Lipid analysis in Haematococcus pluvialis to assess its potential use as a biodiesel feedstock

Effects of light intensity and quality on phycobiliprotein accumulation in the cyanobacterium Nostoc sphaeroides Kützing

“…Algae have been used as food for thousands of years, but their derived biological activity products have been recognized for commercial value for only a few decades (Borowitzka 1992;Chen et al 2013;Damiani et al 2010;Feng et al 2011). Recent industrial and scientific advancements have promoted the development of an increasing number of new algae used for food, medicine, cosmetics and chemical industries (Spolaore et al 2006).…”

Optimizing light regimes on growth and lipid accumulation in Ankistrodesmus fusiformis H1 for biodiesel production

“…At present, how to maximize lipid yield, reduce the cost and increase manipulation flexibility dealing with the various technology bottlenecks of the lipid production process in microalgae cultivation are the important tasks (Delrue et al, 2013;Bellou et al, 2014;He et al, 2015a). Nutrient (especially nitrogen) and light regimes (i.e., incolumn density, photoperiod and light intensity) are the major environmental determinants of microalgae growth, metabolism and morphology, including the accumulation of lipids in the form of triacylglycerols (TAG) (Eberhard et al, 2008;Damiani et al, 2010;Wahidin et al, 2013;He et al, 2015a,b). As vigorous growth and lipid accumulation are usually mutually exclusive in naturally occurring microalgae, so optimizing the cultivation strategy is the cornerstone to achieve biodiesel production.…”

“…Summarized the productivities in Table 2 intensity affects the relative size of the lipid pools and the fixation of carbon increased with light, thus, lipid storage can provide a larger sink for the available energy, especially when light was in excess to the requirement for growth (He et al, 2015a,b). In many literatures, it had been proved that higher light can synchronously accumulate both biomass and lipid to achieve large amounts of lipid products eventually (Damiani et al, 2010;Ho et al, 2014;Gwak et al, 2014;He et al, 2015a,b;Xiao et al, 2015). However, the necessity of light varied in microalgae from one to another, even in same species.…”

Exploitation of Microalgae Species for Nutraceutical Purposes: Cultivation Aspects

“…Most recently, a two-stage mixotrophic cultivation system for astaxanthin production in H. pluvialis was suggested [30]. Some studies considered H. pluvialis biomass for biodiesel production because of their suitable fatty acids profile [29,31]. It was proposed that H. pluvialis biomass after extraction of astaxanthin can be used as feedstock for bioethanol or biomethane production [32][33][34].…”
