Pseudoxanthomonas is a genus of Gram-negative bacteria in the family Lysobacteraceae [1] from the phylum Pseudomonadota. [2] This genus is closely related phylogenetically with the genera Xanthomonas, Xylella, and Stenotrophomonas . [3] The genus was first distinguished in 2000 in biofilter samples, [4] and was later emended by Lee et al. [5] Some of the species in this genus are: P. mexicana, P. japonensis, P. koreensis, P. daejeonensis , and the type species P. broegbernensis .
1. Pseudoxanthomonas species exhibit an aptitude for growth in hostile chemical environments as evidenced by many studies. [MR1] Several Pseudoxanthomonas [MR2] strains have been isolated from hydrocarbon contaminated sites and show the ability to degrade polycyclic aromatic hydrocarbons such as chrysene, phenanthrene and pyrene [6] . Pseudoxanthomonas kaohsiungensis has been isolated from an oil-polluted site. Reveling this isolate displayed an ability to produce extracellular biosurfactants that can significantly reduce medium surface tension enabling bacterial growth on hydrophobic carbon sources such as olive oil. [7]
2. Certain Pseudoxanthomonas strains show strong tolerance to heavy metals; for example, Pseudoxanthomonasspadix ZSY-33 can withstand elevated copper concentrations using metal-resistance systems such as the Cus and Cop pathways. [8] Some Pseudoxanthomonas mexicana isolates show plant growth promoting traits and tolerance to arsenic; reported activities include auxin production, hydrogen cyanide production and nitrogen fixation that improved plant growth in contaminated soils.

[MR1]You could benefit from an opening sentence that encapsulates the points that follow.
[MR2]Genus and species name should always be italicized. Please do this throughout the text.
[MR3]Please make sure there are no typos at all!
[MR4]Start this as a new sentence. The previous one was too long.
[MR5]'can' instead of 'have the ability to'
[MR6]'enabling bacterial growth on' instead of 'and enable growth on'.
