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

In this work, we electrochemically deposited self-doped polyanilines (SPANI) on the surface of carbon-nanoparticle (CNP) film, enhancing the superficial faradic reactions in supercapacitors and thus improving their performance. SPANI was electrodeposited on the CNP-film employing electropolymerization of aniline (AN) and

Orthanilic acid (2-aminobenzenesulfonic acid, (S)Ant), an aromatic β-amino acid, has been shown to be highly useful in inducing a folded conformation in peptides. When incorporated into peptide sequences (Xaa-(S)Ant-Yaa), this rigid aromatic β-amino acid strongly imparts a reverse-turn conformation to

2-Aminobenzenesulphonic acid (2AS) is degraded by Alcaligenes sp. strain O-1 via a previously detected but unidentified intermediate. A mutant of strain O-1 was found to excrete this intermediate, which was isolated and identified by m.s., 1H- and 13C-n.m.r. as 3-sulphocatechol

Growth of Alcaligenes sp. strain O-1 with 2-aminobenzenesulfonate (ABS; orthanilate) as sole source of carbon and energy requires expression of the soluble, multicomponent 2-aminobenzenesulfonate 2,3-dioxygenase system (deaminating) (ABSDOS) which is plasmid-encoded. ABSDOS was separated by anion-exchange chromatography to yield a
