Research ArticleOpen accessEvery word in the titleComparative Study of Properties of Biopolymers from Corn Starch with Addition of Microalgae Spirulina platensisJúllia Koury Abreu, Loraynne Coelho Pereira, José Izaquiel Santos da SilvaThe discovery of the environmental impacts caused by petroleum-based polymers has led to the use of natural polymers gaining more and more space. Naturally occurring polymers, also known as biopolymers, are chemical compounds produced by living things or raw materials from renewable energy sources. Their main advantage is decomposition, while polymers from fossil and non-renewable energies can take hundreds of … …American Journal of Engineering and Applied Sciences, Vol. 16, Issue 1 · 16 Mar 2023 · 6,026 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Salinity, pH, Light Intensity on Growth and Lipid Production of Microalgae for Bioenergy ApplicationMonika Prakash Rai, Trishnamoni Gautom, Nikunj SharmaThe crisis of energy producing molecules (fuels) is expected to increase in future, which is currently produced from crude mineral oil. Biodiesel is most reliable, non-toxic, biocompatible liquid fuel that can replace the existing unsustainable sources of energy. Among all the known sources, microalgae display high potential for the production of biodiesel owing to their numerous benefits like higher biomass … …OnLine Journal of Biological Sciences, Vol. 15, Issue 4 · 5 Nov 2015 · 16,789 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Light Exposure and Nitrogen Source on the Production of Oil from Freshwater and Marine Water MicroalgaeMariam Al Hattab, Abdel GhalyThe biomass yield and oil content of Chlorella saccharophila (freshwater) and Tetraselmis suecica (marine) microalgae were investigated using various nitrogen source (ammonium nitrate, ammonium phosphate, ammonium sulfate and combination of nutrients) at various light durations (9, 16 and 24 h). NaHCO3 was used as the carbon source. The nitrogen concentration, temperature and pH were maintained at 70 mg/L, 22°C and … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 4 · 8 Dec 2014 · 7,265 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleINDUCES OF ANTIOXIDANT COMPOUNDS AND SALT TOLERANCE IN WHEAT PLANT, IRRIGATED WITH SEAWATER AS RESPONSE TO APPLICATION OF MICROALGAE SPRAYHanaa H. Abd El Baky, M. M. Hussein, Gamal S. El-BarotyWheat plants (Triticum aestivum L., cv. Giza 168) irrigated with either 10 or 20% of Seawater (SW) were treated with aqueous extracts of green microalgae Scenedesmus obliquus and blue green algae Spirulina platensis (AESO and AESP 20 g (dry weight)/L) in order to increase wheat salt tolerance. Treated plants showed higher ability to tolerate salt stress (10 or 20% SW) … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 2 · 7 Jan 2014 · 7,591 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMixed-Polarity Azeotropic Solvents for Efficient Extraction of Lipids from Nannochloropsis MicroalgaeRobert D. Long, Elseddik AbdelkaderProblem statement: The extraction of lipids from microalgae for biofuel production is a significant problem due to the intractability of their cell wall. The aim of this study of lipid extraction from Nannochloropsis microalgae was to examine the relative efficiencies of some commonly used solvent systems and test the use of co-boiling solvents in Soxhlet extraction as an improved method. … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 2 · 12 Aug 2011 · 9,387 accessesView PDFCite
