The biotechnological potential for agricultural applications in the soil in the thawing process on Whalers Bay, Deception Island, Antarctica was evaluated using a metagenomic approach through high-throughput sequencing. Approximately 22.70% of the sequences were affiliated to the phyla of the Bacteria dominion, followed by 0.26% to the Eukarya. Proteobacteria (Bacteria) and Ascomycota (Fungi) were the most abundant phyla. Thirty-two and thirty-six bacterial and fungal genera associated with agricultural biotechnological applications were observed. Streptomyces and Pythium were the most abundant genera related to the Bacteria and Oomycota, respectively. The main agricultural application associated with bacteria was nitrogen affixation; in contrast for fungi, was associated with phytopathogenic capabilities. The present study showed the need to use metagenomic technology to understand the dynamics and possible metabolic pathways associated with the microbial communities present in the soil sample in the process of thawing recovered from the Antarctic continent, which presented potential application in processes of agro-industrial interest.
利用高通量测序的宏基因组学方法，评估了南极欺骗岛 Whalers Bay 土壤解冻过程中农业应用的生物技术潜力。大约 22.70%的序列与细菌域的门有关，其次是 0.26%的真核生物。变形菌门（细菌）和子囊菌门（真菌）是最丰富的门。观察到 32 个和 36 个与农业生物技术应用相关的细菌和真菌属。链霉菌和疫霉是与细菌和卵菌纲分别最相关的最丰富的属。与细菌相关的主要农业应用是氮固定；相比之下，真菌与植物病原能力有关。本研究表明，需要使用宏基因组学技术来了解与从南极大陆恢复的土壤样本中存在的微生物群落相关的动态和可能的代谢途径，这在农业工业感兴趣的过程中具有潜在的应用。
