Isolation of Antibiotic Producing Microorganisms From Two Soil Samples of Phirangipuram,guntur

Abstract

Antibiotics are chemicals, that kill or inhibit the growth of bacteria and are used to treat bacterial infections. They are produced in nature by soil bacteria and fungi. Soil is the outer region of earth crust consisting of loose material. In this, soil samples from two areas were collected (vegetable dump area(A), street soil(B)) and analysed, different bacterial colonies from soil samples was formed and tested for antimicrobial activity. The isolated and subcultured strains showed permanent zones of inhibition. The inhibitory activity of the organism was checked against important microbial flora. In the present study a trail was done to find out a new antimicrobial agent, producing bacteria from soil samples collected from two places. conditions. The petriplates were marked as, sample A(A6, A7, A8and A9), sample B(B6, B7, B8 and B9).
