searching for gene sequences, automated

you can download ncbi database into your computer, install command line blast and do your search in you computer. You can have as many sequences as your processor tolerate. alternatively you can create an account in BIOPORTAL OSLO and use their cluster for blasting. ...

Microbiology help in identifying Gram + rod for my unknown

Why you guys perform such amount of time consuming tests? Simply amplify 16S rDNA, sequence it and compare with the database via BLAST tool at NCBI website....

Unknown Organism

amplify 16S rDNA by using universal primer pair and sequence it. Then use the blast tool at NCBI and compare your sequence with the database...and you will know better than from performing these bacteriological tests.
