FIELD: chemistry.
SUBSTANCE: glue contains boric acid and cultural liquid. Cultural liquid is obtained by addition into nutrient medium of medium, which contains microorganism Leuconostoc mesenteroides. Nutrient medium is formed by dilution of molasses or treacle with buttermilk and grains. Molasses or treacle is wastes of sugar production, buttermilk is waste of diary industry, and grains are waste of alcohol-producing industry. Further cultivation is realised at temperature 24-26°C during 24-48 hours.
EFFECT: glue composition has increased adhesive properties and low cost price.
