Advances in Sago Research and Development
known as non-trunking sago palm. The non-trunking phenotype of Metroxylon sagu eliminates
the economical value of the plant and this is one of the major concerns of sago plantation till
this day. Our research group has embarked on efforts to identify molecular factors that
contribute to the differences between two groups of sago palm including their proteomics. Part
of the work involves comparative proteomics analysis of trunking and non-trunking sago palm
leaf. Prior to that, protein extraction and preparation, protein separation by one- or twodimensional
electrophoresis (1-DE or 2-DE, respectively), followed by matrix-assisted laser
desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) were described. Using
2D gel electrophoresis, MALDI-TOF and RP-HPLC, we have identified several proteins that
showed differences in level of protein expression between the two groups of sago palm.

The plump, yellowy-cream body with soft-ridged texture of the larva of Rhynchophorus
ferrugineus, locally known as sago worm, had been the mainstay of the diet of ethnic
communities such as Melanau and Dayak in Malaysia as their source of protein, fat and
carbohydrate. Today it has become a delicacy. The process that has been developed, converting
the larvae to powder form using steaming, homogenizing and air-sprayed drying method is able
to reduce the original fat content of 50% to below 30%, increasing carbohydrate content from
15% to 30% while maintaining protein content of 24%. It is also rich in minerals such as
potassium, calcium, magnesium, zinc, phosphorus and iron, as well as various vitamins.
Ferrugineus sago powder can be used to make into various form of energy food.

Fuel ethanol production has become one of the major focuses in scientific research since the
energy crisis of 1970. The production costs are a major issue for the production of fuel ethanol.
In this study, hydrolysed sago starch has been used as a substrate which is more economical
compare to commercialized glucose. Thermotolerant yeast strain which is Candida tropicalis
