RESUMO
To rapidly and accurately enumerate total and specific microbes in aquatic samples, fluorescent in situ hybridization was combined with direct counting via direct immobilization of cells on a polymer-coated Nuclepore filter. The technique, named FISH-DC, achieved almost complete recovery of total cells and reproducibility of Psychrobacter pacificensis cells of deep-sea origin (error, ≤3%) in a mixed culture and in natural seawater. Target cells immobilized on the filter were also successfully enumerated after stringent 3-cycle hybridization and even after a 16-month preservation at −30°C.
