Hey Sir, thank you for going through this slowly and in great detail I really appreciate it. My lecturers over here in Ireland could learn alot from you!
Well the answer to the question is: the E.coli ( or other infectious microorganisms can be analyzed better in open system) because our body acts like an open system where nutrients are provided under aerobic conditions ( moreover E.coli growth rate can be analyzed optimally under aerobic conditions) so the answer would be : open systems
I have made a home scale very small Bioreactor for growing up yeast cultures of Kveik Yeast for drying and freezing yeast slurry , Its a 1 quart to 1/2 gallon reactor depending on which jar i use. Basically its a ball airlock lid( the kind for fermenting vegetables with a built in airlock) that i drilled a second hole in and put a stainless steel air stone that is hooked to an air pump and it sits on a Stir plate, so, if my understanding of the process is correct this would be a Very Basic Bioreactor. My issue is the feeding schedule for optimum yeast growth and how much sugar and nutrient i should be feeding it daily. I have Fermax yeast Nutrient and I am doing my Grow up with white Table sugar because its a cheap easy sugar source. I am building up a personal yeast bank of Kveik yeast strains for use in Home wine,beer and mead making. So My goal is the highest biomass I can achieve with the limits of my home made set up. My reactor it self is working so far I am just not sure on a rough estimate of how much sugar and nutrient to feed it daily. I dont have a super accurate Gram scale(yet) so I am using measuring spoons and cups at this point At the present time, I am doing roughly 1/2 teaspoon of yeast nutrient and about 1/4 cup of sugar daily in a 1 quart volume of water I was wondering how these amounts look and if i should change them, if so how much of each would you suggest. The yeast nutrient I have is a General purpose nutrient designed for home wine,beer and mead making. My sugar source is currently white table sugar due to price and ease of access. Any suggestions you can offer would be greatly appreciated.

Thank You Sir !! Very lucidly explained !! Love from India !!

Thank you! I was so confused about this tpc.
excellent explanatinos!
What is the right answer for the question in the of the video.

is it always possible to increase the growth rate of the bacteria? Also great video!
Only up
To a point. There are limits to growth rate based on the genetics/physiology of the strain.
perfect, that’s what I assumed. Thank you
