Hi! I need to retrieve ALL the sequences of the microbiome of a specific organism (X. testudinaria). What do you think is the best way?

You would be better finding papers which have produced the data you're looking for and seeing where it has been uploaded (or if it hasn't, ask them for it).
There is a repository for microbiome data at http://qiita.microbio.me/ which you can download from but I don't know if they have your organism, and it's not the most easy to navigate.
Thanks Daniel. As I've just answered a.polo I am trying to run a Perl script that is almost working. If I don't manage to get the dataset I'll try QIITA.
Thanks a.polo88 but I've tried that way. The problem is that when I try a more focused search (http://www.ncbi.nlm.nih.gov/gquery/?term=xestospongia+testudinaria) I end up with a very limited number of sequences actually belonging to the microbiome.

OK if I have understood well the problem is that actually the studies are focused on the Human Microbiome project. and perhaps the lower number of sequences is due to no data for all of the organisms and reflect the few studies. perhaps a solution is test every of these sequence with a BLAST search.
There are still to many sequences to run each one on BLAST. I am trying to run a script on Perl that is almost working. I am managing to retrieve the sequences... i am just not managing to get them on a document. Thanks!

Most of the microbiome database I know are for H.sapiens. You can look for publications that pertain to your questions and see where the data exists online; or it may lead to a collaboration or a new experiment. Good luck! http://hmpdacc.org/reference_genomes/reference_genomes.php
Thanks QVINTVS_FABIVS_MAXIMVS. I don't need an actual database... 'just' the complete set of sequences of all of the microorganisms found in X. testudinaria. I've download the BLAST microbial 16S database through Perl. I'll start there.
