Abstract
Compositions comprising a plurality of yeast cells, wherein said plurality of yeast cells have been cultured in the presence of an alternating electric field having a specific frequency and a specific field strength for a period of time sufficient to substantially increase the capability of said plurality of yeast cells to suppress the growth of algae or decompose debris of algae. Also included are methods of making such compositions.
Claims16
A composition comprising a plurality of yeast cells, wherein said plurality of yeast cells are characterized by a substantial increase in their capability to suppress the growth of algae as a result of having been cultured in the presence of an alternating electric field having a frequency in the range of 6340 to 6380 MHz and a field strength in the range of 0.5 to 400 mV/cm, as compared to yeast cells not having been so cultured.
A composition comprising a plurality of yeast cells, wherein said plurality of yeast cells are characterized by a substantial increase in their capability to decompose debris of algae as a result of having been cultured in the presence of an alternating electric field having a frequency in the range of 4440 to 4470 MHz and a field strength in the range of 0.5 to 400 mV/cm, as compared to yeast cells not having been so cultured.
A method of preparing a yeast composition, comprising culturing a plurality of yeast cells in the presence of an alternating electric field having a frequency in the range of 6340 to 6380 MHZ and a field strength in the range of 0.5 to 400 mV/cm, wherein said plurality of yeast cells are characterized by a substantial increase in their capability to suppress the growth of algae as a result of said culturing as compared to yeast cells not having been so cultured.
A method preparing a yeast composition, comprising culturing a plurality of yeast cells in the presence of an alternating electric field having a frequency in the range of 4440 to 4470 MHZ and a field strength in The range of 0.5 to 400 mV/cm, wherein said plurality of yeast cells are characterized by a substantial increase in their capability to decompose debris of algae as a result of said culturing as compared to yeast cells not having been so cultured.
