Decolorization of oxygen-delignified bleaching effluent (abbreviated as OBE) and biobleaching of oxygen-delignified kraft pulp (OKP) were conducted using a non-white rot fungus Geotrichum candidum Dec 1 (abbreviated as Dec 1) which has ability to decolorize various synthetic dyes and molasses. Dec 1 decolorized up to 77% of OBE for 6 days. In addition, Dec 1 increased the brightness of OKP from 47.8% to 51.2% and decreased the kappa value of OKP from 12.4 to 10.4 points during a 6-day incubation period at a 25% of pulp-concentration. At 2% pulp-concentration, the brightness of OKP increased by 13% and the kappa value of OKP decreased by 4 points only for a 3-day incubation period. When the decolorized OBE was used for bleaching of OKP, the brightness of OKP increased to 62.7% under the shaking culture to a 2% pulp-concentration using culture fluid of decolorized OBE. It was revealed that Dec 1 is a potential to apply for decolorization of wastewater and biobleaching of pulp in paper-mills.
使用具有使各种合成染料和糖蜜脱色能力的非白腐真菌白地霉Dec 1（简称为Dec 1）对氧脱木素漂白废水（简称为OBE）进行脱色，并对氧脱木素硫酸盐浆（OKP）进行生物漂白。Dec 1在6天内使OBE的脱色率高达77%。此外，在纸浆浓度为25%的条件下，经过6天的培养期，Dec 1使OKP的亮度从47.8%提高到51.2%，并使OKP的卡伯值从12.4降低到10.4。在纸浆浓度为2%时，仅经过3天的培养期，OKP的亮度提高了13%，卡伯值降低了4个点。当使用脱色后的OBE对OKP进行漂白时，在纸浆浓度为2%的条件下，使用脱色后的OBE培养液进行振荡培养，OKP的亮度提高到了62.7%。结果表明，Dec 1具有应用于造纸厂废水脱色和纸浆生物漂白的潜力。
