| Outline of Final Research Achievements |
In this study, we introduced an improved in situ DNA-HCR protocol (quickHCR-FISH) with higher sensitivity, and the amplification time was accelerated to only 15 min by using a dextran sulfate and blocking reagent containing amplification buffer, compared with 2 h in the original protocol. Finally, quickHCR-FISH was applied to marine bacteria in seawater and sediment samples for checking applicability of environmental microorganisms. The detection rates of marine bacteria after quickHCR-FISH were almost the same as after CARD-FISH. This newly developed protocol can be an attractive alternative to CARD-FISH for the detection of microorganisms in environmental context.
