Russula lakhanpalii is a wild edible mushroom, collected from Pedkhal block of Pauri Garhwal, India. The nutritional composition, antioxidant activity (AOA), and antibacterial activity (ABA) of R. lakhanpalii were analyzed for the first time in this study. Dried fruiting bodies of R. lakhanpalii were reported to contain 17.7% ash, 10% crude fiber, 13.4% protein, 30.9% carbohydrate, and 5% unsaturated lipids. In addition, 10.22-72.56% DPPH scavenging activity also confirmed the good antioxidant nature of R. lakhanpalii. The methanolic extract of R. lakhanpalii fruiting bodies inhibited the growth of five pathogenic bacteria in vitro; Klebsiella pneumoniae (MTCC 4030), Micrococcus luteus (MTCC 1809), Staphylococcus aureus (MTCC 1144), Escherichia coli (MTCC 68), and Streptococcus pneumoniae (MTCC 655). The maximum and minimum zone of inhibitions (ZOIs) reported were 17.8 ± 1.04 mm (K. pneumoniae) and 11.16 ± 0.76 mm, (E. coli), respectively. The noticeable feature of the extract was the inhibition of erythromycin-resistant E. coli and M. luteus by it, which were resistant to 15 μg/disc concentration of erythromycin. Dietary components, antibacterial and antioxidant potentials of R. lakhanpalii suggested its nutraceutical and medicinal applications.

Russula lakhanpalii是一种野生食用蘑菇,采自印度保里加尔瓦尔的佩德哈尔街区。本研究首次对枇杷的营养成分、抗氧化活性(AOA)和抗菌活性(ABA)进行了分析。据报道,干子实体的灰分含量为17.7%,粗纤维含量为10%,蛋白质含量为13.4%,碳水化合物含量为30.9%,不饱和脂肪含量为5%。此外,10.22-72.56%的DPPH清除率也证实了白杨具有良好的抗氧化性。木参子实体甲醇提取物对5种病原菌的体外生长有抑制作用;肺炎克雷伯菌(MTCC 4030)、黄体微球菌(MTCC 1809)、金黄色葡萄球菌(MTCC 1144)、大肠杆菌(MTCC 68)和肺炎链球菌(MTCC 655)。报道的最大和最小抑制区(ZOIs)分别为肺炎克雷伯菌(17.8±1.04 mm)和大肠杆菌(11.16±0.76 mm)。其显著特点是对红霉素耐药大肠杆菌和黄体分枝杆菌有抑制作用,对15 μg/盘浓度的红霉素均有耐药性。其膳食成分、抗菌活性和抗氧化活性表明其具有一定的营养和药用价值。

The present study was an attempt to evaluate the antimicrobial and anthelmintic potential of two Amanita species, i.e., A. orsonii and A. glarea, along with their qualitative mycochemical screening. Maceration technique was adopted to make crude extracts in non-polar (petroleum ether and chloroform) and polar (ethanol and distilled water) solvents. Qualitative mycochemical screening revealed the presence of a variety of secondary metabolites like terpenoids, flavonoids, tannins, alkaloids, saponins, and cardiac glycosides. Antimicrobial activities were carried out by using agar well diffusing method against four bacterial and one fungal strain. The antibacterial potential ranged between 4.86 ± 0.088 mm and 34.83 ± 0.166 mm with maximum inhibition zone exhibited by petroleum ether extract against Pseudomonas fluorescens and least potential by distilled water macerate of A. orsonii against the Escherichia coli. The antifungal activity ranged between 14.5 ± 0.288 and 24.76 ± 0.145 mm, with the highest potential provided by chloroform extract of A. orsonii and least capability put forward by A. glarea by petroleum ether extract against Fusarium solanii. Antibiotics and antimycotic discs were used as standard and some of the crude extracts showed bigger zone of inhibition as compared to standard. Different concentrations of ethanolic extracts of both mushrooms were subjected to anthelmintic potential against parasite Haemonchus contortus. All the crude extracts were more potent than standard oxfandazole used. Anthelmintic potential ranged between 9.9 ± 0.057 and 54.93 ± 0.033 minutes for death of parasite, while the paralyzed time ranged between 4.86 ± 0.088 and 24.86 ± 0.088 minutes. From the results obtained it was concluded that both mushrooms can be used as potential source of curative antibacterial, antifungal, and anthelmintic agents against several diseases that might be used in pharmaceutical industries for making medicines and to screen out secondary metabolites in future.

