Xinhua News Agency, Nanjing, August 24 (Reporter Wang Wei) reporter 24 from China
Nanjing Institute of Geography and Lakes was informed that the research team recently completed a genome-wide sequencing of a super microalgae genus. This algae is widely distributed in the middle and lower reaches of the Yangtze River in the nest lake, Poyang Lake and other freshwater lakes, not only bear the "heavy responsibility" of producing oxygen and nutrients, but also produce rich oil. Unlocking its "genetic code" will help human beings to study its ecological function in depth and give full play to its energy value.
Xiaoli, a
researcher at the Nanjing Institute of Geography and Lakes who led the study, said michael is a microalgae with a particle size of less than 3 microns and lives in fresh water. They play an important role in lake ecosystems and contribute up to about 60% of the oxygen content of water.
this time, the team successfully obtained the Michael genus algae strain and sequenced the whole genome based on flow cell sequencing techniques. The researchers obtained a total of 5.8Gb of effective sequences and 6649 protein-coded genes. Further genetic analysis shows that Michael can not only use a variety of molecular forms of nutrient salts, a variety of wavelengths of light for photocodying, but also has a unique low temperature adaptation mechanism. This makes it highly viable and capable of surviving in large numbers in lakes that are highly nutritious, turbidity and cool.
"It's worth noting that michael is a 'oil-producing man' in water: about 86 milligrams of oil per litre of mcco-genus. This time, we also found the reason for its strong oil production at the genetic level. There are many kinds and quantities of genes associated with oil anabolism in the genome of this algae. Given its efficient photolycing rate and strong growth, the Genus Michael is likely to be a potential species for future energy production. She said.
research results have been published in the biomedical field of the authoritative journal Biomedical Center Genomics. (Complete)
