“…Chitin (CT) is mainly found in crustacean shells and cell walls of fungi and it is the second most abundant polysaccharide on earth after cellulose. CT has received much attention because of its antibacterial activity, low toxicity, and excellent biocompatibility, medical treatment, and antibacterial properties . Although it is widely available, its poor solubility in water and almost all common organic solvents has limited its application.…”

To improve the bioactivity of chitin (CT), novel N-quaternized (QCT), and N-diquaternized (DQCT) CT derivatives are synthesized through a series of reactions from CT. The derivatives are characterized using elemental analysis, FTIR, and 13 C NMR. In addition, the inhibitory effects of the compounds against three fungi (B. cinerea, F. oxysporum, and P. asparagi) are tested. The inhibitory indices of CT, QCT, and DQCT are 12-15%, 63-73%, and 74-89%, respectively, at 1.0 mg mL À1 . The antifungal activities are in the order of DQCT > QCT > CT, which correlated with the number of quaternized groups. Based on these results, it is concluded that the antifungal activity of CT is improved by the introduction of quaternized groups on CT backbone.

Shell biorefinery, referring to the fractionation of crustacean shells into their major components and the transformation of each component into value-added chemicals and materials, has attracted growing attention in recent years. Since the large quantities of waste shells remain underexploited, their valorization can potentially bring both ecological and economic benefits. This Review provides an overview of the current status of shell biorefinery. It first describes the structural features of crustacean shells, including their composition and their interactions. Then, various fractionation methods for the shells are introduced. The last section is dedicated to the valorization of chitin and its derivatives for chemicals, porous carbon materials and functional polymers.

Reviews on biotechnological chitin recovery from crustacean waste and other sources acknowledge. Most of the reviews conclude that although important results on chitin recovery have been achieved, there is still a need for better approaches to improve operational conditions of deproteinization and demineralization processes, such as time, carbon source, pH (initial and during fermentation), volume of inoculum, temperature, among others, in order to apply at industrial level, a bioprocess commercially and environmentally cost/effective viable. The present review aims to gather the most updated available information about research on biotechnological methods to recover chitin from crustacean waste, studied during the past 10 years, focussing on conditions applied to deproteinization (DP) and demineralization (DM), particularly on bioprocessing times and microbial species.
