Summary Introduction
Syntrophic bacteria comprise an important group of organisms which play an important role in the conversion of organic compounds to methane. Syntrophomonas and Syntrophobacter are important and common examples of syntrophic bacteria which belong to Syntrophs. Species of Syntrophomonas can use fatty acids up to the length of C18 and can also use few types of unsaturated fatty acids. Syntrophomonas wolfei is a species which can oxidize fatty acids up to the length of C4 to C8.

The chemical reaction equation for the conversion of ethanol (C2H5OH) to acetic acid (CH3COOH) is: C2H5OH + O2 → CH3COOH + H2OIn a vinegar production industry, acetic acid is produced from ethanol during the growth of the bacterium Acetobacter aceti, whose cellular composition is CH1,8O0,5N0,2. The biomass yield from substrate is 0.14 g/g, while the product yield also from substrate is 0.92 g/g. Ammonia is used as a nitrogen source. Based on this information, answer:
(a) What is the oxygen demand for acetic acid production in this crop?(b) What are the cooling requirements of a bioreactor containing 3000 L of ethanol (ρ = 789 kg/m³), to be completely converted into acetic acid?
In the microbial community of the bovine rumen, the actual AG value has been calculated for glucose fermentation to acetate: CaH12O6 + 2H20 → 2CH:03 + 2H+ + 4H2 + 2CO;
AG =-318 kJ/mol
If the actual AG for ATP formation is 44 kJ/mol and each glucose fermentation yields four molecules of ATP, what is the thermodynamic efficiency of energy gain? Where does the lost energy go? Why is the AG not 31 kJ/mol?
The table below provides kinetic information when ADH is reacted with ethanol alone, NAD+ alone, and ethanol with NAD+
