DIVERSITY OF NITIDULIDAE BEETLE (COLEOPTERA : NITIDULIDAE)IN BUILT-UP AREAS OF UNIVERSITI TEKNOLOGI MARA, JENGKA CAMPUS,PAHANGDania Ludeen Mahanan, Putri Qurratu'Aini Muhyizul Hafiz, Syed Muhammad Tuan Syed Razman, Muhammad Aleef Fazreeq Adzhari, Dhiya Humairah Supian, & Roziana Bujang1Faculty of Applied Sciences, Universiti Teknologi MARA, Jengka Campus, 26400 Bandar PusatJengka, Pahang *roziana2916@uitm.edu.myABSTRACT This study aimed to determine the diversity, abundance, and distribution of Nitidulidae (Coleoptera) in selected built-up areas of Universiti Teknologi MARA (UiTM) Jengka, Pahang. Sampling was conducted using banana- baited traps placed at seven locations representing different anthropogenic environments within the campus. Collected specimens were preserved and identified in the laboratory using morphological characteristics under a dissecting microscope. A total of seven species of the genus Carpophilus were recorded, namely C. marginellus, C. nepos, C. maculatus, C. mutilatus, Carpophilus sp. 1, C. hemipterus, and C. obsoletus. Among these, C. mutilatus and C. obsoletus were the most dominant species. Beetle abundance varied among sampling days and locations, with higher abundance observed in areas with vegetation cover and greater availability of organic matter.The Shannon–Wiener diversity index showed the highest diversity at Field 1 (H = 1.624), while the lowest diversity was recorded at the Biology Plot Area (H = 0.000), indicating strong variation in species diversity among locations.The findings indicate that built-up environments within the campus are capable of supporting diverse Nitidulidae communities. Future studies are recommended to include longer sampling periods, seasonal comparisons, and additional trapping methods to provide a more comprehensive understanding of sap beetle ecology in urban environments.Keywords: Nitidulidae, Carpophilus, banana-baited traps, built-up areas, UiTM Jengka
TOXICITY OF LEACHATE TO FISH EMBRYOSABSTRACT Leachate generation is an unavoidable consequence of landfill and open dumpsite operations, posing significant environmental concerns due to its potential toxicity. This study aimed to evaluate the toxic effects of landfill leachate on the embryos of Anabas testudineus. Leachate samples were collected on two separate occasions from the Sungai Ikan Landfill, Terengganu. The results demonstrated that exposure to high leachate concentrations (60–100%) resulted in substantial embryo mortality from 37% to 97%. Surviving embryos were predominantly unhatched or exhibited developmental deformities. In contrast, embryos exposed to a 30% leachate concentration showed a high hatching success rate (>94%), with relatively low deformity incidence (<13.33%). The most frequently observed abnormalities included embryo coagulation (3.0–93%) and tail malformations (26–73%), indicating that specific components of the leachate may disrupt critical stages of embryonic development. Additionally, apoptosis analysis using propidium iodide staining and fluorescence microscopy revealed increased embryonic cell death, further confirming the toxic impact of the leachate. Notably, the findings suggest that a 30% dilution of Sungai Ikan landfill leachate may be relatively safe for embryonic development. This concentration could therefore be considered as a preliminary dilution strategy prior to storage in a sanitary containment system.Mohd Yusoff Nurulnadia , Nursyahmi Syahirah Sofia Hasnizam , Nurul Iman Athirah Hamdan 1,2* 1 11Faculty of Science and Marine Environment, Universiti Malaysia Terengganu, 21030 KualaNerus, Terengganu2Ocean Pollution and Ecotoxicology (OPEC) Research Group, Universiti Malaysia Terengganu,21030 Kuala Nerus, Terengganu *nurulnadia@umt.edu.myKeywords: climbing perch; landfill; Sungai Ikan, TerengganuThemes: Applied Biology - Biodiversity and Conservation of Natural Resources
POTENTIAL OF FUNGAL BIOSURFACTANT AND ENZYMES IN POLYETHELENE TEREPHTHALATE (PET) BIODEGRADATION Wan Syaidatul AQMA Qiuhong NIU and Xuyang WEI1*, 2 1,2ABSTRACT Polyethylene terephthalate (PET) is a widely used plastic with an excellent mechanical property, but its resistance to degradation possesses a major environmental threat. Traditional disposal methods such as incineration and landfilling are energy-intensive and environmentally harmful. Therefore, biological degradation, particularly by microorganisms has gained attention as a promising eco-friendly solution. This study aimed to screen and characterised biosurfactant-producing and PET-degrading fungi from plastic- contaminated environments, optimise fermentation parameters for biosurfactant production and evaluate the synergistic effects of biosurfactants on PET degradation. Soil and water samples were collected from a contaminated Malaysian mangrove forests and highly plastic-contaminated rivers in China. A total of 161 fungal isolates were obtained. Surface activity assays were used to assess biosurfactant production; concurrently lipase and esterase assays evaluated enzymatic activity for PET degradation. Trichoderma asperellum PBW1 was identified as the most potent biosurfactant producer (EI24 =69.14 ±2.08%, ST = 48.2 ±2.1 mN/m), while Geotrichum klebahnii ETG-W-1-5 showed the highest PET degradation ability (weight loss rate 7.01 ± 2.14% in 30d), confirmed by high performance liquid chromatography (HPLC), liquid chromatography mass spectrometry (LC-MS), scanning electron microscopy (SEM) and weight loss analysis. Biosurfactants were extracted from PBW1 using acid precipitation and organic solvent extraction methods. Their physical and chemical properties, along