Patent ID: 8658182

Claim:
A method of making a phytoplankton extract, the method comprising the steps of: i.) collecting seawater directly from a sea, wherein the seawater contains multiple species of single-cell phytoplankton ranging in size from 1 μm to 1000 μm; ii.) storing the seawater of step i.) in at least one tank; iii.) adding nutrients to the seawater of step ii.) to proliferate the multiple species of single-cell phytoplankton to a concentration of 50,000 to 5,000,000 single-cell phytoplankton per milliliter of seawater; iv.) circulating the seawater of step iii.); v.) mixing air with the seawater of step iv.); vi.) adding sodium hydroxide (NaOH) to the tank at ambient temperature to the seawater of step v.) until the seawater reaches a pH of about 10.5 to autolyze the multiple species of single-cell phytoplankton contained therein; vii.) collecting the autolyzed phytoplankton of step vi.) to obtain the phytoplankton extract, wherein the phytoplankton extract is an algae paste.
