“…The analysis of the metal concentration of these and related mushrooms was previously published (García et al, 2009;Çayır et al, 2010;Kalač, 2010;Ayaz et al, 2011;Sarikurkcu et al, 2011). Compared to those studies, the results of mineral content in our mushroom samples are in accordance with previous results, with small differences in the content of Zn, Mn and Cd.…”

“…The importance of mushrooms in the ecosystem can be described by their ability to biodegrade the substrate and therefore use the wastes of agricultural production (Sarikurkcu et al 2011). In several countries, there is a well-established consumer acceptance of cultivated mushrooms, such as Agaricus bisporus, Pleurotus species, Lentinus edodes and others (Diez and Alvarez 2001).…”

“…Besides their nutritional values, mushrooms possess medicinal proprieties in prevention of some diseases, such as hypertension and cancer (Manzi et al 2001). Although there were several studies carried out in several countries on metals concentrations in the fruiting bodies of edible wild grown and cultivated mushrooms (Tuzen et al 2007;Sesli et al 2008;Baslar et al 2009;Radulescu et al 2010;Sarikurkcu et al 2011;Zhu et al 2011;Sen et al 2012;Okwulehie and Ogoke 2013;Obodai et al 2014;Dulay et al 2015), however, such studies are still very scarce in Ethiopia. Therefore, initiation of such study for better understanding of the types of mushrooms cultivated and consumed in the country in relation to the essential and non-essential metals is very much demanding and timely.…”

Background: Fruiting bodies of two oyster mushroom (Pleurotus ostreatus and Pleurotus florida) species and their respective substrate samples cultivated and collected from the Mushroom Research, Production and Training Laboratory of the Haramaya University, Ethiopia, were analyzed for essential and non-essential metals, viz., Cu, Fe, Zn, Mn, Cd and Pb contents by flame atomic absorption spectrometry after digestion employing dry, wet and microwave digestion techniques. Concentrations of the analyzed metals were expressed on a dry weight basis (mg/kg). Results: The mean metal concentration (mg/kg in dry weight) in the mushroom and respective substrate samples, respectively; for Pleurotus ostreatus were: Cu (51.19, 48.97), Fe (220.87, 299.51), Zn (89.68, 62.55) and Mn (47.55, 58.32). The mean metal concentration (mg/kg in dry weight) in mushroom and the respective substrate samples, respectively, for Pleurotus florida were: Cu (53.56, 51.87), Fe (243.92, 265.23), Zn (95.26, 64.25) and Mn (41.29, 62.55). However, Cd and Pb was not detected in both mushroom and substrate samples. The bio-accumulation factor of the heavy metals was calculated and a highest accumulation of Cu and Zn from substrate was observed for all the analyzed mushrooms samples. The observed results were also compared with the reported results.

“…From these studies, Acharya et al [20], identified the antioxidant effect of the ethanolic extract of Auricularia auricula in their study. [21] have identified the antioxidant potential of Auricularia auricula-judae mushroom in their study. Xu et al [22], studied the antioxidant potential of Auricularia auricula.…”

Several mushroom species are consumed by collecting from the nature or in cultured form for their nutritional and medical characteristics. The objective of the present study is to determine antioxidant activities, DNA-protective activities, total antioxidant status (TAS), total oxidant status (TOS), oxidative stress indices (OSI) and Fe, Mg, Zn, Cu, Na and Ca content in Auricularia auricula (L.) Underw. and Trametes versicolor (L.) Lloyd mushroom species. Mushroom ethanol extracts were obtained and antioxidant activities with DPPH method, TAS, TOS and OSI values with Rel Assay Diagnostics kits, and DNA protective activities using pBR322 supercoil DNA were identified. Furthermore, Fe, Mg, Zn, Cu, Na and Ca contents were determined with atomic absorption spectrophotometer. It was determined that antioxidant potential of mushroom ethanol extracts were low compared to the standard and they did not have DNAprotective activities. It was also observed that the mushrooms have variable element content, and have similar TAS, TOS and OSI levels. High OSI values found in both mushroom species showed that these mushroom are unhealthy. Thus, it was recommended to demonstrate caution in consumption of mushrooms collected in these regions. However, it was also considered that the mushroom samples collected from regions with adequate OSI values could be used as antioxidant. IntroductıonThe usage of various foods and natural products for therapeutic purposes has a long history [1]. Since early times, mushrooms have been an important nutrient for humans and have had significant medical values [2,3]. The number of mushroom species is estimated to be around 140,000 and only 10% of these (about 14,000) have been designated [4]. Today, along with the increase in molecular studies, their use in biological warfare as well as in the production of antibiotic and other pharmacological products has increased [5]. In addition to immune system booster, antitumor, antibacterial, antiviral and anti-mutagenic effects, it is also known that mushrooms are effective in prevention and treatment of diseases such as hypertension and hypercholesterolemia [6][7][8]. Macro-fungi are a significant nutritional supplement for humans. However, several fungus species accumulate both important nutritional elements and heavy metals in their fruit bodies [9]. Although living organisms need certain elements such as iron, cobalt, copper, manganese, chrome and zinc in trace amounts, excessive amounts of these elements create toxic effects on these living organisms [10]. Thus, regardless of the purpose of it's use, it is of utmost importance to determine metal concentrations in the mushrooms before consumption.Oxidative stress occurs as a result of the imbalance between reactive oxygen species (ROS) and antioxidant defense produced in living organisms [11]. ROS are highly reactive O 2 metabolites that include superoxideradical, hydrogen peroxide and hydroxyl radical. The ROS causes considerable injury to DNA, protein and lipid and it is claimed that this in...
