Hello, I'm Shri Shankari and I'm 17 years old.
I have chosen a biological experiment to be performed in zero gravity.
My experiment is about the production of single cell protein...
...from the bacterium Bacillus subtilis.
Bacillus subtilis is a saprophytic bacteria...
...that can be grown on dead decaying organic matter.
When it is grown in zero gravity...
...it shows a shorter lag phase and a higher growth rate.
Obviously, it can be made to produce a higher biomass yield...
...which can be used as single cell protein known as microbial proteins.
The bacterium Bacillus subtilis...
...can be made to produce microbial biomass...
...in a fermenter or a bioreactor...
...at an optimum temperature of 23 degree Celsius...
...using low cost substrates such as cellulose or waste from coffee production.
Dry cells from this bacterium can be used as a supplemental food...
...for human consumption and also as a feed for animals.
Expected results. If this happens in microgravity...
...then there will be a higher production of single cell protein...
...which is of commercial value and it is also a rich source of proteins...
...vitamins, minerals, amino acids and crude fibers.
Thank you.
