“…For biodiesel product, the economic feasibility of microalgal mass culture have to be taken into consideration, the searching of microalgal species with high lipid content and high cell growth is a great importance (Lv et al, 2010). However, there are two categories of microalgae that used for lipid production such as: 1) high lipid content but low growth rate, for example Botryococcus braunii with lipid content of 50% but had low biomass productivity of 28 mg/L/day (Dayananda et al, 2007); 2) high growth rate but low lipid content, such as, Chlorella vulgaris (Griffiths and Harrison, 2009).…”

“…Enhancement lipid production in cell at various cultivation condition such as nitrogen deprivation and phosphate limitation (Rodolfi et al, 2009;Phadwal and Singh, 2003;Cheng et al, 2010), light intensity and temperature stressed (Tsovenis et al, 2003;Norman et al, 1985), iron supplementation and silicon deficiency Griffiths and Harrison, 2009) and different CO 2 concentration (Chiu et al, 2009;Ho et al, 2010) had been tested. Among them, nutrient deprivation has been the most studied aspect.…”

Microalgae is one of potential source for biodiesel due to high efficiency of solar energy conversion to chemical energy.Several microalgae also have high lipid content per dry weight of biomass. The aims of the present work to study the effects of temperature and nutrient depletion on the growth and lipid content of three selected microalgae (Dunaliella tertiolecta, Nannochloropsis sp and Scenedesmus sp) in view of their possible utilization as raw materials for biodiesel production. In addition, various lipid analysis methods were applied, such as gravimetric, Nile Red staining and FTIR spectroscopy. Algal growth and lipid content was strongly influenced by the variation of tested parameters; indeed, an increase or decrease temperature from ambient temperature and nutrient depletion practically increase in lipid content. Nile Red staining and FTIR spectroscopy are effective tool to analyze rapidly of lipid content from selected microalgae.

“…First, this particular strain of C. vulgaris has an amazing tolerance toward CO 2 (up to 50 %) compared to the results of Chiu et al (2008), who showed that the growth of Chlorella is limited by a CO 2 concentration exceeding 2 %. Furthermore, the lipid content reached its highest value at 30 % CO 2 , whereas Lv et al (2010) showed that lipid content decreased if the CO 2 concentration exceeded 1 %. Maeda et al (1995) showed that Chlorella can withstand 50 % CO 2 , but did not provide data on the lipid content.…”

“…One species of microalgae, Chlorella vulgaris, is ideal for biodiesel production because of its easier cultivation and higher photosynthetic efficiency as compared to terrestrial plants, and wide applicability (Griffiths and Harrison 2009;Keffer and Kleinheinz 2002). Although few strains, such as Botryococcus sp., are richer in lipid content (Huang et al 2013), C. vulgaris is still outstanding in lipid productivity (Hsieh and Wu 2009;Lv et al 2010). Moreover, C. vulgaris can be acclimated to high concentrations of CO 2 , rendering it suitable for commercial cultivation with flue gas as a source of CO 2 (Maeda et al 1995;Douskova et al 2009).…”

This study examined the cell growth rate, lipid contents, lipid productivity, chlorophyll a concentration, and carbon dioxide tolerance of Chlorella vulgaris under various cultivation conditions. The pH, concentration of carbon dioxide in media, and light intensity variables were manipulated to obtain high lipid productivity. The optimum conditions were at pH 7.0, 2,930 lux, and 30 % carbon dioxide. Biomass concentration reached 1,288, 1,130, and 1,083 mg L -1 at 15, 30, and 50 % CO 2 after 6 days, respectively, implying that this strain has appreciable tolerance to carbon dioxide. The highest concentration of chlorophyll a occurred at 2,930 lux and decreased with increasing light intensity gradually. The maximum specific growth rate was 3.25 day -1 based on the dry weight and 4.63 day -1 based on the cell number. The lipid content (45.68 %) and lipid productivity (86.03 mg day -1 L -1 ) obtained in this study are higher than reported values in literatures. Hence, C. vulgaris is a good candidate for subsequent research in biodiesel production under elevated carbon dioxide concentration by microalgae.

“…Increasing the lipid content under stress conditions could affect the biomass productivity. The productivity of biomass and the productivity of lipid content of C. vulgaris can both be enhanced if specific culture conditions are applied [8]. The lipid content in C. vulgaris can be increased by up to 56.6% of the dry biomass weight, by adding 1.2 × 10…”

Biofuels from the Fresh Water Microalgae Chlorella vulgaris (FWM-CV) for Diesel Engines

2014

View full text Add to dashboard Cite

This work aims to investigate biofuels for diesel engines produced on a lab-scale from the fresh water microalgae Chlorella vulgaris (FWM-CV). The impact of growing conditions on the properties of biodiesel produced from FWM-CV was evaluated. The properties of FWM-CV biodiesel were found to be within the ASTM standards for biodiesel. Due to the limited amount of biodiesel produced on the lab-scale, the biomass of dry cells of FWM-CV was used to yield emulsified water fuel. The preparation of emulsion fuel with and without FWM-CV cells was conducted using ultrasound to overcome the problems of large size microalgae colonies and to form homogenized emulsions. The emulsified water fuels, prepared using ultrasound, were found to be stable and the size of FWM-CV colonies were effectively reduced to pass through the engine nozzle safely. Engine tests at 3670 rpm were conducted using three fuels: cottonseed biodiesel CS-B100, emulsified cottonseed biodiesel water fuel, water and emulsifier (CS-E20) and emulsified water containing FWM-CV cells CS-ME20. The results showed that the brake specific fuel consumption (BSFC) was increased by about 41% when the engine was fueled with emulsified water fuels compared to CS-B100. The engine power, exhaust gas OPEN ACCESSEnergies 2014, 7 1830 temperature, NO x and CO 2 were significantly lower than that produced by CS-B100. The CS-ME20 produced higher power than CS-E20 due to the heating value improvement as a result of adding FWM-CV cells to the fuel.
