1.3 Gbp) were processed to remove SMRT bell adapters, short and low-quality reads (< 80% accuracy) using SMRT Analysis version 2.3 ( A total of 155,828 filtered reads (average length, 8.9 Kb) were used for de novo assembly using Celera Assembler , with self-correction of the PacBio reads. A total of 1091 Mb paired-end Illumina reads screened from a 500-bp genomic library were mapped using SOAP to the bacterial plasmid database for tracing the presence of any plasmid and filling the gaps. The de novo assembly resulted in five contigs, representing the K. michiganensis BD177 complete genome of 6,812,698 bp with GC content % in a single chromosome and four plasmids. The annotated genome contains 6714 genes, 25rRNA genes, and 86 tRNA genes (Table 1).
16S rRNA phylogenetic analysis and you will phenotypic regarding remote filter systems BD177
Maximum parsimony founded and limit possibilities phylogenetic trees utilising the succession that encodes into the 16S rRNA gene indicated that brand new closest varieties so you’re able to BD177 are K. michiganensis and K. oxytica (Even more file step 1: Fig. S1, Extra document dos: Desk S1). Evolutionary divergence point of 16S rRNA gene succession anywhere between BD177 and you will K. michiganensis E718 was minimum well worth (BD177 against K. michiganensis E718: 0.0079) certainly one of all the sequences. Biochemical testing was did on the BD177 of the API20E to ensure its status throughout the K. oxytoca and you may K. michiganensis. Biochemical functions away from K. oxytoca ATCC13182(T)(=NCTC13727) and you will K. michiganensis W14(T)(= DSM2544) was taken from BacDive Webservices pared with K. oxytoca ATCC13182(T) and K. michiganensis W14(T), BD177 is similar with W14 in the ?-galactosidase enzyme self-confident and you will urease bad, exact same that have ATCC13182(T) for the arginine dihydrolase self-confident. But not, BD177 does not have the employment feature of citrate while the only carbon provider, distinctive from each other style of challenges (Dining table dos).
Pan-genome research
In this study, we considered the 128 publicly available genome assemblies for the Klebsiella sp. (Additional file 3: Table S2). Of these genomes, 26 were originally annotated as K. aerogenes, https://datingranking.net/tr/imeetzu-inceleme/ 13 were K. michiganensis, 27 were K. oxytoca, and 15 were K. pneumoniae. 25 were K. quasipneumoniae, 1 was K. quasivariicola, 21 were K. variicola. The type strain genome of each species is included in these genomes. These genome assemblies were passed strict quality control (N75 values of > 10,000 bp, < 500 undetermined bases per 100,000 bases, > 90% completeness and < 5% contamination) by quast and checkm (Additional file 4: Table S3). This resulted in a total of 118 Klebsiella sp. strains studied, where ten low-quality genome assemblies were discarded. The GC contents of the species K. michiganensis, K. oxytoca, K. pneumoniae, K. variicola, and K. quasipneumoniae showed low intraspecies variation, with respective average values of , , , and % (Fig. 1a), whereas larger interspecies diversity was observed. In contrast, K. aerogenes genomes can be divided into two groups, a large group showing a GC content in the range of that of Klebsiella aerogenes ( to %) and a small group of two genomes ( and %) showing a much greater GC content, similar to that of the K. pneumoniae, K.variicola and K. quasipneumoniae genomes (respective average values about 57%). Based on GC content of the genome, K. pneumoniae, K.variicola, K. quasivariicola, and K. quasipneumoniae were considered as a high GC group content, and K. michiganensis and K. oxytoca were considered as a low GC content group. The genome sequence of our new isolate, which we designated K. michiganensis BD177 with % GC content (Table 1), shows a similar to that of the low GC content Klebsiella sp. group (Fig. 1a).
