Follow on Google News | On the "shelf life" of water :Hot on the trail of the biostability of water using state-of-the-art DNA and cell analysis
By: PRD Krems (Austria), 9 August 2018 – In order to better understand and assess the quality of ground and spring water, state-of-the- Water is not just H2O when it bubbles up as ground or spring water, for example. It also contains a myriad of microorganisms whose natural habitat is the cool water. Up until now, very little has been known about how the water-based bacterial community develops in ground and source water. It is therefore still difficult to ascertain or predict its potential effect on the quality of the water after it is stored and distributed. At KL Krems, a project funded by the FTI Programme, a programme run by the federal state of Lower Austria, has taken this issue on board and is developing a pioneering combination of processes that are designed to facilitate, for the first time, a comprehensive analysis of the dynamic of water-based bacteria and thus of the associated biochemical key processes when water resources are used. "Ready to go!" FOR AQUASCREEN Prof. Andreas Farnleitner is coordinating the AQUASCREEN project, as it is known. The Head of the Department of Water Quality and Health at KL Krems explains the background to the project: "Existing standard methods to detect microorganisms in ground and spring water are based on principles dating back to the 19th century. These focus mainly on bacteria that pollute the water from the surface rather than water-based bacteria, some of which we know absolutely nothing about. Less than 1% of water-based bacteria can generally be detected using the standard methods. Up until now, therefore, we have known very little about the development of these natural water microbiota and how they can affect the quality of the water over longer periods when it is stored and distributed. A better understanding of these dynamics, including the existing nutrient and environment situation, is necessary to assess and predict the quality of drinking water but also to identify potential health risks." Into the 21st century with AQUASCREEN In cooperation with ICC Water & Health, IFA-Tulln and EVN Wasser GesmbH, a new combination of processes is being developed. This will be able to determine the existence and growth of water-based bacteria more directly and with more accuracy and speed. In order to achieve this, following a simulation of the storage of water, the team will deploy state-of-the- FTI programme supports research The project is supported by the federal state of Lower Austria with funding provided by the FTI Programme, which has an interdisciplinary focus on nutrition, medicine and health. The federal state is thereby making a significant contribution to the further expansion of KL Krems focus on water quality and health. AQUASCREEN can thus build seamlessly on current results generated by NÖ Forschungs- und Bildungsges.m.b.H. (NFB) as part of the AQUASAFE project funded by Science Call 2015. This project develops and refines a new approach to determine the origin of faecal contamination in water. In addition, highly specific, quantitative evidence of minute quantities of genetic material (DNA) from specific human and animal gut bacteria is developed. Thanks to the consistent support of this research work, KL Krems has managed, within a short space of time, to make important contributions to health and quality of life through its research on water quality and health.
