Table 3 Techniques employed for the extraction of biopolymers
From: Biobased polymers of plant and microbial origin and their applications - a review
Extraction Techniques | Principle | References |
|---|---|---|
Mechanical Extraction | It employs physical methods like grinding and pressing to release polymers from plant cells or microbial biomass | Jha and Kumar 2019 [51] |
Enzyme-Assisted Extraction | Enzymes such as cellulose and lysozymes used to break down plant cell walls or microbial membranes, respectively. It leads to release of polymers | Nadar et al. 2018 [81] |
Microwave Assisted Extraction | Microwave radiation is used as heat source to disrupt cell wall | Mandal et al. 2007 [64] |
Non-thermal plasma | It is a pre-treatment technique in which partial voltage discharged to rise temperature of electron leads in reduction of recalcitrant nature of any hard material such as lignocellulosic material | Pereira et al. 2021 [91] |
Supercritical Fluid Extraction | Pressured carbon dioxide used to extract polymers from plant biomass or microbial cultures | Sapkale et al. 2010 [107] |
Deep eutectic solvents | Mixture of green solvents liked with hydrogen bonds with low toxicity and used to lower melting point of any mixture | Didion et al. 2024 [29] |
