Bacillus pumilus and Paenibacillus sp. were applied on the paper mill effluent to investigate the colour remotion. Inocula were individually applied in effluent at pH 7.0, 9.0 and 11.0. The real colour and COD remotion after 48h at pH 9.0 were, respectively, 41.87% and 22.08% for B. pumilus treatment and 42.30% and 22.89% for Paenibacillus sp. Gel permeation chromatography was used to verify the molar masses of compounds in the non-treated and treated effluent, showing a decrease in the compounds responsible for the paper mill effluent colour.
短小芽孢杆菌和类芽孢杆菌被应用于造纸厂废水，以研究其脱色效果。接种物分别在 pH 值为 7.0、9.0 和 11.0 的废水中进行应用。在 pH 值为 9.0 时，经过 48 小时后，短小芽孢杆菌处理的实际色度和 COD 去除率分别为 41.87%和 22.08%，而类芽孢杆菌处理的实际色度和 COD 去除率分别为 42.30%和 22.89%。凝胶渗透色谱用于验证未处理和处理过的废水中化合物的摩尔质量，结果表明，废水中引起颜色的化合物的摩尔质量有所降低。
