However, understanding the criteria used for traditional nomenclature of fungi, particularly wild edible mushrooms across linguistic groups, remains limited, leading to frequent errors in species recognition. This study seeks to assess how linguistic affiliations influence the local naming of useful wild mushrooms, and is the first of its kind in Benin. In order to understand how local people recognize, classify and name mushrooms that develop in or close to their villages, 2234 respondents from five socio-linguistic groups across three geographical areas were interviewed. Structured and semi-structured interviews were conducted to gather data on the local naming criteria for edible wild mushrooms. Citation scores were recorded for both nomenclature criteria and species, considering variables such as linguistic groups, age, and language. Twenty-two nomenclature criteria were used by local people to name edible wild species. Strong similarity in classification and naming of species was shown in 97% of the languages, while 3% showed differing classification criteria. The Gur, Atlantic, and Mande linguistic groups demonstrated more comprehensive traditional taxonomic and nomenclatural knowledge, sharing six common criteria: texture, taste, size, kingdom (Fungi), form, and substrate. Overall, local populations possess extensive knowledge regarding the diversity of wild edible mushrooms in their environment.展开更多

A significant proportion of the studies focus on medicinal plants, in contrast to those that examine food products. Nevertheless, studies on edible wild mushrooms as NTFPs and cultivated mushrooms, on their economic potential and value chains in the Great Lakes Region, remain scarce and largely absent for some NTFPs. In light of the aforementioned considerations, the present study aims to examine the economic potential and value chain of the production sector of wild edible mushrooms (WEM) and cultivated mushrooms (CM) within the Virunga National Park (PNVi) and its surrounding areas in North Kivu, Democratic Republic of the Congo (DRC). To this end, a sample of 432 respondents was selected, distributed equitably among the actors of the Goma-Kitshanga-Mweso value chain, the Goma-Rutshuru chain, the Beni-Mutwanga chain, and the Beni-Mangina chain. A digital questionnaire consisting of open and closed questions was administered, and observations were carried out concurrently. The quantities of mushrooms sold were weighed and photographed. The results demonstrated that, when the eight-month fruiting period of wild and cultivated mushrooms was considered as a single year for all actors within the value chain, a picker could sell 6.1 kg at $2 and earn $12. A seller could sell 16 kg at $4 and earn $64, while a grower could sell 502 kg at $3 and earn $1506. Consequently, the CM grower generates a significantly higher profit than other participants in the value chain, despite the expenses he incurs. Ultimately, the domestication of WEM, highly prized by the local population of the Virunga National Park, has the potential to enhance their household incomes, as evidenced by the findings of this study.展开更多

The catalyst of sodium salt of tungstic acid with Co as central atom （Na5CoW12O40） showed optimum activity towards transesterification compared with other heteropoly tungstates. The catalysts activities were correlated with the observed physico-chemical characteristics derived from FT-infrared （FT-IR）, X-ray diffraction （XRD）, temperature-programmed desorption of ammonia （NH3-TPD） and carbon dioxide （CO2-TPD）. The Na5CoW12O40 catalyst exhibiting high activity even at 65 ℃ is due to the presence of strong acidic as well as basic sites. The disclosed catalyst is tolerable towards water and free fatty acids present in the oils. The influence of catalyst loading, reaction time and reaction temperature is studied to optimize the reaction parameters.展开更多

