Microbial Resources

Raw milk and fermented milk are rich in microbial resources, which are essential for the formation of texture, flavor and taste. In order to gain a deeper knowledge of the bacterial and fungal community diversity in local raw milk and home-made yogurts from Sayram town, Baicheng county, Akesu area, southern of Xinjiang, China,30 raw milk and 30 home-made yogurt samples were collected and experiment of high-throughput sequencing was implemented.The results of experiments revealed the species of fungi in raw milk was the most, and the species of bacteria in fermented milk was the least.Based on principal component analysis (PCA), it was found that the bacterial and fungal community structure differed in samples from two types of dairy products.And the presence of 15 bacterial and 12 fungal phyla, comprising 218 bacterial and 495 fungal genera respectively, among all samples. Firmicutes and Ascomycota,Lactobacillus and Candida were the predominant phyla and genera of bacteria and fungi, respectively. The results indicated that the microbial community of raw milk differs from home-made yogurts due to sampling location and manufacturing process. The study suggested that high-throughput sequencing could provide a better understanding of microbiological diversity as well as lay a theoretical foundation for selecting beneficial microbial resources from this natural yogurt.

Abstract Background The fungal communities inhabiting natural Ophiocordyceps sinensis play critical ecological roles in alpine meadow ecosystem, contribute to infect host insect, influence the occurrence of O. sinensis, and are repertoire of potential novel metabolites discovery. However, a comprehensive understanding of fungal communities of O. sinensis remain elusive. Therefore, the present study aimed to unravel fungal communities of natural O. sinensis using combination of high-throughput sequencing and culture-dependent approach. Results A total of 280,519 high-quality sequences, belonging to 5 fungal phyla, 15 classes, 41 orders, 79 families, 112 genera, and 352 putative operational taxonomic units (OTUs) were obtained from natural O. sinensis using high-throughput sequencing. Among of which, 43 genera were identified in external mycelial cortices (EMC), Ophiocordyceps, Sebacinia, Archaeorhizomyces were predominant genera with the abundance of 95.86%, 1.14%, 0.85%, respectively. Total 66 genera were identified from soil microhabitat, Inocybe, Archaeorhizomyces, Unclassified Thelephoraceae, Tomentella, Thelephora, Sebacina, Unclassified Ascomycota, Unclassified Fungi were predominant genera with an average abundance of 53.32%, 8.69%, 8.12%, 8.12%, 7.21%, 4.6%, 3.08% and 3.05%, respectively. The fungal communities in external mycelial cortices (EMC) were significantly distinct from the soil microhabitat (Soil). Meanwhile, seven culture media that benefit for the growth of O. sinensis were used to isolate culturable fungi at 16 °C, resulted in 77 fungal strains isolated for rDNA ITS sequence analysis, belonging to 33 genera, including Ophiocordyceps, Trichoderma, Cytospora, Truncatella, Dactylonectria, Isaria, Cephalosporium, Fusarium, Cosmospora, Paecilomyces, etc.. Among all culturable fungi, Mortierella and Trichoderma were predominant genera of total isolates. Conclusions The significantly distinction and overlap in fungal community structure between two approaches highlight that integration of approaches would generate more information than either of them. Our finding is the first investigation of fungal community structure of natural O. sinensis by two approachs, provide new insight into O. sinensis associated fungi, and support that microbiota of O. sinensis is an untapped source for novel bioactive metabolites discovery.

Abstract: High-throughput sequencing was used to analyze the microbial communities in the muscle samples of hairtail fish to study their diversity and dynamic changes during cold-chain circulation. The results showed that the richness and diversity of the microbial community in hairtail fish had a transient decline in 0–24 h and decreased after the first rise during 24–216 h. The diversity and richness of bacteria in cold-chain hairtail fish reached the maximum at 168 h. The Shannon and Simpson diversity indices of the bacteria were 2.96 and 0.16, respectively, and their ACE and Chao1 richness indices were 254.84 and 155.10, respectively. In addition, the dominant bacteria were Proteobacteria in the phylum level, Gammaproteobacteria in the class level, Pseudomonadales in the order level, Pseudomonadaceae in the family level, and Pseudomonas in the genus level, and their relative abundance were 80.52%, 72.11%, 76.68%, 23.25%, and 53.50%, respectively. In this study, the structure of bacterial flora and the dominant bacteria in cold-chain hairtail fish were analyzed by high-throughput sequencing to provide a basis for exploring how to maintain the freshness of hairtail fish and for predicting the shelf-life of hairtail fish.
