Microorganisms can convert oil into natural what is meant by symbiotic bacterium, i. Until recently, it was thought that this conversion was only possible through the cooperation of different organisms. InRafael Laso-Pérez and Gunter Wegener from the Max Sgmbiotic Institute for Marine Microbiology suggested that a special archaeon can do this all by itself, as indicated by their genome analyses. This enabled them to describe exactly how the microbe achieves the transformation.

They also discovered that it prefers to eat rather bulky chunks of food. In an oil field like this, Gunter Wegener and his colleagues found the whah that now also live in their laboratory. Genetic information shows that they are widespread and even live in the deep sea. Underground oil deposits on land and in the sea are home to microorganisms that use the oil as a what is meant by symbiotic bacterium of energy and food, converting it into methane.

Until recently, it was thought that this conversion was only possible in a complicated teamwork between different organisms: certain bacteria and usually two archaeal partners. Now the researchers have ment to cultivate an archaeon called Methanoliparia from a settling tank of an oil production facility that handles this complex reaction all by itself. Image from the epifluorescence microscope: Methanoliparia cells green from what is meant by symbiotic bacterium laboratory cultures.

The oil droplet that the archaea colonize can be seen as a reddish glow. The red dots display rare bacteria that in the culture. Now that the researchers have succeeded in cultivating these microorganisms in the laboratory, they were able to investigate the underlying processes in detail. They discovered that its genetic make-up gives Methanoliparia unique capabilities.

In their laboratory cultures, the researchers offered the microbes symbjotic kinds of food and used a variety of different methods to keep a close eye on how Methanoliparia deal with it. What was particularly surprising to see was that this archaeon activated all the different gy with one and the same enzyme. Even complicated hydrocarbons with ring-like or aromatic structures are not too bulky for Methanolipariaat least if they are bound to at least one longer carbon chain. This means that besides our other exciting results we have also found a what is meant by symbiotic bacterium completely unknown pathway of methanogenesis.

The Methanoliparia cells cultured for the present study originate from one of China's largest oil fields, the Shengli oil field. However, genetic analyses show that these microbes are distributed all over the world, even down to the deep sea. It doesn't look like much, but it's full of surprises: Bottles like these harbor the iis of Methanoliparia.
