 note = {The authors dealt with the distribution and identification of luminous bacteria in seawater around the Ryukyu Island Arc. We sampled in every autumn, 1978-'80: in '78, 33 samples were collected from 50m, 100m, and 300m depth layers at 14 stations around the Miyako Island; in '79, 38 samples from 15 stations around the Amami-o-shima; and in '80, 52 samples from 24 stations in the west region of the northern Ryukyu Island Arc; all told 123 samples from 53 stations.
The luminous bacteria were detected in 32 samples (5 samples in '78, 6 in '79, and 21 in '80).
The number of samples containing luminous bacteria were more in 50-100m layers than in 300m layers. Luminescent bacteria were recovered at concentrations of 1 to 4 cells per ml, and 50 strains in all were isolated. On the 50 luminous bacterial isolates, 23 (46%) were Vibrio fischeri, 1
(2%) were Photobacterium phosphoreum, 13 (26%) were P.mandapamensis, 13 (25%) were Lucibacterium harveyi. In sampes of '78, L.harveyi was a major component. It was different from the composition of luminescent bacterial species in samples of '79 and '80. The species composition of
'79 was almost same as that of '80, that is, V.fischeri 59%, P.phosphoreum 3%, P.mandapamensis 25%, and L.harveyi 13%. Thus, the species composition of the luminous bacterial commucities may serve as the indicators of different condition in marine water masses., 著者らは,琉球島弧周辺海域の海水から発光細菌を計数,分離し,それらを同定して,菌種別分布を調べた。我々は,試料を1978年から'80年の各年秋季に採集した。すなわち,それは,'78年には宮古島近海の14定点の深度50m,100m,300m層から33の試料,'79年には奄美大島近海の15定点から38試料,'80年には北琉球島弧西方海域の24定点から52試料,合計53定点から123試料であった。発光細菌は,32試料('78年の5試料,'79年の6,そして'80年の21)から検出された。発光細菌が検出された試料の数は,300m層よりも50~100m層で多かった。それらの1ml当たり発光細菌細胞は,1~3個の濃度で見出され,50株が分離された。分離発光細菌50株の菌種組成は : Vibrio fischeriが23株(46%); Photobacterium phosphoreum,1(2%); P.mandapamensis,13(26%); Lucibacterium harveyi,13(26%)であった。'78年の試料では,L.harveyiが優占種であって,'79年と'80年の試料中の菌種組成とは異なっていた。後2者の菌種組成はほとんど同じで,それは,V.fischeri 59%,P.phosphoreum 3%,P.mandapamensis 25%,そしてL.harveyi 13%であった。これらの結果から発光細菌群の菌種組成は,その海域の海況や生物生産性の違いを表す指標として役に立つものと考えられる。},
