what bacteria used for lactose fermentation?
Was a durham tube used for lactose fermentation?
Which test had these purposes:
ferment specific sugars (glu, lac, suc)
produce gas (CO2)
produce hydrogen sulfide (H2S) by reducing sulfur
Which test had this purpose:
to determine if microbes reduce sulfur-containing compounds to sulfides during the process of metabolism & to determine if a microbe is motile
Which test had this purpose:
To determine if a microbe ferments the carbohydrate lactose and to determine if they produce gas as a by-product of carbohydrate fermentation

What test purpose is this:
To determine if a microbe can split indole from the amino acid tryptophan
What test is this:
Media = 1% tryptone broth (Not SIM agar like your lab manual says)•
Enzyme = Tryptophanase
•Indicator = Kovac’s reagent
What test is this:
selects for organisms found in the family, Enterobacteriaceae, and differentiates between members of that family that can produce tryptophanase & those that cannot
What test and what are results?
