Abstract
Abstract A method for cultivating, under alkaline conditions, microorganisms in a culture medium containing, as a carbon source, the extracted liquor or spent liquor derived from alkaline pulping is presented. In this cultivation, organic acids contained in the extracted liquor or spent liquor can be effectively utilized. Typical microorganisms cultured are bacteria belonging to the genera Bacillus, Arthrobacter, Corynebacterium and Brevibacterium.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
114 words
A method for cultivating a microorganism comprising the steps of: inoculating at least one microorganism which grows well under alkaline conditions and is selected from the group consisting of Bacillus SP. FERM-P No. 5861 and SP. FERM-P No. 5862, Arthrobacter SP. FERM-P No. 5863 and SP. FERM-BP No. 88, Corynebacterium SP. FERM-BP Nos. 89 and 90, and Brevibacterium FERM-BP Nos. 91 and 92, into a culture medium containing, as a carbon source, extracted liquor or spent liquor derived from alkaline pulping; and cultivating the inoculated microorganism in the culture medium at a pH of 8.0 to 12.5 under an aerobic condition; whereby organic acids contained in the extracted liquor or spent liquor are utilized.
