Abstract
During the last decades, marine microorganisms have been turned out to be a vast unexploited reservoir of metabolic diversity. Thus, research on natural products derived from marine microorganisms has increased tremendously in recent years due to the demand for compounds having potential pharmaceutical applications or economical value as cosmetics, drugs, fine chemicals and functional personal-care products (Rashad et al., 2015). Discovery of novel marine natural products of pharmaceutical importance is a challenge because of a number of shortfalls and hindrances associated with the isolation, characterization, sample supply and environmental considerations. The number of antimicrobial agents isolated from marine microbes is limited due to the lack of cultivable varieties of fungi and bacteria from this source and thus the approved drugs are also very less (Bhatnagar and Kim 2012).
