Summary: Palm oil mill effluent (POME) is the wastewater produced during palm oil sterilization process, containing harmful nutrients and phosphorous. Effective pre-treatment of POME is essential due to its high BOD and COD levels. Microalgae, such as C. pyrenoidosa, show potential in treating POME by achieving nutrient reduction and lipid production. Experimental studies on microalgae characteristics and performance are being conducted for feasibility assessment, with the aim of biofuel production.

Summary: Haematococcus pluvialis exhibited better adaptability to higher concentrations of palm oil mill effluent (POME), leading to higher astaxanthin yield and reduced freshwater consumption for astaxanthin production. However, only moderate performance in phycoremediation was achieved. The study showed that POME from Sri Lankan palm oil mills has the potential to be utilized for large-scale production of microalgal astaxanthin.

Summary: Water scarcity is a global challenge and improving water circulation efficiency is important. In the palm oil industry, the extraction process produces a large amount of wastewater called POME, which requires better treatment methods. Membrane technology and water reclamation techniques, such as evaporation, show promise in achieving high-quality water from POME. Additionally, recovering by-products like biofertilizers and biofuels is necessary to make the treatment economically feasible and shift towards a circular economy approach.

Summary: The use of cyanobacteria for PHB accumulation for bioplastic production offers cost-saving opportunities. Synechocystis sp. was found to produce the highest amount of PHB compared to other cyanobacteria strains. Optimizing the interaction of glycerol and UV-C irradiation, or glycerol and iron addition further increased PHB production in Synechocystis sp.. The highest production was achieved at 670 mg L-1 glycerol, 70 min UV-C irradiation time, and 20 mg L-1 iron, with PHB dominated by butyric esters and thermal stability at 284 degrees C.

Summary: This study isolated fungal strains from river water to investigate their potential as coagulants. The myco-coagulant produced by one of the fungal strains, Lentinus squarrosulus strain 7-4-2 RWF-5, was characterized and found to have good flocculation performance. The flocculation mechanism of the myco-coagulant was a combination of polymer bridging and charge neutralization.

Summary: In this study, a fungal strain was used to produce a myco-coagulant through solid-state bioconversion for the purpose of reducing water turbidity. Lignocellulolytic substrates such as coco peat, sawdust, palm kernel cake, and rice bran were utilized as carbon and nitrogen sources. The effects of these substrates and various parameters on myco-coagulant production were investigated. Coco peat was found to be the most suitable substrate, achieving a turbidity reduction of 84.6% from the kaolin suspension. Statistical analysis revealed that glucose, malt extract, and pH had significant effects on flocculation activity. Further optimization was conducted to evaluate the influence of these factors on flocculation activity.

Summary: This study demonstrates the potential of using biofilm for enhancing biogas production in the hydrolysis step of food waste. Immobilized biofilm-producing microorganisms on a granular activated carbon surface were optimized using statistical methods. The optimal conditions were found to be 48 h of incubation, 8 g of GAC, and 1 mL of inoculum. The degradation of organic compounds was increased by using different amounts of biofilm in hydrolysis flasks, with the highest degradation achieved on day 3 and using 328 mg of biofilm.

Summary: The production of biogas from food waste is an effective method for both reducing food waste and increasing renewable energy production. However, the current use of food waste as a feedstock for biogas production is hindered by an ineffective hydrolysis process, which impacts the volume of biogas produced. Improving the biodegradation of organic compounds during the hydrolysis process is crucial for enhancing biogas generation.
