“…It is therefore unlikely that the PAH derivatives were consumed as nutrients. Luther and Soeder [19], Luther and Shaaban [20] and Luther [21] were able to confirm that the alga, Scenedesmus obliquus , was able to utilize naphthalene sulfonic acids as a source of sulfur for the production of biomass, releasing the desulfonated carbon ring into the medium. However, desulfonation is dependent on the number (1‐NS>1,5‐NDS>1,3,6‐NTS) and position (1,6‐NDS>2,6‐NDS>2,7‐NDS>1,5‐NDS) of the substituents on the carbon structure [21].…”

The microbial degradation of aromatic pollutants has been well characterized over a period of more than 30 years. The microbes of most interest have been bacteria and fungi. Only relatively recently has the question of how algae figure in the catabolism of these compounds attracted a degree of interest. The aim of this review is to highlight the biodegradative capabilities of microalgae on aromatic compounds, ranging from simple monocyclic to more complex polycyclic pollutants. This paper will briefly encompass studies which have investigated the growth on and the oxidation of these compounds by algae, as well as a more detailed characterization of the catabolic sequences involved in the transformation of these compounds.

“…Some green algae (e.g. Chlamydomonas reinhardtii) use NSA as a sulfur source (even in the presence of sulfate) but leave the naphthalene ring undegraded (Luther & Soeder 1987). Most xenobiotic organosulfonates which were examined as carbon or sulfur sources for the growth of aerobic bacteria, are subject to desulfonation (Ruff et al 1999).…”

Biodegradation of naphthalene-2-sulfonic acid present in tannery wastewater by bacterial isolates Arthrobacter sp. 2AC and Comamonas sp. 4BC

Two bacterial strains, 2AC and 4BC, both capable of utilizing naphthalene-2-sulfonic acid (2-NSA) as a sole source of carbon, were isolated from activated sludges previously exposed to tannery wastewater. Enrichments were carried out in mineral salt medium (MSM) with 2-NSA as the sole carbon source. 16S rDNA sequencing analysis indicated that 2AC is an Arthrobacter sp. and 4BC is a Comamonas sp. Within 33 h, both isolates degraded 100% of 2-NSA in MSM and also 2-NSA in non-sterile tannery wastewater. The yield coefficient was 0.33 g biomass dry weight per gram of 2-NSA. A conceptual model, which describes the aerobic transformation of organic matter, was used for interpreting the biodegradation kinetics of 2-NSA. The half-lives for 2-NSA, at initial concentrations of 100 and 500 mg/l in MSM, ranged from 20 h (2AC) to 26 h (4BC) with lag-phases of 8 h (2AC) and 12 h (4BC). The carbon balance indicates that 75-90% of the initial TOC (total organic carbon) was mineralized, 5-20% remained as DOC (dissolved organic carbon) and 3-10% was biomass carbon. The principal metabolite of 2-NSA biodegradation (in both MSM and tannery wastewater) produced by Comamonas sp. 4BC had a MW of 174 and accounted for the residual DOC (7.0-19.0% of the initial TOC and 66% of the remaining TOC). Three to ten percent of the initial TOC (33% of the remaining TOC) was associated with biomass. The metabolite was not detected when Arthrobacter sp. 2AC was used, and a lower residual DOC and biomass carbon were recorded. This suggests that the two strains may use different catabolic pathways for 2-NSA degradation. The rapid biodegradation of 2-NSA (100 mg/l) added to non-sterile tannery wastewater (total 2-NSA, 105 mg/l) when inoculated with either Arthrobacter 2AC or Comamonas 4BC showed that both strains were able to compete with the indigenous microorganisms and degrade 2-NSA even in the presence of alternate carbon sources (DOC in tannery wastewater = 91 mg/l). The results provide information useful for the rational design of bioreactors for tannery wastewater treatment.

“…Wider ranges of compounds can be desulfonated by bacteria (Ztirrer et al 1987) and possibly by algae (Luther & Soeder 1987). Two groups of degradative pathways can be distinguished: firsly, those with desulfonation as the first (or sole) catabolic reaction (Brilon et al 1981a;Luther & Soeder 1987;N6rtemann et al 1986;Swisher 1987;Zfirrer et al 1987;cf. Wittich et al 1988), and secondly, those with reactions prior to desulfonation (Feigel & Knackmuss 1988;Locher et al 1989b;cf.…”

Alcaligenes sp. strain O-1 grew with benzene sulfonate (BS) as sole carbon source for growth with either NH4 ÷ or NH4 + plus orthanilate (2-aminobenzene sulfonate, OS) as the source(s) of nitrogen. The intracellular desulfonative enzyme did not degrade 3-or 4-aminobenzene sulfonates in the medium, although the enzyme in cell extracts degraded these compounds. We deduce the presence of a selective permeability barrier to sulfonates and conclude that the first step in sulfonate metabolism is transport into the cell. Cell-free desulfonation of BS in standard reaction mixtures required 2 mol of 02 per mol. One mol of 02 was required for a catechol 2,3-dioxygenase. When meta ring cleavage was inhibited with 3-chlorocatechol in desalted extracts, about 1 mol each of 02 and of NAD(P)H per mol of BS were required for the reaction, and SO32-and catechol were recovered in high yield. Catechol was shown to be formed by dioxygenation in an experiment involving 180 2. 4-Toluene sulfonate was subject to NAD(P)H-dependent dioxygenation to yield SO32-and 4-methylcatechol, which was subject to meta cleavage. OS also required 2 mol of O2 per mol and NAD(P)H for degradation, and SO32-and NH4 + were recovered quantitatively. Inhibition of ring cleavage with 3-chlorocatechol reduced the oxygen requirement to 1 mol per mol of OS SO32-(1 mol) and an unidentified organic intermediate, but no NH4 +, were observed.
