Zusammenfassung: | The invention relates to a process for cultivating seaweed possessing improved biological properties as well as to cosmetic, food industry and fodder supplementing compositions containing the thus-prepared seaweed. According to the process of the invention, the seaweed is cultivated by sterilizing a culture medium containing medicinal water, mineral water or thermal water of natural origin or a mixture thereof, optionally enriched by metal compounds up to a concentration of 10-2 mole/litre as related to each metal ion and up to a concentration of 10-1 mole/litre of fluorides, under a pressure of at most 10 bars (1000 kPa) at a temperature between 100.degree.C and 140.degree.C, then inoculating it with a pure seaweed culture, bubbling through the culture medium a sterile air flow containing 0.5 to 20% by volume of carbon dioxide at room temperature, separating the seaweed after a cultivation lasting 7 to 30 days at 0.degree.C to 80.degree.C, optionally working up the thus-obtained seaweed in a conventional physical or chemical manner and optionally reacting the worked up seaweed with metal compounds until reaching a concentration of at most 10-2 mole/kg related to each metal ion. |
