The two Gram-negative bacterial strains S1 and S4 were isolated from activated sludge of an industrial waste water treatment plant and exhibited a stable capability to degrade 2,4-dichlorophenol, 4-chloro-2-methylphenol, 4-chlorophenol and phenol. The cells were short rods with a polar flagellum, being mesophilic, strictly aerobic, oxidase-positive, and chemoorganotrophic. They utilized a range of amino acids, but only a restricted number of carbohydrates. Reassociation experiments with DNA from strains S1 and S4 revealed high interstrain similarity, indicating, that both strains belong to the same species. The phylogenetic position was determined by comparison of the almost complete 16S rDNA sequence of strain S1 with sequences of related bacteria. Strain S1 clustered with members of the alpha-2 subgroup of the Proteobacteria by forming a separate lineage within the radiation of Mesorhizobium, Phyllobacterium and Sinorhizobium. Both strains can be differentiated from members of related taxa by a set of physiological and chemotaxonomic properties including the ability to grow with norvaline, L-tryptophan, putrescine, glutarate and malonate, and by the presence of spermidine as major polyamine and of 12:0 3OH as fatty acid. Strain S1 is described as type strain of a new species and assigned to a new genus with the proposed name Defluvibacter lusatiae.

Aquamicrobium is an aerobic gram-negative rod which until recently had only been isolated from wastewater and contaminated soil. In 2021, two cases of Aquamicrobium infection in humans were reported. Both were cases of endophthalmitis following cataract surgery.

Here, we report the draft genome sequence of Aquamicrobium lusatiense NLF2-7, a Gram-negative, aerobic, non-flagellum-forming, rod-shaped bacterium that was isolated from livestock wastewater in South Korea. The assembled genome sequence is 5,201,486 bp, with 4,972 protein-coding sequences in 12 contigs, and possess the genes for the sulfur oxidation pathway.

Purpose: To report a case of chronic endophthalmitis caused by following phacoemulsification surgery.
Observations: A 71 year-old woman was referred for chronic ocular inflammation after cataract surgery. Serologic testing was negative for common infectious etiologies.

An aerobic, Gram-stain negative, short rod-shaped, asporogenous, non-motile bacterium designated strain NK8 was isolated from a chlorobenzoate contaminated soil in China. Strain NK8 was observed to grow optimally at pH 7.0, 30 °C and in the absence of NaCl in LB medium.
