The anaerobic bacteria occurring in paddy soils sampled from fields belonging to the Rice Research Station at Ohmagari in Akita Prefecture, Japan, were surveyed from May to November, 1974. Irregularly shaped rods predominated which were found to be gram-positive, strictly anaerobic, catalase-positive and not heat-resistant; populations were estimated at 10(5)--10(-7) cells/g dry soil throughout the entire survey period. On the basis of their morphological and physiological characteristics these bacteria were identified as Propionibacterium. Most strains belonged to P. lymphophilum and P. granulosum.
1974年5月至11月，对从日本秋田县大曲市水稻研究站所属田地采集的稻田土壤中存在的厌氧细菌进行了调查。不规则形状的杆菌占主导地位，发现它们革兰氏阳性、严格厌氧、过氧化氢酶阳性且不耐热；在整个调查期间，估计每克干土中的菌数为10⁵-10⁷个细胞。根据其形态和生理特征，这些细菌被鉴定为丙酸杆菌属。大多数菌株属于嗜淋巴丙酸杆菌和颗粒丙酸杆菌。
