Microbial fermentation

Question 1

What is fermentation

Answer 1

Anaerobic catabolism of an organic compound which serve as a e donor and acceptor( driven anerobically which breaks down primary product

Question 2

fermentation pathway of clostridium propionicum

Answer 2

1. lactate acid is oxidized to pyruvate
2. pyruvate is oxidized to acetly-CoA and CO2
3. acetly-CoA is converted via acetly-P
   4) to aceate and ATP
   5) lactate acquires a CoA from propionly-CoA
   6) lactly-CoA is dehydrated to acryly-CoA
   7)acrylyl-CoA is reduced to propionly-CoA

Question 3

Lactate fermentation

Answer 3

Homo and heterofermentaive process
aerotolerant anaerobs which ferment glucse to lactate as the majour product of fermentation

Question 4

Mixed acid fermentation

Answer 4

produces succinate, lactate, acetate, etoh, CO2 and H2 via process seen in facultative anaerobes

Question 5

what are the main type of fermenting bacteria

Answer 5

Facultive anaerobes

Question 6

what is acetogensis

Answer 6

the production of ATP via fermentation of acetate

Question 7

what is the anerobic food chain

Answer 7

fermenation of amino acids carbohydrates and purunes to organic acids and alcholos this si followed by conversion to CO2 and H2 aswell as acetat
methogens then covert these compounds to CH4 and CO2
