As the fermentation process is operated continuously, the operator should have more knowledge about fermentation, microbial behaviour and growth. Fermentation can be defined as a metabolic process in which cheap raw materials such as sugar or carbohydrates are converted into economically important products like acids, gases and alcohols by micro-organism. They are: (i) Inoculum production, (ii) Preparation of medium, (iii) Fermentation process, (iv) Harvest and recovery. Hello, my name is James Lawrence from the Department of Biochemical Engineering at University College London. I'm going to be talking to you through this video on microbial fermentation processes and bioreactor design. Aerobic Fermentation: A fermentation process carried out in the presence of oxygen is called as aerobic fermentation. This process can be used as a teaching tool for the inexperienced fermentation student or researcher in the fields of bioprocessing and bioreactors. Preliminary Investigations 2. Introduction to Fermentation 2. During fermentation the most harmful bacteria that can grow O is of the genus Acet bacter. The fermentation process showed unique characteristics by which it generates energy in the absence of oxygen. ADVERTISEMENTS: Here we detail about the six important parameters of fermentation biotechnology. Introduction to Fermentation Process: Fermentation term for the first time was coined by Louis Pasteur for a phenomenon of bubbling of sugar solution. 4 The production of alcoholic beverages. The fermentation phase of the design utilizes a series of fibrous bed reactors and two different strands of Clostridium bacteria for each stage. The fermentation of a huge culture is a time-consuming process. Fermentation systems may be liquid, also known as submerged or solid state, also known as surface.Most fermentors used in industry are of the submerged type, because the submerged fermentor saves space and is more amenable to engineering control and design. Lecture 1 fermentation biotechnology - SlideShare Fermentation Technology, 2. ndnd ed.,ed., Butterworth Heinemann, Heinemann, Oxford, 2000. Fermentation in terms of biochemistry and physiology:-Fermentation is now defined as a process of energy generation by various organisms especially microorganisms. It needs to be contamination-free until the process is complete. During the process there is neither any addition nor any withdrawal of nutrients. Feedstocks for Fermentation Processes 5. All the fermentation processes are not aseptic, but contamination by microbes need to be maintained minimum by carried out media boiling and pasteurization Or else fermentation medium will be covered by fast growing contaminant which do not allow proper fermentation process due to use of nutrient by contaminant Modern fermentors are usually integrated with computers for efficient process monitoring, data acquisition, etc. Dual or Multiple fermentation process; In this fermentation process, two or more types of micro-organisms are used.. Solid State Fermentation (SSF) Solid State Fermentation (SSF) is a fermentation method used by several industries like the pharmaceuticals, food, textile etc., to produce metabolites of microorganisms using solid support in place of the liquid medium. 4 Separation and purification of end products.
