Closed Ecological Systems (CES), i.e. biological systems closed to material but open to energy exchange, have been unexplored as biological tools. Only the investigations of bioregenerative Life Support systems For space missions have created some activity. However, these systems also have enormous potential applications on Earth.

Closed Ecological Recirculating Aquaculture Systems
Fisheries Science Series, 2017Closed habitation experiments are essential for global environment improvement and maintenance of self-sustaining ecosystems. Hydro-ecosystems, which utilize aquatic organisms, are a promising prospect in habitation experiments. The utilization of aquatic organisms in closed systems can essentially be divided into three parts: (1) cultivation of ...

Long term life support requires the use of a closed ecological system. The attainable degree of closure is determined by the extent of conversion achieved in the waste recovery system. Organisms used in such systems must be reliable, useful, and integrable.

Technical Review of the Laboratory Biosphere Closed Ecological System Facility
Advances in Space Research, 2004Laboratory Biosphere is a 40 m3 closed life system that commenced operation in May 2002. Light is from 12,000 W of high pressure sodium lamps over planting beds with 5.37 m2 of soil. Water is 100% recycled by collecting condensate from the temperature and humidity control system and mixing with leachate collected from under the planting beds ...

Carbon recycling in materially closed ecological life support systems
Biosystems, 1988Materially closed microbial ecosystems represent model life support systems for the future human habitation of space. These ecosystems when subjected to a constant energy flux seem to be reliable and self-sufficient systems for recycling of biologically produced carbon compounds.

Pressure, O2, and CO2, in Aquatic Closed Ecological Systems
Advances in Space Research, 2013Abstract Pressure increased during net photosynthetic O2 production in the light and decreased during respiratory O2 uptake during the dark in aquatic Closed Ecological Systems (CESs) with small head gas volumes. Because most CO2 will be in the liquid phase as bicarbonate and carbonate anions, and CO2 is more soluble than O2, volumes of gaseous CO2 ...

CLOSED ECOLOGICAL SYSTEMS: FROM THE BIOSPHERE TO LIFE SUPPORT SYSTEMS AND BACK
Вестник Российской академии наук, 2023The paper provides a brief overview of the available facts and ideas about the nature of climate change. Theproblems of ecological research, which are becoming more acute in relation to biosphere research, are considered: this is the problem of data deficit and the problem of the uniqueness of ecosystems.

The legacy of biosphere 2 for the study of biospherics and closed ecological systems
Advances in Space Research, 2003The unprecedented challenges of creating Biosphere 2, the world's first laboratory for biospherics, the study of global ecology and long-term closed ecological system dynamics, led to breakthrough developments in many fields, and a deeper understanding of the opportunities and difficulties of material closure. This paper will review accomplishments and

Safe and Ecological Refluxing with a Closed‐Loop Air Cooling System
ChemSusChem, 2016Abstract Off‐the‐shelf computer cooling hardware was used to construct a closed‐loop air cooling system (CLACS) that is distinguished by scalability, low energy, and no tap water consumption. Constructed to be generally used with laboratory condensers, the system was tested with several common low and high boiling solvents and showed ...
