentration (14-51 mu M) and slightly alkaline pH 7.7-7.9 in chlorine dioxide disinfected water networks. No change was observed in nitrification-generated nitrate concentration, although nitrate- reducing (and denitrifying) bacteria were present with low MPN and characterized by sequence-aided T-RFLP. The community structures of water samples partially changed in nitrifying enrichments and had influence on the generated nitrifying, especially nitrite-oxidizing MPN regarding the facilitated growth of nitrate-reducing bacteria and even methanogenic archaea beside ammonia-oxidizing microorganisms and nitrite-oxidizing bacteria.

The straight-rod-shaped cells stained Gram-negative, were aerobic and non-motile. Phylogenetic analysis of the 16S rRNA gene sequence of strain PYM3-14(T) revealed a clear affiliation with members of the family Xanthomonadaceae within the class Gammaproteobacteria. The 16S rRNA gene sequence of strain PYM3-14(T) showed the closest sequence similarities to Arenimonas daechungensis CH15-1(T) (96.2 %), Arenimonas oryziterrae YC6267(T) (95.2 %) and Lysobacter brunescens UASM D-T (94.4%). The DNA G+C content of strain PYM3-14(T), measured by two different methods (52.0 mol% and 55.9 mol%, respectively), was much lower than that of any member of the genus Arenimonas. The predominant fatty acids (>8%) were iso-C-16:0, iso-C-15:0, iso-C-14:0, iso-C-17:1 omega 9c and C-16:1 omega 7c alcohol. Strain PYM3-14(T) contained Q-8 as the major ubiquinone and phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and phosphatidylmonomethylethanolamine as the major polar lipids. According to phenotypic and genotypic data strain PYM3-14(T) represents a novel species of the genus Arenimonas, for which the name Arenimonas sub flava sp. nov. is proposed. The type strain is PYM3-14(T) (=NCAIM B 02508(T)=DSM 25526(T)). On the basis of new data obtained in this study, an emended description of the genus Arenimonas is also proposed.
