“…Ni, THg and Al were notably higher than those previously recorded (Table ). Nickel is a transition metal, often released into the environment by industries such as oil and coal burning power plants, waste incinerators and factories producing Ni alloys and products (Joho et al ., ; Saxena and Bhattacharyya, ). Nickel is also an essential trace element in plants and some animals (Joho et al ., ), although it is known to be haematotoxic, immunotoxic, neurotoxic and carcinogenic to mammals (Das et al ., ) and has detrimental effects on gastrointestinal, muscoskeletal, hepatic, renal, dermal, ocular and reproductive systems (Eisler, ).…”

Cetaceans, occupying the top levels in marine food chains, are vulnerable to elevated levels of potentially toxic trace elements, such as aluminium (Al), mercury (Hg) and nickel (Ni). Negative effects associated with these toxic metals include infection by opportunistic microbial invaders. To corroborate the link between the presence of cutaneous fungal invaders and trace element levels, skin samples from 40 stranded false killer whales (FKWs) were analysed using culture techniques and inductively coupled plasma-mass spectroscopy. Twenty-two skin samples yielded 18 clinically relevant fungal species. While evidence for bioaccumulation of Hg in the skin of the FKWs was observed, a strong link was found to exist between the occurrence of opportunistic fungal invaders and higher Al : Se and Al : Zn ratios. This study provides indications that elevated levels of some toxic metals, such as Al, contribute to immunotoxicity rendering FKWs susceptible to colonization by cutaneous opportunistic fungal invaders.

“…Microbes can develop a high resistance to heavy metals by a variety of mechanisms to remove ions, such as adsorption to cell surfaces, complexation by exopolysaccharides, intracellular accumulation or precipitation [18, 19]. That's why isolating microbes from polluted environments would represent an appropriate practice to select metal-resistant strains that could be used for heavy metal removal and bioremediation purposes [4, 20].…”

An indigenous bacterium, Bacillus REP02, was isolated from locally sourced chromium electroplating industrial effluents. Response surface methodology was employed to optimize the five critical medium parameters responsible for higher % Cr2+ removal by the bacterium Bacillus REP02. A three-level Box-Behnken factorial design was used to optimize K2HPO4, yeast extract, MgSO4, NH4NO3, and dextrose for Cr2+ removal. A coefficient of determination (R 2) value (0.93), model F-value (3.92) and its low P-value (F < 0.0008) along with lower value of coefficient of variation (5.39) indicated the fitness of response surface quadratic model during the present study. At optimum parameters of K2HPO4 (0.6 g L−1), yeast extract (5.5 g L−1), MgSO4 (0.04 g L−1), NH4NO3 (0.20 g L−1), and dextrose (12.50 g L−1), the model predicted 98.86% Cr2+ removal, and experimentally, 99.08% Cr2+ removal was found.

“…Chitin is a very important structural component of fungal cell wall which is an effective biosorbent for chemicals and radionuclides (Gadd, 2008). Micro-organisms (fungi) can develop high resistance to dye and metals through adsorption to cell surface, complexation by exo-polysaccharides, intracellular accumulation, and precipitation, ( Saxena, 2006).…”

Aim: The present study was done to evaluate the effect of the dye basic fuchsin (BF) on soil mycobiota with an aim to mark out the fungal strains which might be able to remove triphenylmethane dyes from effluent by adsorption. Methodology: Pot experiments were conducted during the study and different concentration (500, 750 and 1000 ppm) of Basic fuschin dye were used on soil mycobiota. Soils treated with different concentration of the solution of basic fuchsin were screened for fungal isolates. Results: A. flavus and A. niger could survive basic fuchsin treatment in the soil to a reasonable extent and their sizable populations were isolated from BF treated soil throughout the period of 90 days, even from the soil treated with as high as 1000 ppm concentration of the dye. Discussion: The genus Aspergillus and Aspergillus niger could survive in the higher concentration of dye. It can tolerate the 1000 ppm of Basic fuschin dye and it may be helpful to overcome water pollution by removing color contaminants from water bodies through biosorption.
