Development of space technology for ecological habitats [PDF]

open access: yes, 1986
The development of closed ecological systems for space stations is discussed. Growth chambers, control systems, microgravity, ecosystem stability, lighting equipment, and waste processing systems are among the topics ...

A minimal cellulosome‐like system in Cellulosilyticum lentocellum

open access: yesFEBS Open Bio, EarlyView.
Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

Microplastic Accumulation and Risk Assessment in Closed Biofloc Aquaculture: Integrating Biofloc Engineering with Artificial Neural Networks (ANN) Modeling [PDF]

open access: yesPollution
Microplastics (MPs) are pervasive contaminants in closed aquaculture systems, where limited water exchange restricts removal. This study assessed biofloc as a mitigation strategy for polyethylene (PE) MPs and characterized MPs in terms of morphology ...

On the Way to Mars—Flagellated Algae in Bioregenerative Life Support Systems Under Microgravity Conditions

open access: yesFrontiers in Plant Science, 2020
For long-term manned interplanetary missions it is not feasible to carry the necessary oxygen, food, and water to sustain the astronauts. In addition, the CO2 exhaled by the astronauts has to be removed from the cabin air.

Ecological engineering for controlling water pollution in Latin America [PDF]

open access: yes, 2013
Ecological engineering is a discipline that combines ecology and engineering to design, construct, restore and manage ecosystems. The design of constructed wetlands (CWs) and anaerobic digesters (ADs) are two applications of ecological engineering to ...

Characterization of the key membrane protein cytochrome Cyc2 from Ghiorsea bivora

open access: yesFEBS Open Bio, EarlyView.
This study reports the first detailed biochemical analysis of Cyc2TAG1_1, a cytochrome protein involved in microbial iron oxidation. We produced and purified this enzyme in E. coli, then measured its iron‐oxidizing efficiency, and characterized its electrical and structural properties.

Methodology of Calculating Cost of Sustainable Business-Processes Dealing with Solid Municipal Waste Treatment

open access: yesВестник Российского экономического университета имени Г. В. Плеханова, 2022
The article studies the problem of calculating the cost of business-processes of treating solid municipal waste (SMW) in conditions of shaping closed-cycle economy.

Modeling of biotic cycle formation in closed ecological systems

open access: yesIOP Conference Series: Materials Science and Engineering, 2020
Abstract The biotic turnover formation in closed ecological system (CES) is analyzed by means of mathematical and computer modeling. The model CES hierarchical structure formation is ruled by the energy flow through the ecosystem which increases after the introduction of a predator in the steady state of “production - reduction” systems.

Dryland Social-Ecological Systems in Australia [PDF]

open access: yes
Dryland social-ecological systems in Australia are characterized by a water-limited climate, vulnerable terrestrial ecosystems, advanced ecosystem management, and the highest average wealth. Dryland social-ecological systems in Australia have been facing
