硫限制分批富集培养含有一个9多取代萘磺酸盐和接种物从污水产生了几个类群的细菌，可以定量利用19磺化芳香族化合物作为唯一的硫源生长。生长产量为每摩尔硫约4kg蛋白质。比降解率约为4至14 mu kat/kg蛋白质。假单胞菌属，节杆菌属，和一种未鉴定的细菌。每一种都至少磺化了16种芳香族化合物，其中没有一种作为碳源。假单胞菌属菌株S-313将1-萘磺酸、2-萘磺酸、5-氨基-1-萘磺酸、苯磺酸和3-氨基苯磺酸分别转化为1-萘酚、2-萘酚、5-氨基-1-萘酚、苯酚和3-氨基苯酚。用18 O2进行的实验表明，羟基来自分子氧。
Sulfur-limited batch enrichment cultures containing one of nine multisubstituted naphthalenesulfonates and an inoculum from sewage yielded several taxa of bacteria which could quantitatively utilize 19 sulfonated aromatic compounds as the sole sulfur source for growth. Growth yields were about 4 kg of protein per mol of sulfur. Specific degradation rates were about 4 to 14 mu kat/kg of protein. A Pseudomonas sp., an Arthrobacter sp., and an unidentified bacterium were examined. Each desulfonated at least 16 aromatic compounds, none of which served as a carbon source. Pseudomonas sp. strain S-313 converted 1-naphthalenesulfonic acid, 2-naphthalenesulfonic acid, 5-amino-1-naphthalenesulfonic acid, benzenesulfonic acid, and 3-aminobenzenesulfonic acid to 1-naphthol, 2-naphthol, 5-amino-1-naphthol, phenol, and 3-aminophenol, respectively. Experiments with 18O2 showed that the hydroxyl group was derived from molecular oxygen.
