TABLE 1.

Comparison of AOM and sulfate reduction rates in Black Sea microbial mats determined in this and other studies^a

Reference	AOM rate (μmol g [dry wt]⁻¹ day⁻¹)	Sulfate reduction rate (μmol g [dry wt]⁻¹ day⁻¹)	Methane-dependent sulfate reduction rate (μmol g [dry wt]⁻¹ day⁻¹)	Incubation time (days)
This study (expt 1a)	20.9	10.9		62
	9.4	7.3
	8.2	4.3
This study (expt 1b)	13.9, 12.4, 7.8			109
23	18 ± 12 (3)^b	19 ± 1 (3)^b		5
			34 ± 5.8 (6)^b	60
25			41 ± 16 (38)^b	60
37			9.1 ± 1.6 (3)^b	242

AOM and (gross) sulfate reduction rates were determined by incubation with radiotracers. Methane-dependent sulfate reduction rates were determined from the difference in the sulfide production rates with and without methane and were equal to AOM rates.
