Abstract

The large amount of shrimp waste produced every year contains a large amount of natural cellulose material (chitin), which causes a waste of resources. This paper uses co-fermentation to recover chitin from shrimp waste and compares it with other common methods (monomicrobial fermentation, two-step fermentation). By adjusting the inoculation ratio of the Bacillus zanthoxyli strain and Streptococcus thermophilus strain, the ratio of glucose to sucrose, temperature, and pH, we obtained chitin with DP% and DM% of 68.89% and 83.80%, respectively. Through a comparative analysis, we found that DP% and DM% of chitin extracted by co-fermentation were more balanced. The chitin improved by the small-size shrimp shells was DP%, DM% and DA% of 83.76%, 91.48% and 93.47%, respectively, which proved the potential of obtaining the high quality of chitin using the co-fermentation method. Co-fermentation is a viable alternative biological fermentation method for extracting chitin from shrimp waste.
