“…They also demonstrated that the laccase activity is quantifiable from the first sampling intervals and gradually increases until reaching values close to 38 U mL ; however, at a very high concentration of dyes, an inhibition of growth and 100 % decrease of the laccase activity was observed. A similar result was reported by Morales-Álvarez et al (2016) when they evaluated the effect of increasing concentrations of MG on the radial growth of G. lucidum. They found that at concentrations ranging between 10 and 50 mg L -1 , the growth of the fungi decreases when cultured in a chemically defined medium as agar Rhada.…”

The triphenylmethane Malachite Green (MG) and Crystal Violet (CV) dyes are cationic dyes and mix with domestic wastewater when dumped; increasing, among others, the chemical and biological oxygen demand and can cause acute toxicity at different trophic levels. Promoting the removal (decolorization) of MG and CV, and laccase activity (54.8 ± 8.9 and 30.6 ± 2.9 UL -1 respectively) by using P. ostreatus viable biomass needed parameters such as pH (4.5 and 6.0), temperature ). In adsorption studies, it was showed that an acidic pH favors the adsorption of both dyes and the model of pseudo-second order describes best the phenomenon of adsorption. Finally, the germination index (GI), using Lactuca sativa seeds for the initial dyes solutions, was < 50%; demonstrating its high phytotoxic effect. When dye solutions were treated with viable biomass, the GI increased, leaving open the possibility to perform future research to determine if the aqueous solutions, post-treated with P. ostreatus, could be used in treatments that generate less toxic water which could be used in processes that do not require potable water.

“…Therefore, fungal laccases have generated a great interest in biotechnological applications for industries such as, 89 textile, paper fabrication, food and pharmaceutical among others (El-Batal et al, 2015). Laccase has become an object for investigation, given it´s great stability and wide ranges of suitable substrates, which influences its ability to lignin degradation, toxic phenol extraction, synthetic dye degradation of azo-, indigo, triphenylmethane and anthraquinone types, cellulose pulp bleaching and pulping black liquor detoxification, juice and wine clarification, organic synthesis processes, residual water treatment and treatment of Polycyclic Aromatic Hydrocarbon (PAHs) contamination, among many others (Balan et al, 2012;Dwivedi et al, 2011;Gianfreda et al, 1999;Hautphenne et al, 2016;Morales-Álvarez et al, 2016;2017;2018;Popa and Cornea, 2015;Rivera-Hoyos et al, 2018). Laccases are useful, to develop different useful alternatives in industrial and bioremediation processes, without affecting the environment (Rivera-Hoyos et al, 2013).…”

“…Secondary treatment with ligninolytic co-culture Fungal strains of Pleurotus ostreatus (HPB/P3) were obtained from the culture collection at Pontificia Universidad Javeriana (Bogotá, Colombia), and Phanerochaete chrysosporium (CDBB-H-298) were obtained from the culture collection of Department of Biotechnology and Bioengineering, CINVESTAV-IPN (México D.F., México). The two strains were cultured in wheat bran extract agar (WBEA) and wheat bran extract broth (WBEB) according to Morales et al (2017). The inoculum was incubated for eight days at 120 rpm and 28 • C.

“…Ligninolytic fungi are more efficient than aerobic and anaerobic bacteria at removing and bio-transforming dye waste due to their oxidative enzymes with low substrate specificity (i.e. peroxidases and polyphenol-oxidases) (Morales et al, 2016;Morales et al, 2017;Rivera-Hoyos et al, 2013). This group of fungi is also capable of removing heavy metals and reducing COD and BOD 5 , thus increasing waste biodegradability ratios to values higher than 0.5 (Maalej et al, 2009;Puentes et al, 2012a;Sathian et al, 2014).…”

A novel textile wastewater treatment using ligninolytic co-culture and photocatalysis with TiO2

Textile industries produce effluent wastewater that, if discharged, exerts a negative impact on the environment. Thus, it is necessary to design and implement novel wastewater treatment solutions. A sequential treatment consisting of ligninolytic co-culture with the fungi Pleurotus ostreatus and Phanerochaete crhysosporium (secondary treatment) coupled to TiO 2 /UV photocatalysis (tertiary treatment) was evaluated in the laboratory in order to discolor, detoxify, and reuse textile effluent wastewater in subsequent textile dyeing cycles. After 48 h of secondary treatment, up to 80 % of the color in the wastewater was removed and its chemical and biochemical oxygen demands (COD, and BOD 5 ) were abated in 92 % and 76 %, respectively. Laccase and MnP activities were central to color removal and COD and BOD 5 abatement, exhibiting activity values of 410 U L −1 and 1 428 U L −1 , respectively. Subjecting wastewater samples to 12 h of tertiary treatment led to an 86 % color removal and 73 % and 86 % COD and BOD 5 abatement, respectively. The application of a sequential treatment for 18 h improved the effectiveness of the wastewater treatment, resulting in 89 % of color removal, along with 81 % and 89 % COD and BOD 5 abatement, respectively. With this sequential treatment a bacterial inactivation of 55 % was observed. TiO 2 films were reused continuously during two consecutive treatment cycles without thermic reactivation. Removal percentages greater than 50 % were attained. Acute toxicity tests performed with untreated wastewater led to a lethality level of 100 % at 50 % in Hydra attenuata and to a growth inhibition of 54 % at 50 % in Lactuca sativa. Whereas sequentially treated wastewater excreted a 13 % lethality at 6.25 % and an inhibition of 12 % at 75 % for H. attenuata and L. sativa, respectively. Finally, sequentially treated wastewater was reused on dyeing experiments in which 0.86 mg g −1 adsorbed dye per g of fabric, that is equivalent to 80 % of dye adsorption. AM.
