Biodegradation and bioelectricity generation of melanoidin in palm oil mill effluent (POME) by laccase-producing bacterial consortium integrated with microbial fuel cell

Utilizing melanoidin consuming microalgae for electricity generation and wastewater treatment via photosynthetic microbial fuel cell

“…The melanoidin was prepared according to Thipraksa et al (2022). Briefly, the stock melanoidin (29,160 mgCOD/L) contains 450 mg/L of laboratory--grade glucose, 188 mg/L of laboratory-grade glycine, and 42 mg/L of sodium bicarbonate (NaHCO 3 ).…”

“…The expansion of the oil palm agribusiness has led to the generation of significant quantities of liquid waste known as palm oil mill effluent (POME) (Waidi et al, 2021). It is projected that approximately 2.5 to 3.8 tons of palm oil mill effluent (POME) are generated for every ton of crude palm oil produced through industrial processing (Cheng et al, 2019).…”

Electricity production from palm oil mill effluent (POME) through the integration of a microbial fuel cell and bilirubin oxidase-producing bacteria

“…The facultative anaerobic consortium (S5) consisting of Citrobacter werkmanii, known for its ability to degrade melanoidin, was obtained from the Faculty of Science, Thaksin University (Thipraksa et al, 2022). The consortium was cultivated in nutrient broth (HiMedia, India) under static conditions at room temperature for 48 hours and subsequently stored at 4 ºC until its utilization in the present experiment.…”

Strategic regulation of barrier characteristics of biofilms to enhance the extracellular electrogenic performance in MFCs: an electrochemical dynamic evaluation study

“…34 Various prior researchers have reported the use of mixed microbial consortia as a more practical and sustainable approach for MFC real-time applications. [35][36][37][38] The comprehensive analysis of the phylogenetic diversity of most of the MFC microbial community revealed the dominance of Gram-positive bacteria, including some belonging to the phylum Firmicutes, even though they are considered as weak exoelectrogens. The EET activity of each member of the microbial community must be considered for better understanding of the MFC principle.…”
