Article
Full-text available
Bacterial cellulose produced by acetic acid bacteria has shown wide potential applications in various fields including the food industry, paper manufacturing, cosmetics, and biomedicine. This study was conducted to identify the potential of oil palm empty fruit bunch (OPEFB) as an alternative carbon source for the production of bacterial cellulose...

Lactic acid has become one of the most important chemical substances used in various sectors. Its global market demand has significantly increased in recent years, with a CAGR of 18.7% from 2019 to 2025. Fermentation has been considered the preferred method for producing high-purity lactic acid in the industry over chemical synthesis. However, the...

A total of 24 strains of Vibrio alginolyticus were isolated from cockles (Anadara granosa) and identified for VibA and gyrB genes. All V. alginolyticus isolates were then tested against nine different antibiotics. In this study, the highest percentage of antibiotic resistance was obtained against penicillin (37.50%), followed by ampicillin, vancomy...

Mature coconut husk (MCH) and young coconut husk (YCH) are abundantly generated as a by-product from coconut-based industry, which eventually lead to environmental pollution. However, the lignocellulose content in both types of coconut husk has the potential to be exploited as feedstock by way of biochemical processes through the concept of biorefi...
Article
Penghasilan asid laktik D semakin mendapat perhatian kerana sifat polimernya, poli asid laktik D, yang termostabil. Kajian ini dijalankan untuk menghasilkan asid laktik D daripada sisa pertanian yang tidak bernilai tinggi seperti sabut kelapa tua (SKT) dan sabut kelapa muda (SKM) melalui teknologi fermentasi. Peringkat pertama kajian, SKTdan SKM di...
Article
Costus plant is considered as a medicinal plant especially in therapeutic intervention. The current study reports the composition, phytochemical and antioxidant properties of red button ginger (Costus woodsonii) using sequential extraction. Solvents of different polarities (hexane, ethyl acetate, methanol and water) were used to sequentially extrac...
Article
The complete utilisation of Dried Distillers Grains with Solubles (DDGS) requires effective pretreatment strategies aiming to increase the enzymatic digestibility of cellulose and improve its conversion to fermentable sugars. To this end, the effect of different NaOH concentrations (0–5%, w/v) and temperature (30–121 °C) on the fractionation of DDG...
Article
A multi-step process was developed for microbial d-lactic acid purification, followed by poly-d-lactic acid (PDLA) synthesis via azeotropic polycondensation process. Several anion exchange resins were screened for their binding capacity using model lactic acid solutions. Amberlite® IRA67 (weak base anion exchange resin) showed the highest lactic ac...
Article
D‐Lactic acid production is gaining increasing attention due to the thermostable properties of its polymer, poly‐D‐lactic acid (PDLA). In this study, Lactobacillus coryniformis subsp. torquens, was evaluated for its ability to produce D‐lactic acid using Dried Distillers Grains with Solubles (DDGS) hydrolysate as the substrate. DDGS was first subje...

Article
Dried Distillers Grains with Soluble (DDGS) is a by-product of bioethanol and distillery industries that is currently marketed as animal feed. DDGS are characterised by high protein and fibre (lignocellulose) content, which shows potential to be utilised as alternative feedstock for microbial fermentations. Lignocellulose hydrolysate is commonly co...

Article
Kundur [Benincasa hispida (Thunb.) Cogn.], a member of the family Cucurbitaceae, is one of the famous crops that are grown primarily for its fruits and usually recognized with its nutritional and medicinal properties especially in Asian countries. Kundur fruit has been valued as a nutritious vegetable as it provides a good source for natural sugars...
Article
Full-text available
The seeds from Kundur [Benincasa hispida (Thunb.) Cogn.], a fruit vegetable plant with high functional properties (especially in medicinal treatment), were analysed for nutritive parameters (dietary fiber, crude protein, crude fat, crude fiber, ash, and energy) and oil fatty acids composition. Proximate analysis of the seeds revealed the total d...
Article
The objective of this study was to determine the level of preservatives and microbiological loads in various brands of commercially available chili bo (paste). Fifteen different brands of chili bo obtained from the local market and hypermarkets were analyzed for pH, moisture and benzoic acid content, microbiological loads (aerobic, anaerobic, aerob...
