PROCESS OF PREPARING A BIOMASS

摘要

A biomass which is made of a mixed culture of microorganisms is produced by bio-degradation of waste liquor from bisulfite pulping. Under non-aseptic conditions, and using nutrients with the liquor, the latter is treated with acclimatized microorganisms which are derived from sewage. The biomass which is obtained as a result of the multiplication of the microorganisms on the liquor can be separated, dried and pulverized to give a substance which can be used as feed for animals.
