Drinking Water Distribution Systems

Biofilms have been extensively characterised within drinking water distribution systems. However, the significance of materials on biofilm species diversity is not established. This study investigated the community composition of biofilms on plumbing materials receiving filtered and unfiltered water supplies. Biofilms were extracted from polybutylene, polyethylene, cross-linked polyethylene, unplasticised polyvinyl chloride and copper tubes in sampling rigs receiving Murray-Onkaparinga water before or after filtration. Biofilms were extracted and analysed for fatty acid composition using the FAME™ methodology. There were differences in the fatty acid profiles of biofilms and the respective water supplies, indicating differences in the attached and planktonic communities. The results also showed significant differences in the fatty acid profiles of biofilms on the polymer materials compared to copper, suggesting variations in biofilm populations on the different materials. The potential for materials to select for microbial populations has significant implications for the ecology of drinking water biofilms.

Abstract There is evidence that algae can be a sustainable alternative of omega-3 polyunsaturated fatty acids (w-3 PUFA; DHA and EPA) in the diets of felines, but more information is needed to determine bioavailability of algal w-3 PUFAs in felines. Therefore, the objective of this study was to determine the effects of dietary supplementation of algae DHA on plasma and red blood cell (RBC) membrane fatty acid profiles and fecal microbiota of adult cats. A complete randomized design was utilized with thirty female and male adult cats (mean age: 1.8 ± 0.03 yr, mean BW: 4.5 ± 0.8 kg) which were fed an assigned diet for 90 d. Three diets were formulated with poultry fat alone or inclusion of 2% fish oil or 2% algae DHA meal. Blood samples were collected after fasting on 0, 30, 60 and 90 d to be analyzed for plasma and red blood cell fatty acid profiles. A fresh fecal sample was collected within 15 min of defecation from each cat to be analyzed for fecal microbiota. Illumina 16S rRNA sequencing from V4 region was completed using MiSeq and analyzed using QIIME 2. Plasma and RBC fatty acid concentrations at baseline were similar among all cats and treatment groups. However, dietary treatment had a significant effect on the concentrations of several fatty acids in plasma and RBC over time. Plasma and RBC concentrations of DHA were greater (P < 0.05) for cats fed the algal DHA diet compared to the control and fish oil diets. Conversely, plasma and RBC concentrations of EPA did not differ among treatments when analyzed as a change from baseline. Beta- and alpha-diversity did not differ among treatments, indicating that 2% fish oil or algal-DHA meal does alter fecal microbiota of cats in contrast with cats fed a poultry fat-based diet.

AbstractThe aim of this study was to simulate olive oil use and to monitor changes in the profile of fatty acids in home-made preparations using olive oil, which involve repeated heat treatment cycles. The material used in the experiment consisted of extra virgin and refined olive oil samples. Fatty acid profiles of olive oil samples were monitored after each heating cycle (10 min). The outcomes showed that cycles of heat treatment cause significant (p < 0.05) differences in the fatty acid profile of olive oil. A similar trend of differences (p < 0.05) was found between fatty acid profiles in extra virgin and refined olive oils. As expected, the main differences occurred in monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs). Cross-correlation analysis also showed differences between the fatty acid profiles. The most prolific changes were observed between the control samples and the heated (at 180°C) samples of refined olive oil in PUFAs, though a heating temperature of 220°C resulted in similar decrease in MUFAs and PUFAs, in both extra virgin and refined olive oil samples. The study showed differences in fatty acid profiles that can occur during the culinary heating of olive oil. Furthermore, the study indicated that culinary heating of extra virgin olive oil produced results similar to those of the refined olive oil heating at a lower temperature below 180°C.
