“…It belongs to multi-copper polyphenol oxidase, containing four copper ions in two active sites [1,2]. It is reported to be rather unspecific and be able to catalyze a broad range of substrates, including phenols, polyphenols, chlorinated phenols, polyamines, dyes, aromatic substrates and some inorganic com- [10], organic and inorganic membranes, natural mineral materials, magnetic microsphere or organic gels [11], and various methods, such as adsorption [12], crosslinking attachment [13], entrapment or encapsulation [14] have been used to immobilize laccase.…”

“…Laccase (Lac) activity was determined at 420 nm using ABTS (2,2'-Azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) as a substrate. The assay mixture contained 1 mM ABTS in 100 mM sodium acetate buffer (pH 3.6) mixed with 10 μL aliquots of crude enzyme in a total volume of 200 μL [1]. Manganese peroxidase (MnP) activity was estimated by spectrophotometry at 415 nm using ABTS as a substrate.…”

“…All wooddecaying fungi -including the white-rot fungi Trametes versicolor, Pleurotus ostreatus, Xylaria sp., and the termite-associated fungus Termitomyces sp. -show high potential of lignin-modifying enzyme production [1,2,5,16]. Symbiotic yeasts play an essential role through plant material fermentation in the hindgut of subterranean termites.…”

The global situation in the decrease of fossil fuels and other non-renewable energy sources is now of signifi cant concern. Interest in renewable energy is increasing from this situation. The oil palm (Elaeis guineen L.) is known as a sustainable energy source for biodiesel production. It is more versatile than other oil crops and provides a higher yield for less energy input [9]. Highly colored palm oil mill effl uent (POME) generates approximately 60% of global crude palm oil [10]. Today the oil palm is an important economic crop in southern Thailand, and in 2016 oil palm plantations covered an area of 720,000 ha. A recent report by the National Science and Technology Development Agency (NSTDA) indicated that Thai agriculturists produced 9 million tons per year of fresh fruit bunches (FFB), with 0.19 tons of POME released from every ton of FFB. Consequently, around 1.026 million tons of darkcolored POME was produced annually. Raw POME is a highly polluting wastewater containing 95-96% colloidal suspensions, 4-5% total solids, and 0.6-0.7% palm oil. The oxidation of phenolic compounds such as lignin and anaerobically degraded products result in the dark Pol. J. Environ. Stud. Vol. 27, No. 1 (2018), 39-44 AbstractLignin-modifying enzymes have long been used in palm oil mill effl uent (POME) treatment to remove the dark brown colour resulting from phenolic contamination. This study investigated a cost-effective industrial application method for optimizing phenol removal from POME using the termite-associated yeast Galactomyces reessii obtained from the subterranean termite under laboratory conditions. The yeast was cultured in POME, and the activity of the ligninolytic enzymes (laccase and manganese peroxidase) was monitored by spectrophotometry. Optimal conditions were achieved using a Box-Behnken experimental design. Results demonstrated that G. reessii reduced the phenolic compounds in POME by 88.69% with growth in 100% (v/v) POME using 30% (w/v) consortia and 5% (w/v) calcium carbonate (CaCO 3 ) at room temperature 30 1C for seven days. G. reessii showed high performance for phenolic removal and decolourization of POME and other industrial wastewaters.
