“…Heavy metals can change the lipid and fatty acid composition of algae (Rocchetta et al, 2006;Vavilin et al, 1998). The mechanisms involve mostly oxidative stress and the production of reactive oxygen/ nitrogen species that lead to oxidation of lipids (Pinto et al, 2003b).…”

“…The lipid content can be altered by various factors (Hsieh and Wu, 2009;Rodolfi et al, 2009;Takagi and Yoshida, 2006;Liu et al, 2008) including heavy metals (Dragone et al, 2011;Rocchetta et al, 2006;Sunda et al, 2005;Vavilin et al, 1998). Copper has been used as pesticide to control algal blooms (Rai et al, 1981;Horne and Goldman, 1974) which disrupts photosynthesis, respiration, ATP production, pigment synthesis and inhibits cell division (Cid et al, 1996;Stauber and Florence, 1987).…”

Higher photosynthetic efficiency and biomass production with rapid growth makes microalgae as potential candidates over other energy crops in many applications. Heavy metals influence the production of secondary metabolites and lipd content of microalgae in particular. A study was conducted using six Chlorella species under heavy metal exposure to evaluate the copper stress on biomass, cellular and lipid contents. Preliminary growth studies indicated the growth tolerance levels of Chlorella in the presence of copper at 4.0 mg L −1 concentration. The total chlorophyll, protein and lipid content of the isolates were 1.7-3.45%, 0.43-0.70 mg g −1 and 0.02-0.11 mg g −1 respectively. Gas Chromatography-Mass Spectroscopy analysis revealed that the percent composition of fatty acids varied among the species studied and the major group of fatty acids were C16:0, C18:1 and C18:2. Highest percent of fatty acids were found in C. vulgaris, C. protothecoides and C. pyrenoidosa. Copper have an impact on Chlorella species where biomass content was directly proportional to the lipid productivity. The results reflects the fact that copper stress on Chlorella species as the evidence of lipid production in both qualitative and quantitative manner. In conclusion, Chlorella species can be used for the sustainable producion of renewable energy through copper stress and removal of copper from aqueous solutions.

“…Zinc was observed to cause an increase in glutathione pools, in particular of glutathione disulfide (GSSG), causing a decrease of its redox ratio, i.e., to cause oxidative stress in Enteromorpha species already from 0.1 to 0.2 mg l -1 (Malea et al 2006). On the other hand, lipid peroxidation levels in Chlorella pyreonidosa increased only from 30 lM zinc (*2 mg l -1 ; Vavilin et al 1998), or from 6.5 mg l -1 in P. viridis (Li et al 2006). …”

Effects of zinc on growth, cell morphology, oxidative stress responses and zinc removal activity of two common phytoplankton species, Monoraphidium pusillum (Printz) Komárková-Legnerová and Monoraphidium griffithii (Berkeley) Komárková-Legnerová were investigated at a concentration range of 0.2-160 mg l -1 zinc. Cell densities and chlorophyll content decreased compared with controls in cultures of both species, effective concentrations causing 50 % growth inhibition within 72 h on the basis of cell numbers were 33.69 and 25.63 mg l -1 zinc for M. pusillum and M. griffithii, respectively. Changes in cell morphology and elevated lipid peroxidation levels appeared in zinc-treated cultures of both species, but only at higher ([10 mg l -1 ) zinc concentrations. The most effective zinc removal appeared at 20 and 10 mg l -1 zinc concentration for M. pusillum and M. griffithii, respectively. Removed zinc is mainly bound on the cell surface in the case of both species. This study provides new data for the zinc tolerance and zinc removal ability of the green algae M. pusillum and M. griffithii and shows that green algal species common in surface waters could have zinc tolerance and zinc-binding abilities, which makes them feasible in treatment of waters contaminated with 10-20 mg l -1 zinc.