文摘Edible bird's nest(EBN),abundant in sialic acid(SA)has been recognized as a natural substance beneficial to brain development and cognitive ability.In order to investigate active component of EBN,sialylated glycopeptides(SCP)were extracted from EBN by 60%ethanol after trypsin hydrolysis and its effects on central nervous system was evaluated in lipopolysaccharide(LPS)-induced neuroinflammation mice.EBN,SCP,and SA pretreatment and intervention reduced interleukin-1β(IL-1β),tumor necrosis factor-α(TNF-α),and interleukin-6(IL-6)levels in hippocampus and cortex,meanwhile inhibited the activation of microglia,astrogliosis and neuron apoptosis,which were consistent with the learning and memory improvement and anti-depression effects in behavioral tests.The counts of leukocytes,neutrophils and monocytes,as well as IL-1β,TNF-α,and IL-6 levels in peripheral circulation were significantly reduced by SCP.Results of plasma metabolomics suggested SCP up-regulated energy metabolism,promoted the recovery of primary and secondary bile acid metabolism and indole metabolism,where microbiota may involve.16S rDNA sequencing of colonic contents showed EBN,SCP and SA repaired dysbacteriosis in LPS-treated mice by significantly up-regulating the anti-inflammatory Muribaculaceae and inhibiting pro-inflammatory related Desulfovibrio and Candidatus_Saccharimonas.In addition,both EBN and SCP could significantly enrich Aerococcus,while SA could specifically enrich Prevotellaceae_UCG_001.The gut-brain axis was preliminarily established,and SCP may have the potential to be a functional factor for neuroprotection applied in EBN industry.
文摘The increasing incidence of neurodegenerative diseases(NDs)and the constraints of existing treatment methods have spurred a keen interest in investigating alternative therapies.Medicinal plants,renowned for their long-standing use in traditional medicine,offer a hopeful avenue for discovering new neuroprotective agents.This study emphasizes the potential neuroprotective characteristics of edible fruit plants in Bangladesh,specifically focusing on their traditional folk medicine uses for neurological disorders.This study provides an in-depth overview of the different types of edible fruit trees in Bangladesh and their phytochemicals,including flavonoids,terpenoids,and phenolic acids.This work examines the scientific data supporting the neuroprotective properties of bioactive chemicals from plants.It further explores the mechanisms by which these compounds work to counteract oxidative stress,decrease inflammation,and stimulate neurogenesis.Moreover,the study investigates toxicological characteristics and bioactive components of some fruits,emphasizing the importance of further investigation to measure their safety profile comprehensively.This thorough study highlights the potential benefits of Bangladesh's edible fruit trees as a rich source of neuroprotective chemicals.It also shows that additional research might lead to novel approaches for improving brain functioning and preventing NDs.
文摘A substantial body of research has been conducted with the objective of enhancing the understanding of Non-Timber Forest Products (NTFP) in Central Africa. A significant proportion of the studies focus on medicinal plants, in contrast to those that examine food products. Nevertheless, studies on edible wild mushrooms as NTFPs and cultivated mushrooms, on their economic potential and value chains in the Great Lakes Region, remain scarce and largely absent for some NTFPs. In light of the aforementioned considerations, the present study aims to examine the economic potential and value chain of the production sector of wild edible mushrooms (WEM) and cultivated mushrooms (CM) within the Virunga National Park (PNVi) and its surrounding areas in North Kivu, Democratic Republic of the Congo (DRC). To this end, a sample of 432 respondents was selected, distributed equitably among the actors of the Goma-Kitshanga-Mweso value chain, the Goma-Rutshuru chain, the Beni-Mutwanga chain, and the Beni-Mangina chain. A digital questionnaire consisting of open and closed questions was administered, and observations were carried out concurrently. The quantities of mushrooms sold were weighed and photographed. The results demonstrated that, when the eight-month fruiting period of wild and cultivated mushrooms was considered as a single year for all actors within the value chain, a picker could sell 6.1 kg at $2 and earn $12. A seller could sell 16 kg at $4 and earn $64, while a grower could sell 502 kg at $3 and earn $1506. Consequently, the CM grower generates a significantly higher profit than other participants in the value chain, despite the expenses he incurs. Ultimately, the domestication of WEM, highly prized by the local population of the Virunga National Park, has the potential to enhance their household incomes, as evidenced by the findings of this study.

文摘Alkali salts of tungsten based heteropoly acids with different central atom such as P, Si and Co were prepared and evaluated for transes- terification of both edible and non-edible oils to their corresponding fatty acid methyl esters. The catalyst of sodium salt of tungstic acid with Co as central atom （Na5CoW12O40） showed optimum activity towards transesterification compared with other heteropoly tungstates. The catalysts activities were correlated with the observed physico-chemical characteristics derived from FT-infrared （FT-IR）, X-ray diffraction （XRD）, temperature-programmed desorption of ammonia （NH3-TPD） and carbon dioxide （CO2-TPD）. The Na5CoW12O40 catalyst exhibiting high activity even at 65 ℃ is due to the presence of strong acidic as well as basic sites. The disclosed catalyst is tolerable towards water and free fatty acids present in the oils. The influence of catalyst loading, reaction time and reaction temperature is studied to optimize the reaction parameters.
