    摘要: A liquid-solid particle sepation process is disclosed, which is characterized by comprising the repetition of feeding waste solution containing fine solid particles to a membrane-type separator and feeding at least part of the solution concentrated with particles therefrom back to the membrane-type separator on one hand while providing the concentrated solution to a centrifugal separator on the other. The process exhibits that the permeability of the membrane can be kept almost as good as in the beginning of filtering operation.

    摘要: The method of isolating organic compound-degradable microorganisms included in this invention is characteristic in that microorganisms in the organic compound contaminated sample, for example an environment sample, are cultured in a carbon-free medium, at the same time, are contacted with organic compounds mainly as the gas phase, and selected by the tolerance to the organic compounds as the index. Also, the method for biodegradation of organic compounds is characteristic in that the microorganism thus isolated, for example, Komagatella brevis, is contacted with contaminated soil or contaminated underground water, and without the addition of additives or inducing substances for organic compounds decomposing enzymes, may effectively biodegrade the organic compounds in the environment.
