Researchers Fishing Pure Gold from Seawater LODI
May 16, 2016 · GERMANY – The sea is a gold mine depending on where you look. Normally one liter of sea water contains only a few billionths of a gram of gold. But now researchers have discovered from a bubbling spring on the Icelandic Reykjanes Peninsula. It contains gold whose concentration is half a million times higher than in normal seawater.

The term "marine microbe" covers a diversity of microorganisms, including Bacteria, Archaea, Eukaryota, and viruses. These organisms are exceedingly small—only 1/8000th the volume of a human cell and spanning about 1/100th the diameter of a human hair. Up to a million of them live in just one milliliter of seawater.

Seawater is water from a sea or ocean. On average, seawater in the world''s oceans has a salinity of approximately 3.5%, or 35 parts per thousand. This means that for every 1 litre (1000 mL) of seawater there are 35 grams of salts (mostly, but not entirely, sodium chloride) dissolved in it. Although a vast majority of seawater is found in oceans with salinity around 3.5%, seawater is not
