Method of commercial production of aqueous sargassum seaweed extract concentrate and biostimulant products

A method of producing an extract from a high protein biomass for use as a biostimulant, comprising:

• a. harvesting high protein biomass;
• b. adding around 30 kg of the high protein biomass to around 500 ml-3785 ml of a solution comprising 25 wt. % acetic acid in 5 gallons of water;
• c. rinsing the high protein biomass for about 15 minutes to remove impurities until the salt content of the high protein biomass is about 4-7.5 parts per trillion and the electrical conductivity is around 9-12.61 mS/cm;
• d. drying the rinsed high protein biomass at a temperature of around 80-140 degrees Fahrenheit for 8-24 hours;
• e. placing the dried high protein biomass into a tank containing water comprising about 15 wt. % citric acid that has been heated to around 60-65 degrees Celsius in the ratio of around 1-100 parts seaweed:
• 2-40 parts of the heated water solution by weight;
• f. thereafter adding a mixture of one or more of sugar cane extract, 80% ethanol alcohol and molasses to the heated water solution at the rate of 1-4 parts per each part of dried high protein biomass by weight;
• g. thereafter adding yeast (Schizosaccharomyces pombe) at 10 grams per part of the dried high protein biomass by weight;
• h. thereafter allowing the heated water solution with the high protein biomass to cool to room temperature and stand in a covered container for about 7 to 45 days whereby anaerobic digestion takes place;
• i. thereafter removing the solid high protein biomass from the tank;
• j. thereafter adjusting the high protein biomass extract remaining in the tank to a pH of about 7.4-9;
• and
• k. thereafter aerating the high protein biomass extract for about 2 to 8 hours,
• wherein the arsenic level in the high protein biomass extract is about 1.32-15 mg/l, wherein further the cadmium level in the seaweed extract is about 0.005-5 mg/l, wherein the lead level in the high protein biomass extract is about 0.2-12 mg/l, wherein the mercury level in the high protein biomass extract is about 0.00002-2 mg/l, and wherein the pH of the high protein biomass extract is about pH is:
• 7.4-9.
