Hot alkali‐extracted antioxidative crude polysaccharide from a novel mushroom enhances immune response via TLR‐mediated NF‐κB activation: A strategy for full utilization of a neglected tribal food

Somanjana Khatua, Swarnendu Chandra, Krishnendu Acharya

Journal of Food Biochemistry > 45 > 1 > n/a - n/a

Mushroom polysaccharides have been revered for decades as incredibly versatile compounds suitable for application in biomedical, pharmaceutical, food, and cosmetic industries. In that essence Russula alatoreticula, a traditionally appraised unique macrofungus, has earlier been explored to contain functional macromolecules elicited by hydrothermal and cold alkali systems. Remnants of that multistep...

Nongreen revolution: a case study of wild-grown edible mushroom

Ismail Bulent Gurbuz

Environmental Science and Pollution Research > 2019 > 26 > 8 > 7954-7959

Mushroom’s biological content has a positive effect on human welfare which is called “nongreen revolution”. It has an economic and social component that provides long-term food nutrition, environmental conservation, and regeneration of valuable resources. This article provides evidence that mushrooms can be a healthy food alternative to meat. In this study, analyzed data was collected from Marmara...

Environmental Science and Pollution Research > 2019 > 26 > 6 > 5422-5434

The mobility (fractionation) of rare earth elements (REEs) and their possible impacts on ecosystems are still relatively unknown. Soil samples were collected from two sites in central Serbia, an unpolluted mountain region (site 1) and a forest near a city (site 2). In order to investigate REE fractions (acid-soluble/exchangeable, reducible, oxidizable, and residual) in soils, BCR sequential extraction...

In vitro ectomycorrhization of Tricholoma matsutake strains is differentially affected by soil type

Chika Saito, Wakana Ogawa, Hisayasu Kobayashi, Takashi Yamanaka, more

Mycoscience > 2018 > 59 > 1 > 89-97

The Japanese delicacy Tricholoma matsutake has been conducted in vitro ectomycorrhizal syntheses for more than 20 y. The development of its ectomycorrhizal structures varies among experimental systems. Here, we examined the effects of soil-fungus interactions on the early stage of in vitro T. matsutake ectomycorrhization. Axenic Pinus densiflora seedlings were transplanted into autoclaved natural...

Influence of extraction parameters on physico-chemical characters and antioxidant activity of water soluble polysaccharides from Macrocybe gigantea (Massee) Pegler & Lodge

Somanjana Khatua, Krishnendu Acharya

Journal of Food Science and Technology > 2016 > 53 > 4 > 1878-1888

Polysaccharides from mushrooms are potentially active pharmaceutical ingredients and their action is dependent upon conformation, composition, size etc. In this context, three water soluble crude polysaccharide rich fractions viz. hot water extracted polysaccharide (HWP), cold alkaline extracted polysaccharide (CAP) and hot alkaline extracted polysaccharide (HAP) have been isolated using varying extraction...

Study of mercury content in wild edible mushrooms and its contribution to the Provisional Tolerable Weekly Intake in Spain

Carlos Ostos, Fernando Pérez-Rodríguez, Baldomero Moreno Arroyo, Rafael Moreno-Rojas

Journal of Food Composition and Analysis > 2015 > 37 > Complete > 136-142

The study determined total mercury (Hg) content of 10 wild edible mushroom species collected in southern Spain. Results indicated that the highest Hg level corresponded to Boletus aereus with 10.28±2.92mg/kg DW (dry weight), while the lowest Hg level was found in Terfezia arenaria with 0.09±0.08mg/kg DW. Regarding the anatomic parts of the mushrooms, caps showed significantly higher Hg concentrations...

Food Packaging and Shelf Life > 2014 > 1 > 2 > 179-189

Lactarius deliciosus mushrooms were packed in two modified atmospheres: (i) batch 1 (3.7% O ₂ +8.3% CO ₂ ) and (ii) batch 2 (9.0% O ₂ +4.5% CO ₂ ), and compared with a control. Mushrooms were stored at 2±1°C and sampling was carried out after 0, 4, 7 and 9 days. Firmness and weight decrease were not significant during storage. Browning significantly increased (P<0...

Mineral element content in prized matsutake mushroom (Tricholoma matsutake) collected in China

Tao Li, Ji Zhang, Tao Shen, Yun-Dong Shi, more

Chemical Papers > 2013 > 67 > 6 > 672-676

The contents of Ca, Cu, Fe, K, Mg, Mn, Na, and Zn in fruiting bodies of the highly-prized matsutake mushroom (Tricholoma matsutake) from twelve widely separated sites in Southwest China were determined using AAS. The results for dried mushrooms showed that the mean contents (mg kg⁻¹) of the determined elements decreased in the following order: K (440–2000), Na (150–740), Ca (90–850), Mg (90–680),...

Ecotoxicology and Environmental Safety > 2012 > 78 > Complete > 184-194

The objectives of this survey were (1) to assess for the first time the Cd, Cu, Cr, Fe, Mn, Ni, Pb and Zn contents in wild edible mushrooms (Russula delica, Lactarius sanguifluus, Lactarius semisanguifluus, Lactarius deliciosus, Suillus bellinii) from the island of Lesvos, (2) to investigate the metals' variability among the species, as well as in relation to the chemical composition of the underlying...

Isolation and structural elucidation of a water-soluble polysaccharide (PS-I) of a wild edible mushroom, Termitomyces striatus

Soumitra Mondal, Indranil Chakraborty, Dilip Rout, Syed S. Islam

Carbohydrate Research > 2006 > 341 > 7 > 878-886

A heteropolysaccharide (PS-I), isolated from the hot aqueous extract of an edible mushroom, Termitomyces striatus, is composed of d-glucose, d-galactose, d-mannose and l-fucose in a molar ratio 2:1:1:1. Structural investigation of the native as well as the Smith-degraded polysaccharide was carried out using methylation analysis, periodate oxidation studies and 1D and 2D NMR spectroscopy, and the repeating...

Fatty acid composition in some wild edible mushrooms growing in the middle Black Sea region of Turkey

Necmettin Yilmaz, Mehtap Solmaz, İbrahim Türkekul, Mahfuz Elmastaş

Food Chemistry > 2006 > 99 > 1 > 168-174

The fatty acids in Agaricus bisporus, Agaricus campestris, Boletus edulis, Coprinus comatus, Pleurotus ostreatus, Oudemansiella radicata and Armillaria mellea species were obtained by a Soxtec system extracted with chloroform/methanol (2:1) and derivation of their methyl ester forms. The fatty acids were identified and quantified by gas chromatography. The fatty acid compositions mushrooms were studied...
