Lipid accumulation and growth of Chlorella zofingiensis in flat plate photobioreactors outdoors

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

“…High inoculum density was unfavorable for accumulating lipid in photoautotrophic cultivation because of self-shading. In previous study of N. oculata (Su et al, 2010) and Chlorella zofingiensis (Feng et al, 2011), both observed the negative correlation between inoculums size and lipid accumulation which was similar to the results obtained in present study. All the results may reflect the reduction in effective irradiance in dense microalgal culture, in short, the light received by single cells was declined in dense culture.…”

“…This was mainly due to the lower light penetration in dense culture which caused the cells receiving little light to maintain its quick metabolism and growth. Many reports had noted that a certain extent increasement of inoculum density may increase biomass productivity (Su et al, 2010;Feng et al, 2011). Similarly, as concluded in Table 2, the maximum biomass productivity was found at OD 680 -0.4 (223.17 mg L À1 d…”

“…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. The information about lipid accumulation in microalgae under different initial incolumn density is rare, which is only mentioned in Nannochloropsis oculata (Su et al, 2010) and Chlorella zofingiensis (Feng et al, 2011), but how it comes to Ankistrodesmus sp. ?…”

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).…”

Cloning and expression analysis of accD gene in Chlorella protothecoides FACHB-2

“…Many species in the genus Chlorella have received considerable attention for being able to accumulate neutral triacylglycerols, an ideal feedstock for biodiesel production (Feng et al, 2011;Hsieh et al, 2012;Mujtaba et al, 2012;Wang et al, 2012;Xu et al, 2006;Xiong et al, 2010;Xie et al, 2012). Compared with large amounts of work focusing on improving the lipid content from technical aspects, investigation on the regulation mechanism of lipid synthesis has somewhat fallen behind.…”
