中文摘要

Poly Lactic Acid (PLA) is the first commodity polymer produced from renewable resources. It provides environmental benefits since it requires lower energy in polymer production and in turn reduces green house gas release. In recent years, Response Surface Methodology (RSM) is extensively used in optimization study due to its effective and time-saving advantages. It is widely used to predict surface responses and study the interactions among variables. Applying RSM, this study focuses on parameters optimization in microorganism fermentation process using Aneurinibacillus migulanus. The 3D response surface plots and 2D contour plots are created by Box-Behnken Design (BBD) and applied to optimize the fermentation process parameters. The results indicate three variables; pH, temperature (°C) and shaking speed (rpm) have significant effects on PLA degradation. The optimum condition is obtained as: pH 8, 40.5 °C and 194 rpm. In addition, the strain degraded PLA film significantly at the maximum level of 69.62% within 20 days in liquid medium. The results from this study can be applied to a highly effective and environmental biodegradable plastics production. However, this study is a pioneer in applying A. migulanus to PLA film degradation and RSM. Therefore, a well-modified technique to better reflect its optimization is needed for future research.
