    • CHAPTER ONE - [ Total Page(s): 2 ]  INTRODUCTION   The development of multidrug resistance in pathogenic organisms is a continuous problem faced by currently used antibiotics (Baltz, 2007). Therefore, the availability of potent drug is becoming particularly an acute problem (Neu, 1992). In this scenario, microorganisms have been intensively screened from soil as a source of therapeutically important molecules over a half century (Fenical, 1993) however; the frequency of discovery of structurally new ...

      CHAPTER TWO - [ Total Page(s): 1 ]MATERIALS AND METHODS   STUDY AREA   The study area was in Nsukka, a local government area in Enugu state, situated in Nigeria. The temperature range was about 23-30oc. samples were taken from the environment of the university of Nigeria, Nsukka and Odenigbo street in Nsukka. COLLECTION OF SAMPLES   Two relative samples were collected during rainy season in the month of June and July from different locations; on the road paths of the un ... Continue reading---

         

      CHAPTER THREE - [ Total Page(s): 1 ]RESULTS 3.1. DISCUSSION   This study was focused on earthworm castings because earthworms redistributes organic matter within the soil, increase soil permeability and increase microbial activity by their burrowing and feeding activities (Syers & Springett, 2005). Hence, an effort had been made to explore the bacteria from earthworm castings for their antagonistic activity. A total of 12 bacteria species were isolated from earthworm casting, out of which 7 (58.33%) were isolated from ... Continue reading---

         

      CHAPTER FOUR - [ Total Page(s): 1 ]4.1. DISCUSSION The history of new drug discovery processes shows that novel skeletons have, in the majority of cases, come from natural sources (Bevan et al., 1995). This involves the screening of microorganisms and plant extracts, using a variety of models (Shadomy, 1987). In this scenario, it is important to screen bacteria from different unexplored habitats, which may prove to be the important sources of potent molecules. This study was focused on earthworm castings because earthworms red ... Continue reading---