本研究旨在评价两种金刚鹦鹉的抗菌和驱虫潜力,即A. orsonii和A. glarea,并进行定性的真菌化学筛选。采用浸渍法在非极性溶剂(石油醚和氯仿)和极性溶剂(乙醇和蒸馏水)中制备粗提物。定性的真菌化学筛选显示存在多种次生代谢物,如萜类、黄酮类、单宁、生物碱、皂苷和心苷。采用琼脂孔扩散法对4株细菌和1株真菌进行抑菌试验。石油醚提取物对荧光假单胞菌的抑菌作用范围为4.86±0.088 mm ~ 34.83±0.166 mm,其中石油醚提取物对荧光假单胞菌的抑菌作用最大,而奥氏单胞菌浸渍蒸馏水对大肠杆菌的抑菌作用最小。对茄枯病菌的抑菌活性范围为14.5±0.288 ~ 24.76±0.145 mm,其中三氯甲烷提取物对茄枯病菌的抑菌活性最高,石油醚提取物对茄枯病菌的抑菌活性最低。以抗菌素和抗真菌片为对照品,部分粗提物的抑菌范围较对照品大。两种蘑菇不同浓度的乙醇提取物对弓形血螨的驱虫潜力进行了研究。所有粗提物均比标准奥克斯达唑有效。虫虫死亡电位范围为9.9±0.057 ~ 54.93±0.033 min,瘫痪时间范围为4.86±0.088 ~ 24.86±0.088 min。由此得出结论,这两种蘑菇都可以作为治疗性抗菌、抗真菌和驱虫药的潜在来源,用于制药工业生产药物和筛选次生代谢物。

Pleurotus citrinopileatus, also known as golden oyster mushroom, is a newly industrialized edible mushroom mainly distributed in East Asia. It is a kind of saprophytic edible fungus with strong degradation characteristics, commonly found on fallen trees and stumps of broad-leaf tree species. So far, abundant kinds of bioactive compounds such as polysaccharides, ergothioneine, sesquiterpenes, and glycoprotein have been isolated from P. citrinopileatus and studied. Studies have confirmed that these compounds are beneficial to human health. In this paper, the recent studies on the cultivation, degradation characteristics application, and health effects of P. citrinopileatus are reviewed, and their development trends are discussed.

Strain aging has been mainly contributing to the "uncertainty" of Morchella farming. The situation calls for urgent quantitative assessment of strain aging in cultivated Morchella mushrooms. In this paper, systemic senescence of the productive strains of M. eximia, M. importuna, and M. sextelata was achieved through successive subculturing to provide subcultures with different degree of aging for further studies. Then the quantitative assessment of morel strain aging was conducted by activity assay of amylase and xylanase using dinitrosalicylic acid (DNS) method. The results suggested that both activity of amylase and xylanase decreased along with the rise of subculture times. Meanwhile, the correlation between xylanase activity and time of subculturing in the tested morel strains was higher than that of amylase assay. Consequently, assay of amylase and xylanase activity by DNS method can be used in the quantitative assessment of morel strain aging, and assay of xylanase activity is the better alternative. The work will improve the settlement of "uncertainty" in the morel industry and thus be beneficial for stable development of morel farming.

菌种老化是羊肚菌养殖“不确定性”的主要原因。这种情况迫切需要对栽培羊肚菌菌种老化进行定量评估。本文通过连续继代培养,实现了产菌eximia、M. importuna和M. sextelata的系统性衰老,为进一步研究提供了不同程度衰老的继代培养。采用二硝基水杨酸(DNS)法测定淀粉酶和木聚糖酶活性,定量评价菌株老化情况。结果表明,随着继代次数的增加,淀粉酶和木聚糖酶活性均呈下降趋势。同时,木聚糖酶活性与继代时间的相关性高于淀粉酶试验。因此,用DNS法测定淀粉酶和木聚糖酶活性可用于霉菌菌株老化的定量评价,而测定木聚糖酶活性是较好的替代方法。这项工作将有助于解决羊肚菌产业中的“不确定性”,从而有利于羊肚菌养殖的稳定发展。

To investigate the differences between Korean Ganoderma lucidum spore powder (KP), broken-spo-roderm KP (BSKP), Chinese traditional G. lucidum spore powder (CP), and broken-sporoderm CP (BSCP), they were identified by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), second derivative infrared spectroscopy (SD-IR), dual-index sequence analysis (DISA) and X-ray diffraction (XRD). SEM showed that there were no significant differences in microstructure between the two kinds of spore powders. FT-IR spectra showed that the four spore powders appeared with characteristic peaks of 3400, 3006, 2925, 1745, 1535, 1454, 1249, 1074, 1049, and 896 cm-1, respectively, they were contained the characteristic peaks of total triterpenes, polysaccharides and fatty acids. DISA showed that the same species of spore powders, the overall similarity of before and broken the sporoderm was high with minor differences and there were no differences between the different kinds of spore powders. Similarity analysis showed that the four spore powders were in high agreement and were no differences. The polysaccharide, total triterpene, spore oil and protein content of the four spore powders were determined separately. The results showed that the active ingredients content of the batch of KP were lower than that of CP, that of BSKP were lower than that of BSCP, while the active ingredients content of both broken-sporoderm spore powders were higher than that of before broken-sporoderm. It is inferred that the structure of the main chemical and component of KP is the same as that of CP. This study provides a reference for the future development and application of G. lucidum.

