L-amino acid oxidase is widely found in diverse organisms and has different properties. It is thought to contribute to antimicrobial activity, amino acid catabolism, and so forth. The purpose of this communication is to summarize the advances in non-snake venom L-amino acid oxidase, including its enzymatic and structural properties, gene cloning and(More)
L-amino acid oxidase (LAAO) is attracting more attentions due to its broad and important biological functions. Recently, an LAAO-producing marine microorganism (strain B3) was isolated from the intertidal zone of Dinghai sea area, China. Physiological, biochemical, and molecular identifications together with phylogenetic analysis congruously suggested that(More)
To predict the final fate of 2,4,6-trinitrotoluene (TNT) and its intermediates in an anaerobic fermentative solution containing reduced sulfur species and to provide a basis for the adoption of remediation methods, we investigated the pathways of TNT (TNT(0) = 50 mg/L) reduction by Na(2)S at 30 ± 1 °C in an acetic acid-sodium bicarbonate buffer. Liquid(More)
A new phenylethanoid, 1-O-β-d-(4-hydroxyphenyl)-ethyl-6-O-vanilloyl-glucopyranoside (1), and a new furofuran lignan, (7R,7′R,7′′S,8S,8′S,8′′R)-4′, 4′′-dihydroxy-3,3′,3′′,5-tetramethoxy-7,9′:7′9-diepoxy-4,8′′-oxy-8,8′-sesquineolignan-7′′,9′′-diol (2), along with five known compounds (3–7) were isolated from the roots of Ilex pubescens. Their chemical(More)
One marine bacterial strain, R3, has been newly isolated from the intertidal zone of Dinghai sea area. Measurements of a-keto acids and H2O2 existing in fermentation supernatant were carried out to show that R3 can produce L-amino acid oxidase (LAAO) with a broad substrate specificity. Physiological and biochemical analysis showed that it can grow great at(More)
To account for the fast disappearance of TNT in anaerobic fermentative liquid, we investigated TNT (TNT(0)=50 mg/L) reduction by Na(2)S at 30+/-1 degrees C in two types of buffer systems, a phosphate buffer (PB, system A) and a CH(3)COOH-NaHCO(3) buffer (system B). The effects of pH, sulfide concentration and buffer system on the conversion and reaction(More)
Two new compounds, 2″-O-feruloylisoswertiajaponin (1) and (2E)-2-methyl-1-O-vaniloyl-4-β-d-glucopyranoside-2-butene (2), along with one indole alkaloid and five known flavonoids, were isolated from the flowers of Trollius chinensis Bunge. Their structures were elucidated on the basis of spectroscopic evidence (UV, IR, HR-ESI–MS, NMR).
