We have isolated a new strain of Acidovorax temperans strain LMJ (hereafter called strain LMJ) from a contaminated Tris-Acetate-Phosphate (TAP) medium plate of a green micro-alga Chlamydomonas reinhardtii strain LMJ.SG0182 (a Chlamydomonas Library project (CLiP) strain). We sequenced the whole genome of the strain LMJ using the PacBio Sequel II technology and have submitted it to NCBI along with the SRA and PacBio methylation motif data. We present the whole genome sequence of this strain that offer insights into its coding and non-coding genes and its nearest taxonomic neighbors.

A novel Acidovorax temperans strain, designated as LMJ and subsequently referred to by this name, was isolated from a contaminated Tris Acetate Phosphate (TAP) medium culture plate of Chlamydomonas reinhardtii, at the University of West Georgia (Geolocation data: Carrollton, Georgia ; 1,102 ft (336 m); 33.5730 N 85.1037 W (1). Strain LMJ has one cirucular chromosome and two circular plasmids pEP1 and pJG1). We report the complete genome sequence of LMJ and offer insights into its genomic characteristics.
Acidovorax temperans strain LMJ was isolated from a contaminated Tris Acetate Phosphate (TAP) medium culture plate of the green micro-alga Chlamydomonas reinhardtii strain LMJ.SG0182, a Chlamydomonas Library project (CLiP) strain.
Genomic DNA was isolated from the Lysogeny Broth (LB) medium-grown Acidovorax temperans strain LMJ (colony # 10) using the Qiagen’s blood and cell culture DNA mini kit.
After determination of genomic DNA purity and DNA quantification, the DNA sample was shipped to Georgia Genomics and Bioinformatics Core (GGBC) at the University of Georgia (Athens, GA). At GGBC, the sample was processed for preparation of the PacBio Single Molecule Real Time (SMRT) bell sequencing library according to the protocol given in the PacBio technical manual for template preparation and sequencing (please see QC section for more details). The SMRT bell sequencing library was barcoded and sequenced with two additional barcoded microbial SMRT Bell sequencing libraries in a single SMRT cell using PacBio SMRT Continuous Long Read sequencing on the PacBio Sequel II instrument. SMRT Link version 9 was used as an interface to manage the workflow from sample setup to result analysis.
Reads were first assembled using the SMRT Link version 9 software tools (has inbuilt HGAP version 4:0). The pipeline was run at default with a pre-specified approximately estimated genome size of 5.3Mb (based on available complete genome sizes of various Acidovorax sp. on NCBI). After assembly, the assembly metrics for each sample along with HMM predicted genes were determined by running Quast ver. 5.02. Genome was also assembled with FLYE version 2.9.1 for statistical confidence.
The LMJ genome consists of one circularized chromosome and two circularized plasmids comprising a total of 4,730,769 bp with an overall G+C content of 63.18%. Genome coverage was calculated using the formula: Number of Subread Bases (mapped)/Genome Size = 12,367,684,489/4,730,769 = 2614X. Genome coverage (based on PacBio polished assembly in the PacBio assembly report): 2535.7X.
