“…One study was conducted to examine the elimination of Cd from wastewater by using C. tropicalis. The result showed that C. tropicalis was capable of eliminating Cd by about 40 % after treatments for 6 days ( Bhattacharyya et al, 2022 ).…”

“…It was then re-suspended in the eluent solution (100ml) and agitated for 2.5h. Cd(II) concentration in the liquid phase was measured by Atomic Absorption Spectroscopy (Shimadzu AA-7000, Japan) 7 . The eluent used in the assay was 0.2(M) HCl.…”

“…Various conventional removal methods have been practiced to remove cadmium and other heavy metals from contaminated water since a long time. The worth mentioning are chemical precipitation, reverse osmosis, adsorption, reverse osmosis, ion exchange and other physicochemical methods 6,7 . With time these methods have become outdated and suffer from severe drawbacks including high operational costs, continual monitoring, inefficiency in toxicant removal from dilute solutions and generation of toxic sludge [8][9][10] .…”

Cadmium is one of the most dreadful heavy metals and is becoming a major toxicant in ground water with increasing concentration above the WHO Guidelines in drinking water (0.003ppm). The conventional physico-chemical remediation techniques are not favorable in removing the contaminants such as Cd(II) fruitfully. Bio-based techniques used in Cd(II) removal from contaminated water provide cheap, eco-friendly and efficient means of environmental remediation. The present study is aimed at determining the optimized nutritional conditions for the optimal growth and Cd(II) remediation capacity for a developed Cd(II) resistant yeast strain named Candida tropicalis XTA 1874 isolated from contaminated water-body in West Bengal. By analyzing the optimization conditions, a synthetic medium was developed and the composition has been given in the main text. The biosorption process followed pseudo second order kinetics proving chemisorption as the rate limiting step in the adsorption process. The equilibrium biosorption of Cd(II) by the strain was fitted to the Langmuir model and hence the biosorption was a monolayer process both before and after optimization. The strain showed much better Cd(II) adsorption capacity under the optimized nutritional conditions (qmax=847.476±0.008 mg/g). The above findings amply demonstrated the strain to be an effective biosorbent in removing Cd(II) from contaminated water.
