【 摘 要 】

The feasibility of lignocellulosic pretreatment is a key step for the production of biorefinery product, since the breakdown of cell walls can increase the access to sugars present in cellulose and hemicellulose while the aromatic compounds released from lignin. Cacao pod is an example of major agricultural residue, which contains high lignocellulose consisting of cellulose 36%, hemicellulose 38% and lignin 15%. In this study, the eficacy of biological pretreatment degrade lignocellulose from cacao pod using microbes brown rot (Serpula lacrymans) and white rot (Schyzophyllum commune) has been examined and compared. The addition of precursor CuSO4 to the media was also tested to identify whether this chemicals had an effect on increasing the ability of fungi to degrade lignocellulose. The results revealed that between S.lacrymans dan S.commune showed different pattern in degrading lignocellulose of cacao pod as indicated by pH, weight loss, total reducing sugars and phenols released. Compared to white rot fungi S.commune, the brown rot fungi S.lacrymans produces higher levels of sugars and phenols released from cacao pod. The different concentration of CuSO4 added on media also emphasised the distinct change on chemicals released from degradation of lignocellulose of cacao pod.
