ive done some research into the use of irradiation in decontaminating products of bacteria. Ive found that fruits when treated with UV light have the ability to build up resistance to the bacteria via the hormetic effect. Do you guys think it can work the other way around as well? can bacteria build up mechanisms to become resistant to the effects of UV?

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

thanks!

gday folks. Im looking to confirm S.aureus in a food sample and so far ive inoculated a GC broth (+), inoculated BPA from the positive GC broth and about to inoculate BHIB ready to perform a coagulase test. My question is what is the reason for inoculating BHIB prior to doing a coagulase test. thanks! hope that makes sense.. hersch
