Microbial Profiles of Rhizosphere and Bulk Soil Microbial Communities of Biofuel Crops Switchgrass (Panicum virgatum L.) and Jatropha (Jatropha curcas L.)

Table 1

Diversity indices calculated from PLFA and LH-PCR data. Means followed by the same letters (a, b) in a column with method differ significantly.

	Rhizosphere (switchgrass)	33.66	0.88	3.08a
	Bulk (jatropha)	32.26	0.87	3.01b
	Rhizosphere (jatropha)	32.33	0.88	3.02b
LH-PCR	Bulk (switchgrass)	17.66	0.85	2.49
	Rhizosphere (switchgrass)	18.33	0.88	2.53
	Bulk (jatropha)	18.00	0.89	2.55
	Rhizosphere (jatropha)	18.33	0.89	2.56
