<P>The method of plant lactobacillus fermentation was used to get rid of protein and extract chitin of the abandoned shrimp shell. The optimal fermentation technology was studied. The results suggested that the best fermentation process was as follows:fermentation temperature was 38°C, fermentation time was 96 h, glucose quantity concentration was 10%, solid-liquid ratio was 1.0:2.5 (m/v, g: ml), fermentation starting pH was 6.5.Using the optimal tecnology, the chitin yield was up to about 13.5%. This research has remarkable economic benefits and social benefits, and has good application prosptect.</P>