为了研究韩国灵芝孢子粉(KP)、破孢子皮孢子粉(BSKP)、中国传统灵芝孢子粉(CP)和破孢子皮孢子粉(BSCP)的区别,采用扫描电镜(SEM)、傅里叶变换红外光谱(FT-IR)、二阶导数红外光谱(SD-IR)、双指数序列分析(DISA)和x射线衍射(XRD)对其进行了鉴定。SEM结果表明,两种孢子粉的微观结构无显著差异。FT-IR光谱显示,4种孢粉的特征峰分别为3400、3006、2925、1745、1535、1454、1249、1074、1049和896 cm-1,含有总三萜、多糖和脂肪酸的特征峰。DISA结果表明,同一种孢子粉,孢子粉粉碎前和粉碎后孢子粉的整体相似性较高,差异较小,不同种类孢子粉之间没有差异。相似度分析表明,4种孢粉具有较高的一致性,无差异。分别测定四种孢子粉的多糖、总三萜、孢子油和蛋白质含量。结果表明:KP的有效成分含量低于CP, BSKP的有效成分含量低于BSCP,而破孢子粉和破孢子粉的有效成分含量均高于破孢子粉。推测KP的主要化学成分结构与CP相同,本研究为今后灵芝的开发应用提供了参考。

Prebiotics have gained much attention in recent years as functional food ingredients. This has encouraged researchers to look for sustainable alternative sources of prebiotics. Prebiotics help in the modulation of the human intestinal microbiota and thereby improve host health. Chicory, asparagus, and Jerusalem artichoke are some conventional prebiotics that have been extensively studied. Mushrooms are rich sources of medicinal foods as well as bioactive polysaccharides and essential amino acids. They contain large amounts of chitin, mannans, galactans, xylans, glucans, krestin, lentinan, and hemicellulose, thus making it a potential candidate for prebiotics. They are also rich sources of fibers, proteins, and antioxidants. Several mushroom species like Ganoderma lucidum, Pleurotus ostreatus, Hericium erinaceus, Agaricus bisporus, and Lentinula edodes are rich in medicinal properties that have an array of applications. These medicinal mushrooms can be repurposed to regulate gut microbiota. In this review, we discuss the prebiotic effects of different mushroom species on probiotic organisms. We also reviewed the potential of mushroom waste as novel, cheap, and alternative sources of prebiotics.

益生元作为功能性食品原料近年来受到广泛关注。这促使研究人员寻找可持续的益生元替代来源。益生元有助于调节人类肠道微生物群,从而改善宿主健康。菊苣、芦笋和菊芋是一些被广泛研究的传统益生元。蘑菇是药用食品以及生物活性多糖和必需氨基酸的丰富来源。它们含有大量的几丁质、甘露聚糖、半乳糖、木聚糖、葡聚糖、蓖麻素、香菇多糖和半纤维素,因此它是益生元的潜在候选者。它们也是纤维、蛋白质和抗氧化剂的丰富来源。一些蘑菇种类,如灵芝、平菇、猴头菇、双孢蘑菇和香菇,具有丰富的药用特性,具有一系列的应用。这些药用蘑菇可以用来调节肠道菌群。本文综述了不同菌种对益生菌的益生元作用。我们还回顾了蘑菇废料作为新型、廉价和替代益生元来源的潜力。

Honey mushroom, Armillaria mellea, is an edible and medicinal lignicolous basidiomycete. In this study, we investigated the chemical composition and bioactive properties of its methanolic and acetonic extracts. The chemical characterization of extracts was done with the HPLC-DAD-MS/MS method. The results showed that potassium was the most abundant mineral; chlorogenic acid was the most abundant polyphenol; malic acid was the most abundant organic acid; and among carbohydrates, the most abundant were sorbitol, glucose, fructose, and saccharose. Antioxidative activity was assessed by DPPH (IC50 of the methanolic extract was 608.32 μg/mL and of the acetonic extract 595.71 μg/mL) and reducing power assays (the results ranged between 0.034 and 0.102 μg/mL). Total phenolic content was determined as gallic acid equivalent (methanolic extract: 4.74 mg GAE/g; acetonic extract: 5.68 mg GAE/g). The microdilution assay was used to evaluate the antimicrobial activity of the extracts, and the results ranged from 1.25 to 20 mg/mL. The antidiabetic effect of the extracts was tested by the α-amylase (the results ranged from 34.90% to 41.98%) and α-glucosidase assays (the results were in the range of 0.55-2.79%). The neuroprotective activity was explored by the acetylcholinesterase inhibition assay (the results were in the range of 1.94-7.76%). The microtetrazolium assay was used to investigate the cytotoxic activity of the extracts (the IC50 values ranged from 212.06 to > 400 μg/mL). Although some results suggest that some activities of the extracts are relatively moderate, the honey mushroom can still be considered an excellent source of food and bioactive compounds with medicinal value.

