Fungal chitosan for potential application in piezoelectric energy harvesting: Review on experimental procedure of chitosan extraction

Fungal chitosan is one of the piezoelectric biomaterials that can be used in energy harvesting. biomass offers a sustainable source for chitosan, as an alternative to crustacean-based chitosan. However, fungal yield relatively lower than other conventional sources Therefore, this study aims review different experimental procedures chemical extraction from biomass. The selection most effective method using Preference Ranking Organization Method Enrichment Evaluations and Geometrical Analysis Interactive Decision Aid (PROMETHEE-GAIA), systematic multiple criteria analysis based on ranking section alternatives (i.e. methods). PROMETHEE-GAIA was performed critical comprehensive discussion paper. showed microwave-assisted organic acid-alkaline treatment highest due positive response yield, degree deacetylation, toxicity temperature.
