摘要

研究了从印度东海岸采集的12种珊瑚虫(4种柳珊瑚、5种软珊瑚和3种抗菌剂)对从污染铝板生物膜中分离的4种优势海洋污染菌的抑菌活性。在48个组合(12个珊瑚x 4个细菌)中,18个相互作用具有抗菌活性(37.5%)。这种活性在柳珊瑚中最为明显,在16次相互作用中有10次(62.5%)抑制细菌生长,而在软珊瑚中有5次(25%)抑制细菌生长,在抗病原菌中有3次(25%)抑制细菌生长。活性得分因使用的提取物和测试生物体的不同而不同,在抗病性药物中最高。4种细菌中,弧菌(2/12)最不敏感,黄杆菌(6/12)最不敏感。本文首次报道了抗菌菌落对海洋微污垢的抑菌作用。这一结果表明,珊瑚虫珊瑚中含有有效的防污剂,可用于开发防污技术。

Antibacterial activities of anthozoan corals on some marine microfoulers.

The antibacterial activities of twelve species of anthozoans (4 gorgonians, 5 soft corals and 3 antipatharians) collected off the east coast of India were assayed against four dominant marine fouling bacterial strains isolated from the biofilm of fouled aluminium panels. Of the 48 combinations (12 corals x 4 bacteria) eighteen interactions showed antibacterial activity (37.5%). Such activity was most apparent in gorgonians, which inhibited bacterial growth in ten out of sixteen interactions (62.5%) compared with that of five out of twenty interactions (25%) among soft corals and three out of twelve interactions (25%) among antipatharians. The activity scores varied with different extracts and test organisms used, and was highest in antipatharians. Among the four bacterial strains Vibrio sp. was the least sensitive (2/12) when compared with Flavobacterium sp. (6/12). This is the first report of antibacterial activities of antipatharian colonies against marine microfoulers. The results imply that anthozoan corals harbour potent agents which could be exploited for the development of antifouling technology.
