摘要:

有害赤潮对海洋生态环境和沿海经济危害巨大,如何安全、有效地治理有害赤潮非常重要。文章考察了几种常见芽孢杆菌对近海典型赤潮生物——东海原甲藻(Prorocentrum donghaiense)的去除作用,发现解淀粉芽孢杆菌(Bacillus amyloliquefaciens)对其去除作用最强。进一步考察解淀粉芽孢杆菌对不同赤潮生物的去除作用,发现该芽孢杆菌对米氏凯伦藻(Karenia mikimotoi)和赤潮异弯藻(Heterosigma akashiwo)的去除作用高于东海原甲藻。在此基础上,将解淀粉芽孢杆菌与高岭土复合,研究了微生物复合粘土对典型赤潮生物的去除效果。结果表明,解淀粉芽孢杆菌与高岭土复合后,能够有效促进该菌的生长,进而提升了其对赤潮生物的去除能力。文章对芽孢杆菌及其复合粘土去除赤潮生物的机制进行了分析和探讨,为进一步发展和优化改性粘土治理赤潮技术体系提供了重要参考。

Abstract:

Harmful red tides cause serious damage to the marine ecosystem and marine economy.It is very important to seek effective and safe technology to control harmful red tides.The removal efficiency of Bacillus and microbial modified clay on typical red tide organisms was studied.Results show that Bacillus amyloliquefaciens had the highest removal efficiency on Prorocentrum donghaiense among several common Bacillus.B.amyloliquefaciens had a higher removal efficiency on Karenia mikimotoi and Heterosigma akashiwo than P.donghaiense. It was found that kaolin could effectively promote the growth of bacteria,thereby enhancing the ability to remove red tide organisms.The mechanism of algae removal by Bacillus and microbial modified clay was discussed.This study provided an important reference for further development and optimization of red tide control technology with modified clay.

Key words: Bacillus red tide organisms red tide control technology microbial modified clay
