Bioremediation of cadmium by growing Rhodobacter sphaeroides: Kinetic characteristic and mechanism studies

Isolation of purple nonsulfur bacteria for the removal of heavy metals and sodium from contaminated shrimp ponds

“…found that the removal efficiency is higher at higher initial concentrations (Al-Momani et al 2007;Bai et al 2008;Monteiro et al 2009). This could be one reason why the removal of Cd was so low as its initial concentration was very low when compared with other HMs (Table 3).…”

Application of alkaline phosphatase for heavy metals precipitation using ascorbic acid 2-phosphate as an effective natural substrate

“…To circumvent the problem, Bai et al tried to remove cadmium by using Rhodobacter sphaeroides, a phototrophic bacterium that is omnipresent in soil, wastewater, activated sludge, fresh, and marine water. However, the precipitation was found to be biomass-dependent and longer period of incubation, i.e., 54 h, as opposed to 42 h resulted in lesser recovery of Cd (in other words, only 14 % instead of 97 % recovery) from 40 ppm cadmium sulfate solution (Bai et al 2008). To develop a potential bioremediation technique, BAP and CIAP along with ascorbic acid 2-phosphate were used in this study to remove cadmium from industrial wastewater.…”

“…precipitation from single-ion solutions by BAP and CIAP Cadmium is a highly toxic and carcinogenic heavy metal, which is usually present in the wastewater of industries associated with mining, electroplating, electronic, and metallurgical activities (Nagata et al 2008;Bai et al 2008). According to Central Pollution Control Board (CPCB), India, the permissible limit of cadmium in industrial effluent is 2 ppm (CPCB 1986).…”

Cobalt(II) bioaccumulation and distribution in Rhodopseudomonas palustris

“…These models have been widely applied to many organic material degradation systems and heavy metal removal processes [30][31][32].…”
