Bacterial endophytes involved in the phytoremediation of organic pollutants from contaminated water (a summary of the endophyte’s potential for deterioration is also provided)

Site	Host	Plant parts	Endophytes	Organic pollutants	Degradation capacity	References
In vitro experiment	Yellow lupine	Root and shoot	B. cepacia BU0072, B. cepacia VM1330, and B. cepacia G4	Toluene	Compared to control plants and plants inoculated with B. cepacia BU0072, yellow lupine inoculated with B. cepacia VM1330 released 50–70% less toluene in the upper compartment	[22]
In vitro experiment	Populus sp. (Salicaceae)		B. cepacia VM1468, B. cepacia BU61	Toluene	Poplar cuttings inoculated with B. cepacia VM1468 released about 5 times less toluene from the leaves compared to non-inoculated plants or plants inoculated with B. cepacia BU61	[227]
Greenhouse experiment; Hasselt University campus; Belgium	Yellow lupine		B. cepacia VM1468	TCE and Ni	Inoculation of B. cepacia VM1468 resulted in successful Ni uptake and reduced TCE evaporation by 90% in contaminated groundwater	[248]
Greenhouse experiment; Hasselt University campus; Belgium	Populus sp. (Salicaceae)		Pseudomonas putida W619-TCE	TCE	Inoculation of Pseudomonas putida W619-TCE induced plant growth promotion and reduced the phytotoxicity of TCE when grown hydroponically	[251]
