The invention discloses a method for performing pretreatment and biotransformation by adding an acidic reagent in a lignocellulose raw material densification process. The method comprises the following steps: adding the acidic reagent and water into a lignocellulose raw material, performing uniform mixing, and performing densification treatment; or pretreating the lignocellulose raw material by anacid method, then performing densification treatment to obtain densified lignocellulose, then directly performing biotransformation, or performing biotransformation after subsequent selective pretreatment to produce a target chemical. The acidic reagent is added in the lignocellulose raw material densification process to destroy the original structure of lignocellulose, so that the mild pretreatment process of the lignocellulose raw material is realized in the subsequent transportation and storage processes, and the severity of further pretreatment is reduced. Compared with a loose raw material, obtained lignocellulose particles are higher in density and convenient to transport and store, the pretreatment cost is reduced, and the yield of a target product is higher in biotransformation ofthe acidified and densified lignocellulose.
