Download or read book Biofuels from Algae written by Man Kee Lam and published by Elsevier Inc. Chapters. This book was released on 2013-08-08 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: Algae are currently being considered as a versatile feedstock for biofuel production because of their fast growth rate and high biomass productivity. Algae could simultaneously act as a carbon sink and water purifier if their cultivation were coupled with flue gas and wastewater treatment, respectively. Hence, an understanding of the overall supply chains for algal biofuel production is exceptionally important to determine whether it is worthwhile to scale up and commercialize algal cultivation for biofuel production. In this chapter, various aspects and constraints associated with the commercialization of algal biofuels are deliberated in detail, especially from the perspective of life-cycle energy balance. In addition, discussions on the economic assessments of algal biofuels are included in this chapter to provide an overview of the current state of algal biofuels in the fuel market. Potential algal biofuel conversion technologies, such as transesterification, starch hydrolysis and fermentation, pyrolysis, and hydrothermal liquefaction are also presented.
Download or read book Microalgae Biotechnology for Development of Biofuel and Wastewater Treatment written by Md. Asraful Alam and published by Springer. This book was released on 2019-04-30 with total page 646 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses microalgae, which represent a very promising biomass resource for wastewater treatment and producing biofuels. Accordingly, microalgae are also an expanding sector in biofuels and wastewater treatment, as can be seen in several high-profile start-ups from around the globe, including Solix Biofuels, Craig Venter’s Synthetic Genomics, PetroSun, Chevron Corporation, ENN Group etc. In addition, a number of recent studies and patent applications have confirmed the value of modern microalgae for biofuels production and wastewater treatment systems. However, substantial inconsistencies have been observed in terms of system boundaries, scope, the cultivation of microalgae and oil extraction systems, production costs and economic viability, cost-lowering components, etc. Moreover, the downstream technologies and core principles involved in liquid fuel extraction from microalgae cells are still in their early stages, and not always adequate for industrial production. Accordingly, multilateral co-operation between universities, research institutes, governments, stakeholders and researchers is called for in order to make microalgae biofuels economical. Responding to this challenge, the book begins with a general introduction to microalgae and the algae industry, and subsequently discusses all major aspects of microalgal biotechnology, from strain isolation and robust strain development, to biofuel development, refinement and wastewater treatment.
Download or read book Cultivation and GC MS Analysis of Chlorella Vulgaris Grown in a Photobioreactor on Dairy Wastewater written by Jayamini Madumali Mudugamuwa Hewage and published by . 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 Sustainable Downstream Processing of Microalgae for Industrial Application written by Kalyan Gayen and published by CRC Press. This book was released on 2019-09-05 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microalgae can be future resource for industrial biotechnology In current energy crisis era, microalgae are under tremendous research focus for the production of biodiesel due to their high photosynthetic efficiency, growth rate and high lipid content compared to territorial plants. However, the large-scale production of algal biomass and downstream processing of harvested algae towards bio-fuels are facing several challenges from economic viability perspective. Apart from bio-fuels, the microalgae synthesize number of bio-molecules such as pigments (e.g., chlorophyll, carotenoid), protein (e.g., lectin, phycobiliprotein), and carbohydrates (e.g., agar, carrageenan, alginate, fucodian) which are available in the various forms of microalgal products. Therefore, developing a strategy for large-scale production and use of algal biomass for the co-production of these value-added macromolecules is thus imperative for the improvement of the economics of algal biorefinery. In the above context, this book covers three major areas (i) commercial-scale production of bio-molecules from microalgae, (ii) sustainable approach for industrial-scale operation, and (iii) optimization of downstream processes. Each of these sections is composed of several chapters written by the renowned academicians/industry experts. Furthermore, in this book, a significant weightage is given to the industry experts (around 50%) to enrich the industrial perspectives. We hope that amalgamate of fundamental knowledge from academicians and applied research information from industry experts will be useful for forthcoming implementation of a sustainable integrated microalgal biorefinery. This book highlights following. Explores biomolecules from microalgae and their applications Discusses microalgae cultivations and harvesting Examines downstream processing of biomolecules Explores sustainable integrated approaches for industrial scale operations Examines purification techniques specific for microalgal proteins, Omega 3 fatty Acids, carbohydrates, and pigments

Download or read book Biofuels from Algae written by S. Venkata Mohan and published by Elsevier Inc. Chapters. This book was released on 2013-08-08 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biologically produced fuels are considered potential and viable alternatives to meet the world’s fuel requirements. In this context, algal-based oil is of significant importance due to its renewable and carbon-neutral nature. Biosynthesis of triglycerides by utilizing CO2 (by biofixation) or wastewater under stress conditions via photoautotrophic, heterotrophic (photo/dark), or mixotrophic mechanisms enumerates the potential of microalgae for generation of renewable biodiesel. In addition to the algal cultivation, the conversion of the accumulated lipids to biodiesel is gaining considerable interest. Though there exist some constraints, the process of harnessing biofuel from microalgae is both economically viable and environmentally sustainable compared to the other oil-producing terrestrial crops. This chapter explores biofuel production using microalgae. Concerted efforts are made in this chapter to discuss the biochemistry pertaining to algal lipid synthesis, nutritional modes of algae, cultivation systems used for algal oil production, and the cascade of steps involved, from biomass cultivation to transesterification of the fuel. The ability of microalgae to capture CO2 and its survivability in wastewater is also elaborated in the context of lipid synthesis.
