Utilization of waste crab shell (Scylla serrata) as a catalyst in palm olein transesterification.
Aquaculture activity has increased the population of crab, hence increasing the generation of related wastes, particularly the shell. In addition, the number of molting process in crabs compounds further the amount of waste shell generated. As such, in the present work, the application of the waste crab shell as a source of CaO in transesterification of palm olein to biodiesel (methyl ester) wa...

Sub-adults and juveniles were 28 % and 4.5%, respectively. Similarly, during ebb tide consisted of 51.7%, 24.2%, and 24.1%, respectively. It suggests that gillnets are not sized selective gear. In contrast, bai...
متن کاملQuantitative and Qualitative Analysis of Chitin and Chitosan from the Shell of the Mud Crab, Scylla Serrata (forskal, 1775)
Chitin and Chitosan are polysaccharides found abundantly in nature. The presence of these polysaccharides is found largely in marine ecosystem next only to the plant source is noteworthy. Especially the production and consumption of crustaceans like crabs and prawns have increased in the recent years, thereby generating a large amount of solid shell waste. In the present study the crab, Scylla ...
