Ding J, Xu Y, Tan J, Zhang H, Xiong X, Mei C, Li M, Xie G. How to make lunar soil suitable for cultivation? - A review. THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 948:174603. [PMID: 39002579 DOI: 10.1016/j.scitotenv.2024.174603] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/12/2024] [Revised: 07/05/2024] [Accepted: 07/06/2024] [Indexed: 07/15/2024]
Abstract
The investigation of lunar soil encompasses extensive periods, employs many improvement methods, and has generated several simulants. The improvement of lunar soil has recently garnered growing interest as an aspect of In-Situ Resource Utilization (ISRU) for regolith. It is crucial to clarify the challenges of utilizing lunar soil as a planting substrate to develop more effective techniques. This review presents a comprehensive analysis of research on improving lunar soil properties, highlights the disparities in mineral composition between real lunar soil (also called regolith) and simulated lunar soil, then details their deficiencies as planting substrates. Following an investigation of existing improvement methods, a dilemma of metals、salt precipitation and high pH caused by adding organic matter alone was noted, while the function of microbes (bacteria, algae, and lichens) in improvement processes was assessed. Finally, we present a perspective on future the lunar soil plantable research development based on the Bioregenerative Life Support System (BLSS). This review aims to promote the engineering application of lunar soil improvements and sustainable development. We hope that one day, regolith will enable plants to flourish on the Moon.

Semyonov DA, Degermendzhi AG. Alga-based mathematical model of a life support system closed in oxygen and carbon dioxide. Vavilovskii Zhurnal Genet Selektsii 2023; 27:878-883. [PMID: 38213709 PMCID: PMC10777294 DOI: 10.18699/vjgb-23-101] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2023] [Revised: 09/18/2023] [Accepted: 09/19/2023] [Indexed: 01/13/2024] Open
Abstract
The purpose of the study was to compare quantitative analysis methods used in the early stages of closed-loop system prototyping with modern data analysis approaches. As an example, a mathematical model of the stable coexistence of two microalgae in a mixed flow culture, proposed by Bolsunovsky and Degermendzhi in 1982, is considered. The model is built on the basis of a detailed theoretical description of the interaction between species and substrate (in this case, illumination). The ability to control the species ratio allows you to adjust the assimilation quotient (AQ), that is, the ratio of carbon dioxide absorbed to oxygen released. The problem of controlling the assimilation coefficient of a life support system is still relevant; in modern works, microalgae are considered as promising oxygen generators. At the same time, modern works place emphasis on empirical modeling methods, in particular, on the analysis of big data, and the work does not go beyond the task of managing a monoculture of microalgae. In our work, we pay attention to three results that, in our opinion, successfully complement modern methods. Firstly, the model allows the use of results from experiments with monocultures. Secondly, the model predicts the transformation of data into a form convenient for further analysis, including for calculating AQ. Thirdly, the model allows us to guarantee the stability of the resulting approximation and further refine the solution by small corrections using empirical methods.

Abstract
With the construction of the International Space Station, humans have been continuously living and working in space for 22 years. Microbial studies in space and other extreme environments on Earth have shown the ability for bacteria and fungi to adapt and change compared to "normal" conditions. Some of these changes, like biofilm formation, can impact astronaut health and spacecraft integrity in a negative way, while others, such as a propensity for plastic degradation, can promote self-sufficiency and sustainability in space. With the next era of space exploration upon us, which will see crewed missions to the Moon and Mars in the next 10 years, incorporating microbiology research into planning, decision-making, and mission design will be paramount to ensuring success of these long-duration missions. These can include astronaut microbiome studies to protect against infections, immune system dysfunction and bone deterioration, or biological in situ resource utilization (bISRU) studies that incorporate microbes to act as radiation shields, create electricity and establish robust plant habitats for fresh food and recycling of waste. In this review, information will be presented on the beneficial use of microbes in bioregenerative life support systems, their applicability to bISRU, and their capability to be genetically engineered for biotechnological space applications. In addition, we discuss the negative effect microbes and microbial communities may have on long-duration space travel and provide mitigation strategies to reduce their impact. Utilizing the benefits of microbes, while understanding their limitations, will help us explore deeper into space and develop sustainable human habitats on the Moon, Mars and beyond.

[PMID: 37048115 PMCID: PMC10093652 DOI: 10.3390/cells12071043] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2022] [Revised: 03/24/2023] [Accepted: 03/25/2023] [Indexed: 03/31/2023] Open
Abstract
Microgravity (µg) has a massive impact on the health of space explorers. Microgravity changes the proliferation, differentiation, and growth of cells. As crewed spaceflights into deep space are being planned along with the commercialization of space travelling, researchers have focused on gene regulation in cells and organisms exposed to real (r-) and simulated (s-) µg. In particular, cancer and metastasis research benefits from the findings obtained under µg conditions. Gene regulation is a key factor in a cell or an organism’s ability to sustain life and respond to environmental changes. It is a universal process to control the amount, location, and timing in which genes are expressed. In this review, we provide an overview of µg-induced changes in the numerous mechanisms involved in gene regulation, including regulatory proteins, microRNAs, and the chemical modification of DNA. In particular, we discuss the current knowledge about the impact of microgravity on gene regulation in different types of bacteria, protists, fungi, animals, humans, and cells with a focus on the brain, eye, endothelium, immune system, cartilage, muscle, bone, and various cancers as well as recent findings in plants. Importantly, the obtained data clearly imply that µg experiments can support translational medicine on Earth.

