FERMENTATION PRODUCT AND PROCESS FOR PRODUCING THE SAME

摘要

A fermentation product having excellent water retentiveness and permeability and containing a slow-release fertilizer component is obtained by growing microorganisms which are viable in an alkaline environment sequentially and preferentially in accordance with the environment which varies with the lapse of time to thereby effect alkaline fermentation of the reaction product. The fermentation product is a product of reaction btween a putrefacient waste comprising a solidliquid mixture and additives mainly comprising highly active calcium oxide and contains microorganisms viable in a highly alkaline environment with a pH value of 12 or above. The microorganisms are composed of a bacterial group comprising first group bacteria which begins growing in a pH range from 11 to less than 12, second group bacteria which grows well in a pH range from about 11 to 9 and third group bacteria which grows well below a pH of about 9, fungi and bacterium 90A1. The pH of the fermentation product is maintained near 8 as a result of the bacteria growth.
