Sagebrush rhizosphere soil treatment with phenol at three different pHs

	Actinomycetes (CFU/g)	Non-actinomycetes (CFU/g)	Final pH (in soil)
Sample #1 (phosphate buffer pH 7.0 without phenol)	6.5 (±1.1) × 105	4.3 (±0.7) × 107	7.2
Sample #2 (phosphate buffer pH 7.0 with phenol)	1.3 (±0.2) × 105	3.3 (±1.1) × 104	7.0 (after addition of phenol)
Sample #3 (base treatment; Tris–HCl pH 8.0 without phenol)	1.9 (±0.3) × 106	1.2 (±0.2) × 107	7.7
Sample #4 (base treatment; Tris–HCl pH 8.0 with phenol)	7.8 (±0.4) × 104	9.1 (±2.6) ×  106	7.4 (after addition of phenol)
Sample #5 (acid treatment; phosphate buffer pH 3.0 without phenol)	1.7 (±0.1) × 106	4.8 (±0.4) × 106	3.3
Sample #6 (acid treatment; phosphate buffer pH 3.0 with phenol)	7.0 (±2.8) × 104	5.0 (±4.2) × 106	3.3 (after addition of phenol)
