Polyphosphate (polyp) kinase was prepared from EDTA-lysozyme spheroplasts of a Salmonella minnesota rough mutant. The enzyme, purified about 8o-fold, was free of ATPase and polyp-degrading activity and contained neither nucleic acids nor polyp which might act as primer. Using this enzyme, 32P-labelled polyp was prepared from [?P]ATP. The polyp was identified by the action of degrading enzymes, ...

A bacterial strain Pseudomonas sp. a3 capable of degrading nitrobenzene, phenol, aniline, and other aromatics was isolated and characterized. When nitrobenzene was degraded, the release of NH(4) (+) was detected, but not of NO(2) (-). This result implied that nitrobenzene might have a partial reductive metabolic pathway in strain a3. However, aniline appeared as one of the metabolites during th...

Aspergillus terreus gave the overall best results in alpechin at approximately 80% concentration, degrading organic material by 53%, expressed as COD, and 67%, expressed as BOD. Degradation of the total phenol content, which included the great majority of phenolic compounds, reached 69%.

in this study, among the 21 diesel-degrading bacteria that were isolated from an oil-polluted area in fars (iran), 6 bacterial strains were tested for their capability to metabolize and grow on diesel oil by degrading its hydrocarbons content. the biochemical characteristics and 16s rrna sequence analysis of diesel-degrading bacteria showed that these strains were related to the genus pseudomon...

In the present study, bioprospecting aspects of endophytic bacteria, isolated from leaves of 5 mangroves and 2 salt-marsh plant species, were explored. In total, 104 bacterial isolates were isolated from the leaf samples of mangrove plants of Pichavaram, Tamil Nadu. Thirty six fast growing isolates were selected and screened for biological activities. Of 36 isolates, 28 (77%) showed antimicrobi...
