Degradation of single PAHs by Neptunomonas strains

PAH	% recoverya
	Strain NAG-2N-113	Strain NAG-2N-126
Napththalene	0b	0b
1-Methylnaphthalene	34 ± 2	20 ± 4
2-Methylnaphthalene	12 ± 7b	1 ± 1b
2,6-Dimethylnaphthalene	0	107 ± 37
Biphenyl	91 ± 14	89 ± 7
Acenaphthene	102 ± 6	92 ± 5
Phenanthrene	0b	92 ± 17
Fluorene	80 ± 19	90 ± 8

^aPercentage of the PAH remaining after 7 days (mean ± standard deviation; n = 3). The levels of PAH recovery from control tubes containing no bacteria were 85 to 100%. 

^bPAH used as a sole carbon and energy source.