with their composition, were analysed using acid bromophenol blue, methylene blue, sulfuric acid-anthrone, ninhydrin assay, thin-layer chromatography (TLC), and LC-MS. The biosurfactant was determined to be an anionic type, characterised by an amino acid-like terminal structure. It contained sugars, lipids and a complex biosurfactant with a lipid core. When applied to PET degradation, the PBW1-derived biosurfactants significantly enhanced degradation efficiency, with degradation product content 1.85 times higher than that in the treatment without biosurfactant addition. These findings highlight the potential of synergistic interactions between fungal biosurfactants and enzymes in improving PET biodegradation. The study offers new microbial resources and biocatalysts for plastic waste management, providing valuable insights into environmentally friendly strategies for PET bioremediation.1Department of Biological Sciences & Biotechnology, Faculty of Science & Technology,Universiti Kebangsaan Malaysia, Bangi, Selangor 43600, Malaysia2College of Life Science, Research Center of Henan Provincial Agricultural Biomass ResourceEngineering and Technology, Nanyang Normal University, Nanyang 473061, PR China *syaidatul@ukm.edu.myKeywords: Polyethylene terephthalate (PET), Fungal biodegradation, Biosurfactants, Plastic waste bioremediation, Mangrove ecosystems
DEVELOPMENT AND CHARACTERIZATION OF FUNCTIONAL DRIED JELLY FROM TEBU GAJAH (Albizia myriophylla): A SUSTAINABLE BIOINDUSTRYAPPROACHLai F. C. , Siti Roshayu H.1 1*1Faculty of Bioengineering and Technology, Universiti Malaysia Kelantan, 17600 Jeli, Kelantan,Malaysia*roshayu.h@umk.edu.myABSTRACT This study aimed to develop and characterize a functional dried jelly made from Albizia myriophylla, a medicinal plant renowned in Malaysia for its traditional therapeutic effects, including antioxidant properties. Despite its potential, its application in modern food innovation remains limited. This study first formulated the jelly using different concentrations of agar powder (1.0%, 1.5%, 2.0%, and 2.5% w/v) and assessed its consistency. Dehydration was then performed under four drying conditions: food dehydrator drying at 40°C, 50°C, and 60°C, and sun drying. The methodology focused on characterizing the physicochemical properties of the samples, including pH, moisture content, colorimetric analysis, and texture analysis (TPA). Furthermore, the functional potential of the dried jelly was evaluated through screening of phytochemical components (flavonoids, saponins, tannins, and steroids/terpenoid) and a DPPH free radical scavenging assay. Visual consistency assessment results showed that increasing the agar concentration significantly improved the firmness of the jelly matrix. Drying analysis showed that higher temperatures can remove moisture faster but often resulted in more severe degradation of bioactive compounds compared to gentler drying methods. Characterization results showed that the dried jellies retained measurable phytochemicals and antioxidant activity, with sun-dried and low-temperature (40°C) dried samples retaining more bioactive components. This study proved that A. myriophylla can be successfully integrated into a stable plant-based gelling matrix, supporting the development of sustainable bio-industries and providing a high-value functional food for health-conscious consumers.Keywords: Albizia myriophylla, functional dried jelly, agar, antioxidant activity, DPPH assay.Themes: Food Science and Technology, Biotechnology, Biodiversity and Conservation of Natural Resources.
EMERGING POTENTIAL OF SUSTAINABLE BIOPLASTICS FOR FUTURE BIOMATERIALSVigneswari S1*1Institute of Climate Adaptation and Marine Biotechnology, Universiti Malaysia Terengganu*vicky@umt.edu.myABSTRACT Sustainable bioplastics have emerged as a critical class of next-generation biomaterials, offering eco- friendly alternatives to conventional petroleum-based plastics while addressing biomedical needs. Among these, polyhydroxyalkanoates (PHAs) stand out as bacterial biopolymers produced under nutrient-limited conditions. PHAs are highly valued for their biocompatibility, biodegradability, and inert in-vivo degradation products, making them suitable for applications such as drug delivery systems, implants, scaffolds, tissue engineering, and artificial organ constructs. In particular, poly(3- hydroxybutyrate-co-4- hydroxybutyrate) [P(3HB-co-4HB)] has gained attention due to its non-cytotoxicity and favorable biological properties. Surface modification strategies, including nanofabrication and chemical modification, are employed to enhance cell–scaffold interactions and proliferation. Complementing PHAs, other natural polymers derived from marine organisms are increasingly explored for biomedical innovation. Collagen, extracted from fish and other marine sources, provides structural integrity and excellent biocompatibility, making it indispensable in tissue engineering and wound healing. Chitosan, obtained from crustacean shells, contributes biodegradability, antimicrobial activity, and cell adhesion properties, further broadening the scope of sustainable biomaterials. Together, PHAs, collagen, and chitosan exemplify the versatility and promise of sustainable bioplastics. Their synergistic properties pave the way for advanced biomedical applications, supporting the vision of eco-friendly, high-performance biomaterials for regenerative medicine and drug delivery.Keywords: bacterial plastics, biomedical applications, chitosan, circular bioeconomy, polyhydroxyalkanoates (PHAs)Themes: Applied Biology (Biotechnology, Microbiology
