Characterization and fatty acid profiling in two fresh water microalgae for biodiesel production: Lipid enhancement methods and media optimization using response surface methodology

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

“…It contradicts with most of previous studies concerned with nitrogen deficiency. A comparison of nitrogen effect on biomass productivity, lipid content and lipid productivity with literature, including both autotrophic [15,26,28,29] and heterotrophic cultivation [17,27], is shown in Table 5, Most of the lipid productivities in these studies decreased after nitrogen starvation or limitation. Although Liang et al [30] reported similar biomass productivities between nitrogen sufficient (87 mg L À1 d À1 ) and nitrogen deficiency (79 mg L À1 d À1 ) conditions in a heterotrophic culture with 1% acetate, lipid productivity in nitrogen deficient culture only increased from 27 mg L À1 d À1 to 29 mg L À1 d À1 relative to the control.…”

Green renewable energy production from Myxosarcina sp.: media optimization and assessment of biodiesel fuel properties

“…and also reported that the presence of organic nitrogen in the effluent would influence the lipid productivity. 21 Biomass and lipid productivities of five different cyanobacteria in normal growth medium were found to be existing in the range of 3.7 to 52.7 mg/L/day and 0.8 to 14.2 mg/L/day respectively. 33 Hence from these experiments, it can be concluded that SIW supplementation enhanced biomass and lipid production in Myxosarcina sp.…”

“…(23%) under 2-3 % saline stress yielded higher lipid contents respectively. 21 On the other hand, microalgae under salinity stress could influence the biomass and lipid productivity at lower concentration NaCl (1 g) and that may inhibit the growth of microalgae where the concentration is increased. 28 The results are indicating that algae under saline stress may be an important tool for the production of biomass, lipid and that may also negatively affect the growth of algae at higher concentration.…”

“…8 Sugar industrial effluent comprises of high content of organic nitrogen and a minor amount of carbohydrates as reported in our earlier study. 21 37 Similarly, RSM was employed to enhance biomass and lipid production in Synechococcus sp. HS01 and reported that maximum lipid productivity of 56.5 mg/L/day was achieved (2.82 folds higher than control) in the media containing 0.09% NaCl, 1.12 g/L of NaNO 3 and 1% ostrich oil.…”

Enhancement of lipid production and fatty acid profiling in Chlamydomonas reinhardtii, CC1010 for biodiesel production

“…Partial organic carbon supplementation has increased the biomass and lipid productivity in Chlorella sorokiniana and Coelastrella sp. M60 (Wan et al, 2012;Karpagam et al, 2015b). Based on the earlier reports mentioned above, the effect of different concentrations of glucose supplementation in TAP media (0.05%, 0.1%, 0.15%, and 0.2%) on biomass concentration, lipid productivity and lipid content of C. reinhardtii, CC1010 were evaluated after 12 days of growth.…”
