Genome of a culture that was harvested by filtration on 0.22 µm filters; DNA was extracted with the Quiagen MagAttract HMW DNA kit. Sequencing was done with Illuminia Novaseq 6000, trimming of reads with BBMap v36.x, assembly with SPAdes v3.12.0. The genome was manually polished in Geneious 10 by repeated rounds of read mapping. Completeness and contamination were assessed with CheckM.
