Intensification of pyrene degradation by native Candida tropicalis MTCC 184 with sonication: Kinetic and mechanistic investigation

Current advances in Candida tropicalis: Yeast overview and biotechnological applications

“…Pyrene is another aromatic compound and a priority pollutant, released in marine environments by the incomplete combustion of fossil fuels and biomass. Kashyap and Moholkar 119 demonstrated the potential ultrasonic bioremediation by C. tropicalis with a pyrene degradation of 53%.…”

Molecular advances in mycoremediation of polycyclic aromatic hydrocarbons: Exploring fungal bacterial interactions

“…Pycnoporus sanguineus H1 Anthracene degradation rate decreased after piperonyl butoxide, P450 inhibitor addition [50] Aspergillus glaucus AL1 Phenol-2-monoxygenase and catechol-1,2-dioxygenase are involved in degradation [32] Pyrene Fusarium solani and Hypocrea lixii Metal tolerant strain degraded 60% of pyrene after 2 weeks [51] Pseudotrametes gibbose Increased degradation pyrene in the presence of cosubstrates was observed [52] Pycnoporus sanguineus H1 Pyrene degradation rate decreased in the presence of piperonyl butoxide [50] Coriolopsis byrsina APC5 4,5-Dihydroxypyrene, phenanthrene, benzoic acid, benzoic acid-2-hydroxy pentyl ester, pyruvic acid, phthalic acid Di isopropyl ester were detected as metabolites [53] Trichoderma sp. F03 Fungi degraded 78% pyrene in the presence of surfactant and glucose [54] Ceriporia lacerate RF-7 Degradation was increased in the presence of glucose as cosubstrate [55] Candida tropicalis Two metabolic pathways catalyzed by P450 and 1,2dioxygenase was seen [11] Benzo(a)pyrene Anthacophyllum discolor Degraded 75% of benzo(a)pyrene from medium [56] Armillaria F022 Glucose addition increased degradation 2.5-fold. Benzo (a)pyrene-1,6-quinone, 1-Hydroxy-2-benzoic acid, and benzoic acid were detected as intermediate metabolites [57] Cladosporium sphaerospermum, Paecilomyces lilacinus and Verticillium insectorum…”

“…provide efficient degradation, certain fungal genera including Phanerochaete sp., Pleurotus sp., Ganoderma sp., Aspergillus sp., Penicillium sp., Candida sp., Cunninghamella sp., were also reported to perform PAHs degradation and mineralization. Interestingly, fungi have shown better transformation of PAHs to soluble hydroxylated or oxidized forms which were readily available for uptake by other organisms in the microbial community leading to complete and improved mineralization of PAHs, mainly, due to extensive mycelial growth and ability to produce nonspecific extracellular enzymes (acting on wide substrates) which facilitates better penetration and adaptability of fungi to PAHs like aromatic substrates [7][8][9][10][11].…”
