RESEARCH PAPER ON BIOLOGICAL ACTIVITY OF ACTINOMYCETES ................ ABSTRACT: The microorganisms are ubiquitous in nature. They are found in probably every environmental condition present on earth. Actinomycetes were originally considered to be an intermediate group between bacteria and fungi but now are recognized as prokaryotic organisms with high G+C (>55%) content in their DNA. Our project aim is to evaluate some biological activities of Actinomycetes like:

1 Introduction 1.1 DEFINING POLYMERS Polymers are materials of very high molecular weight that are found to have multifarious applications in our modern society. They usually consist of several structural units bound together by covalent bonds [1‚2]. For example‚ polyethylene is a long-chain polymer and is represented by ÀCH2 CH2 CH2 À or ½ÀCH2 CH2 Àn ð1:1:1Þ where the structural (or repeat) unit is ÀCH2ÀCH2À and n represents the chain length of the polymer. Polymers are

CHAPTER ONE 1.0 INTRODUCTION Natural rubber is produced by over 2000 plants species and its main constituent is poly (cis-I‚4-isoprene).a highly unsaturated hydrocarbon. Since 1914 there have been efforts to investigate microbial rubber degradation: However‚ only recently have the first proteins involved in this process have been identified and characterized and have the corresponding genes cloned. Analysis of the degradation product of natural rubber and synthetic rubbers isolated from various
