This book was released on 2018 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microalgae has been used in research for biodiesel production for many years. The reason for choosing microalgae rather than other lipid containing sources is because algae takes up carbon dioxide, a greenhouse gas and can be cultivated in any harsh condition. In addition to being used as a possible biofuel source, algae is also being used as a potential food source for humans and animals, and a major ingredient in the cosmetic and pharmaceutical industries. Currently another issue that the world faces is disposing of dairy and agricultural wastewater. This research is based on cultivating Chlorella vulgaris (C. vulgaris) in untreated dairy wastewater. This wastewater comes from a local dairy near the university and it contains nutrients which facilitate the growth of C. vulgaris. Using indoor cultivation in a photobioreactor, under artificial light conditions, the growth of C. vulgaris in wastewater was monitored to maximize biomass productivity. The growth rate and biomass concentration were obtained from UV-Vis spectroscopy by determining the optical density values at a specific wavelength. The dairy wastewater was not directly applied for the growth, but a standard medium was used to dilute it to a usable range. Procedures were followed to make the wastewater suitable for the cultivation of C. vulgaris. The wastewater before and after cultivation was examined to obtain the nutrient uptake rate of C. vulgaris for nitrogen. Two methods for lipid extraction were compared in order to find an efficient method. Extracted lipid content was compared with that from an outdoor cultivation and the lipids were characterized using GC-MS technique.

Download or read book Batch and Continuous Studies of Chlorella Vulgaris in Photo bioreactors written by Claudia Sacasa Castellanos and published by . This book was released on 2013 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microalgae are unicellular, photosynthetic microorganisms, they have minimal nutrient requirements and are being used as source materials for a variety of products such as protein rich nutritional supplements, pharmaceutical chemicals and pigments (used in food and cosmetics). They also grow extremely fast, in comparison to plants and many microalgae strains are exceedingly rich in oil which makes them great candidates for the production of biodiesel. The strain Chlorella vulgaris, has shown a great promise as a source of oil and as being able to help in the treatment of wastewater. Despite all the advantages, the high cost of production in bioreactors still remains a limitation and much research is required. The production of microalgae (Chlorella vulgaris) in different photobioreactor configurations (4L flask, tubular and stirred tank reactor) was investigated, using different media formulations and in both batch and continuous operation (for PBR and CSTR). The effect of dilution rate and mixing speed were both studied in the case of CSTR. The highest overall specific growth rate was found when growing C. vulgaris in continuous operation in a tubular photo-bioreactor,? = 0.7 d-1, which also reached the maximum biomass concentration of 0.79 g/L.

This book was released on 2019 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: In the current research work, green microalgae C. vulgaris was used for treating hydroponic and aquaponic wastewater collected from the Center for Applied Research on the Environment and Sustainability (CARES) at The American University in Cairo (New Cairo, Egypt) and for producing biomass. The present study was undertaken to evaluate the use of microalgae for bioremediating wastewater from greenhouse farm and for producing biomass under different conditions and to explore the economic implications of microalgal biofuels, focusing on the effect of different cultivation modes. Various experiments were carried out into four phases to assess the effect of different conditions into the nutrient removal and biomass production of C. vulgaris. It was observed that the cultivation of C. vulgaris under mixotrophic mode was found to be more beneficial in the bioremediation of hydroponic and aquaponic wastewater and in the production of biomass than heterotrophic and autotrophic modes of cultivation. The effect of different nitrogen to phosphorous molar ratios into nutrient removal and biomass production has also been assessed. Techno-economic assessment of microalgal biofuels has also been conducted, with a focus on the effect of different cultivation modes. The best results in terms of total nitrogen and total phosphorous treatment efficiency were reported for mixotrophic growth supplied with 2.5 g/l glucose and atmospheric CO2, showing reasonable removals of total nitrogen (TN) (98.5%), total phosphorus (TP) (99.99%) for hydroponic wastewater sample, and TN (98.5%), TP (99.9%) for aquaponic wastewater sample. The maximum biomass production and productivity were reported also for mixotrophic conditions in both hydroponic and aquaponic wastewater, showing a reasonable amount of biomass concentration (1.26 g/l) and biomass productivity (0.1108 g/l/d) for hydroponic wastewater, and biomass concentration and biomass productivity of 0.99 g/l, 0.089 g/l/d for aquaponic wastewater. Furthermore, the best results in terms of lipid content values were obtained under heterotrophic growth: 37 wt% on an Ash-free dry weight (AFDW) basis in aquaponic wastewater sample and a 33 wt% on an AFDW basis in hydroponic wastewater sample. On the other hand, the highest lipid production was obtained under mixotrophic growth (0.374 g/l) growth, followed by heterotrophic mode (0.341 g/l) in hydroponic wastewater sample. The best treatment efficiency were reported for N:P molar ratio of 8:1, displaying removals of TP (88%) and TN (85%) compared with that for N:P ratios of 16:1 and 24:1. Maximum values with respect to biomass production was reported for N:P molar ratio of 8:1 while biomass productivity was almost the same in all N:P molar ratios. Moreover, the best results regarding the net profit were obtained for both mixotrophic and heterotrophic cultivations of 26.4 MMUS$/y (2016 US$) and 26.1 MMUS$/y (2016 US$) respectively, while the net profit for autotrophic cultivation was 4.12 MMUS$/y (2016 US$). Sensitivity analysis shows that biodiesel and nutritious supplements from soluble protein have the greatest impact on the process economics with respect to mixotrophic cultivation while biodiesel and feeds from insoluble protein have the largest effect on the process economics in connection to both heterotrophic and autotrophic cultivations.

Download or read book Sustainable Development of Algal Biofuels in the United States written by National Research Council and published by National Academies Press. This book was released on 2013-01-18 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biofuels made from algae are gaining attention as a domestic source of renewable fuel. However, with current technologies, scaling up production of algal biofuels to meet even 5 percent of U.S. transportation fuel needs could create unsustainable demands for energy, water, and nutrient resources. Continued research and development could yield innovations to address these challenges, but determining if algal biofuel is a viable fuel alternative will involve comparing the environmental, economic and social impacts of algal biofuel production and use to those associated with petroleum-based fuels and other fuel sources. Sustainable Development of Algal Biofuels was produced at the request of the U.S. Department of Energy.
