(a) Co-culture experiments of M. aeruginosa PCC7806 with seven genera, Rhizobium sp. MK23 apparently promoted the growth of M. aeruginosa PCC7806 for 7 days. **p < 0.05. (b) M. aeruginosa NIES-298 grew faster with Rhizobium sp. MK23. The M. aeruginosa NIES-298 culture and co-culture started degrading on 23 and 26, repectively. (c) Rhizobium sp. MK23 in co-culture grew at a density of 1014 cells/ml in 30 days. (d) Addition of catalase promoted the growth of M. aeruginosa PCC7806 for 4 days.
