Phosphorus plays an important role in enhancing biodiesel productivity of Chlorella vulgaris under nitrogen deficiency

Bicarbonate supplementation enhanced biofuel production potential as well as nutritional stress mitigation in the microalgae Scenedesmus sp. CCNM 1077

“…221.13 ± 6.07 mg/L under combined nutrient starvation. Similar to our study, Chu et al (2013) also found reduction in total DCW production by microalgae Chlorella vulgaris in nitrate (95.4 mg/L/day) and phosphate (38.3 mg/L/day) starved cultures compared to control culture (100.4 mg/L/day). In the present study, DCW production was not much affected under phosphate starvation and only 19% reduction in DCW (320.87 ± 11.68 mg/L) was observed.…”

“…Nutrients limitations like nitrate, phosphate or combined nitrate and phosphate limitations have resulted in higher accumulation of lipid in various microalgae (Chu et al, 2013(Chu et al, , 2014Li et al, 2014). However, only few researchers have studied the effects of bicarbonate addition under nitrate limited growth conditions (White et al, 2013;Guihéneuf and Stengel, 2013) and there are no reports on effects of bicarbonate addition under phosphate or combined nitrate phosphate stress conditions in microalgae.…”

Enhancement of FAME productivity of Scenedesmus obliquus by combining nitrogen deficiency with sufficient phosphorus supply in heterotrophic cultivation

“…The samples were analyzed using a gas chromatograph (Agilent 6890, CA). All the parameters were set according to Chu et al [24]. FAME productivity was calculated based on Eq.…”

Screening high oleaginous Chlorella strains from different climate zones

“…Table 2 Contents (% of dry cell weight) and fatty acid compositions (% of total fatty acids) of total lipids and triacylglycerols of five Chlorella species cultured at 25°C. 12.99 ± 1.06 Chen et al, 2011a;Chu et al, 2013;Li et al, 2012;Li et al, 2013;Liu et al, 2011;Mata et al, 2010;Miao and Wu, 2006). However, only C. sorokiniana, C. vulgaris and C. pyrenoidosa are ''true'' Chlorella species according to their biochemical and phylogenetic characteristics (Huss et al, 1999;Krienitzi et al, 2004).…”
