There is a need for new drugs especially novel antibiotics, anticancer compound, antibiotic against multi drug-resistant bacteria. The discovery and development of new drugs from marine microbes played a significant role over the last few decades. The world oceans comprise a rich diversity of microbial life with current estimates reaching over a million different species. Marine microbes are important from both ecological and biotechnological point of view. Marine microbial bioactive compounds have attracted increasing attention from microbiologists, taxonomists, ecologists, agronomists, chemists and evolutionary biologists.
