Penicillin production Compare the growth phases that occur in a broth culture with what happens in an industrial chemo stat? Within an industrial chemo stat the production would be on a much larger scale and would be more efficient than that of a broth culture performed in the lab. The industrial process involves a batch fermenter that is enclosed making it easier to control the conditions within There are various things that are more controlled in the industrial chemo stat such as: 1) The temperature 2) The nutrients 3) The things contaminating the substance. Industrial production process: 1) Basic screening- to discover the optimum conditions of growth for some microorganisms an expert grows it in a small flask. They will consider its: …show more content…
Growth phases that occur in broth culture: Lag phase- this is stage one, the microorganisms have a slow growth as they have just been introduced to the growth medium. Log phase- this is stage two and is also known as the growth phase as the microorganisms reproduce at an exponential growth rates. Stationary phase- this comes next, the bacteria run out of nutrients and oxygen or are infected by their own waste resulting in a stunted growth which equals the death phase. The number of bacteria being produced is equivalent to that of the number which is being lost. Death phase-lastly comes the death phase or the decline phase in which the bacteria have reached their last stage due to nutrient fatigue and high levels of toxic waste causing them to eventually die out. How are optimum conditions maintained in a chemo stat? Chemo stats are tightly sealed, making the conditions within the chemostat easily controlled. This control is essential in the production of penicillin. The chemo stats conditions can be controlled such as the temperature the nutrients provided to the penicillin. The conditions within the chemo stat can be kept constant. And modifications can be made to the chemo stat to suit the substance and be put to its optimum
