Abstract

This invention discloses an Acinetobacter bacillus with algicidal ability and its application, relating to the fields of microbial and environmental organic pollutant remediation technology. The Acinetobacter bacillus with algicidal ability is deposited at the Guangdong Provincial Microbial Culture Collection Center, with accession number GDMCC NO.65654. The 16S rDNA nucleotide sequence of Acinetobacter bacillus is shown in SEQ ID NO:7, and it is applied to the control of cyanobacterial blooms. This invention involves extracting extracellular culture of *Strombocytosporum* and culturing it on beef extract peptone solid medium. Single colonies are then extracted from the culture product, preserved, and inoculated into beef extract peptone liquid medium for further culturing. The bacteria isolated from the culture product are then amplified by PCR using specific primer pairs. The amplified products are sequenced and compared to identify the bacteria as Acinetobacter bacillus with algicidal ability, which can effectively inhibit cyanobacterial growth and has the advantages of being environmentally friendly, low-cost, and having significant algicidal control effects.
