| biomineralization of carbonates by marinococcus albus and marinococcus halophilus isolated from the salar de atacama (chile). | we studied the precipitation of carbonates in 17 strains of moderately halophilic, gram-positive cocci belonging to two species: marinococcus halophilus and marinococcus albus, isolated from the salar de atacama (chile). they were cultivated in solid and liquid laboratory media for 42 days at salt concentrations (wt/vol) of 3%, 7.5%, 15%, and 20%. the bioliths precipitated were studied by x-ray diffraction and scanning electron microscopy. m. halophilus formed crystals at each of the salt concen ... | 1999 | 10387118 |
