Abstract
The purpose of this study was to investigate structural, functional and antioxidant properties of Lentinus edodes protein hydrolysates (LEPHs) by alcalase, protamex, trypsin, papain and neutrase. Structural and functional properties were determined using gel electrophoresis, Fourier transform infrared spectroscopy, laser scattering, fluorescence spectroscopy, emulsifying properties etc. Antioxidant activities were detected by Fe2+ chelating, hydroxyl and DPPH radical scavenging assays. Enzymatic hydrolysis destroyed secondary and tertiary structures of Lentinus edodes protein, decreased its molecular weight and particle size, particularly hydrolysate prepared by alcalase with the highest hydrolytic degree (32.86 ± 0.98 %), the smallest particle (130.77 ± 1.85 nm) and molecular weight (5.86 kDa). Moreover, alcalase hydrolysate exhibited the highest emulsifying stability, the strongest hydroxyl radical scavenging activity and Fe2+ chelating ability among LEPHs. Whilst trypsin hydrolysate displayed the highest DPPH radical scavenging, foaming and fat absorption capacity. These results provided basis for LEPH as ingredients to be used for food industry.

Exploring the Bioactive Potential of Calostoma insigne, an Endangered Culinary Puffball Mushroom, from Northeastern Thailand. Foods 2023; 13:113. [PMID: 38201139 PMCID: PMC10778563 DOI: 10.3390/foods13010113] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2023] [Revised: 12/25/2023] [Accepted: 12/27/2023] [Indexed: 01/12/2024] Open
Abstract
Calostoma insigne puffball mushrooms are only found in forests with rich biodiversity in very few countries including Thailand, and their biofunctions remain largely unexplored. This study used the agar disk diffusion assay, the anti-glucosidase assay, and the 3, 4, 5-dimethylthiazol-2-yl-2-5-diphenyltetrazolium bromide (MTT) assay to evaluate the bioactive potential of these endangered puffball mushrooms. Internal transcribed spacer (ITS) gene analysis identified C. insigne, a puffball mushroom with green, globose, and spiny spores. Fourier-transform infrared spectroscopy (FTIR) analysis confirmed the polysaccharide structure while scanning electron microscopy (SEM) revealed a fiber-like network. The ethanolic gelatinous fruiting body extract exhibited 1,1-diphenyl-2-picrylhydrazyl (DPPH)-scavenging capacity (57.96%), a ferric ion-reducing antioxidant power (FRAP) value of 1.73 mg FeSO4/g, and α-glucosidase inhibition (73.18%). C. insigne cytotoxicity was effective towards HT-29 colon cancer cells using the MTT assay (IC50 of 770.6 µg/mL at 72 h) and also showed antiproliferative capacity (IC50 of 297.1 µg/mL). This puffball mushroom stimulated apoptotic genes and proteins (caspase-3, Bax, and p21) via an intrinsic apoptotic pathway in HT-29 cells. In the laboratory, the medium formula consisting of 20% potato, 2% sucrose, and 0.2% peptone was optimal to increase fungal mycelial biomass (2.74 g DW/100 mL), with propagation at pH 5.0 and 30 °C. Puffball mushrooms are consumed as local foods and also confer several potential health benefits, making them worthy of conservation for sustainable utilization.

Int J Biol Macromol 2023; 230:123207. [PMID: 36632960 DOI: 10.1016/j.ijbiomac.2023.123207] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2022] [Revised: 01/04/2023] [Accepted: 01/05/2023] [Indexed: 01/10/2023]
Abstract
The Cordyceps militaris gene CCM_03832 encodes a ricin-B like lectin. The gene was cloned and expressed in Escherichia coli, and its protein product, named CMRBL (C. militaris ricin-B like lectin), was purified by galactose affinity chromatography. Of nine different sources of erythrocytes, CMRBL showed only specific hemagglutinating activity against rat and rabbit erythrocytes with titers of 22 and 28, respectively. Glycan array analyses by the Consortium for Functional Glycomics showed that CMRBL possesses very high specific binding activity of glycans terminated with type II LacNAc (non-reducing Galβ1-4GlcNAc). Compared with other well-known Gal-terminated binding lectins such as Erythrina cristagalli agglutinin, Ricinus communis agglutinin, and Jacalin, CMRBL showed better binding specificity to type II LacNAc compared the other lectins. CMRBL showed lowest binding activity to ZR-75-30 and MDA-MB-468 cell lines among five tested cell lines (H22, THP-1, MDA-MB-231, ZR-75-30, and MDA-MB-468 cells). Transfection of type II LacNAc main galactosyltransferase B4GALT3 to ZR-75-30 significantly improved CMRBL binding activity compared with control. CMRBL was also applied for testing the type II LacNAc modification of Etanercept successfully. Our data suggest that CMRBL would be a useful tool to recognize type II LacNAc, especially distinguish type II from other galactose-terminated glycans in glycan biology research.

Abstract
Edible mushrooms are widely appreciated for their appealing flavours, low caloric values and high content of presumably health-protecting metabolites. Their long history of safe use together with the looming worldwide food crisis have revived the idea of generating meat analogues and protein isolates by the controlled fermentation of mycelia of these edible fungi as a dietary option. The occurrence of proteins, polysaccharides, smaller metabolites, metal ions and toxins in mycelia and fruiting bodies is compared among the three most popular species, Agaricus bisporus (button mushroom), Pleurotus ostreatus (oyster mushroom), Lentinus edodes (shiitake) and some closely related species. Large effects of substrate chemistry, strain, developmental stage and ecological interactions result in a wide variation of the concentrations of some metabolites in both mycelial cells and fruiting bodies. This is obviously a result of the high adaptation abilities required to survive in natural habitats. Fungal bioprocesses are decoupled from agricultural production and can be operated anytime, anywhere, and on any scale according to demand. It is concluded that fungal biomass, if produced under food-grade conditions and on an industrial scale, could provide a safe and nutritious meat substitute and protein isolates with a high biological value for future vegan foods.
