Pseudomonas aeruginosa is a member of the family Pseudomonadaceae and is an aerobic Gram-negative rod. Pseudomonas aeruginosa is one of the most important nosocomial pathogens with a high intrinsic antibiotic resistance. Pseudomonas aeruginosa can cause a range of infections but rarely causes serious illness in healthy individuals without some predisposing factor. It predominantly colonizes damaged sites such as burn and surgical wounds, the respiratory tracts of people with underlying diseases and physically damaged eyes. From these sites, it may invade the body, causing destructive lesions or septicaemia and meningitis. Cystic fibrosis and immunocompromised patients are prone to colonization with P. aeruginosa, which may lead to serious progressive pulmonary infections.

Genus Pseudomonas is one of most diverse bacterial genera and a very important part of natural microbial communities. The genus belongs to family Pseudomonadaceae, order Pseudomonadales, class Gammaproteobacteria, phylum Proteobacteria, and kingdom Bacteria. Members of genus Pseudomonas are thin, rod-shaped, and usually unicellular, with a straight or curved long axis. They are non-spore-forming, Gram-negative, motile, and strictly aerobic. However, they may be anaerobic in some cases. They do not have the ability to form spores, stalks, or sheaths, as in Bacillus. Pseudomonas species are commonly found in aquatic environments, soil, humans, and animals (Hesse et al., 2018; Wisplinghoff, 2017). All Pseudomonas utilize molecular oxygen as a terminal oxidant. However, some Pseudomonas alternatively use denitrification as an anaerobic respiratory mechanism (Cheng et al., 2018). They obtain energy by utilizing organic and inorganic compounds (Li, Yu, et al., 2018).

The strains associated with the root of Vetiver belong to Pseudomonadaceae, Enterobacteriaceae, Aeromonadaceae and Micrococcaceae. Given their abilities in metabolizing sesquiterpenes (Del Giudice et al., 2008a), they may have the ability in OPs degradation. Because sesquiterpenes and OPs share the similarity that many of them are aromatic hydrocarbons (Chizzola, 2013; Buckle, 2015; Chandra, Sharma, Yadav, & Tripathi, 2018). Pseudomonadaceae and Enterobacteriaceae can possibly degrade OPs, such as endocrine disruptors including 2,3,6-trimethylphenol, 2-methoxyphenol (guaiacol), 2,6-dimethoxyphenol (syringol), methoxycinnamic acid, pentadecane, octadecanoic acid and trimethylsilyl ester (Kahlon, 2016; Chandra et al., 2018). OPs can be taken up by plants through leaves and roots (Namiki, Otani, & Seike, 2013; Zhang et al., 2017). The essential oil-associated endophytes may be the essential degraders of the OPs taken up in the roots (Barac et al., 2004).
A review of design, operational conditions and applications of microbial fuel cells

Pseudomonas aeruginosa is a gram-negative, aerobic rod belonging to the bacterial family Pseudomonadaceae and member of the Gamma Proteobacteria class of bacteria. Habermann and Pommer [65] used a variety of microorganisms. The various bacterial strains were P. aeruginosa, E. coli and Proteus vulgaris. Rabaey et al. [59] reported that exogenous mediators did not have to be included in a culture. These self-produced or endogenous chemical mediators, such as pyocyanin and related compounds produced by P. aeruginosa, can transfer electrons to an electrode and produce electricity in a MFC.
