Removal of Heavy Metals in Cassava Mill Effluents with Saccharomyces cerevisiae isolated from Palm Wine

“…In addition, Cherlys et al [35] reported that low level of heavy metals can also be toxic to microbes and tolerance level of high concentration occurs when there is sufficient sulphur. Typically S. cerevisiae has the ability to utilize a variety of carbon and nitrogen sources however, in the absence of these nutrient sources, they could use some other synthetic chemicals [9]. This could be the reason while there was significant reduction in most of the heavy metals concentration after 15 days of treatment.…”

“…Some of the human activities leading to heavy metal in the environment include discharge of untreated or partially treated industrial wastes including sewage, drugs, oil, heavy metals, paints, pesticides and various chemical compounds into the environment especially aquatic ecosystem [9]. These heavy metals lead to environmental pollution [9,10]. Some of the heavy metals that have high environmental toxicity and health effects include lead, mercury, chromium, cadmium, copper, cadmium, nickel and zinc [3].…”

“…Heavy metals enters the environment from natural effects (such as seepage from rocks and volcanic activity) [3] and by large extent anthropogenic activities [1,[4][5][6][7][8]. Some of the human activities leading to heavy metal in the environment include discharge of untreated or partially treated industrial wastes including sewage, drugs, oil, heavy metals, paints, pesticides and various chemical compounds into the environment especially aquatic ecosystem [9]. These heavy metals lead to environmental pollution [9,10].…”

“…According to Kelewou et al [36], the merits of yeast over bacteria and filamentous fungi is that its inexpensive and readily available from different source, and can grow and adapt extreme conditions of pH, temperature and nutrients availability. 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].…”

Optimization of diazinon biodegradation from aqueous solutions by Saccharomyces cerevisiae using response surface methodology

“…Mutagenicity studies indicated that diazinon does not have negative effects on the metabolic system of S. cerevisiae (Mohn 1973; Fahrig 1974), and only at concentrations greater than 50,000 ppm can it have negligible toxic effects on S. cerevisiae (Bianchi et al 1994). Sadeghi et al (2014) used S. cerevisiae for the biological removal of carmoisine and Reactive Black 5 dyes (Sadeghi et al 2014). Fabrizio et al (1983) demonstrated that this type of yeast can biologically remove the folpet and metalaxyl fungicides and the pyrethroid and deltametrin insecticides (Fabrizio et al 1983).…”
