Production and Nutritional Composition of King Oyster Culinary-Medicinal Mushroom Pleurotus eryngii (Agaricomycetes) Biomass from Brazil.

The present study aimed to evaluate the nutritional composition and production of mycelial biomass of Pleurotus eryngii in different culture media, formulated with infusion of purple-skinned sweet potato, glucose concentrations, and the presence or absence of yeast extract. The mushroom was grown for 15 days at 25°C and 150 rpm. The best production of mycelial biomass occurred in the culture medium with 40 g/L of glucose plus yeast extract.

Physicochemical and sensory analysis of craft beer made with soursop (Annona muricata L.).

Background: Owing to the scarcity of studies related to the use of soursop (Annona muricata L.) in the elaboration of craft beers, this study aimed to elaborate a soursop fruit beer using an artisanal method.

Methods: To determine the most favorable moment for the inclusion of the fruit, the soursop pulp was added experimentally in three stages of the process: during the boiling of the wort (C01); on the 3rd day of fermentation (C02); during carbonation, with the use of soursop extract (C03).

Production of mycelial biomass by the Amazonian edible mushroom Pleurotus albidus.

Edible mushroom species are considered as an adequate source of food in a healthy diet due to high content of protein, fiber, vitamins, and a variety of minerals. The representatives of Pleurotus genus are characterized by distinct gastronomic, nutritional, and medicinal properties among the edible mushrooms commercialized worldwide. In the present study, the growth of mycelial biomass of Pleurotus albidus cultivated in submerged fermentation was evaluated.

QuEChERS-based method for the multiresidue analysis of pesticides in beeswax by LC-MS/MS and GC×GC-TOF.

The validation of an analytical procedure for the determination of pesticide residues in beeswax, an interesting matrix for environmental pollution monitoring, is presented. Using the QuEChERS template, the impacts of wax particle size, sample amount, and cleanup procedure (water addition, dispersive solid phase extraction, freeze-out, and combinations thereof) on extraction yield and coextractive load were studied. Sample preparation through liquid-liquid partitioning between acetonitrile and melted wax (∼80 °C), followed by freeze-out and primary-secondary amine dispersive cleanup, was performed on incurred and pesticide-free samples for 51 residues.

Mycelial biomass and biochemical properties of proteases produced by Lentinus citrinus DPUA 1535 (Higher Basidiomycetes) in submerged cultivation.

The cultivation of Lentinus citrinus for mycelial biomass and protease production under different carbon and nitrogen sources was studied in submerged cultivation. The nutritional source concentration for protease production was evaluated using a full factorial design. For mycelial biomass maltose (4.

The influence of different submerged cultivation conditions on mycelial biomass and protease production by Lentinus citrinus Walleyn et Rammeloo DPUA 1535 (Agaricomycetideae).

The influence of different carbon and nitrogen sources, pH of the culture medium, and temperature and period of cultivation on mycelial biomass production and protease activity by Lentinus citrinus DPUA 1535 were investigated in submerged culture. A 2(5) full factorial design with three central points was employed, and the results showed that at a significance level of 95% only nitrogen source and temperature were statistically significant for mycelial biomass production. On the other hand, for protease activity all factors and some interactions were significant, and the temperature and nitrogen source had the most significant effect.
