Abstract

The dispersion effect of degraded cellulase from Bacillus methlylotrophicus Y37 and sodium dodecyl sulphate (SDS) together on copper(II) phthalocyanine (CuPc) pigment is studied for the first time in this study. Particle size distribution is used to determine the effect of degradation time for cellulase (1,2,3,4,5,6 and 7 hours). Spectral analysis as UV-Vis, fluorescence, and particle size analysis are investigated to find out the degraded degree of the enzyme. For this work, 4 hours is found to be the optimum degradation time. The collaborative effect of SDS with degraded cellulase as dispersant on CuPc is also examined. The effect of degraded cellulase: SDS dispersion solution on CuPc suspension is determined by UV-Vis, fluorescence, and FT–IR analysis. It is concluded that CuPc has better stability as a pigment when the degraded cellulase and SDS are used together as dispersants in this work.

摘要

甲基营养芽孢杆菌降解纤维素酶的分散作用本研究首次研究了 Y37 和十二烷基硫酸钠 (SDS) 在铜 (II) 酞菁 (CuPc) 颜料上的作用。粒度分布用于确定纤维素酶降解时间（1、2、3、4、5、6 和 7 小时）的影响。研究了光谱分析如 UV-Vis、荧光和粒度分析，以找出酶的降解程度。对于这项工作，发现 4 小时是最佳降解时间。还研究了 SDS 与作为分散剂的降解纤维素酶对 CuPc 的协同作用。降解纤维素酶的影响：SDS 分散溶液对 CuPc 悬浮液的影响通过 UV-Vis、荧光和 FT-IR 分析确定。结论是，当降解的纤维素酶和 SDS 一起用作本工作中的分散剂时，CuPc 作为颜料具有更好的稳定性。