蜜环菌(蜜环菌)是一种可食用和药用的木质素担子菌。在本研究中,我们研究了其甲醇和丙酮提取物的化学成分和生物活性。采用HPLC-DAD-MS/MS法对提取物进行化学表征。结果表明,钾是最丰富的矿物质;绿原酸是含量最高的多酚;苹果酸是最丰富的有机酸;在碳水化合物中,含量最多的是山梨醇、葡萄糖、果糖和蔗糖。通过DPPH(甲醇提取物IC50为608.32 μg/mL,丙酮提取物IC50为595.71 μg/mL)和还原力(0.034 ~ 0.102 μg/mL)测定其抗氧化活性。总酚含量以没食子酸当量(甲醇提取物:4.74 mg GAE/g;丙酮提取物:5.68 mg GAE/g)。采用微量稀释法评价提取物的抑菌活性,结果范围为1.25 ~ 20 mg/mL。采用α-淀粉酶(34.90% ~ 41.98%)和α-葡萄糖苷酶(0.55 ~ 2.79%)测定其抗糖尿病作用。通过乙酰胆碱酯酶抑制试验探讨其神经保护活性(结果在1.94 ~ 7.76%范围内)。采用微量四氮唑法测定提取物的细胞毒活性(IC50值为212.06 ~ > 400 μg/mL)。虽然一些研究结果表明,蜜菇提取物的一些活性相对中等,但蜜菇仍然可以被认为是具有药用价值的食物和生物活性化合物的极好来源。

The asexual form of Ophiocordyceps sinensis has been controversial, but various morphologic mycelium appeared when O. sinensis was cultured under experimental conditions. To explore the generation mechanism of morphologic mycelium, developmental transcriptomes were analyzed from three kinds of mycelium (aerial mycelium, hyphae knot, and substrate mycelium). The results showed that diameter and morphology of these three kinds of mycelium were obviously different. KEGG functional enrichment analysis showed that the differential expressed genes (DEGs) of substrate mycelium were enriched in ribosomes and peroxisomes, indicating that prophase culture was rich in nutrients and the metabolism of substrate mycelium cells was vigorous in the stage of nutrient absorption. The up-DEGs of hyphae knot were mainly enriched in the oxidative phosphorylation pathway, indicating that oxidative phosphorylation was the main energy source for mycelium formation in the stage of nutrient accumulation and reproductive transformation. The up-DEGs of aerial mycelium were mainly enriched in the synthesis and degradation pathways of valine, leucine, and isoleucine, suggesting that the occurrence of aerial mycelium was related to amino acid metabolism at the later stage of culture, and nutritional stress accelerated the reproduction of asexual spores. In addition, the important roles of mycelium formation related genes were verified by combined analysis of qRT-PCR and transcriptome sequencing. Collectively, this study will provide theoretical guidance for inhibiting the occurrence of aerogenous mycelium and promoting the development of mycelium into pinhead primordia in the culture of O. sinensis in the future.

关于冬虫夏草的无性形态一直存在争议,但在实验条件下,冬虫夏草出现了多种形态的菌丝体。为了探讨形态菌丝的产生机制,对三种菌丝(气生菌丝、菌丝结和底生菌丝)的发育转录组进行了分析。结果表明,这三种菌丝体的直径和形态有明显差异。KEGG功能富集分析显示,底物菌丝的差异表达基因(DEGs)在核糖体和过氧化物酶体中富集,说明前期培养营养丰富,底物菌丝细胞在营养吸收阶段代谢旺盛。菌丝结的上deg主要富集于氧化磷酸化途径,说明在营养积累和生殖转化阶段,氧化磷酸化是菌丝形成的主要能量来源。空中菌丝体的上升基因主要富集于缬氨酸、亮氨酸和异亮氨酸的合成和降解途径,说明空中菌丝体的发生与培养后期氨基酸代谢有关,营养胁迫加速了无性孢子的繁殖。此外,通过qRT-PCR和转录组测序联合分析,验证了菌丝形成相关基因的重要作用。综上所述,本研究将为今后在中华玉螺培养中抑制气生菌丝体的发生,促进菌丝体向针尖原基的发育提供理论指导。
