“…Various methods and technologies such as aerobic and anaerobic biological treatment, adsorption, solvent extraction, chemical-biological sedimentation, coagulation-flocculation, microalgae treatment, membrane technology, etc. have been adopted in mitigating the polluting effects of POME in aquatic life [2,[6][7][8][9]. Treatment of POME using advanced oxidation processes (AOP) such as the Fenton process and photocatalysis has gained significant attention and is still developing [10].…”

In recent years, the green chemistry based-approach for the synthesis of nanoparticles has shown tremendous promise as an alternative to the costly and environmentally unfriendly chemically synthesized nanoparticles. In this study, copper oxide nanoparticles (CuO NPs) were synthesized through a green approach using the water extract of papaya (Carica papaya L.) peel biowaste as reducing as well as stabilizing agents, and copper (II) nitrate trihydrate salt as a precursor. The structural properties, crystallinity, purity, morphology, and the chemical composition of as-synthesized CuO NPs were analyzed using different analytical methods. The analytical results revealed that the synthesized CuO was observed as spherical-like in particles with measured sizes ranging from 85–140 nm and has monoclinic crystalline phase with good purity. The Fourier transform infrared (FTIR) spectroscopic results confirmed the formation of the Cu-O bond through the involvement of the potential functional groups of biomolecules in papaya peel extract. Regarding photocatalytic activity, the green-synthesized CuO NPs were employed as a photocatalyst for the degradation of palm oil mill effluent (POME) beneath the ultraviolet (UV) light and results showed 66% degradation of the POME was achieved after 3 h exposure to UV irradiation. The phytotoxicity experiment using mung bean (Vigna radiata L.) seed also showed a reduction of toxicity after photodegradation.

Polyhydroxyalkanoate or PHA is produced through microbial fermentation of sugar and lipid where in nature it is stored as energy and carbon source for microorganisms. Most of the carbon feedstock used for PHA production are derived from biomass as they remain the cheapest carbon source to date. In this study, nipa palm sap was proposed as an alternative carbon feedstock since it is underutilized and widely distributed along river estuaries in Malaysia. This nipa sap contains high sugar content and essential nutrients which are required for PHA production. The aim of this work was to explore potential of nipa sap as a carbon source and to investigate effect of added and non-added nutrient nipa media on PHA production during batch fermentation using Cupriavidus necator DSM545. Extraction of PHA using chloroform showed that 2 g/L of PHA was recovered when nipa added with nutrient was used while nipa only media produced 2.16 g/L of PHA. All the samples showed presence of PHA carbonyl band (C=O) from extracted PHA granules by using FTIR while peak obtained using UV Spectrophotometer confirmed the presence of PHA. These findings proved that nipa palm sap as a novel and alternative carbon source for PHA production.
