You are indeed correct. There are sequence scanning methods out there
that by performing the G and T ladders onboth strands of a 16s RT-PCR
product, you essentially get sequence information. This of course is of
little use for direct ID of a biofilm organism, but the scanning method
greatly simplifies the tracing of the organism from apoint source to a
potential contamination site.
