“…In our study, the family Sphingomonadaceae exhibits the higher relative abundance within the root endophytic communities from high and low pollution treatments ( Figure 3 ). This is not surprising since this family comprises of well-known genera for their ability to degrade a variety of organic pollutants ( Acosta-González et al, 2015 ; Waigi et al, 2017 ). This family together with the Methylophilaceae , Burkholderiaceae , and Xanthobacteraceae are the marker families in the root microbiome at high pollution treatments ( Figure 6 ).…”

Plants and their associated bacteria play a crucial role in constructed wetlands. In this study, the impact of different levels of pollution and bioaugmentation with indigenous strains individually or in consortia was investigated on the composition of the endophytic microbial communities of Juncus acutus. Five treatments were examined and compared in where the wetland plant was exposed to increasing levels of metal pollution (Zn, Ni, Cd) and emerging pollutants (BPA, SMX, CIP), enriched with different combinations of single or mixed endophytic strains. High levels of mixed pollution had a negative effect on alpha diversity indices of the root communities; moreover, the diversity indices were negatively correlated with the increasing metal concentrations. It was demonstrated that the root communities were separated depending on the level of mixed pollution, while the family Sphingomonadaceae exhibited the higher relative abundance within the root endophytic communities from high and low polluted treatments. This study highlights the effects of pollution and inoculation on phytoremediation efficiency based on a better understanding of the plant microbiome community composition.

“…Sphingomonads have been intensively studied in the past years, due to their remarkable ability to degrade a wide range of recalcitrant compounds, including polycyclic aromatic hydrocarbons, nonylphenols, chlorinated dibenzofurans, etc ., and ubiquitous distribution in different niches [1–5]. In fact, the word ‘Sphingomonads’ referred to a collective bacterial group of Alphaproteobacteria , accommodating Sphingomonas and its closely related genera in the family Sphingomonadaceae including Sphingopyxis , Novosphingobium , Sphingobium , etc .…”

During a phylogenetic analysis of Sphingorhabdus and its closely related genera in the family Sphingomonadaceae , we found that the genus Sphingorhabdus and the species Sphingopyxis baekryungensis might not be properly assigned in the taxonomy. Phylogenetic, phenotypic and chemotaxonomic characterizations clearly showed that the genus Sphingorhabdus should be reclassified into two genera (Clade I and Clade II), for which the original genus name, Sphingorhabdus , is proposed to be retained only for Clade I, and a new genus named as Parasphingorhabdus gen. nov. is proposed for Clade II with four new combinations: Parasphingorhabdus marina comb. nov., Parasphingorhabdus litoris comb. nov., Parasphingorhabdus flavimaris comb. nov. and Parasphingorhabdus pacifica comb. nov. Moreover, Sphingopyxis baekryungensis should represent a novel genus in the family Sphingomonadaceae , for which the name Novosphingopyxis gen. nov. is proposed, with a combination of Novosphingopyxis baekryungensis comb. nov. The study provides a new insight into the taxonomy of closely related genera in the family Sphingomonadaceae .

“…Initial characterization of the plant growth-promoting properties of this organism revealed that it is able to produce siderophores and indole-3-acetic acid, as well as to induce root growth. There are various examples of plant growth-promoting organisms within the Sphingomonadaceae ( 4 – 6 ), but the genus Sphingobium is largely limited to organisms that are able to break down xenobiotic compounds ( 7 ).…”
