TABLE 1 



The oxidation of elementary . nlfur at different reactions 

 Medium 6 without the KIIjP04 used as a basis 



rapidlj', with an abundant separation of sulfur. This separation 

 of sulfur from the thiosulfate as a result of the action of this 

 organism indicates its rather weak sulfur-oxidizing power. 

 When Th. thiooxidans is also present, the pelUcle is either not 

 formed at all, especially when the medium is acid, or, in alkaline
