**4. Biopolymer and industrial applications**

Biodegradable polymers used widely in industries such as textiles, packaging, fast-food container and packaging, paper coating, agriculture mulch films, medical products, tubes, lawn and garden waste bags, disposable wipes, erosion control, biologically-based resins, car parts, glass fibers agents, as well as coatings and adhesives [3, 47, 48]. Various blending ratios of regular and waxy corn starches with copolyester were extruded into loose-fill foams [49]. PCL (polycaprolactone) are used to made spun fibers, scaffold fibroblasts and myoblasts for soft tissue engineering [15]. Natural biopolymer-based films and the packaging materials have been studied [50, 51]. Ochratoxin-A as well as amycotoxinis a common food contaminant that enters the human body through the consumption of improperly stored food products and can be used as a electrochemical biosensor [52]. Polysaccharide and protein based biopolymers can be utilized as coatings to enhance the fruits and vegetables quality; The medical biopolymers applications are [53] include extracorporeal (i.e., artificial kidneys, fluid lines, dialysis membranes, catheters, wound dressings, artificial skin, etc), temporary implants (i.e., degradable sutures, as well as arterial stents, tissue/cell transplants' scaffolds, temporary vascular grafts, etc), and permanently implanted devices. Biopolymer fibers with typical morphology find applications in bone tissue engineering [54] and as a degradable nano-fiber [55]. Wound dressing materials must be biocompatible, anti-bacterial, prevent infection, and provide a suitable moist environment [56, 57]. Chitosan complexed with gelatin has been useful as a surgical dressing at a ratio of 3:1 (chitosan:gelatin), as it

stimulates hemostasis and accelerates tissue regeneration [58, 59]. Their fabrication provides appropriate biodegradability and excellent cell adhesion activity, both useful in making a novel and elastomeric bioactive vascular tissue scaffold [60]. A fiber based on chitosan and starch which was loaded with drug has had successful applications in drug delivery [61]. Various fabrication methods have been employed in the preparation of bio-polymeric membranes and a film-casting process [62, 63].
