Natural production of ethanol exposed to 5,7,8-trimethoxycoumarin

Coumarins are a class of phenolic compounds found in plant, microorganism, and sponges that have many biological properties and therapeutic applications. The efficacy of 5,7,8-trimethoxycoumarin on natural production of ethanol by Saccharomyces cerevisiae NCIM -2086 has been assessed. It has been found that the coumarin, i.e., 5,7,8-trimethoxycoumarin under trial has stimulatory effect on natrual production of ethanol by Saccharomyces cerevisiae NCIM -2086 and enhances the yield of ethanol to an extent of 18.823% higher in comparison to control fermentor flasks, i.e., 4.25 ml/100mL in 47 hrs of incubation period, 4.9 pH and 310C temperature with 16% (w/v) molasses solution.
