“…F022 may take longer as proved in a previous study where the secretion of laccase, LiP, and dioxygenase by Armillaria sp. F022 were highest at day 30 of incubation . This is due to the dependency of enzymes on H 2 O 2 as the cofactor.…”

Armillaria sp. F022, a basidiomycete fungus isolated from a recreational forest in Johor, Malaysia, was tested for its biodegradation ability of the azo dye Acid Red 27 (AR27). Varying carbon and nitrogen sources, agitation, and inoculum concentrations on AR27 dye degradation by Armillaria sp. F022 in liquid medium were investigated to find out their effects on dye degradation. Glucose and ammonium chloride were the best nutrients for the growth of Armillaria sp. F022. The addition of 15% inoculum concentration of Armillaria sp. F022 increased the AR27 dye degradation up to 97.17% within 72 h of incubation. Phytotoxicity tests were performed employing seed germination of Sorghum vulgare and Triticum aestivum by monitoring their elongation of the plumules and radicles to evaluate the toxicity of the degradation products. The metabolites formed during biodegradation were 1,4‐naphthalenediol, 1,2‐dihydroxynaphthalene, and coumarin, characterized by thin‐layer chromatography and gas chromatography‐mass spectrometry. Based on the findings of the AR27 biodegradation pathway it is proposed that Armillaria sp. F022 can be used to treat AR27 dye contaminated effluents to protect the ecosystem.

“…Co-metabolism, which has extended the range of degrading substrates by microorganisms, has been confirmed in many pollutant degradation processes, including chlorinated compounds [ 24 , 25 ], aromatic hydrocarbons [ 26 , 27 ] and gasoline additives [ 28 ], including MTBE [ 8 , 11 ].…”

Co-metabolic bioremediation is supposed to be an impressive and promising approach in the elimination technology of methyl tert-butyl ether (MTBE), which was found to be a common pollutant worldwide in the ground or underground water in recent years. In this paper, bacterial strain DZ13 (which can co-metabolically degrade MTBE) was isolated and named as Pseudomonas sp. DZ13 based on the result of 16S rRNA gene sequencing analysis. Strain DZ13 could grow on n-alkanes (C5-C8), accompanied with the co-metabolic degradation of MTBE. Diverse n-alkanes with different carbon number showed a significant influence on the degradation rate of MTBE and accumulation of tert-butyl alcohol (TBA). When Pseudomonas sp. DZ13 co-metabolically degraded MTBE with n-pentane as the growth substrate, a higher MTBE-degrading rate (Vmax = 38.1 nmol/min/mgprotein, Ks = 6.8 mmol/L) and lower TBA-accumulation was observed. In the continuous degradation experiment, the removal efficiency of MTBE by Pseudomonas sp. Strain DZ13 did not show an obvious decrease after five times of continuous addition.

“…Compared with extracellular ligninolytic enzymes, cytochrome P450 monooxygenases of white rot fungi were more difficult to isolate, which might account for the lack of data on PAHs oxidation by such enzymes. Until recently, the reports on pyrene and anthracene oxidation by cytochrome P450 monooxygenases of white rot fungi were present .…”

The metabolic peculiarities of anthracene and pyrene by Pycnoporus sanguineus H1 were investigated. The fungus H1 could grow on potato dextrose agar plates with anthracene and anthraquinone as carbon sources. In liquid medium, the strain degraded 8.5% of anthracene as the sole carbon source, with no ligninolytic enzymes detected, indicating that intracellular catabolic enzymes might be responsible for the initial oxidation of anthracene. When bran was added to the medium, the degradation rate of anthracene and pyrene increased to 71.3% and 30.2%, respectively, and the laccase activities increased to a maximal value of 501.2 and 587.6 U/L, respectively. By gas chromatography-mass spectrometry analysis, anthraquinone was detected as the unique intermediate product of anthracene oxidation, with a yield molar ratio of 0.3. In vitro experiments showed that the extracellular culture fluid containing laccase transformed anthracene to anthraquinone with a yield molar ratio of 1.0, which was less than that of the in vivo experiment, indicating that anthraquinone could be further metabolized by the strain. Pyrene could not be oxidized by culture fluid. These results showed that both extracellular laccase and intracellular catabolic enzymes might play an important role in the initial oxidation of anthracene, whereas pyrene could be only oxidized by intracellular catabolic enzymes through cometabolism.
