There are several experimental models of biological life support systems (BLSS) designed to incorporate a chlorella pool. These BLSS can be optimized if populated by algal associations that could take up more functions within the closed cycling system than a single alga species. Introduction of a Spirulina and Chlamydomonas poly-culture with differing in(More)
Goals of the 3-month experiment GREENHOUSE using the equipment of greenhouse SVET (ECO-PSY-95) were to feature growth and development of wheat through the entire cycle of ontogeny under the maximally mimicked MIR environment, and to try out the procedures and timeline of space experiment GREENHOUSE-2 as a part of the fundamental biology investigations(More)
Previous modeling of the human-chlorella-microorganisms system showed that the absolute balance of atmospheric oxygen and carbon dioxide is unattainable because of inequality of the human respiration factor and chlorella assimilation factor. Analysis of patterns of gas-exchange regulation in a system with open trophic human-algae interrelations revealed(More)
The investigation had the aim to evaluate the effects of low doses (< 1-10 cGy) of ionizing radiation on the physical-chemical qualities of high-purification water. It had also the goal to study germination rate and energy and sprouting of four species of higher plants exposed directly and indirectly (watering) to alpha- and beta-radiation from radionuclids(More)
The work was performed in order to evaluate possible negative effect of high temperatures on biological properties of seeds in space experiment BIORISK-MSN-2. Laboratory experiments showed that seeds possess high enough resistance to extended exposure to high temperatures. Results of studying effects of positive temperatures in the region of 40 to 100(More)
Metabolism of sLt during Russian-US experiment GREENHOUSE-2 (July 9, 1996-January 17, 1997) within the MIR/NASA space research program and in laboratory Svet experiments in 1995-1996 was studied. Chemical, biochemical and pigment analyses of the flight and laboratory plants were made after the first (dry biomass) and second vegetation (photosynthetically(More)
We plan to perform space experiments on development of a technology for cultivation of leaf vegetables that might be a component of future life support systems for space crews. For this purpose, we are going to fly research greenhouses with the crop area from 0.03 up to 0.1 m2 inside the universal docking module of the ISS Russian segment. To prepare for(More)
