Amylases are among the most important enzymes for biotechnological and industrial applications. The present work aimed to analyse the use of agro-industrial waste as a low-cost substrate to the obtention of the amylase by the fungus Trichoderma stromaticum AM7 (CCMB617P) under solid state fermentation (SSF). The fungus was able to produce amylase using solely peach palm waste as a substrate (29.2 U/gds), however when a simplex centroid mixture design was applied to optimise the composition of the nitrogen source, peptone, and ammonium phosphate (7:3 w/w) in a total of 1% were added and an increase of the 45% (42.4 U/gds) was observed in relation to the activity initially obtained. The physicochemical characterisation of amylase revealed the optimum activity at pH 4.0 and temperature 50 °C to 60 °C. The amylase retained around 90% of its activity in a pH range from 4.0 to 7.0 and a temperature 40 °C to 70 °C, and 60% in a range from 80 °C to 100 °C, for up to 1 h. Amylase showed an increase in its activity with Al2+, Ag2+, and Co2+, however, the Cu2+negatively influenced the enzymatic activity. The enzyme was stable in the presence of SDS and β-mercaptoethanol. The cost-effective enzyme extraction and stable amylase highlight its strong potential in industry applications, especially in food processes.

The order Agaricales was divided into eight suborders. However, the phylogenetic relationships among some suborders are largely unresolved, and the phylogenetic positions and delimitations of some taxa, such as Sarcomyxaceae and Tricholomopsis, remain unsettled. In this study, sequence data of 38 genomes were generated through genome skimming on an Illumina sequencing system. To anchor the systematic position of Sarcomyxaceae and Tricholomopsis, a phylogenetic analysis based on 555 single-copy orthologous genes from the aforementioned genomes and 126 publicly accessible genomes was performed. The results fully supported the clustering of Tricholomopsis with Phyllotopsis and Pleurocybella within Phyllotopsidaceae, which formed a divergent monophyletic major lineage together with Pterulaceae, Radulomycetaceae, and Macrotyphula in Agaricales. The analysis also revealed that Sarcomyxaceae formed a unique major clade. Therefore, two new suborders, Phyllotopsidineae and Sarcomyxineae, are proposed for the two major lineages. Analyses of 450 single-copy orthologous genes and four loci suggested that Tricholomopsis consisted of at least four clades. Tricholomopsis is subsequently subdivided into four distinct sections. Seventeen Tricholomopsis species in China, including six new species, are reported. Conoloma is established to accommodate T. mucronata. The substrate preference of Tricholomopsis species and the transitions of the pileate ornamentations among the species within the genus are discussed.

Russula is the largest genus in the Russulales and is widespread throughout the world. Almost all Russula species are known to be ectomycorrhizal with high ecological and edible values, and some are lethal poisonous. In this study, four new species belonging to the subgenus Russula crown clade are identified based on morphological and phylogenetic evidence from the Xizang Autonomous Region and other provinces of China. Morphologically, Russula paragraveolens (sect. Polychromae, subsect. Xerampelinae) is mainly characterised by a cherry red to blood red pileus centre, a reddish orange pileus margin; R. pseudograveolens (sect. Polychromae, subsect. Xerampelinae) is characterised by a violet brown to brownish red pileus centre, a pale red to pastel red pileus margin and short basidia; R. shigatseensis (sect. Flavisiccantes, subsect. Lepidinae) is characterised by a brownish orange to madder red pileus centre, pinkish red pileus margin, and having lateral branches or branches of hyphal terminations in pileipellis; R. yadongensis (sect. Tenellae, subsect. Laricinae) is characterised by a dark purplish red pileus centre with brownish purple tints and having isolated to clustered spines of spore ornamentations. Their distinct taxonomic status is confirmed by the positions of the four new species in both the ITS and 4-locus (nucLSU, mtSSU, rpb2, tef1) phylogenetic trees.

Ginseng black spot, caused by Alternaria panax, is one of the most common diseases of Panax ginseng, which usually causes serious yield loss of ginseng plants. However, the pathogenic mechanism of A. panax has not been clarified clearly. Mycotoxins produced by phytopathogens play an important role in the process of infection. Previous study reported that dibutyl phthalate (DBP) identified from the metabolites of A. panax is a potent mycotoxin against P. ginseng. However, more evidence suggests that DBP is one of the constituents of plasticisers. To identify mycotoxins from A. panax and evaluate their phytotoxicity on the leaves of P. ginseng, different chromatographic, spectral and bioassay-guided methods were used together in this report. As a result, tyrosol (1), 3-hydroxy-3-(4-methoxyphenyl) propanoic acid (2), and 3-benzylpiperazine-2,5-dione (3) were isolated and characterised from the extract of A. panax, in which compounds 1 and 2 showed phytotoxic activity on ginseng leaves. Furthermore, DBP was confirmed to come from the residue of ethyl acetate through UPLC-MS/MS analysis, and displayed no phytotoxicity on ginseng leaves based on biological experiments. The results in this report first revealed that tyrosol (1), and 3-hydroxy-3-(4-methoxyphenyl) propanoic acid (2) not DBP were the potent mycotoxins of A. panax.

