Estimating the term…
The process according to the invention comprises submerged cultivation of microorganisms producing an amino acid in a nutrient media including nitrogen, mineral salts and a source of carbon - a mixture of hexose and pentose monosaccharides obtained by percolation hydrolysis of cellulose-containing plant raw materials, purified to remove furfural and containing oxymethyl furfural and lignogummin substances in an amount of 1-3% by weight of the monosaccharides. The advantage of the process according to the invention resides in the abundance and low cost of the carbon source, reduction of the number of production steps, the presence of a mixture of monosaccharides stimulating the growth of microorganisms in the solution and improvement of quality of the end product.
A process for producing an amino acid, by means of submerged cultivation of an amino acid producing microorganism in a nutrient medium comprising nitrogen, mineral salts, and a mixture of hexose and pentose monosaccharides obtained by percolation hydrolysis of cellulose-containing plant raw materials, purified to remove substantially all furfural and containing oxymethyl furfural and lignogummin substances in an amount of 1-3% by weight of said monosaccharides.
