Ecological Studies on Microorganisms Producing Antimicrobial Agents from Different Soil Types.

摘要

ABSTRACT In the present study, a trial was done to find out the distribution of antimicrobial agent producing bacteria from different soil types collected from different regions of Egypt governorates. Physical and chemical properties of soil samples were determined and isolation of different bacterial colonies from different soil types was also carried out. All the isolated bacterial colonies were then screened for their antimicrobial activity against the human pathogenic bacteria (Gram negativ.
