Microbial synthesis of poly(e-lysine) and its various applications

This review article deals with the microbial synthesis, physiochemical properties, and potential applications of poly-e-lysine (e- PL), which is a naturally occurring biomaterial that is water soluble, biodegradable, edible and non-toxic toward humans and the environment. The potential applications of e-PL as food preservatives, emulsifying agent, dietary agent, biodegradable fibers, highly water absorbable hydrogels, drug carriers, anticancer agent enhancer, biochip coatings in the fields of food, medicine, agriculture and electronics are also discussed in this review.
