ABSTRACT

Bacterial cellulose-silver nanoparticles (BC-AgNPs) composite was prepared for a bacterial wound dressing. The oil palm frond (OPF) juice was utilised as a low-cost raw material for BC production. The AgNPs were incorporated in the BC composite by thermal reduction of 1 mM silver nitrate for their antibacterial agent. The BC-AgNPs composite had dense nanofibrils with an average diameter of 61.5 ± 1.0 nm as shown in the field emission scanning electron microscope (FESEM) images. The composite had a crystallinity index of 86.5% and the nanoparticles had a face-centred cubic geometry with a crystal size of 26.5 nm as determined by X-ray diffraction analysis (XRD). The Ag content was 1.463 mg/100 cm2 in the composite analysed by atomic absorption spectrophotometry (AAS). 10.4% of the total Ag content was released from AgNPs in 72 hr as measured by inductively coupled plasma mass spectrometry (ICP-MS). The composite also demonstrated excellent antibacterial action against Staphylococcus aureus, giving a 29 ± 0.8 mm inhibition zone by the disk diffusion assay. Pure BC composite exhibited no cytotoxicity effect on the HSF1184 fibroblast cells and 10%-40% BC-AgNPs composite extracts were compatible with the cell growth. The study suggests the BCAgNPs composite is a good material for antibacterial wound dressing.

PATENT LANDSCAPE REVIEW ON MODERN OIL PALM CLIMATIC ADAPTATION STRATEGIES: GAPS AND OPPORTUNITIES

Climate change is evolving at both a speed and magnitude that necessitates oil palm adaptation through innovation. This study both tracks and synthesises climate change adaptation patents applicable to oil palm cultivation. Oil palm patent applications filed between 1960 and 2022 were analysed through a network analysis, and compared to patents applied for soybean, rapeseed, […]

DIETS AND HEALTH BENEFITS OF GUT MICROBIOTA-FERMENTED SHORT-CHAIN FATTY ACIDS: A PERSPECTIVE OF THE MALAYSIAN DIET CONTAINING PALM OIL

A healthy diet provides a favourable environment that allows the essential bacteria to grow and ferment beneficial metabolites, short-chain fatty acids (SCFA) through various metabolic pathways. SCFA, including linear- and branched-SCFA (BSCFA) are important in regulating energy haemostasis, inflammation, and appetite. A plant-based diet is associated with increased SCFA levels and SCFA-producing bacteria that regulate […]
