An algicidal bacterium DHQ25 involved its effects on photosynthesis in Alexandrium tamarense

【摘要】：正Harmful Algal Blooms(HABs) have been occurring worldwide in recent years. With its great damage to marine ecosystems and resources,HABs become a global problem to be solved.Interaction between bacteria and HABs species,which is considered regulating both the population dynamics and toxin production of algae,has received much attention.Many marine bacteria have been isolated with high algicidal activities.However,nearly no studies focus on the photosynthesis damage of algal cells caused by biotic factors,especially bacteria. A marine algicidal bacterium,Vibrio DHO25.with indirect alsicidal activitv
