Abstract: | The authors have demonstrated the biological nature of a process in which nitroester bonds are hydrolysed in the molecule of nitrocellulose. Pseudomonas fluorescens, strain 1/2, was isolated from a natural cenosis of microorganisms inhabiting active ooze, which was selected in a device for continuous cultivation by immobilisation on nitrocellulose fibers. The strain cleaves some nitro groups off the surface of nitrocellulose and the resultant nitrate ions are used in the process of assimilative reduction. |
