Profiling bacterial communities by MinION sequencing of ribosomal operons
BACKGROUND An approach utilizing the long-read capability of the Oxford Nanopore MinION to rapidly sequence bacterial ribosomal operons of complex natural communities was developed. Microbial fingerprinting employs domain-specific forward primers (16S rRNA subunit), reverse primers (23S rRNA subunit), and a high-fidelity Taq polymerase with proofreading capabilities. Amplicons contained both ri...
متن کاملOligonucleotide profiling for discriminating bacteria in bacterial communities.
Based on the relative ratios of di- and tri-nucleotides in the DNA sequences, the profiles of 164 genome sequences from 152 representative microbial organisms were computed. By comparing the profiles of the genomes and their substrings with length 500 bps, the fluctuations of the relative abundances of di- and tri-nucleotides of these genomic sequences were analyzed. A new method to discriminat...
متن کاملDenaturing gradient gel electrophoresis profiling of bacterial communities composition in Arabian Sea.
Denaturing gradient gel electrophoresis (DGGE) was used to elucidate spatial and temporal variations in bacterial community composition (BCC) from four locations along the central west coast of India. DNA extracts from 36 water samples collected from surface, mid-depth (-10 m) and dose to bottom (-20 m) during premonsoon, postmonsoon, monsoon were analyzed by PCRfor amplifying variable region o...
متن کاملMolecular Taxonomic Profiling of Bacterial Communities in a Gilthead Seabream (Sparus aurata) Hatchery
As wild fish stocks decline worldwide, land-based fish rearing is likely to be of increasing relevance to feeding future human generations. Little is known about the structure and role of microbial communities in fish aquaculture, particularly at larval developmental stages where the fish microbiome develops and host animals are most susceptible to disease. We employed next-generation sequencin...
متن کاملeffect of oral presentation on development of l2 learners grammar
this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
