A method for separating genes from viruses existing in hydrosphere in an intact state, a method for fractionating thus separated genes, and a method for analyzing thus fractionated genes.
摘要:
There is disclosed a method for producing 3,4-dihydroxyphthalic acid, comprising treating phthalic acid with a product which is obtained by treating the cell membrane fraction of microorganism bacterial bodies capable of converting phthalic acid to 3,4-dihydroxyphthalic acid with a condensate of polyethylene oxide with a higher alcohol, thereby converting the phthalic acid to 3,4-dihydroxyphthalic acid. According to the method, only 3,4-dihydroxyphthalic acid, which is an intermediary metabolite, can be produced efficiently in a process of biodegrading phthalic acid with a microorganism.
摘要:
Microorganisms of a species selected from the group consisting of the specific species belonging to genus Nocardia, genus Pseudomonas, genus Brevibacterium and genus Corynebacterium, when cultured in a culture medium containing a phthalic acid ester as a carbon source, assimilate the phthalic acid ester and decompose it into carbon dioxide gas and water.
