Fig. 1From: Novel method to achieve crystallinity of calcite by Bacillus subtilis in coupled and non-coupled calcium-carbon sourcesCultures of B. subtilis and mineralized cell colonies formed in coupled and non-coupled calcium-carbon sources media. Images show stereoscopic view of plates and metallographic micrographs of recovered composites from a GLY, b GLC, c LAC, and d ACE media. Scale bars: 1 mm (black); 100 μm (white)Back to article page
