“…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). …”

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.

“…Previous studies used the Chu-13 medium (Sawayama et al 1994, Dayananda et al 2005, Ranga Rao et al 2007, Ashokkumar and Rengasamy 2012 or the BG-11 medium (Dayananda et al 2007, Ge et al 2011) for culturing of Botryococcus braunii. Thus, the present study tested the effect of the growth medium on the three Korean strains of B. braunii by incubation in BG-11, Chu-13, and DY-III media.…”

“…Numerous studies have attempted to optimize the conditions for growth and lipid production in B. braunii (Casadevall et al 1985, Li and Qin 2005, Dayananda et al 2007, Yeesang and Cheirsilp 2011. Other studies examined the effect of variables such as growth medium, temperature, pH, light intensity, and CO 2 concentration on lipid production and growth of B. braunii (Lupi et al 1991, Kalacheva et al 2002, Ranga Rao et al 2007).…”

Three strains of the green microalga Botryococcus braunii (JJS, KCM, and KJD) were isolated from different water bodies in Korea and grown as batch cultures in the laboratory. The effects of different growth media and temperatures on the growth rate were investigated, as well as the effect of temperature on the total lipid content and lipid profile. All three strains had the highest growth rates in BG-11 medium and at 25°C. Maximal lipid production (g L -1) was at 30°C in the JJS strain and at 25°C in the KCM and KJD strains. However, all the three strains produced the greatest percent dry weight of total lipids at 15°C and had the lowest percent dry weight of total lipids at 25°C. In general, oleic acid, linolenic acid, and behenic acid were the most common fatty acids in all three strains. However, the three strains varied considerably in their fatty acid profiles at different culture temperatures.

“…with lipid contents of 50 to 77%, and Neochloris oleoabundans with lipid contents of 35 to 65%. However, those species grow slowly and have low rates of oil production [5]. In contrast, other species (for instance, Chlamydomonas reinhardtii, Chlorella pyrenoidosa and Navicula pelliculosa) grow rapidly but with low lipid content (<15%) [6,7].…”

Background: The lipid content of microalgae is regarded as an important indicator for biodiesel. Many attempts have been made to increase the lipid content of microalgae through biochemical and genetic engineering. Significant lipid accumulation in microalgae has been achieved using biochemical engineering, such as nitrogen starvation, but the cell growth was severely limited. However, enrichment of lipid content in microalgae by genetic engineering is anticipated. In this study, GmDof4 from soybean (Glycine max), a transcription factor affecting the lipid content in Arabidopsis, was transferred into Chlorella ellipsoidea. We then investigated the molecular mechanism underlying the enhancement of the lipid content of transformed C. ellipsoidea.
