TL;DR: In this article, a method for preparing ferulic acid is described, which consists of slant culture, preparation of a seed culture solution, solid state fermentation, preparing of a crude enzyme liquid, enzymolysis and detection of the concentration of Ferulic acid.
Abstract: The invention discloses a method for preparing ferulic acid. The method comprises slant culture, preparation of a seed culture solution, solid state fermentation, preparation of a crude enzyme liquid, enzymolysis and detection of the concentration of ferulic acid. The ferulic acid is prepared with an Aspergillus niger TRIIM 3.00954 solid state fermentation enzyme production method, the conditions are mild, the environment is seldom polluted, the yield of products is high, few byproducts are produced, the production steps are simple, the production cycle is short, and the method is an economical and feasible ferulic acid production process with great industrial prospect.

TL;DR: In this article, an aspergillus cristatus feruloyl esterase gene provided by the invention can be used for in vitro generation of ferulic acid.
Abstract: The invention belongs to the field of genetic engineering, and in particular relates to an aspergillus cristatus feruloyl esterase gene as well as engineering bacteria and application thereof. The nucleotide sequence of the aspergillus cristatus feruloyl esterase gene is shown in SEQ ID No. 1. Feruloyl esterase encoded by the aspergillus cristatus feruloyl esterase gene has an amino acid sequenceshown in SEQ ID No. 2. The aspergillus cristatus feruloyl esterase gene provided by the invention can be used for in vitro generation of ferulic acid. Tests prove that the release rate of the ferulicacid in de-starch wheat bran suspension is 75.3%; the aspergillus cristatus feruloyl esterase gene enables the release rate of the ferulic acid to be much higher than other feruloyl esterase genes; therefore, a new enzyme source is provided for production of ferulic acid.
