The urgency of the thesis The ocean accounts for 70 of the earth s surface where there is the largest biological diversity on earth. It is home to 34 of the 36 animal and plant sectors on earth with more than 300 000 known species. The marine environment has been known as a rich source of natural compounds such as a huge pharmaceutical warehouse awaiting exploration and discovery. Characteristics of harsh deep sea habitats are the conditions for forming organic compounds with unique chemical structure characteristics and precious biological activity. The study of secondary active ingredients produced from marine microorganisms in the world has achieved many remarkable achievements. Among them are many secondary compounds with interesting chemical structure and biological activity. At the same time many of these compounds are being tested further for medical applications. Vietnam is located in the Pacific region with sovereignty with an area of about 1 000 000 km2 .
