Two polyphenoloxidases (PPO ] and PPO III, EC 1,10.3,1) were extracted and partially purified from sago palm pith by hydroxylapatite chromatography, DEAE-cellulose chromategraphy and gel filtration. Both purified isozymes gave a single activity band on polyacrylamide gel electrophoresis. The rno]ecular weights of both enzymes were estimated to be 40,OOO. Thev had the same pH optima of 6,5 but ...

Enhancement of pullulanase production by Raoultella planticola DSMZ 4617 using optimized medium formulation was investigated in batch fermentation using 500-mL shake flask. The fermentations were carried out, firstly, to search for a suitable cultivation medium for enzyme production and followed by the evaluations on the influence of carbon and nitrogen sources and also initial culture pHs on t...

The aim of the present study is to develop a novel biomaterial from natural resources which can be used for various biomedical applications. In this work, composite films containing soya protein (SY) and sago starch (SG) were prepared by solvent casting methodology; these films were cross linked with glutaraldehyde to improve their mechanical properties. The films prepared were characterized fo...

Packed bed cultivation systems have potential for widespread application in solid-state cultivation (SSC), but they are poorly characterized. The effects of particle size and substrate loading on the growth of Rhizopus oligosporus on sago-beads in packed bed bioreactors were investigated. Pressure drop and protein were monitored as indicators of fungal growth in cultivations performed in a larg...

The major restriction of sago palm plantation is the long maturation period for starch extraction. As such, alternative commodity has to be identified increase commercial value especially from by-product. Sago frond been harvested have numerous advantages as an substrate production biomaterial and biofuel such lactic acid bioethanol. This study focuses on effective approach maximise concentrati...

This study examines the consequences of various agrarian policies and development programs on Kamoro community in Mimika Regency, Papua Province. As a result FI Mining activities, people, who were originally nomads their customary lands, relocated to permanent settlement where they introduced intensive farming systems, one which was Sago Planting Hamlet (SPH/DST) Program that brought modern sag...

Abstract Cement is a key material in the construction industry. However, this widespread use adversely affects environment. The replacement of cement with waste materials, mainly agricultural wastes, can reduce impact environmental pollution and result sustainable construction. Sago fine (SFW) fibrous residue from sago milling operations where physical treatment has been made. This study used S...

Land use affects changes in peak discharge so that it has the potential to cause or prevent flooding. Sago morphological characteristics have absorb more water. This study aimed determine magnitude of change upstream watershed after sago planting. Observations were made on three growth phases palms (initial, middle, and mature phases). The research stages included calculating runoff coefficient...

istered morning and evening, with milk and sago as diet. The patient, up to 25th, did not complain of any pain or uneasiness in the head, nor had he much fever. He did not show any symptom of injury to the internal organs. On the morning of the 25th, slight paralysis (affecting both motion and sensation) of the left side of the face was noticed (side corresponding to the wound), which gradually...

Changes in the physicochemical properties of wheat, sago, tapioca and potato starches were studied after heating for 1 hour at 100oC, 110oC, and 120oC and for 2 hours at 120oC. These properties were characterised through the swelling behaviour of starch granules, amount of carbohydrate materials leached from the granules, starch paste retrogradation rate and gel strength. For all starches excep...
