Amoxicillin and thiamphenicol treatments may influence the co-selection of resistance genes in the chicken gut microbiota

General description of sequences After the quality filtering step, removal of chimeric fragments, and read merging, a total of 3,378,323 reads with 3007 different features was obtained, with an average of 27,244 sequences per individual sample. After quality filtering, none of the samples was excluded from the analysis of microbial…

Community succession and functional prediction of microbial consortium with straw degradation during subculture at low temperature

Changes of straw degradation characteristics at different culture stages Corn straw degradation ratio Corn straw weight loss in M44 at F1 reached 35.90% at 15 ℃ for 21 days, which was greater than that at F5, F8, and F11 by 2.33%, 3.01%, and 3.35%, respectively. There were no significant differences between…

Simulated global warming affects endophytic bacterial and fungal communities of Antarctic pearlwort leaves and some bacterial isolates support plant growth at low temperatures

Sample collection Colobanthus quitensis samples were collected at King George Island near the Henryk Arctowski Polish Antarctic Station, Maritime Antarctica (62°14’ S, 58°48’ W) during the summer season (February 2018). Samples were collected inside the Antarctic Specially Protected Area (ASPA) 128 using permits provided by The Chilean Antarctic Institute (INACH)…

GWAS, MWAS and mGWAS provide insights into precision agriculture based on genotype-dependent microbial effects in foxtail millet

GWAS identifies genetic variations associated with agronomic traits in foxtail millet A total of 827 foxtail millet cultivars collected from China were sequenced and genotyped using common single-nucleotide polymorphisms (SNPs) based on a ~423 Mb Setaria italica cv. Zhanggu reference genome (v.2.3)27. In total, 161,562 SNPs were detected after stringent steps…

Dietary selection of metabolically distinct microorganisms drives hydrogen metabolism in ruminants

Volatile fatty acid production and absorption is modulated by diet Animals were adapted to a starch-rich diet by gradually increasing dietary concentrate content from 50 to 90% over the three 100-d experimental periods (Fig. 1A). With both diets, rumen structure and epithelial morphology were robust and rumen pH remained above 6.0…

Capturing Actively Produced Microbial Volatile Organic Compounds from Human-Associated Samples with Vacuum-Assisted Sorbent Extraction

This protocol describes the extraction of volatile organic compounds from a biological sample with the vacuum-assisted sorbent extraction method, gas chromatography coupled with mass spectrometry using the Entech Sample Preparation Rail, and data analysis. It also describes culture of biological samples and stable isotope probing. This protocol allows us to…

Metagenomics technology and microbial community diversity analysis methods

A large number of microorganisms in nature cannot be cultivated under laboratory conditions by pure culture methods, and the technical methods of traditional microbiology limit the research on environmental microorganisms. The rapid development of high-throughput omics technology has enabled humans to have an unprecedented understanding of the complex microbial communities…

Vertical stratification of the air microbiome in the lower troposphere

Significance Large-scale meteorological and biological data demonstrate the vertical stratification of airborne biomass. The previously described diel cycle of airborne microorganisms is shown to disappear at height. Atmospheric turbulence and stratification are shown to be defining factors for the scale and boundaries, dynamics, and natural variability of airborne biomass, resulting…

Basic logic and use of PERMANOVA for microbiome data

Basic logic and use of PERMANOVA for microbiome data 1 PERMANOVA is frequently used in microbiome studies when analyzing beta diversity. While I know that basics of PERMANOVA are similar to ANOVA (with some differences related to permutation), I have a hard time understanding the logic of this analysis in…
