BACTERIA - 'ECOLOGISTS'
After several prolonged expeditions to various regions of World Ocean a
team of scientists headed by Corresponding Member of the USSR Academy of
Scinces IosifGitelzon conducted a thoreugh research into sea bacteria's ability to
luminesce. Of all the variety of luminescent microorganisms only luminescent
bacteria can be cultivated in laboratories and on an industrial soale producing an
unlimited amount of biomass. It turned out that the bacteria's bioluminescence
reaction can become an efficient test.
If a bacterium is luminescent, that means it is alive and its environment bas
none of the detrimental impurities. If such impurities emerge, the bacterium
stops luminescing and dies. According to scientists, the bacteria's sensitive
bioluminescence reaction to outside factors will make it possible to use micro-
organisms as test objects. Even maximum infinitesimal admixtures in the
atmosphere or water reservoirs are revealed by them immediately. But it Is not
only cells that are used as test objects. The luminescence system isolated from
them can be widely employed and is being employed for the microquantity
measurement of a number of ferments, substartes and inhibitors due to the great
effectiveness of the transformation of chemical bonds' energy into light.
To this effect biophysicists have elaborated a series of bieluminometers.
Every Instrument la adjusted for conducting certain research work in biochemistry,
medicine, microbiology, toxicology, and environmental protection..
This scientific and technological innovation has won several diplomas and
medals at Soviet and foreign exhibitions. Along with a computer that analyzes the
results of research and displays them in concrete indicators, the bioluminometers
show high efficiency. Рог example in medical work when it is necessary to ana-
lyze the inhibitors of human blood's proteases. It is known that the traditional
chemical analysis in polyclinics takes a long time. At the same time the ferments
of a bioluminometer carry it out in the space of a few minutes answering the
questions posed with great precision. Such a diagnostics makes it possible to
reveal the signs and trace the dynamics of diseases already at an early stage.
