Summary: The treatment of palm oil mill effluent (POME) was studied using a novel nanocomposite powder consisting of titanium dioxide (TiO2) and montmorillonite clay (MMT) for adsorption. The addition of the nanocomposite resulted in reduced levels of heavy metals, turbidity, pH, chemical oxygen demand (COD), and total suspended solids (TSS) in POME. The optimal composition of the nanocomposite was determined to be 1wt% KOH-AC, 0.628wt% TiO2, and 2wt% MMT clay.

Summary: This study investigates the use of diluted palm oil mill effluent (POME) for Sporosarcina pasteurii survivability and microbial-induced carbonate precipitation (MICP) application. The results show that diluted POME at different concentrations achieved varying biomass production and urease activities, and the precipitation of calcium carbonate increased with the molarity of cementation chemicals. Scanning electron microscopy and energy-dispersive spectroscopy confirmed the presence of diverse crystal-like forms and identified the elements involved in the crystal structures. Instrumental studies further evaluated the chemical functional groups and thermal behaviors of the biocemented samples, highlighting the potential of POME in reducing the costs of MICP implementation.

Summary: This study aimed to evaluate the mass transfer kinetics of chemical oxygen demand (COD) removed from palm oil mill effluent (POME) using stirred cylinder batch reactor (SCBR) under anaerobic conditions. The COD removal efficiency of SCBR reached 77.6% of its maximum efficiency at a hydraulic retention time of 9 days. The resistance of mass transfer for COD removal from POME by SCBR process depends on external mass transfer, and the variation of [kLa]d value is similar to that of [kLa]g value but much higher than that of [kLa]f value.

Summary: Biological-based treatments, including the existing open-ponding system, are more likely to be employed as the major treating approach for treating POME due to their better performance index for concentrated POME, lower treatment cost, and technicality needed. High biogas generability of biological-based treatments further makes them irreplaceably benchmarked for POME treatment in Malaysia.

Summary: The alarming rise of food waste all over the world due to population and economic growth must be tackled with better waste management and treatment methods. The current practice of landfilling has been scientifically proven to adversely impact environmental and societal health. Hydrothermal carbonization (HTC) technology offers a solution by converting high-moisture-content material into bio-coal with a heating value similar to normal coal. This study explores the feasibility of HTC technology and bio-coal production in Malaysia, finding that there is sufficient food waste in the country to sustain the raw material for the bio-coal project. However, high production costs and incompatibility with existing industrial processes are the main hurdles to adoption.

Summary: The presence of impurities in the feedstock is a major cause of premature catalyst deactivation in the catalytic hydrogenation of fatty acids. The quality of feedstock, particularly in the case of crude palm oil (CPO), can be estimated by the deterioration of bleaching index (DOBI). Experimental results showed that catalyst deactivation was linked to DOBI value, with decreasing DOBI leading to faster catalyst deactivation.

Summary: This study compares the performance of a nanofiber device and a resin column for antibody capture. The nanofiber device has a larger housing volume and lower binding capacity, but comparable eluate purity to the resin column. It shows high stability, can be used for multiple cycles, and maintains consistent eluate quality when scaled up. The use of a single nanofiber device can significantly reduce costs compared to a resin column, especially when the number of batches is limited.

Summary: Fed-batch cell culture processes are commonly used in biomanufacturing due to their simplicity and applicability in cGMP environments. However, the challenge lies in the changing physiochemical conditions within the bioreactor as the cell density changes. Traditional response surface models (RSMs) are commonly used for optimization but are limited by their use of time-invariant factors. Dynamic RSM (DRSM) models can predict the time-dependent impact of process inputs, allowing for optimization of process operations that change over time.

Summary: In this study, heterologous expression and homologous overexpression of ABC transporter proteins AatA and MdlB were found to improve butyric acid production in C. tyrobutyricum. The overexpression of these proteins upregulated the expression levels of key enzymes in the acetate synthesis pathway and promoted the synthesis and secretion of acetic acid. Additionally, the increase in ATPase activity facilitated sugar utilization, induced extracellular secretion of acetate, and shortened fermentation periods.
