My understanding is that you are better off using newer k-mer based approaches as opposed to BLAST. I've had reasonable success with kraken, although the memory requirements are somewhat onerous. You also have to be extremely careful about removing contaminant (aka human) sequences as these tend to get misclassified.

Another option is kallisto (https://github.com/pachterlab/metakallisto) but I have yet to be able to even build a database due to memory constraints.
I will try. Can you gimme the Kraken link? Thanks.
