“…All the strains were inoculated on agar plates (12 mL medium/Petri dish) containing malt extract (12.7 g L −1 ), glucose (10 g L −1 ) and agar (20 g L −1 ) (Malt Extract Agar with glucose (MEA)), supplemented either with 2,6-dimethoxyphenol (1 mM) (DMP) (Fonseca et al 2010) to detect Lac activity, MnCl 2 ·4H 2 O (1 mM) to estimate MnP (Jarosz-Wilkołazka et al 2002) and Azure B (50 μM) to assay LiP (Archibald, 1992). Inocula consisted of a 5 mm colonised agar plug of a 5–7 day-old culture grown on MEA.…”

The aim of the present study was to assess the ability of different white-rot fungi to tolerate polychlorinated biphenyls (PCBs) using predictive mycology, by relating fungal growth inhibition to ligninolityc enzyme secretion. Fungal strains were grown in the presence of PCBs in solid media and their radial growth values were modelled through the Dantigny-logistic like function in order to estimate the time required by the fungal colonies to attain half their maximum diameter. The principal component analysis (PCA) revealed an inverse correlation between strain tolerance to PCBs and the laccase secretion over time, being laccase production closely associated with fungal growth capacity. Finally, a PCA was run to regroup and split between resistant and sensitive fungi. Simultaneously, a function associated with a model predicting the tolerance to PCBs was developed. Some of the assayed isolates showed a promising capacity to be applied in PCB bioremediation.Abbreviations: Polychlorinated biphenyls (PCBs), white-rot fungi (WRF)

“…Laccases are extracellular multicopper oxidoreductases [12] that can act on a broad range of substrates, including phenols, phenolic compounds, diamines, aromatic amines, benzenethiol and even some inorganic compounds such as iodine [13]. Due to these unusual properties, ligninolytic enzymes are effective in degrading/decolourising synthetic dyes [14][15][16]. White rot fungi coming under basidiomycetes are good producers of ligninolytic enzymes.…”

Lenzites elegans, a ligninolytic enzyme producing white rot fungus with proficient synthetic dye decolourization ability was isolated from decaying wood. To the extent of our knowledge, this is the first report of laccase (362.7 IU/mL) and lignin peroxidase (5.17 IU/mL) production by L. elegans KSG32. The synthetic dye decolorizing ability of the fungus was checked using solid and liquid media. The organism showed greater ability for decolourization of naphthol green B (97%) and bromophenol blue (88%) in the submerged condition followed by partial decolourization for two azo dyes, namely, orange G (70%) and congo red (62%). This is an indicative of the potential application of L. elegans KSG32 in decolourization of colored industrial effluent. The FTIR analysis of the decolourized dye sample showed that major bonds in the dye were broken and oxidation process also increased. The analysis of biomass content showed no growth inhibition of L. elegans KSG32 in the presence of dyes, indicating the less toxicity of these dyes on fungal growth. for 15 min. The moisture content was adjusted to 90% using 0.1 M citrate buffer (pH 5). Three mycelial plugs of size 1 cm2 from 6 days old PDA plate culture were used as inoculum. Inoculated flasks were incubated at room temperature for 5 days. Keywords: Extraction of crude enzymeAfter incubation, the crude enzyme was extracted by adding 50mL 0.1 M citrate buffer (pH 5) to each flask. The culture supernatant was collected after centrifugation at 10,000 rpm for 10 min at 4 C and stored at 4 C.

“…However, in the available literature lacks the information about decolorization of alizarin blue by microorganisms, whereas data are available that indicate the decolorization of other anthraquinone dyes by white-and brown-rot fungi: Remazol Brillant Blue R (RBBR), Basic Blue 22, Poly R-478 (a polyanthraquinone dye) (Freitag and Morrell 1992;Jarosz-Wilkołazka et al 2002;Eichlerová et al 2005Eichlerová et al , 2007Lozovaya et al 2006;Rigas and Dritsa 2006;Raju et al 2007;Anastasi et al 2009;Yemendzhiev et al 2009;Korniłłowicz-Kowalska and Rybczyńska 2012). Based on our study, we concluded that certain of the selected strains of microfungi, e.g., H. haematococca and C. rosea f. catenulata, already after 4 days, while T. harzianum after 2 days, caused 40, 50, and 65 %, respectively, decolorization of 0.03 % solutions of the monoanthraquinone dye used.…”

“…Information currently available on the subject of decolorization of post-industrial lignin and dyes with aromatic structure by microscopic fungi is fragmentary and does not provide any more extensive data on the enzymes that participate in that process (Rodriguez et al 1996;Jarosz-Wilkołazka et al 2002;Lopez et al 2006;Lozovaya et al 2006;Anastasi et al 2009;Biyik 2012), whereas studies concerning ligninolytic basidiomycetes show that the processes of decolorization and biodegradation of lignin and related compounds, including anthraquinone dyes, proceed with the participation of peroxidases and (or) laccase (Shin 2004;Champagne and Ramsay 2005;Korniłłowicz-Kowalska and Rybczyńska 2012).…”

A total of 610 strains from 16 species of micromycetes with potential ligninolytic capabilities were isolated from soil, compost, and rotten wood, including 400 strains of soil origin. In the test of decolorization of agarized 0.06 % alizarin blue, 52 strains with high decolorization activity were selected. In liquid cultures with 0.2 % post-industrial lignin and 0.03 % alizarin blue, all of the selected strains showed three different extracellular peroxidase activities such as HRP-like, LiP, and MnP. Laccase was detected only in the cultures with alizarin blue, but those were trace amounts. In the decolorization of alizarin blue, the highest levels of activity were attained by HRPlike peroxidase. In the transformations of post-industrial lignin that included decolorization, colorization (darkening of substrate), and re-colorization, the highest levels of activity were attained by lignin peroxidase, especially at the start of the culture. The transformations of both dye substrates in the cultures of all 52 strains were accompanied by the release of glucose oxidase, but high activities of that enzyme were observed only in the presence of alizarin blue. Whereas in the presence of lignin the fungi under study synthesized catalase, the activity of which attained a maximum toward the end of the culture was negatively correlated with the activity of the remaining oxidoreductases under study. Among the 52 selected strains, three strains such as Haematonectria haematacocca BwIII43, K37, and Trichoderma harzianum BsIII33 were characterized by a high activity of decolorization.
