Study of the recycle of the waste hair and feather

以零排放为目标，研究了废弃动物毛和羽毛的利用。建立了羽毛提取简易系统。将羽毛加水以减小体积，在低浓度碱性溶液中高温提取。这些方法已申请专利PCT/JP2005/005672“水解角蛋白的制造”。对水解角蛋白作为化妆品原料的有效性进行了考察。通过电镜分析，用水解角蛋白对实验损伤的头发进行修复。此外，对皮革的修复和保护效果进行了识别，并将这些数据申请了专利“2005-282444”，“皮革修复和保护试剂”。作为动物毛发和羽毛的分解方法，分泌角化酶的微生物的筛选已与东京农业大学医学微生物研究所、东京农业大学动物生命科学研究所进行了共同研究。)，以及东京都皮革技术中心。在这些研究中，发现了一些有前景的微生物和新的微生物检测方法。

The utilization of waste animal hair and feather has been studied to aim the zero-emission. The easy extraction system of feather was established. Feather was made damp with water to reduce the volume, and extracted in low concentration alkaline solution at high temperature. These procedures were applying as a patent PCT/JP2005/005672 'Manufacture of hydrolyzed-keratin'.It was examined to the effectiveness of hydrolyzed-keratin for the cosmetic material. The damaged hair by experiment has been repaired with hydrolyzed-keratin by electronmicroscopic analysis. Moreover, the effects of the repair and protect of leather were recognized, and those data were applied for patent '2005-282444, 'repair and protect reagents of leather'.As the decomposing methods of animal hair and feather, the screening of the microorganisms to secrete the keratinase has been made a common study with Institute of Medical Micology (Teikyo University), Animal Life Science (Tokyo Univ.of Agri.and Technol.), and Tokyo Metropolitan Leather Technology Center. In those studies, some promising microorganisms and new detection methods of microorganisms were discovered.
