“…The presence of unstable collectors in the low pH culture can limit the availability (i.e., transfer) of oxygen (xanthates are unstable in acidic solutions, and their instabilities increase by decreasing the pH [7,[22][23][24]). These reactions' inhibitory effect increase the DO 2 value [36][37][38]. Thus, a decrease in the DO 2 value shows a positive effect of reagents on activities of microorganisms.…”

“…However, the disproportion rate may be slower at low temperature. The MIC of KSCN to completely inhibit Sulfolobus metallicus mixed Fe(II) and tetrathionate oxidation is 50 mg L À1 (0.5 mM; Dopson et al, 2006). The MIC of fluoride at pH 2.5 to Fe(II) oxidation was 0.8 and 2.0 mM at 6 and 228C, respectively, compared to 0.5 mM for both tetrathionate and thiosulfate utilization at both temperatures (Supplemental Table II).…”
