General information
The laboratory was founded by the project “Biotechnology of New Materials” in SibFU, Institute of Fundamental Biology and Biotechnology, which had won the competition for the mega-grants of Russian Federation Government within the framework of the program to support research in Russian higher education institutions, supervised by the world leading scientists.
The project is focused on the establishment of the Center of biotechnology excellence; it includes fundamental research, educational and innovative activities in the field of biotechnology of new biomaterials.
The project is fulfilled by the Basic department of Biotechnology, involving the department for Medical Biology and others from SibFU, and resulted with the creation of the Lab of New Materials.

Using the developed modes of fermentation and the bacteria strains (Alcaligenes eutrophus В-5786, Ralstonia eutropha В-8562, Cupriavidus eutrophus ВКПМ В-10646) the family of degradable biopolymers (polyhydroxyalkanoates, PHAs) was synthesized. With implementation of gas-liquid chromatography combined with mass-spectrometry the composition of the samples was determined: poly-3-hydroxybutyrate; copolymers of 3-hydroxybutyrate and 3-hydroxyvalerate; copolymers of 3-hydroxybutyrate and 3-hydroxyhexanoate; copolymers of 3-hydroxybutyrate and 4-hydroxybutyrate; three-components samples containing monomers of 3-hydroxybutyrate, 3-hydroxyvalerate and 3-hydroxyhexanoate.
Experimental polymer samples were synthesized and purified to a homogenous condition. Using X-Ray, DTA and HELC methods physical and chemical properties of the polymer samples were studied. Copolymers containing monomers of 3-hydroxyvalerate and 3-hydroxyhexanoate were characterized by the minor degree of crystallinity (50-6%) in comparison with the highly crystalline homopolymer of 3-hydroxybutyrate (76-80%). Inclusions of 4-hydroxybutyrate (if compared to 3-hydroxyvalerate and 3-hydroxyhexanoate) influence significantly the ratio of crystalline and amorphous zones in the copolymers, thus significantly decreasing the crystallinity of the latter (down to 12-40%) depending on the value of the fraction of 4-hysdroxybutyrate. The molecular weight and molecular-weight distribution of the synthesized polymer samples varied between 540 000 ± 9 600 and 1 300 000 ± 28 700 Da at polydispersity from 1.60 ± 0.03 to 2.76 ± 0.03 without clear dependence on the copolymer’s composition.
