Process for the removal of calcium ions from the brine by marine cyanobacteria

摘要

This invention relates to new use of marine cyano bacterium Lyngbya, Oscillatoria, Sprulina, Anabaena and Synechocystis being deposited with ATCC having accession no ______ for the removal of calcium ions from sea-brine and sub-soil brine having density range 10 to 25.5° Be', said use comprising culturing the cyanobacteria, inoculating the said cyanobacteria culture to raw brine of 10 to 25.5° Be', filtering the resultant mixture to obtain a bring having less calcium and to separate the cyanobacteria which can be reused if desired.
