Ancient fungus 'revived' in lab The fungi (blue streak) were isolated from deep sea sediments Fungus from a deep-sea sediment core that is hundreds of thousands of years old can grow when placed in culture, scientists have discovered. Indian researchers say the fungi come from sediments that are between 180,000 and 430,000 years old. The finding adds to growing evidence for the impressive survival capabilities of many microorganisms. They are the oldest known fungi that will grow on a nutrient medium, the scientists say in Deep Sea Research I. The core was drilled from a depth of 5,904m in the...
