Centesimal composition and physical-chemistry analysis of the edible mushroom Lentinus strigosus occurring in the Brazilian Amazon

Abstract

The centesimal composition and the physical and chemical analyses of Lentinus strigosus, an edible mushroom occurring in the Brazilian Amazon and produced in alternative substrates based on wood and agroindustrial residues, were evaluated. For this purpose, the C, N, pH, soluble solids, water activity, protein, lipids, total fiber, ash, carbohydrate, and energy levels were determined. The substrates were formulated from Simarouba amara Aubl. ("marupá"), Ochroma piramidale Cav. Ex. Lam. ("pau-debalsa") and Anacardium giganteum ("cajuí") sawdust and Bactris gasipaes Kunth ("pupunheira") stipe and Saccharum officinarum (sugar cane bagasse). The results indicated that the nutritional composition of L. strigosus varied with the substrate of cultivation; the protein levels found in mushrooms grown in the different substrates (18 -21.5%) varied with the substrate and was considered high; the soluble solids present in the mushrooms could have a relation with complex B hydrosoluble vitamins. L. strigosus could be considered as important food owing to its nutritional characteristics such as high protein content, metabolizable carbohydrates and fibers, and low lipids and calories content.

Food production potential of Favolus brasiliensis (Basidiomycota: Polyporaceae), an indigenous food

“…Sales-Campos et al (2011) observed that the nutritional composition of oyster mushrooms (Pleurotus ostreatus) varies depending on the substrate. Sales-Campos et al (2013) also reported effects of the substrate on the nutritional contents of Lentinus strigosus, a naturally occurring mushroom in the Amazon. In addition to the substrate, other factors can influence the nutritional composition, such as species and their varieties, lineages, degree of maturity of the mushroom, parts of the mushroom examined, among others (Sales-Campos et al, 2013).…”

Food and nutritional potential of two mushrooms native species to the Brazilian savanna (Cerrado)

“…Sales-Campos et al ( 2013) also found substrate effects on the nutritional contents of Lentinus strigosus Fr., a mushroom naturally occurring in the Amazon. Other factors in addition to the substrate can influence the nutritional composition such as species and their varieties, strains, maturity degree of the mushroom, parts of the mushroom examined, among others (Sales-Campos et al, 2013).…”

Panus lecomtei (Fr.) Corner (Agaricomycetes, Polyporales, Panaceae): primeira ocorrência no Estado do Piauí, Brasil

“… eSales-Campos et al (2013), realizados com a denominação de Lentinus strigosus, são relacionados ao cultivo em diferentes resíduos e sobre substâncias encontradas neste fungo com alto potencial no tratamento de doenças negligenciadas. No Brasil, Panus lecomtei tem sido reportado em oito Estados: Amazonas, Alagoas, Bahia, Pernambuco, Mato Grosso do Sul, Rio Grande do Sul, Santa Catarina e Paraná(Drechsler-Santos et al 2012, Vargas-Isla et al 2015.O estudo de fungos basidiomicetes no Estado do Piauí é ainda incipiente, onde poucos estudos como de Alves et al (2019) e Alves et al (2012) podem ser referidos.…”
