“…Similar findings were reported by Hatvani and Mé cs (2003) who established for Lentinula edodes (Basidiomycota) the following sequence of decreasing toxicity: Cd 2+ (0.0087), Zn 2+ (0.62) and Pb 2+ (2.7) mM causing 50% inhibition of mycelial growth. Fungal strains of Heliscus lugdunensis and Verticillium cf alboatrum exhibited a higher tolerance against zinc than against cadmium (Jaeckel et al 2005). The studies of lead and cadmium tolerance of Corollospora lacera and Monodictys pelagica proved than Cd 2+ has a stronger toxic effect than Pb 2+ (Taboski et al 2005).…”

The influence of cadmium, zinc and lead on fungal emulsifier synthesis and on the growth of filamentous fungus Curvularia lunata has been studied. Tolerance to heavy metals established for C. lunata was additionally compared with the sensitivity exhibited by strains of Curvularia tuberculata and Paecilomyces marquandii-fungi which do not secrete compounds of emulsifying activity. Although C. lunata, as the only one out of all studied fungi, exhibited the lowest tolerance to heavy metals when grown on a solid medium (in conditions preventing emulsifier synthesis), it manifested the highest tolerance in liquid culture - in conditions allowing exopolymer production. Cadmium, zinc and lead presented in liquid medium up to a concentration of 15 mM had no negative effect on C. lunata growth and stimulated emulsifier synthesis. In the presence of 15 mM of heavy metals, both the emulsifier and 24-h-old growing mycelium exhibited maximum sorption capacities, which were determined as 18.2 +/- 2.67, 156.1 +/- 10.32 mg g(-1) for Cd2+, 22.2 +/- 3.40, 95.2 +/- 14.21 mg g(-1) for Zn2+ and 51.1 +/- 1.85, 230.0 +/- 28.47 mg g(-1) for Pb2+ respectively. The results obtained by us in this work indicate that the emulsifier acts as a protective compound increasing the ability of C. lunata to survive in heavy metal polluted environment. Enhancement of exopolymer synthesis in the presence of Cd2+, Zn2+ and Pb2+ may also suggest, at least to some extent, a metal-specific nature of emulsifier production in C. lunata. Due to accumulation capability and tolerance to heavy metals, C. lunata mycelium surrounded by the emulsifier could be applied for toxic metal removal.

“…accumulates copper and zinc as micronutrients. Along with these micronutrients, it capable to accumulate non-nutrient metals likes nickel, cadmium, lead, chromium in amounts higher than the nutritional requirement (Jaeckel et al, 2005). Metals uptake by living fungi depends on species, culture conditions, metal concentration and cells in the solution (Melgar et al, 2007).…”

Potential Saccharomyces cerevisiae was isolated from paper effluent for bioremediation of heavy metals. Morphological studies, physiological tests and molecular characterization confirmed isolated yeast colony was S. cerevisiae. S. cerevisiae has showed high biosorption of Cd 2 + (67%), followed by Pb. SEM image of heavy metals treated S. cerevisiae showed patches of accumulated heavy metals and ED's spectrum of S. cerevisiae treated with heavy metals contained metal peaks. Elemental analysis by EDS confirmed that ion exchange mainly involved in heavy metals biosorption by S. cerevisiae. Optimization of parameters made maximum biosorption of heavy metals. The pH 4.0-5.0, temperature 20-25°C and contact time of 60 minute was found optimal for heavy metals biosorption. The metal biosorption was found maximum in single metal system compared to multi metal ions. Pre-treatment method enhanced the metal biosorption. Sorption isotherm studies fit into the model of Langmuir isotherm compared to Freundlich isotherm.

“…Furthermore S. cerevisiae have been widely used in the remediation of toxicants or biodegradation of basic textile dye (Basic Green 4 and Basic Yellow 2) [36], textile dyes of carmoisine and reactive black 5 [9], industrial effluents [33], textile effluents [37], non-dairy creamer wastewater [38] pharmaceutical effluents [39], tannery effluents [34] and palm oil mill effluents [40]. The use of S. cerevisiae could be due to their ability to bioaccumulation heavy metals such as copper, zinc, nickel, cadmium, lead, chromium [3, 35,41]. Specifically S. cerevisiae has phosphate, amino, carboxyl and hydroxyl groups in its cell wall, which are responsible for their potentials in the remediation of heavy metals from the environment [35,42].…”

Nigeria is World leading producer of cassava accounting for about 20% of global output. Rudimentary equipment is used for cassava processing into several products such as high quality cassava flour by smallholders that dominate the cassava processing sector in Nigeria. The properties of the wastewater (cassava mill effluents) often exceed the limits for effluents to be discharge into the environment (land and surface water) as specified by Federal Environmental Protection Agency. Cassava mill effluents induce toxicological effects on the environment and its associated biota such as fisheries, flora and fauna as well as humans. This study evaluated the capacity of Saccharomyces cerevisiae isolated from palm wine to remove heavy metals in cassava mill effluents. The S. cerevisiae was identified using conventional microbiological techniques based on their cultural, morphological and physiological/biochemical characteristics. S. cerevisiae was inoculated into the sterile effluent and incubated for 15 days and triplicate sample were withdrawn at 5 days interval for analysis. The samples were prepared and analyzed using flame atomic adsorption spectrometry. Results showed a decline by 44.52%, 26.26%, 51.54%, 43.20% and 65.19% for copper, zinc, manganese, iron and nickel respectively. The findings of this study showed that S. cerevisiae is a potential microorganism for the remediation of heavy metals in cassava mill effluents. Keywords:
