The blue‐green algae Microcystis aeruginosa and Phormidium tenue were grown in nutrient‐limited continuous cultures together mixed under various N:P supply ratios temperatures. Droop model accurately described the growth of these two algae. Competitive abilities for P N distinctively differed among In competition experiments, M. was superior competitor conditions low N: ratio high temperature, whereas P. : which corresponded to field observations algal community Lake Kasumigaura. Both...
mlrA is the only microcystin-degrading gene detected in Sphingomonas sp. MJ-PV. The has an extremely rare nucleotide sequence and homologous genes have not yet been discovered DNA database. We existence of a to new bacteria, MD-1 Y2. These strains possessed homologues, identities Y2 with corresponding MJ-PV exceeded 98% 84%, respectively. On other hand, was laboratory closely related spp. employing hemi-nested polymerase chain reaction detection using two primer sets. Although bacteria were...
