Simply so is E coli positive for indole test? Indole Positive Bacteria Bacteria that test positive for cleaving indole from tryptophan include Aeromonas hydrophila Aeromonas punctata Bacillus alvei Edwardsiella sp Escherichia coli Flavobacterium sp Haemophilus influenzae Klebsiella oxytoca Proteus sp.
Biochemical Test of Escherichia coli (E. coli) Microbe Notes
The indolemediated reduction in cytoplasmic pH may explain why indole provides Ecoli with a degree of protection against stresses including some bactericidal antibiotics Bacterial cells are.
Biochemical Tests For Escherichia coli (E. coli
Our lake has been tested for EColi and the results were given as such 1 >80 2 5 3 5 and 4 55 I assume they did 5 separate tests but did not explain if these are high or low and whether our is contaminated to the point that we cannot swim in or uuse its water to take showers or let the dogs in it since they drink the water.
Indole Pulse Signalling Regulates the Cytoplasmic pH of E
Indole production is often used to differentiate E colifrom other indolenegative enteric bacteria because 96% of E coliare indole positive whereas many enterobacterial species are negative in the indole reaction.

Wikipedia Indole test
Indole is a signalling molecule secreted by over 85 species of bacteria including Escherichia coli [1] It is produced by the enzyme tryptophanase (TnaA) that converts tryptophan into indole pyruvate and ammonia [2] E coli makes very little indole during exponential growth.
