Bioremediation of these chloroethenes can occur when other microorganisms at the contaminated site provide H 2 as a natural byproduct of various fermentation reactions.
2.
Dark fermentation reactions do not require light energy, so they are capable of constantly producing hydrogen from organic compounds throughout the day and night.
3.
The lactate-forming reaction generates cytosolic NAD +, which feeds into the this fermentation reaction serves to act as a buffer system for muscle acidosis.
4.
The fermentation reaction is undertaken by the family of lactic acid bacteria ( LAB ); " Oenococcus oeni ", and various species of " Lactobacillus " and " Pediococcus ".
