This book described the principle of microbial systematics and the polyphasic approach used to identify a novel actinobacterium from the family Nocardioidaceae. Actinobacteria represent a significant component of the microbial population in most soils including the mangrove region. Actinobacteria has been extremely useful to the pharmaceutical industry due to their seemingly unlimited capacity to produce secondary metabolites with diverse biological activities and chemical structures. The novel actinobacterial strain, designated MUSC 201T was isolated from a mangrove soil collected from...
