Magnesium chloride and magnesium sulfate are tightly bound together into one inorganic compound in water. In the present invention, the substance is named siblesin (registered trademark). The substance is not a mere mixture but is a substance having functions beyond human comprehension. As a result, the substance is highly effective against viral colds and seasonal infections caused by influenza virus, coronavirus, rotavirus, and so on. In particular, the substance is a specific medicine for ALS, which is an intractable disease.

A method of separating oxygen from a body of water includes providing a colony of denitrifying bacteria submerged in the body of water. The colony of denitrifying bacteria can be used to convert at least a portion of nitrogen oxides present in the body of water to nitrogen gas. The method can also include collecting the nitrogen gas and bubbling the nitrogen gas through a portion of water from the body of water to remove dissolved oxygen from the portion of water. This can form a mixture of the nitrogen gas and oxygen gas.

A method of generating hydrogen gas includes providing a colony of sulfur-reducing bacteria and a colony of sulfur-oxidizing bacteria. The colonies can be submerged in a body of water. The colony of sulfur-reducing bacteria can be used to convert at least a portion of sulfates present in the body of water to hydrogen sulfide. The colony of sulfur-oxidizing bacteria can be used to convert the hydrogen sulfide to sulfuric acid. The sulfuric acid can react with manganese to produce hydrogen gas and manganese sulfate.

A recovery system for preparing magnesium sulfate from sulfuric acid waste solution is disclosed. The system comprises a reactor configured to remove hydrogen peroxide from the sulfuric acid waste solution and to promote a reaction between the sulfuric acid waste solution and a magnesium-based neutralizing agent to form a magnesium sulfate solution, a crystallization device configured to cool the magnesium sulfate solution and continuously crystallize magnesium sulfate crystals and a crystallization mother liquor, a dewatering device configured to separate the crystallization mother liquor from the magnesium sulfate crystals, and a drying device configured to obtain magnesium sulfate hydrates containing 0 to 7 molecules of crystalline water by controlling a drying temperature. A method for preparing magnesium sulfate using the recovery system is also disclosed.

A forest fire retardant composition contains a retardant compound that includes a halide salt, a non-halide salt, a metal oxide, a metal hydroxide, a sulfate salt, or combinations thereof. The forest fire retardant composition may include at least one anhydrous salt and at least one hydrate salt. The sulfate salt may be magnesium sulfate. The magnesium sulfate hydrate has a formula MgSO.sub.4(H.sub.2O).sub.x, where x is about 1 to about 11. For example, x may be equal to at least one of 1, 2, 3, 4, 5, 6, 7, 9, 10 or 11. The composition may be in the form of a dry concentrate, a liquid concentrate, or a final diluted product. The final diluted product is effective in suppressing, retarding, and controlling forest fires while exhibiting corrosion resistance and low toxicity.
