The hydrolysis condition was optimized using Response Surface Methodology (RSM) by applying four factors (time, temperature, pH, Alcalase® concentration), 3-levels Central Composite Design (CCD) with six central points. The chemical and amino acid compositions, structural properties, solubility, emulsifying and foaming properties, water holding and fat binding capacity of EPH were determined. The EPH was separated through ultrafiltration membranes (10 kDa, 5 kDa and 3 kDa). The ferric thiocyanate, thiobarbituric reactive substance, reducing power, ferrous ion chelating activity and 1,2-diphenylpicrylhydrazyl radical scavenging activity of fractionated EPH were also determined. The anticancer activity was determined using MCF-7 cell lines. In order to obtain the optimum yield, degree of hydrolysis (DH) and DPPH activity, the optimum hydrolysis condition suggested was 84.02 min, 50.18°C, pH 7.89 and 2.26% Alcalase® concentration 2017-10-01T00:00:00Z http://umt-ir.umt.edu.my:8080/handle/123456789/14247 Title: Morphological and biochemical characteristics of wild hevea specie Authors: MORPHOLOGICAL AND BIOCHEMICAL CHARACTERISTICS OF WILD Hevea SPECIES Abstract: Hevea brasiliensis or commonly known as rubber tree is the most common rubber species planted nationwide. Wild rubber species such as H. benthamiana, H. camargoana, H. guianensis, H. nitida, H. pauciflora, H. rigidifolia and H. spruceana are not been explored as commercial planting materials. There was an indication that showed the declining in genetic advance of rubber planting materials derived from H. brasiliensis. This was due to narrow genetic base and inbreeding depression. The objectives of this research were to determine the morphological and biochemical characteristics, rootstock-scion compatibility and latex yield in eight different wild Hevea species. The morphological and biochemical characteristics of wild Hevea species were analyzed with various methods including visual observation, light microscopy, Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Gel Permeation Chromatography (GPC) and spectrophotometry. Rootstock-scion compatibility and latex yield were analyzed with bud-grafting method and fresh latex collection. 2016-07-01T00:00:00Z http://umt-ir.umt.edu.my:8080/handle/123456789/14246 Title: Organic fertilizer usage for sweet corn grown on spodosol and ultisol soils Authors: Yahaya Haruna Rawayau Abstract: Poor soils need to be fertilized for optimum crop production in order to achieve the food security campaigns especially in the developing and underdeveloped countries. This study was aimed at finding the potential benefits of organic fertilization for sweet corn grown two marginal soils (Rhu Tapai or Spodosol and Rasau or Ultisol) as well as the optimum rate of the organic manure that gives the best crop performance. A 5x2x2 factorial experiment using Randomly Complete Block Design (RCBD) was conducted in four replicates at the shade house to find the best organic manure between chicken manure, cattle manure, horse manure, rice husk biochar and the control treatment (without amendment) with or without Arbuscular Mycorrhiza Fungi (AMF) inoculation under two different soil types; Rasau series soil and Rhu Tapai series soil using Thai super sweet corn as a test iv crop 2017-12-01T00:00:00Z http://umt-ir.umt.edu.my:8080/handle/123456789/14245 Title: Isolation and identification of lactic acid bacteria from fermented durian flesh and antibacterial activity of related compounds Authors: Fajriah Salleh Abstract: Lactic acid bacteria ( LAB ) are well known for their ability to inhibit the growth of pathogenic bacteria through their antibacterial properties. this study was conducted to isolated and identify LAB from fermented durian flesh in Terengganu, to determine antibacterial activity using well diffusion method and to identify the antibacterial compounds from Cell Free Supernatant (CFS) of selected LAB. 2017-08-01T00:00:00Z
