Abstract

CLAY 'SLUDGE' AND GYPSUM MIXTURES EFFECT ON FECAL BACTERIAL IN ENVIROMENTAL SAMPLES**, Lillie Brannen and Dave Bachoon, Georgia College and State University, Milledgeville, GA 31061 Clay Ôsludge' from a water treatment plant and gypsum from a coal burning power plant were evaluated for their ability to inhibit the growth of fecal bacteria from cattle, pig, and goose. Flask containing clay and or gypsum were inoculated with E. coli and fecal bacteria from animals. The treatments were run in duplicate in a 250ml flask containing 200ml of 0.9 saline solution. After which, E. coli and was enumerated using IDEXX Collilert-18. This was done every two days for eight days. The clay Ôsludge'/ gypsum inhibited the E. coli growth more than the others, and the clay Ôsludge' inhibited growth second best. The gypsum and the autoclaved sand had the same rate of inhibition.
