“…The observed oxidation of 1,4-dimethoxybenzene to 1,4-benzoquinone also supports a cation radical mechanism. The K m and V max values for veratryl alcohol oxidation (Table III) are comparable to the results reported for LiP isozymes from other white rot fungi (39,40). However, unlike classic LiP isozymes (41,42), Mn(II) concentrations greater than 0.1 mM were found to severely inhibit the oxidation of veratryl alcohol by the Bjerkandera MnP.…”

“…Peroxidase enzyme participates in the construction, rigidification and eventual lignification of cell walls, which protects plant tissues from damage [30,31]. In our study, SA induced CGA and QP dependent POD activities, while MJ induced FA and CA dependent POD activities significantly compared to respective control.…”

Methyl Jasmonate and Salicylic Acid Induced Oxidative Stress and Accumulation of Phenolics in Panax ginseng Bioreactor Root Suspension Cultures

Abstract:To investigate the enzyme variations responsible for the synthesis of phenolics, 40 day-old adventitious roots of Panax ginseng were treated with 200 µM methyl jasmonate (MJ) or salicylic acid (SA) in a 5 L bioreactor suspension culture (working volume 4 L). Both treatments caused an increase in the carbonyl and hydrogen peroxide (H 2 O 2 ) contents, although the levels were lower in SA treated roots. Total phenolic, flavonoid, ascorbic acid, non-protein thiol (NPSH) and cysteine contents and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical reducing activity were increased by MJ and SA. Fresh weight (FW) and dry weight (DW) decreased significantly after 9 days of exposure to SA and MJ. The highest total phenolics (62%), DPPH activity (40%), flavonoids (88%), ascorbic acid (55%), NPSH (33%), and cysteine (62%) contents compared to control were obtained after 9 days in SA treated roots. The activities of glucose 6-phosphate dehydrogenase, phenylalanine ammonia lyase, substrate specific peroxidases (caffeic acid peroxidase, quercetin peroxidase and ferulic acid peroxidase) were higher in MJ treated roots than the SA treated ones. Increased shikimate dehydrogenase, chlorogenic acid peroxidase and β-glucosidase activities and proline content were observed in SA treated roots than in MJ ones. Cinnamyl alcohol Molecules 2007, 12 608 dehydrogenase activity remained unaffected by both MJ and SA. These results strongly indicate that MJ and SA induce the accumulation of phenolic compounds in ginseng root by altering the phenolic synthesis enzymes.

“…transformation of organic molecules to mineral forms, including carbon dioxide or methane, plus inorganic forms of other elements that might have contained the original structures [2,7]. Ferrell et al [44] compared the colour removal efficiency of lyophilized fungal culture with lignin peroxidase, both the lyophilized culture and enzyme decoloured the dye. A well-defined lignin-degrading enzyme system, consisting of lignin peroxidase, Mn (II)-dependent peroxidase (MnP) and glyoxal-oxidase, was found to be involved in the dye degradation.…”

Present review highlights the role of fungi in biodegradation/decolourization of textile dyes and effluents. Though, fungi and bacteria both are the principal decomposer of xenobiotics in the environment but fungi are superior to bacteria in dyes degradation/decolourization due to their superiority in the production of dyes degrading enzymes and as absorbent. The present study focused on the achievements and advancement on the fungal degradation/decolourization of textiles dyes and effluents by the application of potent fungal strains. The biodegradation through fungi or myco-remediation of textile dyes and effluents using potential fungi is comparatively cheap and environmentally safe process, to decompose or mineralize the hardly or less degrading compounds of synthetic dyes. Fungi play an important role to degrade/decolourize the synthetic dyes through enzymes as well as by the absorption, adsorption and accumulation of colourants from the effluents.
