“…In contrast with a study by Rodriguez et al (1999), it seems that there was no clear correlation between laccase activity with dyes decolorization such that BRB81 showed the highest decolorization with a relatively lower laccase activity. It might be that the incubation time was shorter within 96 hours, compared to previous studies that we're able to observe higher peaks within 9-20 days (Jaramillo et al 2017;Merino-Restrepo et al 2020).…”

“…The results were pertinent to previous studies, showing that laccase production might be varied among the fungal strains (Osma et al Risdianto et al 2012;. Moreover, culture conditions and other factors which may impact the expressed enzyme activity should be considered (Rogalski et al 1991;Merino-Restrepo et al 2020). Along the incubation time, decreasing trends of laccase activity were observed for three isolates, except in RB5 by BRB11 (Figure 5).…”

Abstract. Nurhayat OD, Ardiati FC, Ramadhan KP, Anita SH, Okano H, Watanabe T, Yanto DHY. 2021. Bioprospecting three newly isolated white-rot fungi from Berbak-Sembilang National Park, Indonesia for biodecolorization of anthraquinone and azo dyes. Biodiversitas 22: 613-623. Extensive use of textile dyes without proper wastewater treatment may jeopardize the water environment. In this study, bioprospecting newly isolated white-rot fungi from Berbak-Sembilang National Park for decolorizing four synthetic dyes was investigated. A total of 108 wood-decaying fungi were screened by using selective media, resulting in three isolates as the most promising fungal strains (BRB 11, BRB 73, BRB 81). BRB 81 had the best ability to decolorize 91.4% of AB129 and 77.8% of RB5 within 96 hours while the highest removal of RBBR and AO7 was performed by BRB11 around 60% and 37.6%, respectively. The enzymatic degradation was assumed to involve the decolorization process as laccase activities were observed with the highest around 116 UL-1. Based on molecular identification, these three fungal isolates were identified as Phellinus noxius BRB 11, Ceriporia lacerata BRB 81, and Leiotrametes menziesii BRB 73, respectively. In conclusion, P. noxius BRB 11, L. menziesii BRB 73, and C. lacerata BRB 81 could be used as biological agents in textile wastewater treatment and thus, it is important to conserve them as a part of the biodiversity within the local biosphere reserve.

“…It has been confirmed that when the carbon nitrogen ratio is less than 50 the fungus cannot completely colonize the substrate nor give a successful fructification (Hsieh and Yang, 2004; Rashad et al., 2019). Moreover, it is necessary to have a high C/N ratio so that ligninolytic enzymes such as LiP, MnP, and laccase produced by white production fungi can act efficiently (Singh Nee Nigam & Pandey, 2009), agreeing with the results, the coconut and fique fibers whose C/N ratio is much lower than 50 do not present adequate growth and the fique bagasse that exceeds 50 was the trial that obtained the best result with a more uniform conformation (Bellettini et al., 2019; Li et al., 2019; Merino‐Restrepo et al., 2020).…”

In this work, three lignocellulosic residues, coconut fiber, sugarcane bagasse, and fique bagasse, were used as a carbon source for fungal colonization had been proposed to form a composite material. The lignocellulosic residues presented a high percentage of carbon. The lignocellulosic residues had been conditioned and characterized morphologically. The particle sizes chosen were 16 and 50 sieves. The mycelial growth kinetics of the fungi had been evaluated in the residues, where a higher growth rate was observed in the medium enriched with coconut fiber and lower in those containing bagasse. When studying these intrinsic factors, it was observed that an inadequate carbon-nitrogen (C/N) ratio affected mycelial growth. This method of obtaining biomaterials is a promising alternative to lignocellulosic substrates as substrates for fungi with delignification capacity.

Six fungal strains were isolated from the textile industry effluent in which they naturally occur. Subsequently, the fungal strains were identified and characterized in order to establish their potential decolorizing effect on textile industry effluents. The strains of interest were selected based on their capacity to decolorize azo, indigo, and anthraquinone dyes. Three of the strains were identified as Emmia latemarginata (MAP03, MAP04, and MAP05) and the other three as Mucor circinelloides (MAP01, MAP02, and MAP06), while the efficiency of their decolorization of the dyes was determined on agar plate and in liquid fermentation. All the strains co-metabolized the dyes of interest, generating different levels of dye decolorization. Plate screening for lignin-degrading enzymes showed that the MAP03, MAP04, and MAP05 strains were positive for laccase and the MAP01, MAP02, and MAP06 strains for tyrosinase, while all strains were positive for peroxidase. Based on its decolorization capacity, the Emmia latemarginata (MAP03) strain was selected for the further characterization of its growth kinetics and ligninolytic enzyme production in submerged fermentation under both enzyme induction conditions, involving the addition of Acetyl yellow G (AYG) dye or wheat straw extract, and no-induction condition. The induction conditions promoted a clear inductive effect in all of the ligninolytic enzymes analyzed. The highest level of induced enzyme production was observed with the AYG dye fermentation, corresponding to versatile peroxidase (VP), manganese peroxidase (MnP), and lignin peroxidase (LiP). The present study can be considered the first analysis of the ligninolytic enzyme system of Emmia latemarginata in submerged fermentation under different conditions. Depending on the results of further research, the fungal strains analyzed in the present research may be candidates for further biotechnological research on the decontamination of industrial effluents.
