“…Further, tested species of Portulaca accumulated significant amounts of Ni (Rooney et al 2007). Thus, it seems that plants have adapted to grow naturally on contaminated soils by employing diverse strategies to accumulate and detoxify high load of metals and metalloids (Grill et al 2006;Mishra et al 2006;Dwivedi et al 2008Dwivedi et al , 2010. Conclusively, Portulaca plants grow well at site contaminated with multiple metals and also showed rapid accumulation of metals and their efficient transport to shoots.…”

During the present study, two species of Portulaca, i.e., P. tuberosa and P. oleracea were collected from two field sites in Vadodara, Gujarat, India; one irrigated with industrial effluent and other with tube well water, and were analyzed for heavy metal accumulation in different plant parts viz., roots, stem, leaves, and flowers. Plants collected from effluent irrigated areas showed high accumulation of all the investigated heavy metals in all plant parts with the maximum being in roots and the least in flowers. Interestingly, both species of Portulaca demonstrated hyperaccumulation of multiple elements viz., Cu, Ni, Hg, and Pb. The total shoot concentrations (lg g -1 dw) of Cu, Ni, Hg, and Pb in P. tuberosa were 1538, 1191, 789, and 2744, respectively, while in P. oleracea, these were 1940, 1542, 534, and 2312, respectively. Besides this, selective hyperaccumulation of Se (2,327 lg g -1 dw) and Al (1,164 lg g -1 dw) was shown by P. tuberosa and P. oleracea, respectively. Total shoot concentrations (lg g -1 dw) of Mo were about 399 and 668 in P. tuberosa and P. oleracea, respectively. Overall, P. oleracea accumulated higher amounts of multiple metals from industrial effluent contaminated site, hence appears to be a suitable candidate for phytoremediation purposes of metal contaminated areas.

“…La, V, Cr, and U uptake by spirulina biomass during bioaccumulation process Cr(III) as an essential microelement can be involved in the biochemical processes of a cell. High rate of chromium accumulation can be explained by its incorporation in cell structures [1]. In case of lanthanum, the mechanism of its penetration into the cell is not well studied.…”

“…The presence of various metal ions in water bodies, arising from the discharge of industrial wastewater and other anthropogenic activities is one of the most important environmental issues due to high metal toxicity and accumulation in food chain [1]. Conventional techniques used for the removal of metal ions such as precipitation, oxidation, ion-exchange, electrochemical treatment have significant disadvantages including high cost, incomplete metal removal, high energy consumption, generation of large volume of sludge that require special disposal [2,3].…”

Spirulina platensis biomass is widely applied for different technological purposes. The process of lanthanum, chromium, uranium and vanadium accumulation and biosorption by Spirulina platensis biomass from single-and multi-component systems was studied. The influence of multi-component system on the spirulina biomass growth was less pronounced in comparison with the single-component ones. To trace the uptake of metals by spirulina biomass the neutron activation analysis was used. In the experiment on the accumulation the efficiency of studied metal uptake changes in the following order: La(V) > Cr(III) > U(VI) > V(V) (single-metal solutions) and Cr(III) > La(V) > V(V) > U(VI) (multi-metal system). The process of metals biosorption was studied during a two-hour experiment. The highest rate of metal adsorption for single-component systems was observed for lanthanum and chromium. While for the multi-component system the significant increase of vanadium and chromium content in biomass was observed. In biosorption experiments the rate of biosorption and the Kd value were calculated for each metal. Fourier transform infrared spectroscopy was used to identify functional groups responsible for metal binding. The results of the present work show that spirulina biomass can be implemented as a low-cost sorbent for metal removal from industrial wastewater.

“…In natural habitats these organisms are in different assemblages. Consortia based mitigation with increased diversity may lead to enhanced water purification (Zimmerman and Cardinale 2014;Chekroun and Baghour 2013;Chakraborty et al 2011;Dwivedi et al 2010;Cervantes et al 2001) through mitigating the increased chromium levels.…”

A set of experiments was conducted to provide significant insights of micro-algal consortia regarding chromium adsorption. Four monocultures; Scenedesmus dimorphus, Chlorella sp., Oscillatoria sp., and Lyngbya sp., and their synthetic consortia were evaluated initially for chromium bio-adsorption at four different regimes of hexavalent chromium i.e. 0.5, 1.0, 3.0 and 5.0 ppm. Based on findings, only 1.0 and 5.0 ppm were considered for future experiments. Consequently, three different types of monoculture and consortia cells namely; live cells, heatkilled cells, and pre-treated cells were prepared to enhance their adsorption potential. Maximal adsorption of 112% was obtained at the dose of 1.0 ppm with 0.1% SDS pretreated consortia cells over live consortia cells. In support, atomic absorption spectroscopy, laser induced breakdown spectroscopy, pulse amplitude modulated chlorophyll fluorescence, and scanning electron microscopy were performed to assess the structural and functional changes within consortia and their utilization in mitigation of elevated chromium levels.Keywords Micro-algal consortia Á Pulse amplitude modulated chlorophyll fluorescence (PAM) Á Scanning electron microscopy (SEM) Á Laser induced breakdown spectroscopy (LIBS) Á Atomic absorption spectroscopy (AAS)
