“…The results of the antibacterial efficiency of ZnO Ps showed that at lower concentrations, ZnO Ps were more effective against Gram-positive than Gram-negative bacteria ( Figure 5) [11,15,67,85,100], since the former are more susceptible to inhibition by ZnO Ps than the latter. However, the growth inhibition of Gram-negative bacteria significantly increased at higher ZnO concentrations and with longer contact times, resulting in excellent antimicrobial activity against both Gram-positive and Gram-negative bacteria [84,99].…”

“…The antibacterial activity of textile fibers has been most often tested against Staphylococcus aureus Gram-positive bacteria [14][15][16]42,67,68,72,75,76,82,94,99,126,127,129] and Escherichia coli Gram-negative bacteria [15,16,42,67,68,76,94,99,109,124,126,127,129]. In addition, testing against methicillin-resistant Staphylococcus aureus (MRSA) [82], Staphylococcus epidermidis [82], Propionibacterium acnes [82], Candida albicans [16,42,94,124], Bacillus subtilis [67], Pseudomonas aeruginosa [67], Saccharomyces cerevisiae [125], Gluconobacter cerinus [88], and Klebsiella pneumonia [72] has been performed. The antifungal activity has been tested against Aspergillus flavus [126].…”

“…To decrease the particle size and avoid particle agglomeration, in situ synthesis of ZnO NPs in the presence of appropriate reducing agents as well as stabilizing and capping agents has been recommended to achieve excellent UV protection [51,83,88]. Among stabilizing and capping agents, different chemicals, such as hexamethyltriethylene tetramine [83], polydopamine (Figure 8) [88], folic acid [87], plant extracts [11,73], proteins isolated from fungus [67], and surfactants [83] have been used in the ex situ and in situ syntheses of ZnO NPs. Some stabilizing agents, such as plant extracts, also exhibit UV-absorbing and UV-blocking properties themselves [73,138].…”

The use of ZnO for the functionalization of textile substrates is growing rapidly, since it can provide unique multifunctional properties, such as photocatalytic self-cleaning, antimicrobial activity, UV protection, flame retardancy, thermal insulation and moisture management, hydrophobicity, and electrical conductivity. This paper aims to review the recent progress in the fabrication of ZnO-functionalized textiles, with an emphasis on understanding the specificity and mechanisms of ZnO action that impart individual properties to the textile fibers. The most common synthesis and application processes of ZnO to textile substrates are summarized. The influence of ZnO concentration, particle size and shape on ZnO functionality is presented. The importance of doping and coupling procedures to enhance ZnO performance is highlighted. The need to use binding and seeding agents to increase the durability of ZnO coatings is expressed. In addition to functional properties, the cytotoxicity of ZnO coatings is also discussed. Future directions in the use of ZnO for textile functionalization are identified as well.

“…The textile wastewater can change the chemicals, physicals and biologicals character of the getting water bodies by increasing the BOD, COD, TDS, TSS as well as alters the pH and gives the intense colorations to water bodies [18]. Different metabolites produced by microbes have high potentiality in various biological activities [19][20][21][22][23]. Degradation by fungi is known as myco-remediation.…”

I N this study, fungal isolate D2-1 was isolated from contaminated soil collected from textile industry companies and showed high potentiality for decolorization of two different azo dyes. This isolate was identified as Aspergillus niger D2-1 using morphological and cultural characteristic as well ITS gene sequencing. Decolorization process under different optimized condition of azo dye concentration, pH, incubation periods, inoculum size and different carbon and nitrogen sources were investigated. The maximum decolorization efficiency against 100 ppm dye concentration of reactive yellow (4GL) and reactive red (4BL) dyes of 98.62 %and 92.42 %, respectively, were recorded for Aspergillus niger D2-1 at pH 9.0, in presence of 2 % glucose and 0.5% yeast extract as carbon and nitrogen sources respectively at room temperature after 7 days on shaking conditions. The decolorization percentage was confirmed by ultraviolet-visible (UV-Vis) spectrum analysis of untreated/treated reactive yellow (4GL) and reactive red (4BL) dyes, which showed complete disappearance of peaks at ~ 425 nm and at ~ 520 nm, indicates the degradation of dyes due to fungal activity. Treatment of textile wastewater effluent by Aspergillus niger D2-1showed high decolorization percentage (59%) for effluent, also physico-chemical characteristics of textile effluent such as chemical oxygen demand (COD), total dissolved solids(TDS) and total suspended solids (TSS) were decreased from 756 mg/L, 1597 mg/Land 821 mg/L to 391 mg/L, 845 mg/L and 362 mg/L respectively. Moreover, Gas chromatography-mass spectroscopy (GC-MS) of textile effluent before and after treatment were recorded and confirmed the potentiality of Aspergillus niger D2-1 in dyes wastewater treatment.
