| 摘 要： | 研究了沙雷氏菌的天然产物灵菌红素对引起海洋赤潮和淡水水华的有害藻类的除藻活性和光解性质.结果表明,5.0μg/mL灵菌红素能够在24h内将新月菱形藻、中肋骨条藻、水华鱼腥藻和微小平列藻培养液中的藻类全部杀死,除藻活性高达100%.5.0μg/mL灵菌红素在30000lx光强下36h完全分解,不会给自然环境带来二次污染. |
| 关 键 词： | 灵菌红素 除藻 赤潮 水华 光解 |

| Abstract: | Prodigiosin (PG),a secondary metabolite (red pigment) produced by Serratia marcescens and other bacteria,possesses a lot of bioactivity. However,its algicidal effect was not researched in detail. The algicidal activity of prodigiosin against harmful algae,causing red tide and fresh water bloom,and its light decomposition were studied. The algicidal concentration of prodigiosin for completely killing harmful algae in 24 hours including Nitzschia closterium,Skeletonema costatum,Anabena flosaquae and Merismope... |
| Keywords: | prodigiosin algicidal effect red tide water blooms photodecomposition |
