Effects of Aeration, Molasses, Kelp, Compost Type, And Carrot Juice on the Growth of Escherichia Coli in Compost Teas

From: Compost Science & Utilization | Date: January 1, 2006| Author: | Copyright information

Growth of a nonpathogenic E. coli strain (K12- MG1655, ATCC 700926) in aerated and nonaerated compost teas containing molasses, kelp and carrot juice was examined. Teas were prepared using four different compost types that had undetectable levels of indigenous E. coli. Three of the composts were produced by turn pile windrow composting method using dairy, swine and horse manure as feedstock, while the fourth, a vermicompost, was produced by feeding separated dairy solids to worms Eisenia feotida. Molasses and kelp enhanced the growth of E. coli in inoculated teas and the E. coli density was ...
