Actinomycete flora of japanese soils

Actinomycete flora of Japanese soils

“…Therefore, comparison of the authors' result with those of other investigators is impossible, and so, the authors would like to compare these with the characteristics of upland soil reported in the previous paper (19 %, respectively. Each ratio in the paddy soil is fairly lower than that in upland-cultivated soil.…”

“…The actinomycete flora of different soil groups has been studied in the authors' laboratory and it was reported that each group has its own characteristic actinomycete flora (18,19,20). Following the previous part, in which actinomycete flora in paddy soils was described from morphological, cultural and biochemical points of view (20), the description will be made on the basis of antibiotic production in the present paper.…”

“…As shown in Table 3, actinomycete flora of pe,lt soil was compared with those of other soil groups (11,12) on the basis of genus. The most marked characteristics of peat soil.…”

“…The soil samples were collected in Bibni twice in July and October, whereas in Teshio IInel Shibetsu only onCe in September, respectively. Actinomycete floras Were examined by the method describeJ in the previolls papers (11,13).…”

“…In the previous paper (11), it was described that each soil group as well as each soil showed its own characteristic actinomycete flora and it was maintained throughout a year, though not without some seasonal change. On the other hand, in another paper (12), it was reported that the actinomycete flora of each soil group could be characterized also on the basis of biochemical characters.…”
