<P><B>Abstract</B></P> <P>The bulk availability of banana waste in the world has made a move towards the development of alternative novel renewable sugars in present study as the pressed juice from banana frond and pseudostem was found to contain high level of renewable sugars such as glucose, sucrose and fructose. By using a simple sugarcane press, the glucose content in the banana frond juice was 16.6 g/L, which accounts for 55% of the total fermentable sugars. From the results, the lipase production reached &sim;200 U/mL in medium comprising banana frond juice and banana pseudostem juice, comparable to basal medium with glucose (206.3 U/mL) as carbon source in basal media. As banana pseudostem possesses high content of starch, microwave heating pretreatment showed 36% enhancement of glucose content (10.4 g/L) in juice as compared to direct pressed juice (7.78 g/L). This result indicates that banana waste juice can be used as an alternative fermentable carbon source for lipase production and has potential as a fermentable carbon source.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Banana waste juice contains novel renewable sugars as fermentation substrate. </LI> <LI> Direct pressed banana frond juice contains high glucose content which was 16.6 g/L. </LI> <LI> Microwave heating enhanced extraction of fermentable sugars in pseudostem juice. </LI> <LI> Lipase production by <I>E. coli</I> an example of banana waste juice utilization. </LI> </UL> </P>
