Dear Harirchi, 

There are a no of test available for gram positive and negative bacteria, according to your requirement and availability of laboratory you can choose e.g. Coagulase test

Catalase test, Citrate test, DNase test, Hippurate test, Hydrogen sulfide production

Indole test, Lecithinase test, Mixed acid fermentation, Oxidase test, Urease test, Voges-Proskauer (VP) test

Thanks Dear Rao,

Do you know what modification is needed for high temperature to carry out these tests?

and Is OF test routine for this group of bacteria?

Dear Harirchi, 

For this complete information you need to review the literature once again. 

Look at the papers that contain the descriptions of new thermophilic bacterial species. See the attached file---"thermophiles.txt"---which contains all bacterial species from "A" to "T" described in the papers that contain "thermophilic" in the title (so, beware---not all the listed species will be thermophiles). For the links to the papers, see "Bacteria I. Names" . . .

Book Bacteria I. Taxonomy: Genera and Species

Dear Martin,

Thanks. I did as you referred and I searched IJSEM. I found useful but not complete information. Anyway, thanks again
