Scientists from Russia turned selhozgodu in a unique nanocellulose.
Scientists from Biysk came up with a cheap method of production of nanocellulose, unique material to create filters and artificial limbs, using bacteria and conventional agricultural waste. The recipe is "cooking" this material was presented to the forum BioTechWorld, held recently in Moscow.

"The main objective of our project is to develop the engineering aspects of the technology of Buryat scientific center of non-food raw materials. Knowing these aspects will help create the technology of its receipt with desired properties for specific applications," said Catherine kashcheeva Institute of problems of chemico-energy technologies SB RAS, whose words the press service of the RSF.

 

In addition to conventional cellulose which may be derived from any arbitrary piece of wood or plants, there is the so-called nanocellulose is a special material that consists of a very thin, long, and structured fibers of this biopolymer. In principle, it can be obtained by steeping wood pulp in acid, however today, such a material is manufactured by using special microbes of the genus Gluconobacter.

 
 

Growing colonies of such bacteria and occasionally freezing them, scientists can obtain the sheets very clean and unique properties of cellulose, the production of which would be too expensive in the application of vegetable raw materials. On the other hand, cultivation of microbes is also pretty expensive, since they feed primarily on glucose and reproduce only in a particular nutrient medium.

 

 

Kashcheeva and her colleagues were able to reduce the cost of production of "food" for these microbes, learning to decompose the husk wasp and grass biomass, agricultural waste, sugar and other edible molecules using small amounts of nitric acid, alkalis and enzymes.

As scientists hope that soon they will have to develop a whole technological chain for the production of cheap nanocellulose. It will accelerate its penetration into medicine, science, and everyday life of Russians. These studies were interested in the Russian scientific Fund, took the decision to support the development of Biysk scientists.

Today, as noted by kashcheeva and her colleagues, nanocellulose used to create superfine filters clean water, prosthetic hands and feet, absorbent dressings for wounds and many other useful products.
