Richland, wash. – Those who have disrupted the circadian rhythm, they suffer all kinds of negative effects, including obesity, sleep difficulties and high rates of accidents.
But in cyanobacteria-bacteria is also known as blue-green algae-smooth rhythm can pay for researchers who can prepare more efficiently in a new way to produce biology-based products.
Scientist in the Department of Energy Pacific northwest national laboratory It is displayed how the organism rhythm of the organism can be used to promote production. Payed with unexpected additional production of any substance of interest except nightlight – in this case, sugar.
The work completed by Pavlo Bohutski -led team is part of PNNL Focus on future eventsScientists are discovering the symptoms of an organism, or ways to affect phenotypes, which they can predict and control. Its purpose is to fill a difference in our understanding of the molecular world: while DNA provides a blueprint for the development of an organism, how is that genetic plan applied? How do environmental factor actually determine the symptoms of a person, cyanobacteria and other living things?
In the latest work, published in Microbial cell factoryBohutski’s team studied how the circadians of cyanobacteria control carbon and energy metabolism. He manipulated the atmosphere of cyanobacteria and then monitored the effects.
Generally, the organism absorbs in sunlight during the day, executes photosynthesis and forms energy reserves in the form of glycogen. At night, in the dark, light-acce-performing machinery rests, and organisms direct their energy to restore cellular processes, exclude cell division and maintain its health.
The team changed the input in this natural rhythm, instead maintained the light all night besides normal daylight. Unexpectedly, the cyanobacteria went to a production biping, which produced three times more sucrose a day. Instead of resting, they used additional light to break their energy reserves to make sugar. He reduced the energy spent on maintaining himself and increased energy to create a product.
In other words, the organism transformed its activities into a direct response to an environmental change, away from its typical night activities and redirected to an unusual night activity. A good example of this is How environment affects phenomeOr symptoms, of an organism.
Pnounces, carbon storage, cell division and other important processes switching to changes in the activity of more than 300 genes involved.
Bohutsky said, “Sianobacteria essentially resumed itself, in response to a change in its environment.” “Metabolism and organism phenotypes have changed in a very dramatic way.”
The findings laid a new way to promote the efficiency of cyanobacteria, which are used to produce fuel, foods and industrial chemicals. More broadly, research indicates how environmental changes can determine the molecular miles of organisms of the organisms of what they become and what they do.
More than 100 researchers will discuss related research during first Predictive unprecedented conferenceConducted by PNNL, to be held on 1 April in Richland on 29 April, wash.
Work was funded by PNNL Predictive event initiativeWith partial support from the office of Doo. Some molecular analysis were performed in the environmental molecular science laboratory, which is an office of science user facility located in the PNNL-Richland campus.
Apart from Bohutsky, the author of the paper, Ashley Gillium, Natalie C. Sadler, Shiaoolu Lee, Marxi Garcia, Zachri Johnson, Mariaja Veliyakovi, Young-Mo Kim, Song Feng, Way-Joon Qin and Margaret S. Are cheated.
