[Ab] Resumo:Analysis of fungal secretomes is a prospection tool for the discovery of new catalysts with biotechnological applications. Since enzyme secretion is strongly modulated by environmental factors, evaluation of growth conditions is of utmost importance to achieve optimal enzyme production. In this work, a nonsequenced wood-rotting fungus, Lentinus crinitus, was used for secretome analysis by enzymatic assays and a proteomics approach. Enzyme production was assessed after the fungus was cultured in seven different carbon sources and three nitrogen-containing compounds. The biomass yields and secreted protein arrays differed drastically among growing conditions. A mixture of secreted extracts derived from solid and liquid cultures was inspected by shotgun mass spectrometry and two-dimensional gel electrophoresis (2-DE) prior to analysis via LC-MS/MS. Proteins were identified using mass spectrometry (MS)-driven BLAST. The spectrum of secreted proteins comprised CAZymes, oxidase/reductases, proteases, and lipase/esterases. Although preseparation by 2-DE improved the number of identifications (162) compared with the shotgun approach (98 identifications), the two strategies revealed similar protein patterns. Culture media with reduced water content stimulated the expression of oxidases/reductases, while hydrolases were induced during submerged fermentation. The diversity of proteins observed within both the CAZyme and oxidoreductase groups revealed in this fungus a powerful arsenal of enzymes dedicated to the breakdown and consumption of lignocellulose.

[Ab] Resumo:We compared cold and hot wood extracts of 3 endemic Siberian trees-namely, Prunus padus (bird cherry), Populus tremula (aspen), and Betula sp. (birch)-on biomass production and laccase and peroxidase secretion in submerged cultures by the medicinal mushroom Lentinus edodes. Of the conditions tested, only hot Prunus extracts stimulated biomass production, whereas all extracts stimulated laccase and peroxidase secretion, albeit to different extents. A large, differential stimulation of manganese peroxidase was observed by hot Prunus extracts. The results highlight important differences between tree species in the stimulation of biomass and enzyme production by L. edodes and point to potentially interesting stimulatory factors present in hot Prunus extracts. These findings are of relevance in the use of L. edodes for medicinal or biotechnological applications.

[Ab] Resumo:Polyporoid and lentinoid fungi contain the important producers of substances having immunomodulatory, antitumoral, antiviral, and antihyperlipidemic effects. The discovery of several phylogenetic lines within the lentinoid-polyporoid continuum will help with target metabolomic analysis of species still not studied in pharmacological respects. The purpose of the present work was to increase a resolution in the lentinoid-polyporoid phylogenetic zone by means of selection of both the main representatives of Lentinus-related genera and poorly known/intermediate taxa such as Lentinus suavissimus, Neofavolus spp., and the resupinate part of Polyporus (genera Perenniporia and Pachykytospora) in the context of the basic structure of the Polyporales tree. The molecular phylogeny of highlighting all the polyporoid and lentinoid nodes was reconstructed using nLSU ITS rDNA and TEF datasets. The data obtained from ITS, TEF, and LSU coincide in support of core Polyporaceae of 10 clades corresponded to the generic level and 7 of these (Cerioporus, Cladomeris, Favolus, Lentinus, Neofavolus, Picipes, and Polyporus s.str.) contain generic units characterized by polyporoid or lentinoid morphotypes. The other 2 clades containing lentinoid taxa are outside the core Polyporaceae, namely Panus (Meruliaceae, Polyporales) and Neolentinus (Gloeophyllaceae, Gloeophyllales). A new genus, Picipes, is described and 25 new combinations are proposed.

[Ab] Resumo:Lytic polysaccharide monooxygenases (LPMOs) are copper-containing enzymes that oxidatively break down recalcitrant polysaccharides such as cellulose and chitin. Since their discovery, LPMOs have become integral factors in the industrial utilization of biomass, especially in the sustainable generation of cellulosic bioethanol. We report here a structural determination of an LPMO-oligosaccharide complex, yielding detailed insights into the mechanism of action of these enzymes. Using a combination of structure and electron paramagnetic resonance spectroscopy, we reveal the means by which LPMOs interact with saccharide substrates. We further uncover electronic and structural features of the enzyme active site, showing how LPMOs orchestrate the reaction of oxygen with polysaccharide chains.

[Ab] Resumo:Lentinula edodes-derived polysaccharides are well known for their immunomodulation and antitumor activities. However, the mechanisms of action have not been fully elucidated. This study presents proteomic analysis of the colon and small intestine from mice fed with an immunostimulating heteropolysaccharide L2 from the fruit body of L. edodes. Two-dimensional gel electrophoresis (2-DE) and MALDI-TOF-TOF MS/MS were employed to characterize the protein profiles. Twenty nine gel spots representing 20 proteins in colon tissues and 38 gel spots in small intestine tissues representing 23 proteins were identified as showing significant changes in abundance. These differential proteins in abundance are mainly involved in metabolism, binding, structural components, and response to stimulus. Protein-protein interaction network analysis demonstrated mapping of the 20 colon proteins to a 7-protein and a 3-protein sub-network, and mapping of the 23 small intestine proteins to a 9-protein and a 5-protein sub-network. All the 40 altered proteins were integrated into a unified network containing 25 proteins, suggesting the existence of a concerted mechanism, although acting on the colon and small intestine separately. These findings facilitate the understanding of the regulatory mechanism in response to L2 treatment.

