Authors: Heo I, Hong K, Yang H, Lee HB, Choi YJ, Hong SB Abstract In order to elucidate the fungal diversity and community structure in freshwater environments, numerous fungal strains were isolated from freshwater, submerged soils, twigs, dead insects, etc. Among them, the present study has focused specifically on Aspergillus, Penicillium, and Talaromyces species, which produce diverse useful metabolites in general. Twelve strains of Aspergillus isolated were identified as A. japonicus (n = 5), A. tubingensis (3), A. niger (2), and A. flavus (2), 10 strains of which belong to Aspergillus section Nigr...

Publication date: Available online 17 April 2019Source: LWTAuthor(s): Yue Tan, Renfeng Zhang, Guangjing Chen, Shasha Wang, Changfeng Li, Yao Xu, Jianquan KanAbstractNaturally fermented douchi always yields large amounts of biogenic amines (BAs). To improve the safety and quality of douchi and shorten its fermentation cycle, investigations were carried out using six selected microbial strains, including Aspergillus oryzae 2339 (Shanghai brewing 3.042), A. oryzae 41380, A. oryzae 40188, Mucor racemosus, Actinomucor elegans, and M. wutungqiao for douchi rapid fermentation. Results showed that the water content, pH, free amino...

Publication date: Available online 16 April 2019Source: Food ChemistryAuthor(s): Shuang Gu, Jun Wang, Yongwei WangAbstractEarly detection of Aspergillus spp. contamination in rice was investigated by electronic nose (E-nose) in this study. Sterilized rice artificially inoculated with three Aspergillus strains were subjected to GC-MS and E-nose analyses. Principle Component Analysis (PCA), Partial Least Squares Regression (PLSR), Back-propagation neural network (BPNN), Support Vector Machine (SVM) and Learning Vector Quantization (LVQ) were employed for qualitative classification and quantitative regression. GC-MS analysis ...

Conclusions MDSC are major players in the immunosuppressive scenario in cancer, thanks to their phenotype heterogeneity and critical interaction with several innate immune cells, thus representing a crucial target in oncology. Here we reviewed the interactions of MDSCs with NK cells. The contribution of key cytokines, chemokines and mediators active in this process have been discussed. We also described the contribution of MDSC on angiogenesis directly or indirectly through interactions with NK and immunosuppressive activities. A parallel of the cancer associated to the decidual counterpart of these cells is discussed, a...

In this study, we conducted an in-depth analysis of the FluG sequence, which revealed a single polypeptide containing a putative N-terminal amidohydrolase region linked to a putative C-terminal γ-glutamyl ligase region. Each region corresponded, separately and completely, to respective single function bacterial enzymes. Separate expression of these regions confirmed that the C-terminal region was essential for asexual development. The N-terminal region alone did not support conidial development, but contributed to increased conidial production under high nutrient availability. Point mutations directed at respective k...

Conclusions In conclusion, articles in this Research Topic made a very significant contribution to our understanding of the role played by environmental factors, dysbiotic conditions, and infections in triggering diseases. Since this is a rapidly expanding area of research, many other factors contributing to the onset of these diseases are not covered here. We are confident, however, that further studies will expand the list as well as bring a better understanding of mechanisms involved in the onset of autoimmune and autoinflammatory diseases. Author Contributions All authors listed have made a substantial, direct and i...

In this study, we attempted to find a DNA extraction protocol which could be effectively used to analyze both the bacterial and fungal community. We evaluated the effect of five DNA extraction methods (QIAamp DNA Stool Mini Kit, PureLinkTM Microbiome DNA Purification Kit, ZR Fecal DNA MiniPrepTM Kit, NucleoSpin® DNA Stool Kit, and IHMS protocol Q) on bacterial and fungal gut microbiome recovery using (i) a defined system of germ-free mice feces spiked with bacterial or fungal strains, and (ii) non-spiked human feces. In our experimental setup, we confirmed that the examined methods significantly differed in efficiency ...

Conclusion Lactobacillus pentosus was the predominant species found at industrial scale in Spanish table olives biofilms, albeit certain genotypes of L. plantarum were also detected. At genotype level, biodiversity was higher in the Spanish-style table olive biofilms than in those of directly brined olives. The multivariate analysis based on technological and probiotic data showed that the main 16 genotypes obtained could be clustered in 3 great phenotypes, with some strains with potential application as multifunctional starters (especially L. pentosus Lp13 and LpG1 genotypes). Data obtained in the present study showed th...
