Abstract
To examine the possibility of protein recycling of shaving scraps containing chromium generated from manufacturing process of leather, the optimum hydrolysis conditions and the withdrawal methods of low molecular weight protein for using the liquid fertilizer sources by investigation of solubilities of hydrolyzed protein, inorganic nutrients contents and molecular weight distributions of hydrolyzed protein from shaving scraps treated with mixed alkaline inducing agents and mixed alkaline proteolytic enzymes including MgO were investigated. In hydrolysis of shaving scraps treated with mixed alkaline inducing agents, the solubility of shaving scraps were clearly different with 65~85% according to the sorts of the inducing agents, and the degree of hydrolysis was high in the order of NaOH,
피혁제조시 발생되는 크롬을 함유한 피혁 고형폐기물인 shaving scrap의 단백질 자원화 가능성을 검토하기 위하여 MgO를 기본으로 하여 alkaline inducing agents 및 alkaline proteolytic enzymes을 혼용처리하여 shaving scrap으로 부터 회수한 가수분해 단백질의 용해도, 무기성분 함량, 분자량분포 등을 비교 검토함으로서 최적 가수분해 조건 및 액체비료의 원료로 활용하기 위한 저분자 단백질의 회수방안을 조사한 결과는 다음과 같다. Alkaline inducing agents의 혼용처리에 의한 shaving scrap의 가수분해 실험결과 7% MgO를 기본으로 하여 alkaline inducing agents 종류에 따라 65~85% 범위로 용해도 차이가 뚜렷하였으며, 가수분해되는 정도는 NaOH>
