“…Cd is carcinogenic, embryotoxic, teratogenic, and mutagenic and may cause hyperglycemia, reduced immunopotency, and anemia, due to its interference with iron metabolism (Sanders 1986). The toxicity of Cd has also been well documented in selective types of almost all major phyla of eukaryotes (Unger and Roesijadi 1996;Coeurdassier et al 2004).…”

This study is aimed at assessing the ability of metal-resistant yeast, Candida tropicalis, to uptake cadmium from the liquid medium. The minimum inhibitory concentration of Cd 2+ against C. tropicalis was 2,800 mg L −1 . The yeast also showed tolerance towards Zn 2+ (3,100 mg L −1 ), Ni 2+ (3,000 mg L −1 ), Hg 2+ (2,400 mg L −1 ), Cu 2+ (2,300 mg L −1 ), Cr 6+ (2,000 mg L −1 ), and Pb 2+ (1,200 mg L −1 ). The yeast isolate showed typical growth curves, but low specific rate of growth was observed in the presence of cadmium. The yeast isolate showed optimum growth at 30°C and pH 7. The metal processing ability of the isolate was determined in a medium containing 100 mg L −1 of Cd 2+ . C. tropicalis could decline Cd 2+ 57%, 69%, and 80% from the medium after 48, 96, and 144 h, respectively. C. tropicalis was also able to remove Cd 2+ 56% and 73% from the wastewater after 6 and 12 days, respectively. Cd produced an increase in glutathione (GSH) and non-protein thiol levels by 146.15% and 59.67% at 100 mg L −1 concentration, respectively. Metal tolerance and accumulation together with changes in the GSH status and non-protein thiols under Cd exposure were studied in C. tropicalis.

“…It enters the human food chain through plants, smoking materials and diet (Dabeka & Mckenzie 1992;Kalcher et al 1993). Cadmium is a potent carcinogen, embryogen, teratogen and mutagen and it may cause hyperglycemia, reduced immuno-potency and anemia, due to interference with iron metabolism (Sanders 1986). Cadmium and Pb, though non-essential and non-beneficial, are considered highly toxic to plants, animals and microbes (Ajmal et al 1998).…”

The use of microorganisms to remove heavy metals from industrial effluent is an area of extensive research and development. Attempts have been made to isolate and characterize metal-resistant microorganisms from treated oil mill industry effluent wastewater samples. The metal-resistant organisms that showed values of minimum inhibitory concentration towards metals (Cd, Cr, Ni and Pb) ranging from 100 to 800 ppm level were screened. A potent metal-resistant organism, isolate BC15 from the wastewater samples was tentatively identified as Pseudomonas sp. Detailed analysis of morphological, biochemical and 16S rDNA sequence of the isolate revealed that it is closely related to Pseudomonas aeruginosa (94%). Pseudomonas BC15 was capable of absorbing 93% Ni, 65% Pb, 50% Cd and 30% Cr within 48 h from the medium containing 100 mg of each heavy metal per liter. The multiple metal tolerance of this strain was also associated with resistance to antibiotics such as ampicillin, tetracycline, chloramphenicol, erythromycin, kanamycin and streptomycin.

The alga, Distigma proteus, isolated from industrial wastewater showed tolerance against Cd 2+ (8.0 lg/ml), Cr 6+ (12 lg/ml), Pb 2+ (15 lg/ml) and Cu 2+ (10 lg/ml). The metal ions slowed down the growth of the organism after 4-5 days of exposure. The reduction in cell population was 90% for Cu 2+ , 84% for Cd 2+ , 71% for Cr 6+ , and 63% for Pb 2+ after 8 days of metal stress. The order of resistance to heavy metal, in terms of reduction in the cellular population, was Cu 2+ > Cd 2+ > Cr 6+ > Pb 2+ . Chromium-and cadmium-processing capabilities of the alga were worked out for its potential use as a bioremediator of wastewater. The reduction in the amount of Cr 6+ after 2, 4, 6 and 8 days of algal culture containing 5.0 lg Cr 6+ ml -1 of culture medium was 77, 85, 92 and 97%, respectively. Distigma could also remove 48% Cd 2+ after 2 days, 68% after 4 days, 80% after 6 days and 90% after 8 days from the medium. The heavy metal uptake ability of Distigma can be exploited for metal detoxification and environmental clean-up operations.
