CHAPTER ONE 1.0 INTRODUCTION 1.1 Antimycobacterial Studies An Antimycobaterial is a substance that kills or inhibits the growth and activities of disease causing Mycobacteria (e.g.‚ Mycobacterium tuberculosis‚ Mycobacterium Leprae‚ etc) that are responsible for fatal diseases such as Tuberculosis and leprosy. Antimicrobacterials can either kill microbes (microbiocidal) or prevent the growth of microbes (microbiostatic) (Hannan et al.‚ 2011). Mycobacterium is a genius in the family of the Mycobacteriaceae

in 1910. By the mid of 1920s Rayon fibre was being used increasingly by the textile industry‚ not because of better quality but because of its low price. In 1931 American chemist Wallace Carothers first discovered nylon fibre. Unlike rayon and acetate which were derived from plant cellulose‚ nylon was produced completely from synthetic polymers. At that time he was working for Dupont. Dupont started commercial production of nylon in 1939.Although the first nylon product was toothbrush‚ it was not
