JUST WHY IS THE RUSH TO USE THE FERMENTOR?

We must remember it took perhaps thousands of years for the human civilizations in various countries to discover the secret arts of fermentation until they have perfected the art of producing wine. The science and technological input into the field of fermentation technology have to await the discovery of Pasteur, Fleming and even the World Wars to push it forward to what it is almost today. In fact the structure of fermentor hardware has really remained unchanged even though the use of sensors, computers and engineering has influenced it. The increase in fermentation productivity is more from improvements in strain development
However, nowadays with the prolific offering of degrees in biotechnology and subjects like fermentation technology, the understanding and transfer of this technology seems to be very fast or take a very short learning curve. Having a degree in this field does not always automatically a fermentation technology expert. Especially in the field of fermentation technology more is learnt through trial and errors or through experience with the operation of the fermentor.
The true understanding of fermentation technology is not merely by reading books or lectures. Such approach will nly gives you the superficial scraping on the surface of the subject. This is often reflected by the students in only operating a standard lab model fermentor by following the attached manual or instructions. The manual does not teach you the way one should carry out any fermentation work or even in the design of experiments in fermentation.
It is at this point where the teacher or lecturer of the course must be able to teach the students the proper way to use and carry out the fermentation experiment
I have observed that most courses offered in fermentation technology stressed mainly in the operation of the fermentor according to the manual but failed badly in teaching the students how to exploit the fermentor as a powerful tool in research or teaching
Various upstream, downstream procedures, standard operating methods and validation are not executed. Practical fermentation technology by McNeil and Harvey should be a good starting point in understanding some aspects of the fermentor
