back to phase two of our experiment . the samples were kept in the incubator for over 48 hours and a good growth is expected.


samples taken out and what we need: funnels, filter papers, growth media "food", and sample


funnel fixed in the "membrane filtration system"



take and fix the filter paper to the system


add sample and run the device.


remove the filter paper and place it in the media
note: i used ENDO agar for "total coliform count" and S&B media for "fecal streptococci"


put the plates in the incubator and wait for 24 hours :)
