Identification of Phototrophic Bacterium T-20

광합성(光合成) 세균(細菌) T-20주(株)의 동정(同定)

Phototrophic bacteria T-20 investigated in the present report was isolated from Thailand oil, Cells of the bacterium were rod-shaped. measured $0.6{\sim}0.7{\mu}m$ wide, and $2.3{\mu}m$ long. A color of cell suspension was red, and the long wavelength absorption maxima of the bacteriochlorophyll measured in 870nm. Substrates utilized as carbon sources: citrate, aspirate, glutamate, and fructose: unique for this strain is the liquefaction of gelatine, Ubiquinone Q-8 was also found. Rhodocyclus gelatinosus, which was reported in Bergey's Manual of Systematics Bacteriology, was corresponded to T-20.

태국의 토양으로부터 분리한 젤라틴 분해능을 갖는 광합성세균 T-20주(株)는 직경이 $0.6{\sim}0.7{\mu}m$의 적색 간균으로써, Bacteriochlorophyll a의 흡수극대는 870nm이었고 또한, 퀴논종(種)은 UQ-8을 나타내었다. 유기 화합물로써 citrate, aspirate, glutamate, fractose 등을 이용하였다. 이상의 결과로부터 T-20주는 Bergey's Manual of Systematic Bacteriology(1989)에 기재된 Rhodocyclus gelatinosus와 일치한다.
