Optimization of basic red 46 using chemically modified banana stalk
(Universiti Malaysia Perlis (UniMAP), 2013-05)
This research was conducted to study the feasibilty of using banana stalk as
biosorbent for the removal of Basic Red 46 (BR 46) dye. The chemical
pretreatments were applied to the biosorbent by using hydrochloric acid ...
Extraction optimization of phenolic compond from Zingiber Aromaticum Rhizome using pressurized hot water extraction (PHWE)
(Universiti Malaysia Perlis (UniMAP), 2013-06)
Pressurized hot water extraction (PHWE) method was implemented in order to reduce
the usage of organic solvent in extracting phenolic compound from the rhizome of
Zingiber aromaticum. At first, the screening studies using ...
Screening of media composition for bioprotein production from palm kernel cake by Aspergillus niger for fish feed
(Universiti Malaysia Perlis (UniMAP), 2013-06)
The world’s population are increasing and the demands for natural resources of food
especially protein source such as fish are limited. Only a rational and sustainable effort will continue to produce enough and nutritive ...
Computational design, synthesis, and evaluation of caffeic acid imprinted molecular imprint polymer (MIP)
(Universiti Malaysia Perlis (UniMAP), 2013-06)
Caffeic acid (CA) is a naturally occurring organic compound found in various plants
such as pear, apple, and basil. It also has been identified as one of the active antioxidant
essential in preventing diseases such as ...
Studies on the growth kinetics of lactic acid bacteria under controlled pH cultivation environment using alginate capsules
(Universiti Malaysia Perlis (UniMAP), 2013-06)
End-product inhibition in LAB fermentation has initiates the development of various approaches to minimize the inhibition effect on LAB growth. The inhibition effect can be minimized by controlling the pH in LAB fermentation. ...
Studies on production of chitosan-alginate capsules through extrusion dripping method
(Universiti Malaysia Perlis (UniMAP), 2013-06)
Production of capsules through extrusion dripping method is a simple and low cost
method. Chitosan and alginate are common biopolymers used for in the formation of
capsules in wide range of industries. However, there is ...
Transesterification and purification of biodiesel from waste cooking oil
(Universiti Malaysia Perlis (UniMAP), 2013-06)
In this study, the level of free fatty acids in used oil are low at 0.73 %, hence, single
stage transesterification was sufficient. Two process variables that been investigated
were the molar ratio of methanol-to oil and ...
Equilibrium and kinetic modelling of dye adsorption by eggshell
(Universiti Malaysia Perlis (UniMAP), 2013-06)
The objective of this study was to investigate the removal of Basic Red 46 (BR 46)
from synthetic wastewater by the adsorption onto eggshell. This experiment was
carried out to investigate the effectiveness of eggshell ...
Production of glucose from banana trunk: optimization studies
(Universiti Malaysia Perlis (UniMAP), 2013-06)
Banana trunk (BT) is one example of non-wood fibers and usually discarded as an
agricultural waste from banana plantation in Malaysia. It consists of cellulose (53.45
%), hemicelluloses (28.56 %) and lignin (15.42 %). ...
Immobilization of glucose oxidase enzyme onto organic-inorganic sol-gels matrix on carbon paste electrode biosensor
(Universiti Malaysia Perlis (UniMAP), 2013-06)
A hybrid sol-gel carbon nanotubes composite has been developed and used for surface
covalent bonding of enzyme for biosensing application. The biosensor was developed
by covalent immobilization of glucose oxidase enzyme ...
