Abstract
The effect of humic substances on bioconversion of glucose into ethanol is investigated. It is established that their presence in the reaction mixture with the optimal concentration of 0.001 % accelerates fermentation process. The reaction of glucose fermentation can be recommended for use as a new rapid and economic test for the biological activity of various humic preparations and optimization of their concentrations in aqueous solutions, which can be used, for stimulation of the growth of microorganisms, plants, and animals.
