The degradation of of lineal alkylbenzene sulphonate (LAS) was studied in a two-stage anaerobic system where the acidogenic reactor was bioaugmented with a strain of Pseudomonas aeruginosa (M113). This is a strain, which under aerobic and denitrifying conditions uses LAS as carbon source. Results show that LAS was only degraded within the acidogenic stage while in the methanogenic reactor there was no degradation and eventually there was an inhibition due to a LAS accumulation in the sludge. During the experiment, the M113 strain remained in the acidogenic conglomerate (at around 10(4) CFU/mL) although there is no evidence of their involvement in LAS degradation.
在一个两级厌氧系统中研究了直链烷基苯磺酸盐（LAS）的降解情况，其中产酸反应器用一株铜绿假单胞菌（M113）进行了生物强化。这是一种在好氧和反硝化条件下以LAS为碳源的菌株。结果表明，LAS仅在产酸阶段被降解，而在产甲烷反应器中没有降解，最终由于污泥中LAS的积累而产生了抑制作用。在实验过程中，M113菌株留在了产酸聚集体中（约为10⁴CFU/mL），尽管没有证据表明它们参与了LAS的降解。
