Optimization of epoxidation blending oil of jatropha and soybean oil for biolubricant application
Noor Hajarul Ashikin, Shamsuddin (Universiti Malaysia Perlis (UniMAP)School of Bioprocess Engineering, 2012-06)The study was carried out to optimize of epoxidation blending of jatropha seed oil with soybean oil as biolubricant precursor. The jatropha was extracted by using Soxhlet method with high yield of crude extract at extraction ... -
Optimization of Protease Enzyme from Kesinai (Streblus asper) for Milk Coagulation
Seow, Yen Yi (Universiti Malaysia Perlis (UniMAP)School of Bioprocess Engineering, 2013-06)Streblus asper (Kesinai) leaves contain proteases that can be used to coagulate milk. The enzyme was extracted by using phosphate buffer at pH 7.2 and the extracted enzyme activity was tested for protease assay. Response ... -
Purification and kinetic study of protease enzyme from kesinai (streblus asper) leave
Nurul Izzati Izni, Mat Yusoff (Universiti Malaysia Perlis (UniMAP)School of Bioprocess Engineering, 2013-06)A study was carried out to purify protease enzyme from kesinai leaves extract. The protease enzyme was extracted by using phosphate buffer at pH 7.5. The crude enzyme extract was further with the purification technique by ... -
Screening and Kinetic study of in situ Epoxidation Methyl Ester Jatropha Curcas Oil as Biolubricant Precursor
Lim, Gim Pao (Universiti Malaysia Perlis (UniMAP)School of Bioprocess Engineering, 2012-06)The methyl ester of Jatropha curcas seed oil (JCO) with iodine value of 98.136 I2/100g, and the dominant fatty acid of methyl ester Jatropha curcas seed oil are oleic acid 46 % and linoleic acid 32 % was determined by gas ... -
Screening of blending Jatropha Curcass oil with waste cooking oil as bio-Iubricant precursor
Siti Nur Amalieya Syaza, Mohd Zuki (Universiti Malaysia Perlis (UniMAP)School of Bioprocess Engineering, 2013-06)The vegetable oil such as Jatropha CUTCas oil with high oleic acid (monounsaturated fatty acid) content has been demanded as an alternative for mineral oil-based lubricant due to price fluctuation of petroleum feed stock ... -
Studies of potential plant parts of Kesinai (Streblus asper) for protease production
Kua, Lay Chim (Universiti Malaysia Perlis (UniMAP)School of Bioprocess Engineering, 2012-06)A study was carried out to study the potential plant parts of Kesinai (Streblus asper) for protease production. The potential parts of Streblus asper such as leaves, stem barks, and twigs were collected and used as a source ... -
Study on extraction methods for protease production from Sterblus asper
Wan Ahmad Izzuddin, Wan Mahmood (Universiti Malaysia Perlis (UniMAP)School of Bioprocess Engineering, 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 ...
