Biological deodorizing material, method for producing biological deodorizing material, and biological deodorizing method

摘要

PROBLEM TO BE SOLVED: To provide a process for producing a biological deodorant which does not require a fresh installation space, allows simple equipment and standardization, is free from maintenance, is low in an installation cost and is high in a treatment effect and is extremely excellent in stability. SOLUTION: This process for producing the biological deodorant comprises subjecting vegetable-base materials to a fermentation treatment by composite bacterium species consisting mainly of Bacillus thuringiensis and Bacillus pumilus to obtain an intermediate fermentation product and depositing the Bacillus bacteria propagated by the fermentation treatment on the intermediate fermentation product.
