Survival of an Escherichia coli in a Sarawak Soil
Soil is a natural digestion system for animal wastes. However, land disposal sites and agricultural land pose serious threats to the quality of surface and groundwater. In this study, a clay loam, Semongok series, from Sarawak was inoculated with wild strain E. coli isolated from animal wastes. Resu...
