The wide application of microalgae in the field of wastewater treatment and bioenergy source has improved research studies in the past years. Microalgae represent a good source of biomass and bio-products which are used in different medical and industrial activities, among them the production of high-valued products and biofuels. The present review focused on greywater treatment through the application of phycoremediation technique with microalgae and presented recent advances in technologies used for harvesting the microalgae biomass. The advantages and disadvantages of each method are discussed. The microbiological aspects of production, harvesting and utilization of microalgae biomass are viewed. 相似文献

Contamination indices and heavy metal concentrations in urban soil of Ibadan metropolis, southwestern Nigeria 总被引:1,自引:0,他引:1
An assessment was conducted on soils of Ibadan metropolis using geochemical approach in order to establish the concentration
of heavy metals and develop geoaccumulation index maps. Petrographic studies and X-ray diffractograms showed that soils of
Ibadan were derived from the weathering of the bedrocks. The concentrations of Cu, Pb, and Zn were found to be greater in
soils more than the background. Positive correlation occurred between Cu, Pb, and Zn indicated a common anthropogenic source
in the soil while Mn, Cr, and Ni were found to be naturally enriched. The geoaccumulation index maps revealed significant
enrichment factor (Ef > 20) and index of geoaccumulation (Igeo) beyond class four (heavily contaminated) for Cu, Pb, and Zn
in densely populated and industrial areas, whereas Cd is enriched in sparsely populated areas, agricultural areas and a few
spots in densely populated areas. 相似文献
