These strains were divided into musty or odorless group by crude culture experiments, and of these, only 2 strains were able to be isolated as an axenic culture. As the axenic strain produced musty odor in the culture with BG-11 medium, it has suggested that odor was due to metabolites in the growth of musty strain. The ability to produce odorous substance, however, was none or variable by different strains. In general, musty strains showed a tendency to grow slowly in comparison with odorless strains, and trichomeyellowing of the former was later than that of the latter. All the strains were presumed as species of Pseudanabaena by modern identification system of Rippka et al. who revised generic assignment by pure cultures. Filamentous materials were observed on the cell envelope of musty strains, but in detail further study in required., 水道貯水池より得た青緑細菌19株を用い,青緑細菌によるカビ臭の発生について検討し,次の結果を得た. 1) カビ臭は純離株ⅩⅦでは全く青緑細菌自身の臭気であることを確認した. 2) 供試株はすべてがPseudanabaena spp.に属し,これらはカビ臭発臭性のものと非発臭性が含まれた. 3) カビ臭発臭株の細胞周縁には電子顕微鏡によって線維状構造物が観察された., 長崎大学水産学部研究報告, v.52, pp.47-53; 1982}, pages = {47--53}, title = {呉市の水道貯水池から分離した青緑細菌Pseudanabaena spp.によるカビ臭発生}, volume = {52}, year = {1982} }
