(Title) PROCESS FOR THE PREPARATION OF SULPHUR-CONTAINING HYDRO CARBON CHAINS ( ) PROCESS FOR THE PREPARATION OF SULPHUR-CONTAINlNG HYDROCARBON CHAINS, which consists in producing a fermentative action of two types of bacteria, lactic bacteria and bacteria of the genus Desulfovibrio, in a medium of soluble carbohydrates, to which culture medium sulphur is added in the form of salts or as elemental sulphur, the fermentation process being stopped at the point at which the proportion of sulphur-containing carbohydrate reaches its maximum, by means of alkalinization of the medium and subjecting the latter to a thermal shock at between 80 and 90.degree.C, the medium finally being acidified or neutralized. As a variant, sulphur is bound directly to carbohydrate molecules with a reaction time inversely proportional to the working pressures and temperatures. |
