The present research aims to enhance the biosurfactant (BS) production using agricultural by-products as a low-cost substrate with the statistical approach. BS production from Bacillus subtilis SASCBT01 was carried out with four different variables such as pH, incubation time, cassava peel waste (CPW) and palmira sprout (PS). The model expected the highest emulsification activity of 65 ± 1·2% after 96-h incubation with 3·0 g l of CPW and PS at pH 7·0. The SASCBT01 strain-based BS was successful at retrieving up to 18% and the highest Pb removal rates were found at 65%. These BS have considered high quality in bioremediation applications.
本研究旨在利用农业副产品作为低成本基质，通过统计学方法提高生物表面活性剂（BS）的产量。采用枯草芽孢杆菌 SASCBT01 进行 BS 生产，考察了 4 个不同变量，即 pH 值、培养时间、木薯皮废物（CPW）和棕榈芽（PS）。该模型预计在 96 小时的培养时间内，在 pH 值为 7.0 时，使用 3.0 g/L 的 CPW 和 PS，乳化活性最高可达 65%±1.2%。基于 SASCBT01 菌株的 BS 成功回收了高达 18%的 Pb，并且发现最高的 Pb 去除率为 65%。这些 BS 被认为在生物修复应用中具有很高的质量。
