Drink this, not that. This experiment tested performance of an environmental water monitoring instrument that does not use preservatives in microgravity. The instrument measures changes in luminescence intensity of a microbe as it interacts with substances in a sample and compares that against a standard. Results of the first round of the experiment were used to improve water sampling techniques, and researchers developed recommendations for using the device to monitor water toxicity aboard the station. Analysis of samples from the station and control samples on the ground produced largely similar results.

Experiment Description

Research Overview
Information Pending

Description
Verification of the characteristics of environmental monitoring of instrument Biotoks-10A intended for an integrated assessment of toxicity of the solutions and water with no conserving agents under microgravity conditions by means of measuring variation in luminescence intensity of microbial biosensor Ekolum during its interaction with the substances contained by a sample under test as compared with a standard measuring instrument and by comparing the findings with similar results produced under ground conditions. Development of the recommendations for nominal use of this device (or certification of this instrument as a nominal one) for on-line determination of the water integrated toxicity on the ISS RS.

Operations

Operational Requirements
Instrument Biotoks-10K, Video camera SONY DVCam, samples of the water recovered from atmospheric water condensate after the ISS SR purification units prior to conserving agent Ag+ being introduced, water samples delivered from the ground.

Operational Protocols
Identifying toxicity of water samples through measuring variation in luminescence intensity of microbial biosensor Ekolum during its interaction with the substances contained in a sample under test as compared with a standard measuring instrument. Modifying this instrument to be used under space flight conditions as a nominal equipment for on-line integrated assessment of toxicity of the ISS RS solutions and water.
