Light intensity affects tolerance of pyrene in Chlorella vulgaris and Scenedesmus acutus
نویسندگان
چکیده
The impact of light intensity on the toxicity pyrene, a 4-ring polycyclic aromatic hydrocarbon (PAH), was studied in Chlorella vulgaris and Scenedesmus acutus. Both species were cultured under low light, LL [50-60 µmol(photon) m-2 s-1], high HL [100-110 s-1] conditions to study effects pyrene (PYR) growth parameters, content biomolecules, chlorophyll content, photosynthetic efficiency. In presence PYR, S. acutus could grow well intensity. On other hand, C. showed drastic decrease photosynthesis during due PYR toxicity. Regulation nonphotochemical photochemical quenching responsible for survival conditions. Thus, seems be more promising candidate degradation varying

Demography of zooplankton (Anuraeopsis fissa, Brachionus rubens and Moina macrocopa) fed Chlorella vulgaris and Scenedesmus acutus cultured on different media.
Generally zooplankton growth is often limited by the quality of their algal diet. A cheaper common practice in aquaculture, is to culture algae with fertilizers; however, the demography of zooplankton when fed these algae has not yet been evaluated. We studied the population growth and life table demography of the rotifers Anuraeopsis fissa and Brachionus rubens, and the cladoceran Moina macroc...
متن کاملDifferential Response of Green Algal Species Pseudokirchneriella subcapitata, Scenedesmus quadricauda, Scenedesmus obliquus, Chlorella vulgaris and Chlorella pyrenoidosa to Six Pesticides
This work examines the effects of six pesticides on five green algae: Pseudokirchneriella subcapitata, Scenedesmus quadricauda, Scenedesmus obliquus, Chlorella vulgaris and Chlorella pyrenoidosa. The results indicate that the decreasing order of the average toxicity to five algae was: fluazinam > propineb > maneb > mancozeb > zineb > bromoxynil octanoate. however, according to sensitivity magni...
متن کاملPlastocyanin microheterogeneity in Scenedesmus acutus MT8.
Two total plastocyanin (PC) fractions - loosely bound (lPC) and strongly bound (sPC) were extracted (84% and 16%, respectively) from the homogenate of Scenedesmus acutus MT8. Two-fold isolation-purification procedure including DE-52 chromatography separated IPC into a smaller oxidized [IPC (II)] and a larger reduced [IPC(I)] fractions, in contrast to sPC, where sPC(ll) greatly dominated over sP...

Nano ZnO is currently used in the rubber, electronics, electrical appliances, enamel, cosmeticsand medical industry. Whereas most studies have used the ecological toxicity of nanoparticles, the toxic effects of nanoparticles in diet is not extensively explored. Because the algaeare at the base of the food chain, any change in their density, biomass and population, wouldaffect the food chain in ...
متن کاملAlgal growth response and survival in a range of light and temperature conditions: implications for non-steady-state conditions in waste stabilisation ponds.
Growth and physiological experiments were carried out using Scenedesmus subspicatus and Chlorella vulgaris as representative species typically found in waste stabilisation ponds. These experiments were designed to test the ability of the organisms to survive and grow under a range of different temperatures and light intensities that might occur in mid to high latitude regions. Growth was assess...
