“…LEDs provided an opportunity to optimize the spectra for a given plant response and have been used as primary light sources for space-based plant research chambers and bio-regenerative life-support systems, such as plant tissue culture, establishment horticulture, seedling production and zoological experiments (Guo et al, 2008;Stutte, 2009). LEDs had been successfully used to cultivate several plant species, including lettuce Kim et al, 2006;Li and Kubota, 2009;Stutte et al, 2009), pepper (Schuerger et al, 1997), spinach (Yorio et al, 2001), Chinese cabbage (Avercheva et al, 2009), non-heading Chinese cabbage (Li et al, 2012;Fan et al, 2013b), cucumber (Sander et al, 2010), potato (Jao and Fang, 2004), tomato (Liu et al, 2011a;2011b;Fan et al, 2013a), upland cotton (Li et al, 2010), maize (Felker et al, 1995), wheat (Goins et al, 1997), strawberry (Nhut et al, 2003), grape (Poudel et al, 2008), cymbidium (Tanaka et al, 1998), lilium (Lian et al, 2002), marigold and salvia (Heo et al, 2002), chrysanthemum Lund et al, 2007;Kurilcik et al, 2008) and rehmanniae (Hahn et al, 2000).…”

The objective of the present study was to evaluate the effects of different light emitting diodes (LEDs) on growth, photosynthetic characteristic and chloroplast ultrastructure of upland cotton (Gossypium hirsutum L.) seedlings. Seedlings of the cultivar Sumian 22 were grown under seven different lights including blue (B) plus red (R) LEDs BR (1:8, 1:3, 1:1, 3:1), B LEDs, R LEDs and fluorescent lamps (FL) with the 100 μ mol m -2 s -1 photosynthesis photon flux (PPF) and a 12 hour photoperiod for 40 days. Compared with FL, fresh mass, dry mass, root length, stem width, root activity, length of palisade tissue and stomatal frequencies were significantly greater as well as the thickest grana lamella in chloroplast in seedlings grown under BR1:8 LEDs; The chlorophyll a, chlorophyll b, total chlorophyll contents, photosynthetic rate, leaf thickness, spongy tissue length and stomatal areas were highest in seedlings under B LEDs; The stem length, leaf area, sucrose, soluble sugar and starch concentrations were highest as well as the greatest number and volume of starch grains in chloroplast in seedlings under R LEDs. It was suggested that BR1:8 LEDs might be used as a primary light for the cultivation of upland cotton seedlings under controlled conditions.

“…Temperature control is a crucial assumption for our process design, though it remains an unsolved challenge. It could be achieved via reactor jacketing, use of a transparent dome-like structure to trap radiant solar heat akin to a greenhouse 12 , temperature control systems, or some combination thereof 13 . Second, the thinner Martian atmosphere results in higher ionizing and gamma radiation levels reaching the surface as compared to Earth.…”

Designing the bioproduction of Martian rocket propellant via a biotechnology-enabled in situ resource utilization strategy

et al. 2021

Mars colonization demands technological advances to enable the return of humans to Earth. Shipping the propellant and oxygen for a return journey is not viable. Considering the gravitational and atmospheric differences between Mars and Earth, we propose bioproduction of a Mars-specific rocket propellant, 2,3-butanediol (2,3-BDO), from CO2, sunlight and water on Mars via a biotechnology-enabled in situ resource utilization (bio-ISRU) strategy. Photosynthetic cyanobacteria convert Martian CO2 into sugars that are upgraded by engineered Escherichia coli into 2,3-BDO. A state-of-the-art bio-ISRU for 2,3-BDO production uses 32% less power and requires a 2.8-fold higher payload mass than proposed chemical ISRU strategies, and generates 44 tons of excess oxygen to support colonization. Attainable, model-guided biological and materials optimizations result in an optimized bio-ISRU that uses 59% less power and has a 13% lower payload mass, while still generating 20 tons excess oxygen. Addressing the identified challenges will advance prospects for interplanetary space travel.

“…Light emitting diodes (LEDs) are characterized by wavelength specificity and narrow bandwidth, small mass and solid state construction, and long life. They produce minimum heating which makes research on the effects of light quality on microalgal growth and development convenient, accurate and comprehensive (Guo et al, 2008; Shu, Tseng, & Jaiswal, 2018). It is worth mentioning that the light quality in the present study is defined as the spectral distribution of photons, as adopted by previous studies (Li, Li, Liu, & Qin, 2020; Meng, Cui, Wang, & Li, 2018; Romero‐Romero & Sánchez‐Saavedra, 2017; Smith, 1982).…”

The effect of light qualities, for example white light (WL), blue light (BL), red light (RL) and green light (GL), respectively, provided by the LEDs on the growth, pigment content, light absorption and chlorophyll fluorescence parameters of Isochrysis galbana strain IOAC724S was measured. The growth rate of algae exposed to GL was not significantly different from that of WL, but was significantly higher than that of blue light (BL) or red light (RL). These four light colours were all efficiently absorbed by algal cells, with an absorption rate up to 92%-93%. The light absorbed by pigments contributes only part of the light absorbed by cells, ranging from 8.3% (at RL) to 59.7% (at BL). Among the monochromatic light, the highest light absorption was obtained in cells cultivated at BL, but the photochemical reaction was lowered. No positive effect of monochromatic RL was found. Cells cultivated at BL and RL were, respectively, restricted by down-regulated photosynthetic efficiency and sufficient light absorption; meanwhile, GL showed a dramatic increase in photosynthetic efficiency, associated with a light absorption close to that for cells exposed to WL (both at 30.6%), suggesting that GL promotes the photosynthesis of I. galbana by balancing the light absorption and utilization.
