Bioremoval Of Cadmium Using Pseudomonas fluorescens

Cd(II) biosorption using bacterial isolates from sawdust: optimization via orthogonal array Taguchi method

“…Research has revealed that bacterial efficacy in removing heavy metals from solution varies from one to another under different temperature conditions (Kumar et al, 2010;Javanbakht et al, 2014). Some studies have produced similar results to the current study (Yan et al, 2003;Sankarammal et al, 2014). Figure 3 presents the variation of average Cd(II) uptake from solution by bacterial isolates and signal-to-noise ratio at different levels of reaction time.…”

Bioremediation of Pb and Cd contaminated soil using microorganism

“…Dafe limits for Pb and Cd content in the human body in adults who are not exposed to cadmium, blood levels of cadmium are usually less than 0.5 µg/ml, while the safe limit for lead in adults is 10 µg/dL and for children is 5 µg/dL in whole blood (Rana et al, 2018). Decrease in plant growth rate (Huang et al, 2006) Interfering with the permeability of cell membranes, toxic for microbal metabolism (Giwa & Ibitoye, 2017) Cd (Cadmium) itai-itai disease, kidney damage, emphysema, hypertension, and testicular artophy (Sankarammal et al, 2014). Nuclei acids damage, proteins denaturation, inhibit cell division and transcription, mineralization of carbon and nitrogen are inhibited (Giwa & Ibitoye, 2017) Chlorosis of the leaves, wilted and creased (Susana & Suswati, 2011) Denaturation of proteins, inhibits cell division, interferes with the activity of cell membranes, inhibits enzym activity, nucleic acids damage (Fashola et al, 2016)…”

“…Cd metal is an inorganic metal which is more toxic than Pb. Cd poisoning causes acute and chronic bodily disorder (Sankarammal et al, 2014). Based on the effects of Pb and Cd pollution which have high risk to the health of living things, efforts should be made to ensure that the concentration in the environment does not exceed the environmental quality standard threshold.…”

“…isolated Bacillus sp from sulfur springs and was shown to be able to remediate Pb (II) and Cd (II).Singh et al (2014) succeeded in isolating Pseudomonas sp from industrial waste sludge and this bacteria has potential to be a bioremediation agent. The research ofSankarammal et al (2014) conducted a study using Pseudomonas fluorescens isolated from the soil around the electroplating industry to reduce the elemental Cd. Pseudomonas fluorescens was able to reduce Cd by 99.7% at a concentration Cd 250 ppm, 99.9% at concentration of 500 ppm, 99.8% at concentration of 750 ppm, and 99.9% at concentration of 1000 ppm.…”
