Previous studies on Antarctic seawater have demonstrated the presence of significant numbers of bacteria, but their in situ activity has not been demonstrated. In order to demonstrate this hypothetical activity, a scheduled survey was conducted from January to February 1986 in a coastal area of Adelie Land. Seawater samples were collected in a selected station every day or every hour during a 17 hour period. Bacterial communities in each sample were studied by measuring direct and viable counts, frequency of dividing cells estimation, taxonomic analysis, and heterotrophic potential. Complementary studies used batch cultures with artificial nutrient supplements. The results clearly suggest a strong potential activity of the natural Antarctic bacterial microflora.
先前对南极海水的研究表明，其中存在大量细菌，但这些细菌的现场活动尚未得到证实。为了证明这种假设的活动，我们于 1986 年 1 月至 2 月在阿德利地沿海地区进行了一次预定调查。在 17 小时的时间内，每天或每小时在选定的站点采集海水样本。通过直接计数和活菌计数、分裂细胞频率估算、分类分析和异养潜能来研究每个样本中的细菌群落。补充研究使用了含有人工营养补充剂的批量培养。结果清楚地表明，天然南极细菌微生物区系具有很强的潜在活性。
