    摘要: A method of producing inosine and/or guanosine comprising cultivating a microorganism in a medium containing a carbohydrate, in which method a carbohydrate is added either continuously or intermittently to the medium when and in the state that the concentration of the carbohydrate in the medium is less than about 1 percent so that the carbohydrate concentration of the medium is maintained below about 1 percent.

    摘要: A method of producing guanosine using an adenine-requiring microorganism, in which method the amount of the adenine-containing material to be added to the initial medium is restricted to not more than 50% of the required amount and, after the adenine-containing material added to the initial medium has been consumed almost completely, the remainder of the required amount is added intermittently or continuously.

    摘要: In a fermentation procedure for the production of nucleosides i.e. inosine and/or guanosine using an adenine-requiring microorganism, the fermentation is carried out by allowing a source of adenine to be present in the medium in an excess amount over the amount of adenine that would be conductive to a maximum yield of inosine and/or guanosine in aerobic culture using ordinary air, and cultivating the microorganism while an oxygen-rich gas is bubbled into the medium. Thus, inosine and/or guanosine are accumulated in high yield in the fermentation broth.
