“…Because these bioengineering strategies require the inoculation of engineered microorganisms in extant habitats, this terraformation approach is an intervention scenario that could give rise to new communities. This path towards the use of synthetic biology to modify ecosystems has been gaining momentum, and microbial biotechnology is now a largely unexplored but very promising alternative that has been proposed within the context of bioremediation [39], coral reef restoration [113], dryland preservation [114,115], carbon sequestration [116,117] or biodiversity conservation [37,118] One particular case study involves arid and semiarid ecosystems. These so-called Drylands cover around 45% of emerged lands and host more than one-third of the human population, and they are expanding while being threatened by global warming [119][120][121].…”

The study of ecosystems, both natural and artificial, has historically been mediated by population dynamics theories. In this framework, quantifying population numbers and related variables (associated with metabolism or biological-environmental interactions) plays a central role in measuring and predicting system-level properties. As we move towards advanced technological engineering of cells and organisms, the possibility of bioengineering ecosystems (from the gut microbiome to wildlands) opens several questions that will require quantitative models to find answers. Here, we present a comprehensive survey of quantitative modelling approaches for managing three kinds of synthetic ecosystems, sharing the presence of engineered strains. These include test tube examples of ecosystems hosting a relatively low number of interacting species, mesoscale closed ecosystems (or ecospheres), and macro-scale, engineered ecosystems. The potential outcomes of synthetic ecosystem designs and their limits will be relevant to different disciplines, including biomedical engineering, astrobiology, space exploration and fighting climate change impacts on endangered ecosystems. We propose a space of possible ecosystems that captures this broad range of scenarios and a tentative road map for open problems and further exploration.

“…As shown in Fig. 1, the cynobacteria bio composite can combine with synthetic biology tools to produce carbon capture systems, this technology not only promotes environmental friendliness but also demonstrates economic feasibility and long-term sustainability [7]. The ability of microalgae to fix carbon dioxide through photosynthesis is 10-50 times that of other terrestrial plants [8].…”

In recent years, the application of fixing carbon dioxide (CO2) by using microalgae to reduce greenhouse effects has been considered a promising technology. Most researchers have paid attention to the economic value of this technology in the conversion of CO2 into energy and fuel products without pollution. This article provides the latest progress on the principles and practical applications of microalgae in CO2 capture, including biological products and biofuel products, and also discusses the challenges and solutions faced by microalgae technology and future expectation, which indicate that cynobacteria can help people alleviate energy crises and reduce the environmental issues of global warming by using natural biological animals to ease the pressure on the planet in an environmentally-friendly way. Based on the above introduction of the principles of microalgae technology, the article predicts the development prospects and potential of microalgae technology and proposes methods for the commercialization of microalga.

Cyanobacteria are photosynthetic organisms that play important roles in carbon cycling as well as promising bioproduction chassis. Here, we isolate two novel cyanobacteria, UTEX 3221 and UTEX 3222, from a unique marine environment with naturally elevated CO₂. We describe complete genome sequences for both isolates and, focusing on UTEX 3222 due to its planktonic growth in liquid, characterize biotechnologically-relevant growth and biomass characteristics. UTEX 3222 outpaces other fast-growing model strains on solid medium. It can double every 2.35 hours in a liquid medium and grows to high density (>31g/L biomass dry weight) in batch culture, nearly double that ofSynechococcussp. PCC 11901, whose high-density growth was recently reported. In addition, UTEX 3222 sinks readily, settling more quickly than other fast-growing strains, suggesting improved de-watering of UTEX 3222 biomass. This settling behavior can be explained in part by larger cell volume. These traits may make UTEX 3222 a compelling choice for photosynthetic bioproduction from CO₂. Overall, we find that bio-prospecting in environments with naturally elevated CO₂ may uncover novel CO₂-metabolizing organisms with unique characteristics.
