Lignin is a heterogeneous phenolic polymer that gives rigidity to plant cell walls and accounts for 15-40% of the dry weight of biomass [1]. Natural lignocellulosic materials have low solubility and processability, which limits their effective practical application [2]. Modern research on lignin processing focuses on depolymerization processes followed by conversion of the resulting monomers either by hydroprocessing or oxidation. Oxidative conversion of lignin is carried out using biotechnological methods (enzyme...

Multi-enzymatic cascade reactions, that is, the integration of several biocatalytic transformations occurring simultaneously, offer a wide range of possibilities and new ways to synthesize products with high added value. Such systems improve biocatalytic processes by saving time and reducing waste, while being self-sufficient in terms of requirements for related factors. As a more environmentally friendly and sustainable alternative method for the production of chemicals and biological products increases in import...

In recent decades, the interest of researchers has focused on the development of methods for obtaining alternative energy sources. Fischer-Tropsch synthesis is one of the methods for obtaining a wide range of hydrocarbons and their derivatives. Ru, Ni, Fe and Co are the widely used catalytically active metals in FTS. To increase the activity of the catalyst, as well as increase the yield of target products, promoters are introduced into catalytic systems. In FTS, oxides of alkaline and rare earth metals, oxides of...

In the current work, the process of fermentative conversion of animal waste and non-hydrolized plant materials (peat) using food waste and ascorbic acid salts as a stimulants is described. The amino acid composition of the biofermentation products was estimated. The possibility of the target biosynthesis for the production of fertilizers and feed additives with the pre-determined properties was recognized. It was shown that the additive of bread making waste with the concentration of 10 wt. % increases the amino a...
