Desulfonation of biotransformation products from commercial linear alkylbenzenesulfonates

Abstract: Earlier work shows that the biodegradation and biotransformation of commercial linear alkylbenzenesulfonate (LAS) as a carbon source for growth leads to a residue of sulfonated aromatic compounds, termed refractory organic carbon, from the synthetic by‐products. We now show that this refractory organic carbon, after separation from sulfate ion, is utilized extensively as a sulfur source for bacterial growth. The products of desulfonation are expected to be biodegradable, so we question the value of adjectives … Show more

“…strain BN6 [130,131]. In contrast, the assimilation of sulfur from these compounds is characterized by the wide substrate ranges of the organisms involved; Pseudomonas putida S-313 desulfonates several hundred compounds [44,45,132], and other bacteria have similar properties [46,129]. Indeed, many apparently unusual compounds are subject to desulfonation [48,132,133] and even to more complex transformations [134] under sulfate-limited conditions; desulfonation of a wide range of azo dyestu¡s and other complex arenesulfonates has also been observed [45,97,135].…”

“…Hasil degradasi selanjutnya dikeluarkan dari sel melalui lisosom yang bergerak menuju dinding plasmolema, yang selanjutnya vesikula akan bersatu dengan plasmolema. Proses selanjutnya metabolit hasil degradasi dikeluarkan dari sel (Davis et al, 1990;Mampel et al, 1998). Komunitas mikroba lumpur aktif yang didominasi oleh bakteri gram negatif, termasuk di dalamnya á sub class Proteobacteria (Schleheck et al, 2000;Denger & Cook.…”

“…Oleh karena diversitas jenis yang tinggi, penggunaan komunitas bakteri untuk biodegradasi detergen memiliki berapa keuntungan dibandingkan dengan kultur tunggal (Tchnolobagus, 1990). Hal tersebut disebabkan oleh kompleksnya stuktur kimia molekul detergen (Mampel et al, 1998), dapat didegradasi oleh kompleksenzim yang dihasilkan oleh komunitas bakteria dalam lumpur aktif. Di samping itu degradasi oleh komunitas bakteria diharapkan akan lebih stabil, karena dilakukan oleh berbagai jenis bakteria.…”
