Antifungal Activity of Some Trityl-Based Synthetic Dyes (original) (raw)

The antifungal activity of 14 anthracene-based synthetic dyes and 6 reference compounds was measured on 36 fungal strains and the data matrix was evaluated separately by principal component analysis (PCA) and using a spectral mapping technique (SPM). The dimensionality of the maps of principal component loadings and variables and the selectivity maps was reduced to two by non-linear mapping. Except for two compounds, the dyes showed marked antifungal activity. Calculations proved that both the strength and selectivity of the biological effect of anthracene-based dyes were highly dependent on the chemical structure of the dye and on the type of fungi. PCA and SPM revealed different aspects of the antifungal activity, therefore, their simultaneous application in future quantitative structure–activity relationship studies is highly recommended
Studies on the antifungal activity of natural dyes and their application ontextile materials
2016
The present study was taken up to assessment of antifungal activity of quaternary chitosan acrylic acid (Q CS-PAA) nano particles mordant dyed fabrics. The results indicate that the samples treated with Q CS-PAA exhibit higher inhibition activity than the untreated samples. The percentage of mycelium growth inhibition at higher concentration of 8oo ppm was varied from 68.06% on Fusarium solani to 64.09% on Penicillium decumbens. Findings of present study indicate that there are variation in tolerance to nano-QCS-PAA between different fungi Treatments with logwood dye in combination with alum and ferric chloride mordants inhibit fungal growth of both fungi. On the other hand, treatment with cochineal dye alone and in combination with mordants were not effective against the above mentioned fungi (0.00 mm zone of inhibition). The results showed an increase in inhibition % when dyeing cotton tissue was dyed with rhubarb dye by 6.95%, while opposite trend was occurred when the polyester ...

The present study was aimed to assess the anti-bacterial activity and dyeing property of the pigments obtained from five fungal species. Cotton fabric and leather samples were dyed with the purified pigments and their anti-bacterial activity was assayed under in-vitro conditions. Post-mordant cotton fabric and leather samples exhibited maximum bacterial reduction when compared with the pre-mordant and dyed samples. Pigment exhaustion, colour coordinates and fastness properties of the dyed cotton fabric and leather samples were also assessed. The toxicity of the pigments was evaluated by seed germination assay.

The increasing interest in the use of natural dyes is not accompanied by sufficient information and method for the application due to broad natural dyes resources existence. Gambir (Uncaria gambir), one of promising favorable natural dyes, has been used as batik coloring for decades. However, the application of gambir extract as a textile colorant faces a severe problem to be encountered which is the microbial growth such as fungi, mold, and bacteria. This study proposed several antifungal agents to suppress the growth of the fungus such as chitosan, aloe vera, and formaldehyde. To conduct the fungus inhibition concentration of every antifungal agent, Aspergillus niger was introduced on the colored cloth medium with the addition of Potato Dextrose Broth (PDB) growth media. Three methods of antifungal addition during the coloring process were investigated namely pre-coloring, post-coloring, and mix coloring process. The growth of Aspergillus niger was observed and measured the diamet...
Fungal Pigments and Their Prospects in Different Industries
Microorganisms, 2019
The public’s demand for natural, eco-friendly, and safe pigments is significantly increasing in the current era. Natural pigments, especially fungal pigments, are receiving more attention and seem to be in high demand worldwide. The immense advantages of fungal pigments over other natural or synthetic pigments have opened new avenues in the market for a wide range of applications in different industries. In addition to coloring properties, other beneficial attributes of fungal pigments, such as antimicrobial, anticancer, antioxidant, and cytotoxic activity, have expanded their use in different sectors. This review deals with the study of fungal pigments and their applications and sheds light on future prospects and challenges in the field of fungal pigments. Furthermore, the possible application of fungal pigments in the textile industry is also addressed.