[Ab] Resumo:BACKGROUND: Fermenting feed has gained a lot of popularity in recent years owing to its renowned benefits to the livestock and feed quality. In the current study, Lentinus squarrosulus mushroom mycelium was tested for its potential as a fermenting agent and source of natural antioxidant in the feed. RESULTS: Phenolic content of methanolic and hot water extracts of the mycelium culture and its fermented maize ranged from 94.01 to 386.59 mg gallic acid equivalents g(-1) extract while the DPPH radical scavenging, CUPRAC, reducing power (RPA) and ß-carotene bleaching (BCB) antioxidant activity had EC50 values ranged from 15.30 to 120.3, 0.74 to 4.71, 1.86 to 13.5 and 0.01 to 0.21 mg mL(-1) , respectively. At 1.0-20.0 mg mL(-1) , the extracts retarded 21.02-55.35% of lipid deterioration. Pearson correlation analysis revealed the phenolic content of the extracts has moderate correlation with DPPH (r = 0.589) and RPA (r = 0.580), also a high correlation with BCB antioxidant activity (r = 0.872). In principal component analysis, DPPH, CUPRAC and RPA were seen to be clustered tightly together while BCB antioxidant activity was grouped with the phenolic content. CONCLUSION: Overall, L. squarrosulus mycelium functioned as antioxidants via several mechanisms, involving either electron transfer or hydrogen transfer-based reactions suggesting it as a promising fermentation agent to enhance feed nutrition and the fermented maize as a valuable feed resource.

[Ab] Resumo:AIM: Lentinus squarrosulus is an edible wild mushroom commonly found in Asia. This species has several interesting features such as rapid mycelial growth, and hence has the potential to be used as food, functional food, and nutraceuticals. Our previous study shows that L. squarrosulus contains potent antioxidant compounds in vitro. This study aims to investigate the in vivo bioavailability of L. squarrosulus mycelium extract and its antioxidant effect on biomarkers of antioxidant defense and oxidative stress. METHODS: Water extract of mycelial biomass of L. squarrosulus was analyzed for in vivo antioxidant effects, including cupric-reducing antioxidant capacity (CUPRAC), glutathione peroxidase (GPx), xanthine oxidase (XO), advanced oxidation protein products (AOPPs), and lipid hydroperoxides (LHPs) at 0 and 28 days. GPx and XO were also analyzed in liver homogenates. Normal Sprague Dawley rats were treated with 250 and 500 mg/kg of extract for 28 days. RESULTS: The serum CUPRAC level increased after treatment with both concentrations, indicating that there was sufficient bioavailability of the extract which contributed to the total antioxidant capacity. GPx activity in both serum and liver was increased and this correlated with LHP level after treatment with 250 mg/kg of extract, but XO activity was significantly decreased after treatment with 500 mg/kg of the extract. Lack of difference between AOPP levels implied that there were no significant changes in oxidative damage of protein after treatment. CONCLUSION: This study clearly showed that L. squarrosulus mycelium antioxidant extract contains absorbable antioxidants that enter the circulating plasma and cause a significant acute increase in plasma antioxidant capacity. Thus, the water extract of L. squarrosulus mycelium, which can be obtained abundantly by liquid fermentation, may serve as an antioxidant ingredient in functional foods and nutraceuticals.

[Ab] Resumo:The addition of an antioxidant (2-ethyl-6-methyl-3-hydroxypyridine hydrochloride) to a culture of the fungus Lentinus tigrinus growing on a medium with lignosulfonate inhibited growth and changed the composition of cell phospholipids. The ratio of lipid messengers also changed, the phosphatidic acid level decreased, and the content of phosphatidylinositol dramatically increased. The substitution of lignosulfonate with glucose and the addition of an antioxidant increased the biomass yield of L. tigrinus, as well as that of another fungus, Cunninghamella japonica, which was incapable of biodegrading the biopolymer. The obtained results indicate the specificity of growth processes in the presence of lignosulfonate and confirm the role of free radical oxidation reactions in the biodegradation of this biopolymer by L. tigrinus.

[Ab] Resumo:Species of mushroom genus Lentinus (=Lentinula) are best known for the commercially important and extensively studied culinary-medicinal shiitake, L. edodes. A few mycelium growth studies have focused on Lentinus boryana, but information is lacking for L. raphanica and L. aciculospora, endemic to the Americas. In this study, 14 dikaryon strains representing 5 Lentinus species were grown on 5 nutritive agar media at increments of 5°C. Growth for each species was significantly slower on corn meal agar, but no differences were found among malt extract, potato dextrose, malt peptone, and yeast malt extract agars. Lentinus aciculospora and L. boryana consistently exhibited the slowest mycelium growth rates among all species and across all temperatures tested, with optima at 15°C and 20°C. The fastest mycelium growth rates for L. edodes, L. novaezelandiae, and L. raphanica occurred at 25°C. Strains of the latter continued to grow well at 30°C, whereas growth of the other 2 species declined significantly. Differences in mycelium growth rates for American strains could be partially explained by their geographic locations, indicating that understanding this physiological parameter has important ramifications for the edible mushroom industry.
