Fatty Acid Liposomes In Cosmetic Cream / Chia Si Wai, Si Wai Chia

Student Works (2010-2019)

Liposomes have been used widely as carriers for active ingredients in cosmetic because of their ability to encapsulate both hydrophilic and hydrophobic compounds. In this work, fatty acid liposomes were prepared and introduced into olive oil-in-water emulsions stabilized by C14–C18 sucrose ester mixtures at pH 8.5. Light microscopy images of the emulsions showed evidence of the coexistence of oleic acid liposomes and the emulsion droplets. As alkyl chain length of sucrose ester increased, the average droplet size decreased, while the zeta potential became more negative. Further decrease of droplet size was observed when borate buffer was added to the aqueous …

Fish And Trophic Connectivity Across Coral Reef And Mangrove Habitats Of North Eastern Langkawi Island, Peninsular Malaysia / Lau Chai Ming, Chai Ming Lau

Student Works (2010-2019)

The presence of disparate biotopes of coral reefs and mangroves in one general area is unique. These biotopes may form ecologically connected ecosystems when occurring in close proximity such as in tropical Langkawi Island, Malaysia. Connected marine biotopes can provide various ecological services to fish community such as nursery, feeding habitats and shelter. As such, this study aims to test two hypotheses regarding Langkawi’s coral reefs and mangroves 1) the biotopes are ecologically connected via habitat utilization by the fish fauna and 2) the biotopes are ecologically connected via trophic energy pathways.

Student Works (2010-2019)

The present study investigated the effects of green, white and black tea (Camellia sinensis; 2% w/v) on the fermentation of milk and antioxidant potential of yogurt. Each tea (water extract) was added into milk-starter culture mixture and incubation was carried out at 42°C until pH was reduced to 4.5. The yogurts were then refrigerated (4°C) for up to 21 days and samples were analysed for antioxidant potential (diphenyl picrylhydrazyl (DPPH) radical scavenging, ferric reducing antioxidant power (FRAP) and ferrous ion chelating (FIC) assays), pH, titratable acid and viable yogurt bacteria counts. Tea yogurts had higher antioxidant potentials (p < 0.05) than plain yogurt with green tea yogurt (GTY) having the highest FRAP (2.49 - 2.98 mmol Fe2+ E/L) and black tea yogurt (BTY) having the highest FIC (87.50 - 89.87 %) activity throughout the storage period. Both GTY (90.07 - 96.74%) and white tea yogurt (WTY; 89.83 - 96.39%) showed the highest DPPH radical scavenging activity throughout the storage period. The presence of green and black tea water extracts prolonged the milk fermentation time (>270 minutes …

We studied temporal variation of picocyanobacteria and their production (μ) and loss (g) rates for over two years of period at Port Klang (PK) estuarine waters [03º00.1'N, 101º23.4'E] and Port Dickson (PD) coastal waters [02º29.5'N, 101º50.3'E] along the Straits of Malacca. PK waters showed higher level of eutrophication, lower euphotic depth and higher TSS level as compared to PD. Heterotrophic bacterial abundance at PK (2.78 ± 1.58 × 106 cell ml–1) was generally higher than PD (1.39 ± 0.49 × 106 cell ml–1) (Student’s t-test: t = – 5.30, df = 47, p < 0.001). In contrast, picocyanobacterial abundance at PD (1.33 ± 0.47 × 105 cell ml–1) was always higher than at PK (0.28 ± 0.17 × 105 cell ml–1) (Student’s t-test: t = 10.44, df = 30, p < 0.001). μ and g of picocyanobacteria were tightly coupled with each other (R2 = 0.47, df = 459, p < 0.001) and similar at both sites (p > 0.05). μ ranged from – 0.03 to …

Coral reefs that occur in Malaysia are of global significance, and an important resource for the sustainable development of the country. One key step taken to conserve the coral reef resources in Malaysia, was the establishment of Fisheries Prohibited Areas (FPAs). Unfortunately, coral reef management measures are virtually non-existent at these areas, exposing the reefs to many pressures driven by the rapid development of the adjacent coastal areas. The limited understanding of the true economic value of coral reef ecosystems, is the main reason that sufficient resources are not appropriated and to manage and conserve this fragile yet important resource. …
