: The high cost of ferulic acid which is an ideal precursor for vanillin production leads to an increased budget for fermentation processes. In the current research, 162.5 ± 0.35 mg of ferulic acid was extracted from 100 g of peels that were used as a substrate for biovanillin production. To enhance biovanillin yield, the process parameters like substrate concentration, incubation period, pH, temperature, and agitation speed were optimized by RSM. The significantly highest amount of biovanillin, i.e., 4.2 g/L, was produced by biotransformation of 9 g/L of ferulic acid after 8 h of incubation time, pH 7, 30°C, and agitation speed of 100 rpm. These conditions can be further optimized on the bioreactor level to meet the market demand for biovanillin.All the authors mentioned in the manuscript have been approved for authorship, read and allowed to submit the manuscript, and given consent for submission and subsequent publication of the manuscript.
