A method is provided for the production of alcohol from trees, the method comprising a step of treating a subject tree with mother cell lyases formed through cytolysis associated with sporulation of spore-forming aerobic bacteria, thereby degrading said tree into a powdery state and obtaining a tree degradation product; a step of sterilizing said tree degradation product; a step of treating said sterilized tree degradation product with a koji fungus (Aspergillus oryzae) thereby carrying out a primary fermentation; a step of adding a yeast to the fermentation broth obtained by said primary fermentation thereby carrying out a secondary fermentation; and a step of filtering the fermentation broth obtained by said secondary fermentation, wherein said mother cell lyases are obtained by culturing said spore-forming aerobic bacteria, subjecting the resultant culture medium to a starvation state, thereby converting said bacteria into endospores, and removing impurities including said endosporic bacteria from said culture medium and wherein said spore-forming aerobic bacteria are MRE symbiotic bacteria.