Rock-inhabiting fungi (RIF) are slow-growing microorganisms that inhabit rocks and exhibit exceptional stress tolerance owing to their thick melanised cell walls. This study reports the identification of a novel rock-inhabiting fungus, Cladophialophora brunneola sp. nov. which was isolated from a karst landform in Guizhou, China, using a combination of morphological and phylogenetic analyses. The genome of C. brunneola was sequenced and assembled, with a total size of approximately 33.8 Mb, encoding 14,168 proteins and yielding an N50 length of 1.88 Mb. C. brunneola possessed a larger proportion of species-specific genes, and phylogenomic analysis positioned it in an early diverged lineage within Chaetothyriales. In comparison to non-RIF, C. brunneola displayed reduction in carbohydrate-active enzyme families (CAZymes) and secondary metabolite biosynthetic gene clusters (BGCs). Transcriptome analysis conducted under PEG-induced drought stress revealed elevated expression levels of genes associated with melanin synthesis pathways, cell wall biosynthesis, and lipid metabolism. This study contributes to our understanding of the genomic evolution and polyextremotolerance exhibited by rock-inhabiting fungi.

Candida albicans is one of the most common opportunistic fungi in cancer patients. This study explored the influence of C. albicans on gut microbiota in oral tumour-bearing mice by means of 16S rRNA sequencing and ITS sequencing. It was found that C. albicans infection induced the decrease of alpha diversity of bacteria and fungi in the gut microbiome. For the bacteria, C. albicans caused the reduction of Ralstonia, Alistipes, Clostridia UCG-014, Ruminococcus, and Lachnospiraceae NK4A136 group. For the fungi, C. albicans inhibited the growth of other fungi including Aspergillus, Cladosporium, and Bipolaris. The neutralisation of γδT cells partly alleviated the out-of-balance of Firmicutes/Bacteroidota (F/B) ratio in the gut caused by C. albicans infection. However, γδT cell neutralisation boosted the overgrowth of C. albicans. Additionally, IL-17A neutralisation aggravated the microbial dysbiosis of bacteria and fungi caused by C. albicans infection. Further analysis indicated that C. albicans overgrowth might influence the correlations between fungal and bacterial kingdoms. In conclusion, C. albicans infection disturbed the gut microbiota of both bacteria and fungi in oral tumour-bearing mice, which may be associated with the intestinal immune components including γδT cells and IL-17A.

Species in the class Myxomycetes (or Myxogastrea) are essential components of biodiversity and play important ecological roles in terrestrial ecosystems, especially in forests. Studies on the taxonomy and diversity of these organisms started late in China. However, significant progress in China has been made in modern taxonomic studies on myxomycetes based on long-term species surveying and specimen collecting. The existing achievements have shown that comprehensive and continuous studies on the taxonomy and diversity of myxomycetes in China have the potential to enhance global biodiversity and improve the geographic distribution pattern of myxomycetes. Therefore, building on the current research foundation and expanding myxomycete research in a wider and more in-depth approach is imperative.

The application of interleukin-17 (IL-17) inhibitors, including secukinumab, ixekizumab, brodalumab, and bimekizumab, are associated with elevated risk of candidiasis. These medications interfere with the IL-17 pathway, which is essential for maintaining mucosal barriers and coordinating the immune response against Candida species. The observational data and clinical trials demonstrate the increased incidence of candidiasis in individuals treated with IL-17 inhibitors. Brodalumab and bimekizumab pose a greater risk than secukinumab in eliciting candidiasis, whereas the data regarding ixekizumab are equivocal. Higher doses and prolonged treatment duration of IL-17 inhibitors increase the risk of candidiasis by compromising the immune response against Candida species. Prior to prescribing IL-17 inhibitors, healthcare professionals should comprehensively evaluate patients’ medical histories and assess their risk factors. Patients should be educated on the signs and symptoms of candidiasis to facilitate early detection and intervention. Future research should focus on identifying the risk factors associated with candidiasis in patients receiving IL-17 inhibitors. Prospective studies and long-term surveillance are required to explore the impact of specific inhibitors on the incidence and severity of candidiasis and to evaluate the effectiveness of combination therapies, such as concurrent use of IL-17 inhibitors and prophylactic antifungal agents.

Inonotus obliquus, also known as Chaga, is a medicinal mushroom that has been used for therapeutic purposes since the sixteenth century. Collections of folk medicine record the application of Chaga for the treatment of diseases such as gastrointestinal cancer, diabetes, bacterial infection, and liver diseases. Modern research provides scientific evidence of the therapeutic properties of I. obliquus extracts, including anti-inflammatory, antioxidant, anticancer, anti-diabetic, anti-obesity, hepatoprotective, renoprotective, anti-fatigue, antibacterial, and antiviral activities. Various bioactive compounds, including polysaccharides, triterpenoids, polyphenols, and lignin metabolites have been found to be responsible for the health-benefiting properties of I. obliquus. Furthermore, some studies have elucidated the underlying mechanisms of the mushroom’s medicinal effects, revealing the compounds’ interactions with enzymes or proteins of important pathways. Thus, this review aims to explore available information on the therapeutic potentials of Inonotus obliquus for the development of an effective naturally sourced treatment option.

Collections of folk medicine record the application of Chaga for the treatment of diseases such as gastrointestinal cancer, diabetes, bacterial infection, and liver diseases. Modern research provides scientific evidence of the therapeutic properties of I. obliquus extracts, including anti-inflammatory, antioxidant, anticancer, anti-diabetic, anti-obesity, hepatoprotective, renoprotective, anti-fatigue, antibacterial, and antiviral activities. Various bioactive compounds, including polysaccharides, triterpenoids, polyphenols, and lignin metabolites have been found to be responsible for the health-benefiting properties of I. obliquus. Furthermore, some studies have elucidated the underlying mechanisms of the mushroom’s medicinal effects, revealing the compounds’ interactions with enzymes or proteins of important pathways. Thus, this review aims to explore available information on the therapeutic potentials of Inonotus obliquus for the development of an effective naturally sourced treatment option.","PeriodicalId":18833,"journal":{"name":"Mycology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135616537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
