We describe the production and use of an extract obtained fromspp., preferably from bananas, in the promotion of growth of Gram-positive bacteria such as lactic acid bacteria. The extract is also useful for growth enhancement of environmentally-stressed Gram negative bacteria. Fermented foods containing such extracts are also described.

Bacterial growth enhancer

A bacterial autoinducer and method for isolating and purifying a bacterial autoinducer form a sample comprising the steps of collecting a sample containing the autoinducer, fractionating the sample to isolate fractions corresponding to molecular weights of approximately 300-1500 Dalton, and eluting the isolate on an anion-exchange chromatographic column and selecting the faction containing the autoinducer.
