Production Process in Industrial biotechnology

1. BIOPOLYMERS NPH

2. BIOPOLYMERS Introduction composition Types of biopolymers Biological functions Applications

3. Introduction Polymers that are produced by living organisms. They are distinguished from synthetic polymers, which are made through chemical synthesis. Biopolymers are crucial components of living organisms and play diverse roles in biological systems

4. Biopolymers are composed of monomeric units linked together through covalent bonds. These monomeric units can be amino acids, nucleotides, monosaccharides, or fatty acids, depending on the type of biopolymer. There are three main classes of biopolymers, classified according to the monomers used and the structure of the biopolymer formed: proteins, nucleic acids, and polysaccharides.

5. TYPES OF BIOPOLYMERS PROTEINS fabrication of tissue-engineering constructs, therapeutic molecule delivery carriers, emulsifiers, food packaging materials. NUCLEIC ACID polymers composed of nucleotide monomers linked together by phosphodiester bonds. carry genetic information and are involved in the storage, transmission, and expression of genetic information POLYSACCHARIDES complex carbohydrates composed of monosaccharide - glycosidic bonds.

6. Lipids: Diverse group of biopolymers that include fats, oils, phospholipids, and steroids. They are hydrophobic molecules that serve as energy storage molecules, structural components of cell membranes, and signaling molecules .

7. Biological Functions : Provide structural support to cells, tissues, and organs. Proteins, particularly enzymes, catalyze biochemical reactions in living organisms. Enzymes facilitate chemical reactions by lowering the activation energy required for the reaction to occur Genetic Information Storage and Transmission Energy Storage and Metabolism. (glycogen, starch,….)

8. Applications: Biomedical – drug delivery system, tissue engineering scaffolds, and wound dressings Food and Packaging - Biopolymers like starch-based bioplastics are used as alternatives to traditional petroleum-based plastics in food packaging and disposable utensils. Agriculture - biodegradable mulches, soil conditioners, and crop protection agents.

9. BIO PRESERVATIVES NPH

10. BIO PRESERVATIVES Introduction Types of bio preservatives Mechanism of action Applications

11. Introduction: natural preservatives or bio-based preservatives. Inhibits microorganisms to extend shelflife

12. Types of Biopreservatives : Herbs and Spices Organic acids Bacteriocins(peptidic toxins) Enzymes

13. Mechanism Of Action Antimicrobial Compounds : disrupt microbial cell membranes, inhibit essential enzymes, or interfere with cellular processes pH regulation : Organic acids, such as acetic acid, lactic acid, and citric acid, lower the pH of the environment, creating conditions unfavorable for microbial growth. Enzymic Activity : proteases and lipases, can degrade microbial cell walls or membranes, leading to cell lysis

14. Applications: Food preservatives Cosmetics Pharmaceuticals Tissue engineering Medical device coating etc …
