“…On the other hand, M. phyllanthi are plant pathogens that can be delivered to the gastrointestinal tract through the consumption of vegetables and fruits. Patients with CD significantly reduce their consumption of legumes, and stone fruits, and thus, they have a lower abundance of plant-related fungi than healthy people following a varied diet[ 50 , 51 ].…”

BACKGROUND Numerous studies have shown that in Crohn’s disease (CD), the gut microbiota is of great importance in the induction and maintenance of inflammation in the gastrointestinal tract. Until recently, studies have focused almost exclusively on bacteria in the gut. Lately, more attention has been paid to the role of intestinal fungi. AIM To study the gut mycobiome analysis of pediatric patients with CD (in different stages of disease activity) compared to healthy children. METHODS Fecal samples were collected from patients: With active, newly diagnosed CD ( n = 50); active but previously diagnosed and treated CD ( n = 16); non-active CD and who were in clinical remission ( n = 39) and from healthy volunteers ( n = 40). Fungal DNA was isolated from the samples . Next, next generation sequencing (MiSeq, Illumina) was performed. The composition of mycobiota was correlated with clinical and blood parameters. RESULTS Candida spp. were overrepresented in CD patients, while in the control group, the most abundant genus was Saccharomyces . In CD patients, the percentage of Malassezia was almost twice that of the control ( P < 0.05). In active CD patients, we documented a higher abundance of Debaryomyces hansenii ( D. hansenii ) compared to the non-active CD and control ( P < 0.05) groups. Moreover, statistically significant changes in the abundance of Mycosphaerella , Rhodotorula , and Microidium were observed. The analyses at the species level and linear discriminant analysis showed that in each group it was possible to distinguish a specific species characteristic of a given patient population. Moreover, we have documented statistically significant correlations between: D. hansenii and patient age (negative); C. zeylanoides and patient age (positive); C. dubliniensis and calprotectin (positive); C. sake and calprotectin (positive); and C. tropicalis and pediatric CD activity index (PCDAI) (positive). CONCLUSION Mycobiome changes in CD patients, and the positive correlation of some species with calprotectin or PCDAI, give strong evidence that fungi may be of key importance in the development of CD.

“…are highly sought-after fruits owing to their appetizing taste, pleasant flavor, nutrient richness and derived functional ingredients ( Fan and Zhang, 2022 , Frabetti et al, 2021 , Kosińska-Cagnazzo et al, 2015 ). As an extremely perishable fruit, strawberries are easily infected by microorganisms during storage and are rattled during transportation, thereby reducing their quality and edible value ( Cybulska et al, 2022 ); therefore, strawberries must be processed immediately to ensure a longer shelf life ( Shehata et al, 2020 ), for which drying is regarded as an appropriate method ( Calín-Sánchez et al, 2020 , Karam et al, 2016 ). Drying of fresh fruits and vegetables refers to the use of drying techniques to reduce water content until the water activity is <0.4 for long-term preservation ( Wu et al, 2022 , Ghinea et al, 2022 ).…”

“…It is commonly applied to rhizosphere microbial communities, especially for the study of soil and plant inter-root microorganisms [ 11 ]. The relationship between microbial changes on the surface of fruits and vegetables, and quality is only partially explored [ 12 ]. Zhang et al [ 8 ] studied the changes in cherry surface microorganisms and distinguished differences in the surface microorganisms of rotten and unrotten cherries, but the changes in the cherries’ quality were not investigated.…”

Microbial contamination is one of the main reasons for the quality deterioration of postharvest blueberries during storage. In this study, we investigated the surface microbiota of blueberry fruits stored at different temperatures via high-throughput sequencing of the 16S and ITS rRNA genes. The results indicated that the α-diversity of the microbial communities in samples stored at 4 °C was much higher than that in samples stored at 25 °C. The composition of the bacterial and fungal communities on the surface of the blueberry fruits varied at different storage temperatures. Ascomycota, Basidiomycota, Anthophyta, Chlorophyta, Proteobacteria, and Cyanobacteria were the most abundant phyla in the bacterial community. Furthermore, five preservation quality indices were measured, and the influence on the α-diversity of the bacterial community was found to be significantly weaker than that of the fungal community. Based on the prediction of the bacterial flora function, the change in blueberry quality during storage was closely related to its surface microbial effect. This study provides a theoretical basis for an understanding of the microbiota on the surface of blueberry fruits to cause fruit spoilage, and the development of a targeted inhibition technology to preserve blueberry fruits under different storage and transportation environments.
