In microbial treatments of agricultural industrial wastes containing lignins such as pulp waste, the clarification and the efficiency of COD removal of wastes may be elecated, if the adsorption on lignins on microorganisms is utilized for the elimination of lignins in waste.In view of this, moulds (identified as Aspergillus sp. and Penicillium sp.) which adsorb lignins efficiently, were separated from the mycelial maps formed over kraft waste, and experiments on the clarification of lignin-contianing media were carried out by using these moulds.As a result, it has been found that the degree of clarification is remarkably elevated and lignins in the media were almost thoroughly eliminated by these moulds during shaking culture for a week under growing conditions of 30℃ and pH 6 to 8,provided sugars as a carbon source are added in a small amount (less than 0.05%) to the media containing 0.1% lignin.In addition, a further investigation showed that Aspergillus strains in stock cultures also adsorbed lignins and clarified the lignin-containing media but that other moulds such as rot fungus adsorbed no lignins.
