Impact of Trichloroethylene Exposure on the Microbial Diversity and Protein Expression in Anaerobic Granular Biomass at 37°C and 15°C

Table 1

Specific Methanogenic Activity (SMA) of biomass sampled from R1 to R4 on day 235 of bioreactor trial, when influent TCE concentrations of R1 and R3 were 60 mg L⁻¹ [9] Values shown are expressed as mL CH₄ gVSS⁻¹ day⁻¹ and are means of triplicates with std. errors (std. deviation/√𝑛, 𝑛=3) given in parentheses.

Temperature	Biomass	Propionate	Butyrate	Ethanol
37°C	R1 (TCE)	123 (5)	124 (3)	160 (11)
	R2 (Control)	222 (2)	160 (33)	210 (28)
15°C	R3 (TCE)	82 (5)	14 (1)	51 (5)
	R4 (Control)	164 (1)	23 (2)	48 (11)
