  • Elemental bioaccumulation and nutritional value of five species of wild growing mushrooms from South Africa.
    Food chemistry, 2020
    Co-Authors: Muvhango Rasalanavho, Roshila Moodley, Sreekantha B. Jonnalagadda
    Abstract:

    Abstract The collection of wild edible mushrooms for use is an ancient practice. In this study, the elemental concentrations in five mushrooms were compared as a function of species and geographical location. The accumulation of metals from the substrate was found to be species dependent. Mushrooms excluded As, Be, Ca, Cd, Co, Cr, Fe, Mn, Ni and Si, and accumulated elements in the following order: Amanita pantherina (K > Na > Zn > Cu > Mg); Boletus edulis (edible) (K > Cu > Zn > Se > Na > Mg); Boletus mirabilis (edible) (K > Cu > Zn > Na > Mg); Lactarius deliciosus (edible) (K > Zn > Mg); and Russula sardonia (K > Na > Zn > Cu > Mg). Statistical analysis showed soil parameters to affect elemental accumulation by edible mushrooms more than inedible ones, especially for uptake of Se by B. edulis, which was antagonistic with As and Pb in the soil. The results also showed the edible mushrooms to contain proteins (25 – 55%), carbohydrates (34 – 69%), ash (3–6.5%) and lipids (0.8–5.3%).

  • Elemental distribution including toxic elements in edible and inedible wild growing mushrooms from South Africa
    Environmental Science and Pollution Research, 2019
    Co-Authors: Muvhango Rasalanavho, Roshila Moodley, Sreekantha B. Jonnalagadda
    Abstract:

    Macro-elements (Ca, Fe, K, Mg and Na) and trace elements including some toxic (As, Be, Cd, Co, Cu, Mn, Ni, Pb, Se and Zn) were determined in edible and inedible wild-growing mushrooms ( Amanita rubescens , Auricularia polytricha , Boletus edulis , Boletus mirabilis , Clavulina cristata , Helvella crispa , Lactarius deliciosus , Suillus luteus , Termitomyces microcarpus , Termitomyces reticulatus , Termitomyces clypeatus , Termitomyces umkowaanii , Amanita foetidissima , Amanita muscaria , Amanita pantherina , Aseroe rubra , Chlorophyllum molybdites , Ganoderma lucidum , Gymnopilus junonius , Hypholoma fasciculare , Lentinus villosus , Lepista caffrorum , Pycnoporus sanguineus , Panaeolus papilionaceus , Pisolithus tinctorius , Pleurotus ostreatus , Podaxis pistillaris , Russula sardonia , Scleroderma citrinum , Scleroderma michiganense ). Analyses of samples were carried out using inductively coupled plasma-optical emission spectrometry. The elemental content in both edible and inedible mushrooms, in decreasing order, was found to be K >> Na > Ca > Mg > Fe > Mn > Zn > Cu > Se > Co > Ni > Be > Pb ≥ Cd > As. Our study revealed that the accumulation of metals from the soil is independent of whether mushrooms are edible or inedible as uptake is dependent on the soil quality and its environment. Edible mushroom species studied were found to be rich in Se (145–836% towards the RDA) with B . edulis being rich in it, C . cristata in Cu, S . luteus in Fe and H . crispa in Zn, and all contained low concentrations of toxic metals making them suitable for human consumption.

  • trace element levels of mushroom species from east black sea region of turkey
    Food Control, 2007
    Co-Authors: Mustafa Tuzen, Ertugrul Sesli, Mustafa Soylak
    Abstract:

    Abstract The levels of trace metals of mushroom samples collected from East Black Sea region of Turkey were determined by flame and graphite furnace atomic absorption spectrometry after microwave digestion method. The accuracy of the method was corrected by standard reference material (NIST SRM 1573a Tomato Leaves). The contents of investigated trace metals in mushroom samples were found to be in the range of 18.9–64.8 μg/g for copper, 53.5–130 μg/g for manganese, 44.7–198 μg/g for zinc, 187–985 μg/g for iron, 0.54–10.8 μg/g for selenium and 0.9–2.5 μg/g for cadmium. Mushrooms species in the highest levels of trace elements were found Entoloma sinuatum for Cu and Zn, Leucoagaricus leucothites for Mn, Amanita pantherina for Fe and Se, Agaricus arvensis for Cd.

  • Diversity of macrofungal genus Russula and Amanita in Hirpora Wildlife Sanctuary, Southern Kashmir Himalayas
    Biodiversitas Journal of Biological Diversity, 2012
    Co-Authors: Shauket Ahmed Pala, Abdul Hamid Wani, Riyaz Ahmad Mir
    Abstract:

    Pala SA, Wani AH, Mir RA. 2012. Diversity of macrofungal genus Russula and Amanita in Hirpora Wildlife Sanctuary, Southern Kashmir Himalayas. Biodiversitas 13: 65-71. The Hirpora Wildlife Sanctuary that extends over an area of 114 km 2 lies in the Pir Panjal range at a distance of 70 km in south-west of summer capital Srinagar. It is rich in biodiversity including macrofungal diversity. The Sanctuary has been subjected to high ecological and anthropogenic disturbance due to the construction of Mughal road which is major threat for its biodiversity. Since there is hardly any report of documentation of macrofungi from this sanctuary. In this back drop a survey was carried out during the year 2010 and 2011 to explore and invetorise macrofungal diversity of the sanctuary. During the survey a no of macrofungi were documented, among which Amanita and Russula were dominant genus represented by 7 species each. All the 14 species viz. Amanita ceciliae (Berk. & Broome) Bas. Amanita flavoconia G.F. Atk., Amanita muscaria var. formosa Pers., Amanita pantherina (Fr.) Krombh., Amanita phalloides (Fr.) Link., Amanita vaginata (Bull. ex Fr.) Vitt., Amanita virosa (Fr.) Bertillon, Russula aeruginea Fr., Russula atropurpurea (Krombh.) Britz., Russula aurea Pers., Russula cyanoxantha (Schaeff.) Fr., Russula delica Fr. Russula emetica (Schaeff. ex Fr.) Gray. and Russula nobilis Velen. are ectomycorrhizal in nature and among them Russula aeruginea Fr. is reported first time from the Kashmir.
