Outline of Final Research Achievements |
Synechococcus leopoliensis CCAP1405/1 cannot grow on agar media although the strain can grow in liquid media. However, the strain can grow when co-cultured with heterotrophic bacteria, such as Bacillus subtilis 168, on agar media. Supply of sulfide in the cysteine biosynthesis pathway from B. subtilis 168 was suggested for the mechanism. Additionally, B. subtilis 168 determines whether or not to induce the growth of S. leopoliensis CCAP1405/1 depending on its environmental and own conditions.
