ABSTRACT
The lineage-Actinobacteria class nov.comprises organisms with a DNA base composition which generally is above 50% G+C (with a few exceptions).We set up a method that has been used in isolating Actinobacteria and Actinomycetes. We added 25?g/mL Nalidixic acid and 25?g/mL Aztreonam into isolation media to inhibit the other bacteria and 20?g/mL Benlete to inhibit fungi.We used fluorescent in situ hybridization to identi 1fy Actinobacteria. Using the four probes,PA-1,PA-2,PHGC and PNHGC,we made the identification on the 31 strains of the 56 gram-positive bacteria randomly selected and got 22 positive results,6 negative results and 3 ambiguous results.It was showed that the results of G+C content determination and FISH method were identical.Among 31 strain,there were 24 strains of Actinobacteria,the rate was 77.4%.This proved the isolation and FISH identification methods were effective and reliable.
