The phrase "in life support systems" is correct and usable in written English.
It can be used when discussing medical technology, engineering, or systems designed to sustain life in critical situations.
Example: "The research focused on improving the efficiency of in life support systems for patients in intensive care units."
Alternatives: "in vital support systems" or "in life-sustaining systems."
Concerning the support of human life in closed habitat, we can, conventionally, divide microorganisms, acting in life support system (LSS) into three groups: useful, neutral and harmful.
Due to this character, it may be an excellent algae strain to be applied in life support system for oxygen production in spacecraft or submarine.
More than 80% of terrestrial greenhouse epidemics are due to the fungal genera Phytophthora, Pythium and Fusarium, which have been found in life support system test-beds.
"The environment is completely different, and due to the extreme cold there you could find large amounts of water-ice and other chemistry which is on the surface, and which we could access and use as rocket fuel or in life-support systems to support future human missions we think will go to these locations".
To obtain basic data for adequate air circulation for promoting plant growth in closed plant production modules in bioregenerative life support systems in space, effects of air velocities ranging from 0.1 to 0.8 m s−1 on photosynthesis in tomato seedlings canopies were investigated under atmospheric CO2 concentrations of 0.4 and 0.8 mmol mol−1.
High levels of hydrated sulfate minerals in regolith on Mars used in bioregenerative life support systems will lead to exposure of plant roots to supra-optimal concentrations of both Mg2+ and SO42− ions in the soil solution.
There is a possibility such a situation could occur in Bioregenerative Life Support Systems under microgravity conditions in space because there will be little natural convective or thermal mixing.
In microgravity, one of the major challenge encountered in biological life support systems (BLSS) is the gas liquid transfer with, for instance, the necessity to provide CO2 (carbon source, pH control) and to recover the evolved O2 in photobioreactors used as atmosphere bioregenerative systems.
It is essential to understand why the intensity of production processes is limited at higher irradiation levels and to overcome the factors responsible for this, so that the soil-like substrate could have an even better chance in the competition for the best plant cultivation technology to be used in biological life support systems.
