“…Samples of the vapour in the head space of the vials were injected into the chromatograph and the displayed signals were adjusted with the data handling software of the chromatograph until the signals were a linear function of the amount of hydrogen sulfide injected. The displayed signals for the other sulfur compounds were considered to be the same as for hydrogen sulfide, and proportional to their number of sulfur atoms but independent of their chemical structures (18). All glasswares were treated in 1 M HCl and thoroughly rinsed in water before use.…”

In 12 species of Fusobacterium the following characteristics were studied; the desulfhydration of L-cysteine and L-methionine by resting cell suspensions, the formation of alpha-keto-acids from L-cysteine, D-cysteine and L-methionine by cell extracts, and the formation of hydrogen sulfide from L-cysteine, D-cysteine and L-cysteine by cell extracts separated by polyacrylamide gel electrophoresis. Multiple forms of L-cysteine desulfhydrase activity were found in most of the species. In some of them also D-cysteine desulfhydrase activity was demonstrated. Seven of the species had high L-methionine gamma-lyase activity. L-cysteine activity was present in 5 of the species.

“…Samples of the vapour in the head space of the vials were injeeted, and the ehromatograph was adjusted until the displayed signals were a linear function of the amount of sulfide in the vials. To determine the eoncentration of sulfide in the vapour of the vials, the eoncentration of sulfide in the liquid phase of the vials were determined with the method of Siegel (23), The displayed signals for the other sulfur compounds were considered to be the same as for hydrogen sulfide, and proportional to their number of sulfur atoms but independent of their chemical structures (17), Ali glasswares were treated in 1 M HCl and thoroughly rinsed in water before use. The syringes were rinsed with 0,1 M phosphoric acid after each injection.…”

Hydrogen sulfide is formed by the subgingival microbiotas of periodontal pockets. The capacity of these microbiotas to form various volatile sulfur compounds in human serum was studied. Bacterial samples from nine deep periodontal pockets were incubated for 7 days in human serum and the amounts of volatile sulfur compounds and the degradation of serum proteins were determined. Hydrogen sulfide was the predominant volatile sulfur compound, but also methyl mercaptan was formed in significant amounts. Only traces of dimethyl sulfide and dimethyl disulfide were detected. There was an extensive degradation of the serum proteins. In most of the reaction mixtures hydrogen sulfide reached highly toxic levels.

“…For any given burner design, the response of the FPD is critically dependent upon the ratio of hydrogen to air or oxygen flow rates, the type and flow rate of carrier gas and the temperature of the detector block [171][172][173][174][175][176]. With this burner and flow configuration interfering emissions from hydrocarbons occur mainly in the oxygen-rich flame regions close to the burner orifice, whereas sulfur and phosphorus emissions occur in the diffuse hydrogen-rich upper portions of the flame.…”
