The algae investigated at the center not only produce biofuel, but can also be used to efficiently produce polyacrylonitrile (PAN) fibers. The acidity level is a highly critical factor – if the pH moves outside the desired zone, then the algae tend to flocculate. i CARBON DIOXIDE ABSORPTION USING FRESH WATER ALGAE AND IDENTIFYING POTENTIAL USES OF ALGAL BIOMASS Edmore Kativu A dissertation submitted to the Faculty of Engineering and the Built Environment, Licensee IntechOpen. At present, more number of researches work is in progress globally to develop and commercialize algae-based carbon conversion technology. The results indicate that the selected blue-green algae Oscillatoria can be used for CO2 capture and biomass production, freshwater algae are ideal candidates for CO2 capture, when treated with CO2-rich gas. Composition of exhaust gas from thermal power plants. Our team is growing all the time, so we’re always on the lookout for smart people who want to help us reshape the world of scientific publishing. The rate at which plants absorb CO2 and nutrients depends on the amount of light provided. How? The curtains use the power of algae to absorb carbon dioxide from the air. of India, for its financial support (SSP 7219 and CSC 102). Higher CO2 capture capacity observed in Oscillatoria from 16 to 32 h (Figure 6). The irradiance of the LEDs can be dynamically modulated by the instrument control unit through external computer with software. Provided by Algae take CO2 from the Earth’s atmosphere through photosynthesis in the same way that plants and trees do. You can be assured our editors closely monitor every feedback sent and will take appropriate actions. Gibberellic acid is a plant growth hormone that influences various developmental processes; while, cyanobacteria respond to IAA in a manner analogous to higher plants. Large-scale plants are conceivable in southern Europe and North Africa. As the algae consumes CO2 it produces biomass which can be harvested and used to create fuel, oils, high protein food sources, fertilizers and plastics. His newest contribution to the world is a microalgae lamp that will absorb a ton of carbon from the air every year. CO2 is one of the essential components required to grow algae, along with sunlight, water and nutrients. Carbon fibers can be deployed to produce lightweight and high-strength materials that. Not all algae species can absorb CO 2 with the same efficiency, and not all algae grow equally fast. In the process of photosynthesis – plants or trees use energy from the sun to turn carbon dioxide into oxygen – here, the aquatic plant algae suck up carbon dioxide, water, and sunlight to grow and produce energy. The straight, unbranched, filaments are dark blue-green, covered with a thin hyaline sheath and is not attenuated or capitated at the end. The reactor uses a specific strain of algae called chlorella vulgaris, which is claimed to soak up much more CO2 than any other plant. By making research easy to access, and puts the academic needs of the researchers before the business interests of publishers. They are not dependent on agricultural land, fertilisation or freshwater. high dependency on fossil fuels. By Axel Barrett February 11, 2020 February 11, 2020. The largest source of greenhouse gas emissions from human activities in the world is burning fossil fuels for electricity, heat, transportation, and domestic uses. © 2019 The Author(s). Algae-based CO2 conversion is a cost-effective option for reducing carbon footprint. Afterward, luxuriant growth was observed in Vitamin B1, good growth was observed in Vitamin B12, and moderate in Vitamin C. Vitamin B12 acts as a growth factor for all algae as well as higher plants. Energy-Efficient Carbon Fiber Production with Concentrated Solar Power: Process Design and Techno-economic Analysis, Industrial & Engineering Chemistry Research (2018). Poletto went on to explain why micro algae were useful for the system. Available from: Experimental study on CO2 capture for petrochemical industry and thermal power plants, Industrial Biotechnology and Waste Utilization, CSIR-Central Institute of Mining and Fuel Research, Dhanbad, India. Photo-bioreactor FMT 150 used in the present study consists of an algal-cultivation vessel with a sealable lid and a base box containing electronics circuitry, LED light panel, and other components essential for the optimal operation of the photo-bioreactor (Figure 3). "The light can be from the sun, or in this case, artificial light. While chemical and physical means exist to capture CO2 from smoke stack emissions, the cost of utilizing these technologies would result in a significant increase in the cost of power. Potassium is a major cell electrolyte, used for balancing the ionic charge. CO2 is inevitably created by burning fuels like e.g. Under phototrophic growth conditions, microalgae absorb solar energy, and assimilate CO2 from air and nutrients from aquatic habitats. Composition of exhaust gas from natural gas processing industry, GAIL (PATA). Your opinions are important to us. One advantage of aquatic carbon capture and biomass production systems is the ability to capture CO2 in ponds in a nongaseous form as bicarbonate to fertilize algal growth. The collected algal cells were washed twice with sterile distilled water, and then inoculated into the growth medium. If the challenges associated with algae-based carbon capture technology are addressed successfully, the technology will present a solution not only to the global warming problem, but also to reduce the fossil fuel demand. In recent years, cultivation of microalgae has received renewed attention on account of its possibility as a feasible CO2 sequestration technology. Brück now plans to further improve the algae technology. 3) Algae Consume CO2 Like any other plant, algae, when grown using sunlight, consume (or absorb) carbon dioxide (CO2) as they grow, releasing oxygen (O2) for the rest of us to breathe. Algae bloom occurs when there is an imbalance in your planted aquarium. DOI: 10.1021/acs.iecr.7b04841, IPCC Special Report on Global Warming of 1.5°C, Chapter 4: Strengthening and implementing the global response; report.ipcc.ch/sr15/pdf/sr15_chapter4.pdf. The increased nutrients result in higher growth and higher biomass of cyanobacteria. Another important field of application could be the construction industry, which accounts for a significant proportion of global carbon dioxide emissions. At the tenth day, moderate growth was observed in SDS while luxuriant growth was observed in Triton-X, Tween-20, and Tween-80 (Tables 5–7). Posted on 23 April 2020. The BG-11 medium was used for algal culture with the composition of (g/L): K2HPO4.3H2O 0.04, NaNO3 1.5, CaCl2.2H2O 0.036, MgSO4.7H2O 0.075, ferric ammonium citrate 0.006, Na2EDTA 0.001, citric acid 0.006, Na2CO3 0.02, pH 7.0. CO2 emitting industries are contributing a major role in the increase of greenhouse gases in the atmosphere for several decades. After pre-cultivation, the algal inoculum reached exponential growth phase. Algae convert carbon dioxide from the atmosphere, power plants or steel processing exhaust into algae oil. The gas is bubbled into our innovative fully-sealed microalgae cultivation platform that floats on the sea surface. Almost equal growth was observed (visually) up to 7 days. Different process parameters were optimized such as pH, light and temperature, nutrient media, culture condition, inoculum volume, inoculum concentration, etc. "Plants which together would cover the size of Algeria would offset all CO2 emissions from air transport. ++: moderate growth; +: mild growth. The stock culture and inoculum were grown in BG11 medium [3] in the required condition. Greenhouse gas emissions by industries and human activities make the planet warmer. CO2 Absorbing Fabrics. Its front and back windows are made of glass plates. *IAA: Indole-3-acetic acid; **GA: Gibberellic acid. Growth of Oscillatoria in different surfactants.
