The relationship between chemical structure and hydrogen 

 sulphide formation 



In order to study the relationship between the state of oxida- 

 tion of sulphur compounds and the ease with which they may 

 be attacked by bacteria with resulting hydrogen sulphide for- 

 mation, three compounds were selected. Sodium sulphate was 

 chosen as a representative inorganic sulphur compound in which
