Results and discussion

Any other information on results incl. tables

- Direct addition of test substance: None of the 28 strains (i.e.  excluding those identified in the present study) utilized  1,2,3,4-tetrahydronaphthalene.
- Addition of test substance via gas phase and via hydrophobic solvent:
  Arthrobacter A177 positive with both
  Corynebacterium C125 positive with both
  Nocardia S3 positive with both
  Pseudomonas A2 positive with gas phase addition
  other strains negative.
- Isolation of additional strains
  Acinetobacter T5 (gas phase method);
  Arthrobacter T2 (gas phase method);
  Arthrobacter T6 (solvent phase method);
  Moraxella T7 (solvent phase method);
Thus eight strains of bacteria utilizing 1,2,3,4-tetrahydronaphthalene as  sole source of carbon and energy have been obtained.

Applicant's summary and conclusion

Conclusions:

Eight strains of bacteria were able to growth in tetrahydronaphthalene as sole source of carbon and energy.
These bacteria belong to the genera Acinetobacter, Arthrobacter, Moraxella

Executive summary:

Eight strains of bacteria were able to growth in tetrahydronaphthalene as sole source of carbon and energy. These bacteria belong to the genera Acinetobacter, Arthrobacter, Moraxella
