Selected fatty acid profile of Pomacae canaliculata : Optimization of solid-liquid phase extraction
(Universiti Malaysia Perlis (UniMAP), 2012-06)
Apple snails were the species that survive and spread widely in the freshwater especially in paddy field. It became a serious rice pest to the farmers due to feeding of young rice seedling. However, apple snails were ...
Production of bioprotein from Empty Fruit Bunch using Aspergillus niger for fish feed application
(Universiti Malaysia Perlis (UniMAP), 2012-06)
Bioproteins is proteins derived from microorganisms by fermentation of agricultural waste products, with low cost carbon sources and high energy sources. This study aims to improve the production of bioprotein for fulfilling ...
Optimization for the photocatalytic degradation of methylene blue using Sol-gel Derived TiO2 photocatalyst supported on montmorillonite
(Universiti Malaysia Perlis (UniMAP), 2012-06)
Photocatalytic is a method that can be used to replace conventional wastewater treatment to treat dyes in industry. Photocatalytic degradation of methylene blue (MB) required titanium dioxide (TiO2) photocatalyst under UV ...
Physical parameter optimization of feather protein hydrolysate production by Saccharomyces cerevisiae using submerged fermentation
(Universiti Malaysia Perlis (UniMAP), 2012-06)
Commonly, feathers are known as a solid waste in the poultry industries. It contains about 91% of keratin which a tough insoluble protein substance and hence, make the feathers itself as the one of the alternative protein ...
Study on extraction methods for protease production from Sterblus asper
(Universiti Malaysia Perlis (UniMAP), 2012-06)
Streblus asper leaves were collected and used as a plant source for extracting protease enzymes. The enzyme was extracted by three methods and the activity of each extract was determined. Streblus asper leaves were extracted ...
Optimization of media composition of lipase production from oil palm press fiber (OPPF) by solid state fermentation
(Universiti Malaysia Perlis (UniMAP), 2012-06)
Lipase is an enzyme which capable to be catalyst in the hydrolysis and the synthesis of esters formed from glycerol and long-chain fatty acids. Oil palm pressed fiber (OPPF) is an agricultural waste know as mesocarp fiber ...
Removal of fluoride from aqueous solution using algal bio-adsorbent