Abstract
Food and nutrition have greatly influenced the effectiveness of space exploration missions. With the development of technology, attention is now being paid more and more to preparing food for the microgravity environment, taking into account factors like nutrient density, shelf life, optimized packaging, preservations, innovations, challenges, and applications. The spectrum of food products is designed to meet the balanced nutritional requirements, reduce hazards encountered by astronauts, and utilize space in explorers during space missions. For the long duration of space missions and, consequently, for human permanence in space, it is crucial to provide humans with an adequate supply of fresh food to meet their nutritional needs. By doing this, astronauts could reduce the health risks associated with psychological stress, microgravity, and radiation exposure from space. Maintaining astronauts' health, happiness, and vitality during long-duration human-crewed missions has recently emerged as an essential and critical research area. The food they eat appears to be an important factor. For short-term space missions, astronauts' food could be brought from earth. Still, for long-term space missions to the Moon, Mars, and other distant missions, which are the current research destinations, they must find a way to eat, such as by cultivating plants or finding other means of survival. Scientists and researchers are attempting to develop novel food production technologies or systems that require minimal inputs while maximizing safe, nutritionally balanced, and delicious food outputs for long-duration space missions that could benefit people on earth. This review summarizes various aspects of space food, including evolution, innovations, technological advancements to prolong shelf life, and astronauts' problems. It also involves current research, including space foods like 3D printing and space farming for a long-term space mission.

Abstract
Microorganisms follow us everywhere, and they will be essential to sustaining long-term human space exploration through applications such as vitamin synthesis, biomining, and more. Establishing a sustainable presence in space therefore requires that we better understand how stress due to the altered physical conditions of spaceflight affects our companion organisms. In microgravity environments such as orbital space stations, microorganisms likely experience the change in gravity primarily through changes in fluid mixing processes. Without sedimentation and density-driven convection, diffusion becomes the primary process governing the movement of growth substrates and wastes for microbial cells in suspension culture. Non-motile cells might therefore develop a substrate-deficient "zone of depletion" and experience stress due to starvation and/or waste build-up. This would in turn impact the concentration-dependent uptake rate of growth substrates and could be the cause of the altered growth rates previously observed in microorganisms in spaceflight and in ground-simulated microgravity. To better understand the extent of these concentration differences and their potential influence on substrate uptake rates, we used both an analytical solution and finite difference method to visualize concentration fields around individual cells. We modeled diffusion, using Fick's Second Law, and nutrient uptake, using Michaelis-Menten kinetics, and assessed how that distribution varies in systems with multiple cells and varied geometries. We determined the radius of the zone of depletion, within which cells had reduced the substrate concentration by 10%, to be 5.04 mm for an individual Escherichia coli cell in the conditions we simulated. However, we saw a synergistic effect with multiple cells near each other: multiple cells in close proximity decreased the surrounding concentration by almost 95% from the initial substrate concentration. Our calculations provide researchers an inside look at suspension culture behavior in the diffusion-limited environment of microgravity at the scale of individual cells.

Abstract
The possibility of life elsewhere in the universe has fascinated humankind for ages. To the best of our knowledge, life, as we know it, is limited to planet Earth; yet current investigation suggests that life might be more common than previously thought. In this review, we explore extreme terrestrial analogue environments in the search for some notable examples of extreme organisms, including overlooked microbial groups such as viruses, fungi, and protists, associated with limits of life on Earth. This knowledge is integral to provide the foundational principles needed to predict what sort of Earth-like organisms we might find in the Solar System and beyond, and to understand the future and origins of life on Earth.

Abstract
Despite the increasing interest in using microbial-based technologies to support human space exploration, many unknowns remain not only on bioprocesses but also on microbial survivability and genetic stability under non-Earth conditions. Here the desert cyanobacterium Chroococcidiopsis sp. CCMEE 029 was investigated for robustness of the repair capability of DNA lesions accumulated under Mars-like conditions (UV radiation and atmosphere) simulated in low Earth orbit using the EXPOSE-R2 facility installed outside the International Space Station. Genomic alterations were determined in a space-derivate of Chroococcidiopsis sp. CCMEE 029 obtained upon reactivation on Earth of the space-exposed cells. Comparative analysis of whole-genome sequences showed no increased variant numbers in the space-derivate compared to triplicates of the reference strain maintained on the ground. This result advanced cyanobacteria-based technologies to support human space exploration.
