| Summary: | Nowadays, palm oil mill effluent (POME) is the main water stream pollutant in Malaysia. This paper reviews
to development in the methods of bioethanol production from POME by acid-base-enzyme pretreatment and
hydrolysis processes. The methods currently used to treat POME are inefficient either of cost or in terms of
environmental preservation. Several techniques of pretreatment of POME are discussed, where the structure
of POME is breakdown and make it more accessible to the cellulase enzymes. Generally, hydrolysis process is
used as a mild acid-base-enzyme for monomeric sugar production from POME. The acid-base-enzyme
consists of H2SO4, NaOH and cellulase enzymes to run the hydrolysis process. In this paper, different
strategies are also described for hydrolysis processes, including concentrate acid hydrolysis, dilute acid
hydrolysis and enzymatic hydrolysis. In addition, the production of bioethanol by fermentation of sugars
obtained from the hydrolysis process are discussed and it points out some key properties that should be
targeted for cost effective and innovative pretreatment processes.
