We characterized the complete genome sequence of actinobacteriophage Yavru ( Siphoviridae ), a cluster FE bacteriophage infecting Arthrobacter globiformis NRRL B-2979; it was 89.5% identical to cluster FE phage Whytu, with a capsid width of 50 nm and a tail length of 90 nm. The genome was 15,193 bp in length, with 23 predicted protein-coding genes.

Xanthobacter aminoxidans is a Gram-negative pleomorphic and diazotrophic Knallgas bacillus that undergoes asymmetric budding of V-shaped branched cells during cell division. Like other Xanthobacter spp., cells are yellow from production of zeaxanthine dirhamnoside. We sequenced strain 14a T (= ATCC BAA-299 T ) and report a genome size of 5,829,486 bp with a G+C content of 67.9%.
