Houston – We Have a Problem

Published on 09/13/2019 | by Waterline Admin

The International Space Station is brimming with bacteria and fungi that can cause diseases and form biofilms that promote antibiotic resistance, and can even corrode the spacecraft, a new study has found. The station, now over 20 years old, has been visited by more than 222 astronauts and up to six resupply missions a year up until August 2017.

NASA scientists discovered microbes mainly came from humans and were similar to those found in public buildings and offices here on Earth. The study – the first to provide a comprehensive catalogue of the bacteria and fungi lurking on interior surfaces in closed space systems – was published in the journal Microbiome.

Dr Kasthuri Venkateswaran, a senior research scientist at the NASA Jet Propulsion Laboratory and one of the study’s authors, said: “The ISS is a hermetically sealed closed system, subjected to microgravity, radiation, elevated carbon dioxide and the recirculation of air through HEPA filters, and is considered an ‘extreme environment’.” He noted that microbes are known to survive and even thrive in extreme environments. The microbes that are present on the International Space Station “could have been in existence since the station’s inception,” he added, “while others may be introduced every time new astronauts or payloads arrive.”

Venkateswaran said:  “The influence of the indoor microbiome on human health becomes more important for astronauts during flights due to altered immunity associated with space flight and the lack of sophisticated medical interventions that are available on Earth. In light of an upcoming new era of human expansion in the universe, such as future space travel to Mars, the microbiome of the closed space environment needs to be examined thoroughly to identify the types of microorganisms that can accumulate in this unique environment, how long they persist and survive, and their impact on human health and spacecraft infrastructure.”

Product Spotlight

PrimeLab Photometer

The PrimeLab photometer hand-held Bluetooth® device is expandable and portable, developed for ultimate flexibility for use in a range of water systems. With only one light source and the JENCOLOR multi-spectral sensor used exclusively in the PrimeLab, it is possible to measure all water parameters where the water sample is visibly discoloured after addition of a reagent. Key Features of PrimeLab Photometer: The first and only PrimeLab photometer with just 1 LED / 1 JENCOLOR sensor, covering the 400 wavelength (380nm-780nm). More than a 100 different parameters available. Activation of add-on parameters is possible even after purchase. Powerful PC-software and app with free cloud service. Creating reports and dosage recommendations by just a click, using your individual water treatment chemicals.

HuwaSan TR50 Silver Stabilised Hydrogen Peroxide

HuwaSan TR50 is a commercial water disinfectant and biocide designed for shock disinfection or constant dosing. HuwaSan TR50 kills legionella bacteria and in addition removes biofilm. It is safer to use than chlorine as the disinfection breakdown products are oxygen and water. Independent testing shows that HuwaSan TR50 provides a very wide spectrum of biocidal activity against bacteria, viruses, spores, fungi, amoebae (such as amoeba acanthus which can act as a host to legionella bacteria) and algae.

MC1+ Protector

Formulated to prevent wear and tear and the resulting debris, MC1+ stops magnetite and other deposits forming. As it does this, it protects the central heating, keeping the boiler working efficiently and helping to ensure the system lasts for longer.

MM2050 - PT100 Thermometer

Four/three/two wire measurement, Max/min functions, Hold function, Dual display, °C/°F/°A selectable, Simultaneous display of real time and max/min/hold measurement, Self calibrating.

MD610 Photometer

The MD610 gives you a mobile device in a modern design with the analytical features of a laboratory photometer. All important water analysis parameters from A(luminium) to Z(inc) are covered. Combined with the high precision of Lovibond® reagents, a reliable and quick analysis of water samples is guaranteed. Reagent tablets, powder reagents, liquid reagents, or cuvette tests are used depending on the method.

Armitage Shanks Markwik 21

Markwik21

(TB H2a) an integral thermostatic bib mixer tap, single long lever mixer. Single flow fixed horizontal nozzle, sequential operation. Sequential operation ensures both hot and cold supply are purged on each use, long lever gives precise control. Insulated technology keeps the ‘hot’ side of the mixer at a safe surface temperature.

AS Shower chrome

AS Shower chrome

Legionnaires‘ disease is usually spread by the breathing in of water vapour containing Legionella bacteria which is then deposited on the lungs. The bacteria thrives in water temperatures between 25 and 45°C and so showers by their very nature create an ideal environment for the bacteria to spread. The AS SHOWER chrome filter provides reliable and immediate protection against Legionella, removing bacteria at the point of use, allowing users to shower safely.
