Abstract
The present invention relates to compositions and methods to identify novel bacteria and metabolites derived therefrom. More specifically, the invention describes a novel method to isolate bacteria producing metabolites of interest from environmental samples. Particularly, the invention discloses a method to select rare antibiotic producing bacteria. The invention can be used from any sample and allows the isolation of bacteria having e.g., pharmaceutical or agrochemical interest.
Claims22
1-22. (canceled)
A method to identify or isolate a metabolite-producing bacterium, the method comprising:
- a) providing a sample comprising uncharacterized bacteria;
- b) subjecting the sample to a repeated irradiation treatment;
- c) identifying or isolating a living or growing bacterium from said treated sample;
- and
- d) selecting a bacterium of step c) which produces the metabolite.
A method to identify or isolate a bacterium which produces an antibiotic or a bacteriostatic-compound, the method comprising:
- a) providing a sample comprising uncharacterized bacteria;
- b) subjecting the sample to a repeated irradiation treatment;
- c) identifying or isolating living or growing bacteria from said treated sample;
- and
- d) exposing identified or isolated bacteria of step c), or an extract thereof, to a reference bacterial strain and identifying or isolating a bacterium which exhibits an antibiotic or bacteriostatic activity.
