Abstract
A Effect on physiological metabolism of microorganism which irradiated by visible light of non-ionization radiation(12,000 Lux) was investigated. The microorganism used in this experiment was a Rhodospirillum rubrum KS-301 of chemosynthetic microorganism. Batch fermentation of glucose were implement, and based on the data resulted from the fermentation. First, physiological characteristic of microorganism which was not irradiated was investigated. As a result, the decrease of the residual quantity of the substance(5.03 g/L - 2.17 g/L) was increased with the quantity of the bacteria(1.08 g/L - 3.14 g/L)and the quantity of the hydrogenous production(0.186 g - 0.3 g) respectively. Second, physiological characteristic of microorganism which was irradiated was investigated. As a result, the decrease of the residual quantity of the substance(13.17 g/L - 5.2 g/L) was increased with the quantity of the bacteria(4.7 g/L - 10.57 g/L)and the quantity of the hydrogenous production(0.186 g - 0.3 g) respectively. As the physiological characteristic of microorganism which was irradiated by visible light of non-ionization radiation(12,000 Lux) was active with its life, but the cell damages irradiated by with gamma-ray, X-ray, electron-ray in ionization radiation were appeared at cell.
본 실험은 비 전리방사선인 가시광선을 조사한 미생물에서의 생리적 대사특징을 연구하였다. 이 실험에 사용된 미생물은 화학합성미생물인 Phodospirillum Rubrum KS-301이었다. glucose의 회분발효를 수행하였고 발효결과는 테이터의 기초가 되었다. 첫째, 비 전리방사선인 가시광선을 조사를 안 할 때의 잔류 glucose(기질량)량을 5.03 g/L -2.17 g/L로 감소하면은 균체량은 1.08 g/L - 3.14 g/L로 수소생성량은 0.02 g - 0.19 g로 증가 하였다. 둘째, 비 전리방사선인 가시광선을 조사 할 때의 잔류 glucose(기질량)을 13.17 g/L - 5.2 g/L로 감소하면은 균체량은 4.7 g/L - 10.57 g/L로 수소생성량은 0.186 g - 0.3 g로 증가 하였다. 이 실험결과를 종합해 볼 때 비 전리방사선인 가시광선을 조사한 미생물에서의 생리적 대사특정으로는 가시광선을 미생물에게 조사한 결과 생명의 활동이 활발하게 일어나고 있음을 알았고 그 반대로 다양한 연구논문에 따르면 감마선, 엑스선, 전자선을 조사한 미생물에서는 세포치사나 세포의 기능적, 형태학적 장해를 나타내었음을 알 수가 있었다.
