Physiological response of Microcystis aeruginosa to the extracellular substances from an Aeromonas sp.

摘要: Bio-control techniques, especially using ubiquitous algicidal bacteria, have the potential to remove harmful algae. Understanding mechanisms with regard bacterial effect on algal cells will facilitate development of biotechnology processes. In present study, Microcystis aeruginosa was exposed extracellular substances Aeromonas sp. strain FM, a previously isolated cyanobacterial growth inhibitor. The aim this study examine physiological responses M. different amounts from results showed that dehydrogenase activity and intracellular protein level were influenced by dosage substances. could enhance release polysaccharides aeruginosa. During treatment, superoxide dismutase malondialdehyde content increased in cells. On other hand, 1% 3% didn't cause microcystins short-time treatment (4 days). This provides clues understand mechanism indirect action bacteria towards
