“…The performance of the blend was determined by examining the emission of a 25.8 kW agricultural tractor engine. The physicochemical properties of the blends prepared from microalgae S. platensis biodiesel and petro-diesel (B2, B5, B10 and B20) were by Mostafa and El-Gendy (2013). The characteristics of the B5-B20 blends corroborated with the petro-diesel marketed in Egypt.…”

Gradual increase in concentration of carbon dioxide (CO 2 ) in the atmosphere due to the various anthropogenic interventions leading to significant alteration in the global carbon cycle has been a subject of worldwide attention and matter of potential research over the last few decades. In these alarming scenario microalgae seems to be an attractive medium for capturing the excess CO 2 present in the atmosphere generated from different sources such as power plants, automobiles, volcanic eruption, decomposition of organic matters and forest fires. This captured CO 2 through microalgae could be used as potential carbon source to produce lipids for the generation of biofuel for replacing petroleum-derived transport fuel without affecting the supply of food and crops. This comprehensive review strives to provide a systematic account of recent developments in the field of biological carbon capture through microalgae for its utilization towards the generation of biodiesel highlighting the significance of certain key parameters such as selection of efficient strain, microalgal metabolism, cultivation systems (open and closed) and biomass production along with the national and international biodiesel specifications and properties. The potential use of photobioreactors for biodiesel production under the influence of various factors viz., light intensity, pH, time, temperature, CO 2 concentration and flow rate has been discussed. The review also provides an economic overview and future outlook on biodiesel production from microalgae.

“…According to a previous study, this value for microalgal biodiesel ranges from 39 to 54 [64]. A CN value of 70 was previously reported for biodiesel from the microalga Spirulina platensis [65]. High CN in yeast biodiesel can be attributed to increase in saturated FAMEs content and its chain length [65].…”

“…A CN value of 70 was previously reported for biodiesel from the microalga Spirulina platensis [65]. High CN in yeast biodiesel can be attributed to increase in saturated FAMEs content and its chain length [65]. Higher CN results in higher combustion efficiency, improved engine performance and cleaner emissions and can be recommended for use in the high-speed engine (speeds above 800 rpm) [65].…”

Higher CN results in higher combustion efficiency, improved engine performance and cleaner emissions and can be recommended for use in the high-speed engine (speeds above 800 rpm) [65]. Conversely, fuels with low CN will cause difficulty in engine starting, generate higher noise and exhaust smoke [65].…”

The depletion of exhaustible underground petroleum resources has put the present civilization at stake, thereby warranting intense research on non-exhaustible fuel. With this energy crisis hitting the block, microorganisms such as yeasts are gaining wider importance as potential biofuel candidates. An indigenous yeast strain Saccharomyces cerevisiae isolated from laboratory-scale brewing was investigated for biodiesel production. Biodiesel was produced by in situ transesterification approach using 1,1,3,3-tetramethylguanidine as the catalyst. The fuel properties such as viscosity, density, calorific value and cetane number (CN) were determined to assess the fuel quality of S. cerevisiae biodiesel. Additionally, the investigation also focuses on theoretical studies considering the yeast de-oiled cake (low-value biomass refuse). Fatty acid methyl ester analysis revealed that biodiesel was primarily composed of tricosylic acid (C23:0, 28.71%), palmitoleic acid (C16:1, 28.96%) and oleic acid (C18:1, 18.13%). Eicosapentaenoic acid (C20:5, 2.01%), one of the most commonly known polyunsaturated fatty acid, was present in the yeast strain. The CN of yeast biodiesel was 71.58, which was much higher than petro-diesel. The theoretical findings suggest the competitiveness of yeast biomass conversion technologies with petroleum refining process economics. The overall study warrants the feasibility of co-production of biodiesel from S. cerevisiae and cracked biofuel products (from S. cerevisiae de-oiled cake) under the aegis of biorefining applications.

“…Until now, the nonrenewable fossil fuel has been opted as the main source of energy in many parts of the world with the limitation in availability [2]. The increasing demand which does not correspond with the depleting fossil fuel resources has promoted many attempts to develop renewable energy sources [3]. In the recent years, the search for alternative fuel is growing quite rapidly.…”

Biodiesel Production from Wet Spirulina sp. by One-Step Extraction-Transesterification

et al. 2018

Abstract. Microalgae has gained immense interests as the raw material for biofuel production. The lipid content in microalgae can be converted into biodiesel through conventional method which involves separated process of extraction and transesterification. In this study, the production of biodiesel from Spirulina sp. was performed through one-step extraction-transesterification using KOH as base catalyst to simplify the production of biodiesel. The mixture of methanol-hexane was employed as both solvent and reactant in the process. The resulting biodiesel was found to be mainly composed of methyl oleate and methyl palmitate. On the other hand, increasing the reaction temperature and reducing the quantity of methanol in solvent mixture would also increase the yield of biodiesel. The optimum methanol-hexane volumetric ratio and temperature which gave the highest biodiesel yield were 3:7 and 50 o C, respectively.
