Screening of marine microalgae for biodiesel feedstock

Isolation and Characterization of Native Microalgae from the Peruvian Amazon with Potential for Biodiesel Production

“…strain AMA002) to 31.6 ± 0.4 mg·L −1 ·d −1 (Acutodesmus obliquus strain AMA004). Similar biomass productivities were reported for other marine microalgae species [54]. However, other investigations show major biomass productivities (ranging from 30 to 120 mg·L −1 ·d −1 ) in the same and other microalgae genera [45,55,56].…”

“…In accordance with these reports, Li et al [69] showed that nitrogen deficiency induced, in the green microalgae Micractinium pusillum, a downregulation in the expression of genes involved in cell growth and cell cycle regulation. Additionally, differences in growth profile and specific growth rates are dependent on several factors, such as microalgae genotypes, the culture medium composition, pH, nutrients concentration, the cell culture phase (i.e., log phase, stationary phase) and environmental factors [45,49,54,57,[70][71][72]. …”

Selection of microalgae for biodiesel production in a scalable outdoor photobioreactor in north China

“…The peaks for Palmitic acid (C16:0) and oleic acid (C18:1) in Desmodesmus and Scenedesmus were consistent with the observations by Nascimento et al (2013) and Song et al (2014). In addition, highly unsaturated FA, C20-C24 with 3-6 double bonds, appear to be more commonly occurring in the FA of algal oils but barely detected in the eight microalgae (Doan et al, 2011;). The consensus view is that the most favorable biodiesel would have rather low levels of polyunsaturated (PUFA) and low levels of saturated FA (SFA) to decrease oxidative stability and low temperature property (Knothe, 2009).…”

“…For example, Nannochloropsis, as one of the most promising sources of oil feedstock for biodiesel production, has high biomass production capacity and relatively high lipid content (Rodolfi et al, 2009); however, being rich in long chain polyunsaturated fatty acids (PUFA) (Doan et al, 2011;Griffiths et al, 2012), which is not desirable for biodiesel properties (e.g., ignition quality and oxidative http://dx.doi.org/10.1016/j.biortech.2014.10.008 0960-8524/Ó 2014 Elsevier Ltd.

Screening and Characterization of Oleaginous Microalgal Species from Northern Xinjiang

“…Third-generation biodiesel feedstocks derived from microalgae have emerged as one of the most promising alternative sources [2]. With the deep understanding of microalgae, the problem of microalgae germplasm resources is becoming increasingly prominent; algal species almost become the main factors that restrict the development of the bioenergy industry [7,23]. Therefore, screening for indigenous oleaginous microalgae with a rapid growth rate and high lipid productivity (LP) is the key to support this technique [24].…”
