Optimisation of the hydrolysis of oil palm empty fruit bunch to glucose using RSM

There is a growing incentive to identify alternative renewable energy sources. Among the sources, grains, plant matters (biomass) and their wastes are commonly been used for biofuel production due to their sustainability. Oil palm empty fruit bunch (EFB) is a type of lignocellulosic waste from palm...
