Nutritional and phenolic profile of small edible fungal species Coprinellus disseminatus (pers.) J.E. Lange 1938

Abstract

The aim of this work was to investigate nutritional profile in relation to proteins, amino acids, fatty acids and mineral composition, as well as phenolic profile of small edible fungal species Coprinellus disseminatus originated from Serbia. Total protein content in the analyzed fungal species was 9.72%. Fifteen protein fractions obtained by electrophoresis were identified in a range from 1.6 to 63.6 kDa. Chip-based separations showed the presence of protein fraction with molecular weight of 27.5 kDa that could possess antifungal activity. The total essential and non-essential amino acid contents were 29.57 and 96.69 mg/g DW, respectively. Among the essential amino acids, leucine was the most abundant. Fatty acid composition of C. disseminatus showed that polyunsaturated fatty acids (PUFA, 59.1% of total FA) predominated over saturated fatty acids (SFA, 23.1% of total FA) and monounsaturated fatty acids (MUFA, 17.9% of total FA). The dominant fatty acids were linoleic acid (56.6%), palmitic acid (13.9%), and oleic acid (12.0%). The most abundant macroelement in C. disseminatus was potassium, followed by calcium and magnesium, while iron dominated in microelements. Eight phenolic compounds were quantified in methanolic extract of C. disseminatus by LC-MS/MS with the highest amount of p-hydroxybenzoic acid and p-coumaric acid reaching 9.46 ± 0.2 µg/g DW and 7.8 ± 0.1 µg/g DW, respectively.

Exploration of study objects on the potential of wild mushrooms growing on oil palm empty bunches for learning in the subject of IPAS project at vocational school

“…The potential that mushrooms have for food sources in the context of edible mushrooms is that they have macronutrient content (carbohydrates, protein, fat, fiber, and ash content), micronutrient content (vitamin A, vitamin B, vitamin B12, vitamin C, Calcium, Potassium, Magnesium, Phosphorus, Iron, Zinc, and Manganese), essential and non-essential amino acid content, and saturated fatty acid and unsaturated fatty acid content. Potential medicinal ingredients are owned by edible mushrooms because they contain antioxidant activity with alkaloid, phenolic, flavonoid, and β-glucan components, anticancer activity, antibacterial activity with active fraction components against several kinds of bacteria including E.coli bacteria, antitoxic activity, antiviral, antidiabetic activity from the presence of hypoglycemic effects, anti-inflammatory activity, anti-aging activity, immunomodulatory activity, as a substitute for antibiotics when treating infections, therapeutic treatment of depression, and anxiety disorders, Alzheimer's disease, and others (Akata et al, 2012;Akdogan et al, 2014;Bao et al, 2013;Chang & Miles, 2004;Kayode et al, 2016;Nosalova et al, 2001;Novakovic et al, 2016;Novaković et al, 2018;Shomali et al, 2019;Wong et al, 2020). Some types of mushrooms have natural insecticidal activity from the toxin compounds in them which makes extracts from these mushrooms potential insecticides (Park et al, 2020).…”

Heavy Metals Content in Foliar Litter and Branches of Quercus petraea (Matt.) Liebl. and Quercus robur L. Observed at Two ICP Forests Monitoring Plots

“…Determination of selected microelements (Zn, Mn, Cu and Fe) was done in digested solutions that were made from powdered litterfall samples using standard method of microwave assisted digestion (D series; Milestone, Bergamo, Italy), while the quantification of metals was performed by Atomic Absorption Spectrophotometer in a flame regimen (model FS AAS240/GTA120, Varian -AAS, California, US). Approximately 0.3 g of oven-dried material were ground and homogenized in a laboratory mill and then digested in 10 ml of nitric acid and 2 ml 30% (w/v) hydrogen peroxide using a microwave-assisted digestion system (D series; Milestone, Bergamo, Italy) for 45 min at 180°C (900 W) [20]. Filtrates were then diluted to 25 ml with deionizer water.…”

Macrofungi Inventaritation at the Pine Forest of Kragilan, Magelang

“…The stem has a cylindrical shape that is hollow and easily brittle (Figure 11). Coprinellus disseminatus is a saprophytic fungus that can be used as food with some nutritional content, such as protein, amino acids, fatty acids, and mineral components [42]. Besides, it can be used as an anti-cancer [43,44].…”
