| 1. | It is the appropriate time to add the organic algaecides at the prophase of logarithmic phase
有机除藻剂对棕囊藻赤潮最佳投药期是其对数生长期的前期。 |
| 2. | Besides , it has a good efficiency using pvp - i to remove p . globosa red tide at the prophase of logarithmic phase
Pvp - i在棕囊藻生长指数期前期具有良好的除藻效果。 |
| 3. | Growth curve of y11 showed the logarithmic phase began from 7 hr and stationary phase began from about 18 hr . 20hr was consided as the optimal culture time for y11
生长曲线结果表明菌体液体培养7小时进入对数期， 18小时左右进入稳定期，因此初步确定菌体培养时间为20小时。 |
| 4. | In nitrogen - free medium , the logarithmic phase of the strain w12 was about 13 - 48 h . in logarithmic period its doubling time was 2 - 4 h in nitrogen - free medium , 0 . 9 - lh when enough nk
在无氮培养基上该菌在13h后进入对数生长期，并持续至48 52h ，这期间其生长代时为2 - 4h ，有氮培养基上为0 . 9 - 1h 。 |
| 5. | We used several organic algaecides to remove the phaeocystis globosa red tide . the results showed that povidone - iodine can release iodine slowly to kill and control the p . globosa red tide . the minimum used levels are 30mg / l if we added the povidone - iodine algaecide at the prophase of logarithmic phase
本文研究了缓释除藻剂碘伏对棕囊藻的去除作用，发现碘伏有一定的除藻能力，在棕囊藻指数生长期前期加入碘伏，最低有效除藻浓度为30mg / l 。 |
