珊瑚被大量的微生物定植,当珊瑚面临导致漂白的氧化应激时,它们的多样性对珊瑚的健康和恢复力起着重要作用。在目前的研究中,我们检查了从五种不同珊瑚物种中分离出的238种细菌(Acroporahyacinthus,Damicornis,波达巴甲壳纲,Poriteslobata,和Pavonavenosa)从卡瓦拉蒂的珊瑚礁生态系统中收集,Lakshadweep群岛,印度。我们发现细菌如嗜冷杆菌属。,Halomonassp.,Kushneriasp.,葡萄球菌。,Bacillussp.,短杆菌属。,柠檬酸杆菌sp.,和Salinicolasp.通常存在于珊瑚中。另一方面,Qipengyuaniasp.,Faucicolasp.,Marihabitanssp.,Azomonassp.,Atlantibactersp.,雪松sp.,Krasalinikoviellasp.,和Aidingimonassp.以前没有从珊瑚报告。在细菌分离物中,大量显示出高水平的生物膜形成(118),紫外线吸收(119),和黑色素产生(127)。考虑到这些属性,我们已经确定了来自Halomonas属的七个细菌的组合。,嗜冷杆菌sp.,Krasalinikoviellasp.,和微球菌。作为保护珊瑚免受氧化应激的潜在益生菌联盟。总的来说,这项研究提供了对珊瑚微生物组的有价值的见解,并为基于微生物组的干预措施开辟了可能性,以保护这些关键生态系统,面对全球环境挑战。
Corals are colonized by a plethora of microorganisms, and their diversity plays a significant role in the health and resilience of corals when they face oxidative stress leading to bleaching. In the current study, we examined 238 bacteria isolated from five different
coral species (Acropora hyacinthus, Pocillopora damicornis, Podabacea crustacea, Porites lobata, and Pavona venosa) collected from the
coral reef ecosystems of Kavaratti, Lakshadweep Islands, India. We found that bacteria such as Psychrobacter sp., Halomonas sp., Kushneria sp., Staphylococcus sp., Bacillus sp., Brachybacterium sp., Citrobacter sp., and Salinicola sp. were commonly present in the corals. On the other hand, Qipengyuania sp., Faucicola sp., Marihabitans sp., Azomonas sp., Atlantibacter sp., Cedecea sp., Krasalinikoviella sp., and Aidingimonas sp. were not previously reported from the corals. Among the bacterial isolates, a significant number showed high levels of biofilm formation (118), UV absorption (119), and melanin production (127). Considering these properties, we have identified a combination of seven bacteria from the genera Halomonas sp., Psychrobacter sp., Krasalinikoviella sp., and Micrococcus sp. as a potential probiotic consortium for protecting corals from oxidative stress. Overall, this study provides valuable insights into the
coral microbiome and opens up possibilities for microbiome-based interventions to protect these crucial ecosystems in the face of global environmental challenges.
