Effect of Rhizopus Oryzae Fermentation on Kenaf-based Polylactic Acid’s Monomer

Kenaf biomass is the potential as raw materials used to produce polylactic acid’s monomer which is lactic acid via fermentation by Rhizopus oryzae. Kenaf biomass’ structure is complex due to its lignin and cellulose content. This matter had encouraged it to undergo pre- treatment process as the i...
