Microcosms were closed with butyl‐rubber stoppers, and four gas aliquots (25 ml) were sampled using a gas tight syringe (1000 series, gastight ®; hamilton, reno, nv, usa) within 3 h of enrichment using the same type of vial described above. Resulting overpressure in the vials was released by connecting the vial to a pipe ending in a water.
