[PMID: 38925407 DOI: 10.1016/j.biortech.2024.131037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/04/2024] [Revised: 06/11/2024] [Accepted: 06/23/2024] [Indexed: 06/28/2024]
Abstract
White rot fungi are promising organisms for the production of mycelial-based biofoams, providing a sustainable means of valorizing lignocellulosic wastes. This study explores the utilization of two indigenous fungal species, isolated from Argentina and belonging to the genera Trametes, for producing biofoams from brewery waste. The resulting biofoams exhibited an average density of 0.30 g cm-3, a Young's modulus of approximately 1 MPa, and a compressive stress of around 19 MPa. Additionally, the variation of laccase activity throughout the biofoam production process was evaluated. Surprisingly, residual laccase activity was detected in the biofoams following oven drying at temperatures of 60, 80, and 100 °C. This detection highlights the untapped enzymatic potential of the biofoams and positions them as promising green catalysts for various biotechnological applications.

Barido FH, Jang A, Pak JI, Kim YJ, Lee SK. The Effect of Pre-Treated Black Garlic Extracts on the Antioxidative Status and Quality Characteristics of Korean Ginseng Chicken Soup (Samgyetang). Food Sci Anim Resour 2021; 41:1036-1048. [PMID: 34796329 PMCID: PMC8564326 DOI: 10.5851/kosfa.2021.e54] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2021] [Revised: 09/10/2021] [Accepted: 09/13/2021] [Indexed: 11/29/2022] Open
Abstract
This study investigated the possible improvement in the antioxidative status and
quality characteristics of ready-to-eat (RTE) Samgyetang after adding various
black garlic (BG) extracts. The antioxidant activity, total phenolic content
(TPC), total flavonoid content (TFC), meat quality indexes, and lipid oxidation
rates were measured after receiving one of five different treatments consisting
of conventional Samgyetang broth as a negative control, raw garlic (RG) extract
as a positive control, BG, oven-dried BG, and maltodextrin-encapsulated BG
extract as treatments. Employing retort cooking, fat trimmed carcasses were
added to the initially prepared broth together with a phenolic extract that was
set at 5% (w/w). A significant intensification of red and yellow color
was observed in breast and thigh meat treated with BG extracts, regardless of
pretreatment, compared to the negative control and RG. The moisture percentage
was affected by the addition of BG extracts, where the encapsulation group
retained the highest water content after retorting. In terms of antioxidative
status, maltodextrin-encapsulated BG extract was as effective as an oven-dried
extract to scavenge free radicals and showed the highest score among samples
(p<0.01). The concentration of TFC was found to be the highest and did
not differ between encapsulation and oven-dried groups, followed by BG, RG, and
the negative control. However, the addition of encapsulated BG extract was the
most effective in delaying the formation of malondialdehyde among the samples.
Therefore, pre-treatment of BG extract through encapsulation is recommended to
develop a higher antioxidative status and quality characteristics of
Samgyetang.

Increased Extracellular Saponin Production after the Addition of Rutin in Truffle Liquid Fermentation and Its Antioxidant Activities. FERMENTATION 2021.

Abstract
Saponins possess a variety of pharmacological effects and exhibit great potential in the food industry as bioactive substances. In this study, extracellular saponin production via the liquid fermentation of Tuber melanosporum occurred with the addition of rutin. For this purpose, medium composition and culture conditions were optimized using single-factor experiments and an orthogonal experiment design. The optimal medium consisted of glucose (43.5 g/L), peptone (6 g/L), KH2PO4 (1.15 g/L), NaCl (0.2 g/L), vitamin B2 (0.082 g/L), vitamin B6 (0.1 g/L), vitamin C (0.02 g/L), and rutin (4.8 g/L). The culture conditions were as follows: 12.5% (v/v) inoculation, medium volume of 50 mL/250 mL flask, culture temperature of 24 °C, shaker speed of 190 rpm, initial pH of 5.7, and culture time of 96 h. Finally, a maximal extracellular saponin content of 0.413 g/L was obtained, which was 134.7% higher than that in the base medium. Rutin proved to be an excellent promoter, because the saponin production was increased by 50.2% compared to that in the optimized medium without rutin. The 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging activity, hydroxyl radical scavenging activity, and ferric reducing antioxidant power of truffle saponins reached 94.13%, 79.26%, and 42.22 mM, respectively. This study provides a useful strategy for fungal bioactive saponin production by liquid fermentation with the addition of flavonoid compounds.

A new record of Ganodermatropicum (Basidiomycota, Polyporales) for Thailand and first assessment of optimum conditions for mycelia production. MycoKeys 2019; 51:65-83. [PMID: 31130813 PMCID: PMC6517369 DOI: 10.3897/mycokeys.51.33513] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2019] [Accepted: 03/12/2019] [Indexed: 11/27/2022] Open
Abstract
In this study a new record of Ganodermatropicum is described as from Chiang Rai Province, Thailand. The fruiting body was collected on the base of a living Dipterocarpus tree. The sample is described on the basis of morphological characteristics and phylogenetic analyses, and compared with closely related taxa. Multigene phylogenetic analyses of LSU, ITS, and RPB2 highly support the placement of the G.tropicum group with isolates from China and Taiwan (Maximum likelihood 100%, Maximum parsimony 100%, and Bayesian posterior probabilities 1.00). The optimal media, pH, and temperature for mycelial growth of the G.tropicum strain KUMCC18-0046 was also investigated and is reported as: PDA, MEA, and YPD, at pH 7–8 and 25–28 °C, respectively. This is the first report on the successful growing conditions for mycelial production, but unfortunately fruiting could not be achieved.
