Summary: Biomass and lipid production of Thalassiosira pseudonana, a marine centric diatom, were studied using palm oil mill effluent (POME) as a nutrient source. The optimal medium consisted of 20% POME, 80 μM Na2SiO3, and 35 g NaCl L-1, with a pH of approximately 7.7. Under specific light conditions, high biomass and lipid content were achieved in Thalassiosira pseudonana cultures.

Summary: The large quantities of palm oil mill effluent (POME) create a significant pollution problem. In this study, we demonstrate that the introduction of plasma and MHz-order sound waves can greatly reduce the treatment time and improve the removal of pollutants in POME. Plasma exposure enhances oxygen dissolution and organic compound dissolution, while sound waves promote convective mass transfer and bacterial decomposition. Combining plasma pretreatment and sound wave irradiation can lead to a fivefold reduction in the total treatment duration, making this hybrid technology promising for industrial-scale treatment systems.

Summary: The study investigated the biohydrogen and biomethane potential of palm oil mill effluent (POME) in a two-stage anaerobic digestion system under thermophilic and mesophilic conditions. The results showed that the best production potentials were obtained from POME with an initial 0.5 g-COD loading, and the energy yield achieved from two-stage AD was significantly higher than single-stage AD. Continuous production of hydrogen and methane revealed that the highest yields were generated at specific hydraulic retention times, with an overall COD removal of approximately 66.27%.

Summary: In this study, lignocellulolytic enzymes were efficiently produced from industrial crop wastes, specifically palm empty fruit bunches (EFB), using different fermentation modes and co-cultivation of filamentous fungi. Aspergillus tubingensis TSIP9 showed the highest cellulase and xylanase activities, while Trichoderma reesei QM9414 exhibited the highest beta-glucosidase activity. Co-cultivation significantly improved overall enzyme production, leading to enhanced activities of cellulase, xylanase, and beta-glucosidase after optimization and scaling up in a bioreactor with a helical impeller. These enzymes are highly active and stable under specific pH and temperature conditions, making them promising for low-cost production and biorefinery applications.
