EXTREMOPHILE CULTURE COLLECTION FROM EXTREME AREA OF IRAN

Abstract

The number of studies on extremophilic organisms has grown exponentially in the last few years. These exotic organisms (extremoplilees) are adapted to living at 100 c. In volcanic springs, at low temperatures in the cold polar seas, at high pressure in the deep sea, at very low and high ph values (ph 0-1 or ph 10-11) or at hight salt concentration (35%). Recent developments clearly show that cell components of extremoplilic archaea and bacteria are unique and deliver a valuable source of new biocatalysts and compounds. Since many industrial enzymes are required to function under extreme conditions, there is also a considerable commercial pressure to discover stable biocatalists in modern biotechnology. Extremophiles and their cell components, therefore are expected to play an important role in the chemical, food, pharmaceutical, paper and textile industries as well as environmental biotechnology. The Iranian plateau has a very remote past which even history does not remember the sculptures and images of persepolis say of its glory. The iranian plateau, has been a stage to unique events within the spectrum of world transformations.throughout this immense and long lasting immigration from the north of africa tothe south of asia and durind all these geographical and climatic changes plants, animals and microorganisms become widely extinct. The better adapted and more efficient one appeared to substitute the extinct species, finally leading to the present form of the country. Scientists geobotanically divide the northern hemisphere of the earth into four main regions, Iran his like a connecting stretch at the intersection of these four botanic regions and situation and factors from each of these regions influence the biodiversity of Iran. Research on marine and terestrial extremopliles microorganisms was started in Persian Gulf biotechnology research center to provide high quality lab and pilot plant service for isolation, identification, maintenance and screening of new active metabolites from microorganisms of different extreme area of Iran. The results of this study will be presented in this conference.
