Bacillus stearothermophilus was found in Icelandic soils. Of the 33 strains studied, only four grew at 25 C. Temperatures as high as 27 C in bare soil at a depth of 1 to 1.5 cm were measured at the collection site. However, to demonstrate growth the cultures had to be incubated for 3 weeks, and soil temperatures remained at 27 C only for shorter periods of time.
嗜热脂肪芽孢杆菌在冰岛土壤中被发现。在所研究的33个菌株中,只有4个能在25℃下生长。在采集地点,1至1.5厘米深度的裸土中测得温度高达27℃。然而,为了证明其生长,培养物必须孵育3周,而土壤温度仅在较短时间内保持在27℃。
