11.   Small and undetectable numbers of sulphate reducing bacteria may have been present, unable to increase rapidly enough to be detected during the short period of this study.

12.   Sulphate feeding allows growth of sulphate reducing bacteria which then may inhibit methanogenic bacterial by substrate competition.

13.   An important alternative is the reduction of sulphate by sulphate reducing bacteria.

14.   People who harbour sulphate reducing bacteria in their large bowel have higher levels of sulphide in their faeces than methanogenic subjects.

15.   Because mucin structure and production varies between individuals, there may possibly be a genetic predisposition to the acquisition of sulphate reducing bacteria.

16.   We have shown that ulcerative colitis patients have a very high carriage rate of sulphate reducing bacteria and raised sulphide values in faeces.

17.   Because of the known toxicity of sulphide in the gut we suggest that the role of sulphate reducing bacteria in the pathogenesis of colonic diseases warrants further investigation.

18.   At that cold a temperature, the bacteria are reduced to non-detectable levels, yet the oyster retains its fresh flavor.

19.   That equipment would include either a jet mill or a spray dryer, each of which can be used to reduce bacteria into ultra-fine, inhalable powder.

20.   Dentists have long encouraged patients to brush their tongues to reduce bacteria.
