3.0 BIOREACTORS FOR PLANT CELL TISSUE AND ORGAN CULTURES fly Shinsaku Takayama) 3.1 Background of the Technique-Historical Overview HaberlandtL'] first reported plant cell, tissue, and organ cultures in 1902. He separated plant tissues and attempted to grow them in a simple nutrient medium. He was able to maintain these cells in a culture medium for

2.1 The Microbiological Laboratories Isolation of organisms for new products normally does not occur in laboratories associated with production cultures, however, production (mi￾crobiological) laboratories frequently do mutation and isolation work to produce strains with higher yields, to suppress a by-product, to reduce the formation of a surfactant, to change the physical properties of the broth to facilitate the product recovery

When designing a fermenter, one primary consideration is the removal of heat. There is a practical limit to the square feet of cooling surface that can be achieved from a tank jacket and the amount of coils that can be placed inside the tank. The three sources of heat to be removed are from the cooling of media after batch sterilization, from the exothermic fermentation process

A common problem for a biochemical engineer is to be handed a microorganism and be told he has six months to design a plant to produce the new fermentation product. Although this seems to be a formidable task, with the proper approach this task can be reduced to a manageable level. There are many ways to approach the problem of optimization and design of a fermentation process
