* '''Homofermentative bacteria''' convert glucose to two molecules of lactate and use this reaction to perform substrate-level phosphorylation to make two molecules of [[Adenosine triphosphate|ATP]]: | |||
:glucose + 2 ADP + 2 P<sub>i</sub> → 2 lactate + 2 ATP | |||
* '''Heterofermentative bacteria''' produce less lactate and less ATP, but produce several other end products (Examples include ''Leuconostoc mesenteroides'', ''Lactobacillus bifermentous'', and ''Leconostoc lactis''): | |||
:glucose + ADP + P<sub>i</sub> → lactate + [[ethanol]] + CO<sub>2</sub> + ATP | |||
* ''' ''Bifidobacterium bifidum'' ''' utilizes a lactic acid fermentation pathway that produces more ATP than either homolactic fermentation or heterolactic fermentation: | |||
:2 glucose + 5 ADP + 5 P<sub>i</sub> → 3 [[acetate]] + 2 lactate + 5 ATP | |||
