You have to provide a little more information about the stuff.
Generally, chromatographic techniques can result in good separation over
only one or two steps but you have to work out the conditions. Is this
compound charged ? Polar ? Hydrophobic ? How big it is ? What's the
solubility in organic solvents ? etc. Do you have reliable (and simple)
methods for detection of the compound and evaluation of specific
activity ? What else is in your bacterial supernatant ?

Purification steps would strongly depend on the nature of the compound
and of the contaminants.
