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−1 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.

枯草芽孢杆菌SASCBT01低成本生物表面活性剂的优化及其环境修复潜力

本研究旨在通过统计方法使用农业副产品作为低成本底物来提高生物表面活性剂 (BS) 的生产。枯草芽孢杆菌 SASCBT01 的 BS 生产使用四个不同的变量进行，例如 pH 值、孵育时间、木薯皮废料 (CPW) 和棕榈芽 (PS)。该模型预期在 pH 7·0 条件下与 3·0 gl-1 CPW 和 PS 孵育 96 小时后，最高乳化活性为 65 ± 1·2%。基于 SASCBT01 菌株的 BS 成功回收高达 18%，最高的铅去除率达到 65%。这些 BS 在生物修复应用中被认为是高质量的。
