BIOCATALYTIC TECHNOLOGIES IN CONSTRUCTION AND HOUSING AND COMMUNAL SERVICES: APPLICATION AND PROSPECTS

This paper describes the use of biocatalytic technologies in construction and housing and communal services. Special attention is paid to the use of microbiological processes for the modification of soil bases, concretes and building mortars. The problems and directions of future research in this area are considered.

ISOLATION OF MICROMYCETES, POTENTIAL LIGNIN DESTRUCTORS, FROM WOOD PROCESSING ENTERPRISES WASTE

Fungal isolates were obtained from the dumps of a wood processing enterprise. Their physiology was studied, and partial species identification was carried out in the ITS region.

A NOVEL C1Q DOMAIN-CONTAINING PROTEIN ISOLATED FROM THE MOLLUSK MODIOLUS KURILENSIS RECOGNIZING GLYCANS ENRICHED WITH ACIDIC GALACTANS AND MANNANS IS VERY PROSPECTIVE FOR BIOMEDICAL PURPOSES

A novel C1qDC bivalve protein from the bivalve Modiolus kurilensis (MkC1qDC-1) was identified, isolated and characterized. MkC1qDC-1 demonstrated the inhibition of HeLa cell proliferation and recognition of some cancer cell phenotypes in comparative analysis on several cell lines, suggesting biomedical potential of this protein.

OBTAINING OF CELLULAR PREPARATIONS OF RAT AND HUMAN OLFACTORY MUCOSA AND THEIR INFLUENCE ON THE SIZE OF MODELED SPINAL CORD CYSTALS

Enriched cultures of olfactory ensheathing cells and neural stem/progenitor cells were obtained according to our developed protocols from the olfactory mucosa of rat and human. It has been shown that only transplantation of human and rat olfactory ensheathing cells leads to a significant decrease in the size of cysts, as well as their complete disappearance in some animals.

CHARACTERISTICS OF MIRNA BINDING SITES IN MRNAS OF MYB GENES OF ARABIDOPSIS, SOYA AND GRAPE

The characteristics of various miRNA binding sites in the mRNAs of the MYB transcription factor genes of Arabidopsis thaliana, Glycine max and Vitis vinifera have been established. The most conserved miRNA binding sites were the binding sites of the miR828 family.

BIOSYNTHESIS OF BUTYRIC ACID FROM GLUCOSE THROUGH THE INVERTED FATTY ACID BETA-OXIDATION PATHWAY BY RECOMBINANT ESCHERICHIA COLI STRAIN IN BIOCATALYTIC MODE DUE TO ENFORCED ATP HYDROLYSIS

The feasibility of the application of enforced ATP hydrolysis to ensure anaerobic functioning of Escherichia coli strain producing butyric acid through the inverted fatty acid beta-oxidation pathway as a full-cell biocatalyst has been demonstrated.

ENZYMES AS TARGETS FOR THE EFFECTS OF ORGANOPHOSPHORUS COMPOUNDS AND THEIR BIOCATALYTIC DETOXIFIERS: A NEW LOOK AT A WELL-KNOWN PROBLEM

The conducted studies made it possible to identify new targets in the form of the most important decarboxylases for the possible negative effects of known organophosphorus compounds and to assess their potential danger to humans.

BIOCATALYTIC PROCESSES OF LOW-TEMPERATURE SYNTHESIS OF ESTERS. MODULATION OF THE FUNCTIONAL PROPERTIES OF LIPASE BY THE CHOICE OF SOLVENT AND SUPPORT FOR IMMOBILIZATION

Biocatalytic processes for the synthesis of valuable products, such as different esters for various purposes, have been studied using heterogeneous biocatalysts prepared by immobilizing the recombinant lipase rPichia/lip on mesoporous silica (SiO2) and macroporous carbon aerogel (MCA). It was found that the functional properties of immobilized lipase, such as enzymatic activity, specificity toward pair of substrates (acid and alcohol), the molecules of which differ in the number of carbon atoms (C), as well as operational stability, depended on the method of adsorptive immobilization, the chemical nature of the support, and polarity of the organic solvent, i.e. logP. The functional properties of rPichia/lip have been shown to be modulated by the selection of an organic solvent and support for lipase immobilization.

MAGNETIC SELECTION OF TRANSDUCED CELLS USING NOVEL SURFACE MARKERS

The possibility of using HA- and FLAG–tags embedded into CD52 surface protein for magnetic separation of transduced cells in vitro was investigated. The efficiency of selection of transfected cell lines, both with single and binary tags, was shown to exceed 85%. Thus, surface markers on the basis of CD52 protein with integrated HA- and FLAG-tags are applicable for cell selection by the MACS method.
