2. What is Industrial Microorganism? Industrial microorganism is the branch of biotechnology that applies in industry for creating industrial products in mass quantities. Industrial biotechnology uses microorganisms to make bio based products such as chemicals , food and feed , detergents , paper and pulp , textile and bioenergy with less waste generation & reduce energy consumption.

3. Properties of useful industrial microorganism Produces spores can be easily inoculated Grows rapidly on a large scale in inexpensive medium Produces desired product quickly Should not be pathogenic Amenable to genetic manipulation

4. Metabolic products Traditionally , microbes used in fermentation processes have been naturally occurring strains of bacteria and molds that carry out a specific metabolic reaction on a substrate. In the last 25 years, industrial microbes have increasingly been mutant strains engineered to selectively synthesize maximized amounts of various metabolic intermediates. The products of an industrial microbial process can be divided into two broad classes: Principal Metabolites Secondary Metabolites

5. Examples of primary metabolites & secondary metabolites

6. Microbe Types Industrial microorganisms generally fall into one of the following categories: Bacteria Algae Fungi Yeasts Viruses

7. Industrial important bacteria Among the earliest life forms, bacteria are prokaryotes (lacking defined nuclei) with staggering metabolic diversity. Industrially, many different bacterial species are used in a wide range of processes from biofuels to pharmaceuticals Lactococcus : used as starter in yogurt manufacture , produces copious amount of lactic acid Streptococcus : used in yogurt manufacture Enterococcus : used in monitor water quality Pediococcus : Spoils beer required in special beers such as lambric beer drunk in parts of belgium Leuconostoc : Involved in pickling of vegetables , produce dextrans from sucrose. Lactococcus Streptococcus Enterococcus Pediococcus Leuconostoc

8. Lactic acid bacteria Lactic acid bacteria are rods are cocci Its is divided into two major groups: homofermentative heterofermentative Desirable characteristics of lactic acid bacteria as industrial microorganisms. Lactobacillus delbreuckii : ferment sucrose Lactobacillus helveticus : use lactose and glucose Lactobacillus lactics : ferment glucose , sucrose and galactose Lactobacillus pentosus : ferment sulfide waste liquor

9. Actinobacteria Industrial importance are: Streptomyces : many antibiotics as well as non-anti-microbial drugs have been obtained. Erythromycin , Neomycin , Tetracycline and Cefoxitin. Corynebacterium spp : secreters of aminoacid Clostridium spp : convert sugar into alcohol Bacillus spp : enzyme production , to kill insects. Actinobacteria

10. Industrial important of fungi Fungi are used in industries for manufacturing large varieties of useful materials for mankind such as metabolites , enzymes and food. The filamentous fungi are used in many different process in food industry for manufacture of different metabolites and variety of other processes.

11. Fungi in drug industry Penicillin : Derived from Penicillium chrysogenum was first used successfully to treat an infection caused by a bacterium. Cephalosporin’s : The original fungus found to produce the compounds was a Cephalosporium Penicillium griseofulvin: Griseofulvin is fungi static , rather than fungicidal.It is used for the treatment of dermatophytes, as it accumulates in the hair and skin following topical application Cyclosporine A It is a primary metabolite of several fungi , including Trichoderma polysporum and Cylindrocarpon lucidum Gliotoxins Produced by many fungi including Aspergillus fumigatus

12. Algae The term algae refers to an extremely diverse group of eukaryotes (organisms with defined cellular nuclei), strains of which are used industrially in the production of Biofuels, such as biodiesel, Wastewater treatment, Among other uses

13. a)Chlorella Chlorella get popularity after use in space research center and nuclear submarine to generate oxygen. It is also famous for it’s nutrient value. It contains 30% carbohydrate, 30% protein, 15% lipids, and also vitamin B and other nutrients. Which are essential for human beings as well as animals. (b). Laminaria It has 57% carbohydrate and is mostly used to prepare a popular dish known as  ‘ Kombu ’. (c). Chondrus It is an Irish moss and is cooked with milk and prepared in a popular dish known as blancmanges. (d). Porphyria It is a seaweed of Rhodophyceae which contains 45% carbohydrate, 35% protein, and vitamin B. It is used to prepare a popular dish in japan named ‘Asakusa-Nori’(Porphyra tenera). Industrial important algae

14. (e) Spirulina Spirulina is a blue-green algae that contains 60% protein, vitamin, and unsaturated fatty acid. In India Spirulina is available as a tablet. (f). Spirogyra In south India, it is used to prepare a popular dish known as green laver. Spirogyra is commercially cultivated in Japan, Korea, and Taiwan, such as Ise Bay. (g). Ulva In Japan, it is used as a salad. (h). Nostoc In China, nostoc is used to prepare soup by boiling it

15. Algae

16. Yeast Likely the oldest domesticated microorganism, yeast is a single-celled eukaryote best known industrially for producing ethanol from sugars by fermentation.

17. Virus Viruses are employed in the production of different vaccines used medically to prevent viral diseases or infections.  Viruses are sources of important enzymes such as reverse transcriptase used in molecular biology or biotechnology processes for the production of important drugs and other pharmaceuticals Viruses can act as gene vectors for the useful production of useful proteins such as interferons

18. Organisms and method for amino acid production

19. Some important microbial enzymes and their application

20. Sources and name of common antibiotics
