TABLE 2.

PHB content (in %) of L. pneumophila strains as seen by FT-IR spectroscopy

Percentage values (mean values from three independent cultivations) were obtained from experimental FT-IR spectra with respect to the PHB content of Lpp WT in the PE phase. The data were normalized to the 100 (in bold) for WT (PE).

Lpp strain	EE	LE	PE	S
WT	45	37	100	46
Δketo	51	69	131	201
Δ0931–33	55	37	79	62
Δ0931–33/Δketo	84	100	152	203
Δ0650	12	10	15	10
