Bioconversion of ferulic acid obtained from wheat bran into vanillin
In this work the possibility of producing vanillin through microbial bioconversion from ferulic acid obtained from the enzymatic hydrolysis of wheat bran has been explored. The biocatalyst employed was Escherichia coli JM109/pBB1, a recombinant strain containing the genes from Pseudomonas fluorescens BF13 for the transformation of ferulic acid into vanillin. The substrate of the bioconversion, ...
متن کاملFungal Bioconversion of Lignocellulosic Residues; Opportunities & Perspectives
The development of alternative energy technology is critically important because of the rising prices of crude oil, security issues regarding the oil supply, and environmental issues such as global warming and air pollution. Bioconversion of biomass has significant advantages over other alternative energy strategies because biomass is the most abundant and also the most renewable biomaterial on...
متن کاملMolecular characterization of genes of Pseudomonas sp. strain HR199 involved in bioconversion of vanillin to protocatechuate.
The gene loci vdh, vanA, and vanB, which are involved in the bioconversion of vanillin to protocatechuate by Pseudomonas sp. strain HR199 (DSM 7063), were identified as the structural genes of a novel vanillin dehydrogenase (vdh) and the two subunits of a vanillate demethylase (vanA and vanB), respectively. These genes were localized on an EcoRI fragment (E230), which was cloned from a Pseudomo...
متن کاملMetabolic pathway reconstruction of eugenol to vanillin bioconversion in Aspergillus niger
Identification of missing genes or proteins participating in the metabolic pathways as enzymes are of great interest. One such class of pathway is involved in the eugenol to vanillin bioconversion. Our goal is to develop an integral approach for identifying the topology of a reference or known pathway in other organism. We successfully identify the missing enzymes and then reconstruct the vanil...
متن کاملExtraction of Ferulic Acid from Agro-industrial Wastes and Evaluation of Bioconversion of Ferulic Acid to Vanillin by Streptomyces Setonii
Several agro-industrial wastes (as chestnut and pistachio shells, grass, leaf fruit, vine leaf, and, red and white grape stems) were evaluated to ferulic acid extraction. The chemical analysis of these raw materials shows a high content of xylan in pistachio shells (33%), following the biorefinery concept, this fraction can be used in xylitol manufacture. The lignocellulosic materials were subm...
