Hersch Posted October 2, 2008 Share Posted October 2, 2008 when enriching to recover injured salmonella cells from food samples using RV and MKKTn broths, why are they incubated 24 hrs/37 degrees? is this because some strains are able to grow at 47 degrees and 24 hrs gives sufficient time to recover enough cells for detection? or is there an ingredient in the media that requires 24 hours? cheers Link to comment Share on other sites More sharing options...
CharonY Posted October 6, 2008 Share Posted October 6, 2008 The additional incubation at 37 (not 47!) is for enrichment. Link to comment Share on other sites More sharing options...
