摘要: Bacillus aryabhattai BA03, a strain isolated in our laboratory, has interesting properties related to the production of natural aromas and flavors. Specifically, we have found that it was able produce vanillin from ferulic acid (FA). Furthermore, this produces high amounts 4-vinylguaiacol only 14h, being intermediate metabolite observed process. FA is an inexpensive feedstock for value-added compounds when extracted lignocellulosic wastes. In study, optimized operational conditions (temperature, pH agitation), medium composition bioconversion technology (batch or fed-batch) vanillin. fed-batch process conducted with just one additional supplementation after 24h, maximal concentration (147.1±0.9mg/L) 216h (QV=0.681mg/Lh; YV/fFA=0.082mg/mg) degrading 90.3% FA. view data, postulate BA03 carries out decarboxylation as metabolic pathway.
