摘要:
A bacterium strain JM1 (FERM BP-5352) capable of degrading organic compounds without inducers is disclosed. Further, methods for degrading organic compounds and remedying an environment using the bacterium strain are also disclosed. The microorganism is brought into contact with the environment under conditions which stimulates the organism to degrade the organic compounds and thus, remedying the environment of pollutants. A kit and method for selectively detecting the strain expressing oxygenase from a sample containing strain J1 FERM BP-5102 is also disclosed. The latter strain expresses oxygenase when induced, however, strain JM1 FERM BP-5352 does not require induction. In addition, a process for obtaining strain JM1 FERM BP-5352 is also disclosed.
摘要:
An apparatus for degrading a pollutant to purify a medium containing a pollutant using a microorganism, which comprises a container in which a region containing a microorganism capable of degrading the pollutant is provided, wherein the container has the first opening for introducing the medium into the container and the second opening for draining the medium passed through the region containing the microorganism from the container, and in the container a region containing a functional material which releases a material required for degrading the pollutant by the microorganism is provided between the first opening and the region containing microorganism.
摘要:
A process for microbial remediation of soil polluted with a pollutant by introducing into the polluted soil a decomposing microorganism, a nutrient and/or an inducer necessary for the expression of a decomposing activity in the microorganism, wherein a coefficient of permeability of the polluted soil is controlled to be small and uniform so that the introduced substance may be uniformly distributed over a soil area to be remedied. Also a process for treating soil which comprises a step of controlling the coefficient of permeability of the soil so that a peak at the substantially smallest coefficient of permeability may comprise the largest percentage in the distribution of coefficient of permeability.
摘要:
An apparatus for soil remediation to remedy a soil contaminated with a pollutant less affecting the environment, which includes a soil borer having a rotatable drilling form or portion capable of agitating the soil, introducing into the soil at least one agent selected from the group consisting of a microorganism capable of degrading the pollutant, a nutrient for the microorganism and an inducer to make the microorganism express the pollutant-degrading activity, and measuring pollutant concentration in the soil.
摘要:
A method and apparatus for diffusing a treating agent into a medium, a method and apparatus for injecting a liquid into a medium, and a method of remedying soil. The method of diffusing a treating agent into a medium, comprises a step in which a solidified treating agent is scattered and diffused by the pressure of a gas resulting from a gas-generating agent.
摘要:
A neutron beam controlling apparatus includes a plurality of multilayered plate members, each having on one or both of its surfaces, one or more minute protruding portions. Each of the protruding portions is a long and narrow protrusion extending in an area-wise direction and having both an inclined surface that is inclined against the beam axis of neutron beam and serves as an incident plane or an outgoing plane for the neutron beam and a surface approximately normal to the plate member.
摘要:
A method for remedying an environment containing a pollutant using microorganisms comprising a step of injecting a liquid containing a microorganism which can decompose the pollutant into a predetermined site of the environment to be remedied, wherein a gas has been dissolved into or mixed with the liquid by applying a pressure higher than the pressure at the injection site and the liquid evolves the gas when injected into the predetermined site, and an apparatus which comprises a means for injecting a liquid containing a microorganism which can decompose a pollutant into a predetermined site of the environment, wherein the means injects the liquid in which a gas has been dissolved into or mixed with by applying a pressure higher than the pressure at the injection site, into the environment under a pressure so that the gas does not evolve from the liquid before injection.
摘要:
A process for remedying polluted soil which comprises the steps of injecting a liquid agent containing a microorganism into the polluted soil, and injecting a gas into a region wherein the water content of the soil became 0.6 or more times its saturation water content after the injection of the liquid agent. Using this method bioremediation of contaminated soil can be economically and efficiently carried out.
摘要:
Provided is a fluorometric analytical method for detecting chloride ion in a sample by quenching of fluorescence of a fluorescent dye, the fluorescent dye being one of 3,6-bis(dimethylamino)acridine and a derivative thereof of the formulae ##STR1## wherein R is alkyl having 1 to 30 carbon atoms, and X.sup.- is a halogen ion.
摘要:
A process for treating colored liquid comprises a step of contacting a colored liquid and functional water generated by electrolysis of a water solution of an electrolyte under light irradiation, to decolorize efficiently and stably to a low chromaticity.
