Calcium effect on microbial activity and biomass aggregation during anaerobic digestion at high salinity
The potential effect of different Ca 2+ additions (150, 300, 450, 600 and 1000 mg/L) on
microbial activity and aggregation, during anaerobic digestion at moderate (8 g/L Na+) and
high salinity (20 g/L Na+) has been investigated. Batch tests were carried out in duplicate
serum bottles and operated for 30 days at 37° C. At 8 g/L Na+, methanogenic activity and
protein degradation were comparable from 150 to 450 mg/L Ca 2+, and a significant
inhibition was only observed at a Ca 2+ concentration of 1000 mg/L. In contrast, at 20 g/L …
