“…Anthraquinone from Fusarium oxysporum can be used to dye wool fabrics (Nagia and El-Mohamedy, 2007). Recently, Sudha, Gupta and Aggarwal (2016) reported dyeing of wet blue goat nappa skin with the Penicillium minioluteum pigment. A red pigment from Talaromyces verruculosus shows an adequate color tone for cotton fabric without any cytotoxic effect (Chadni et al, 2017).…”

The demand for natural colors is increasing day by day due to harmful effects of some synthetic dyes. Bacterial and fungal pigments provide a readily available alternative source of naturally derived pigments. In contrast to other natural pigments, they have enormous advantages including rapid growth, easy processing, and independence of weather conditions. Apart from colorant, bacterial and fungal pigments possess many biological properties such as antioxidant, antimicrobial and anticancer activity. This review outlines different types of pigments. It lists some bacterial and fungal pigments and current bacterial and fungal pigment status and challenges. It also focuses on possible fungal and bacterial pigment applications.

“…As can be observed in Figure 4 , SPI films provided an excellent UV barrier from 200 to 300 nm, due to the high percentage of aromatic amino acids (tyrosine, tryptophan and phenylalanine) present in soy protein [ 31 , 32 ]. Moreover, this UV barrier was improved in EPS-containing films probably due to the presence of hydroxyl groups in EPS, which have been described to act as auxochrome groups [ 33 , 34 ].…”

Compression Molded Soy Protein Films with Exopolysaccharides Produced by Cider Lactic Acid Bacteria

Two exopolysaccharide (EPS)-producing lactic acid bacteria (LAB) strains, Liquorilactobacillus (L.) sp CUPV281 and Liquorilactobacillus (L.) mali CUPV271, were isolated from Spanish apple must. Each of the strains produced a dextran, with different branching degrees, to be incorporated into soy protein isolate (SPI) film-forming formulations. Films were prepared by compression molding, a more rapid processing method than solution casting and, thus, with a greater potential for scaling-up production. Thermal analysis showed that SPI and EPS start the degradation process at temperatures above 190 °C, confirming that the compression temperature selected (120 °C) was well below the corresponding degradation temperatures. Resulting films were transparent and homogeneous, as shown by UV-Vis spectroscopy and SEM, indicating the good compatibility between SPI and EPS. Furthermore, FTIR analysis showed that the interactions between SPI and EPS were physical interactions, probably by hydrogen bonding among the polar groups of SPI and EPS. Regarding antifungal/fungistatic activity, LAB strains used in this study showed an inhibitory effect on germination of fungal spores.

“…The decline in frequent use of such products is due to the awareness spread by the environmental associations to impose restrictions on their use . On the other hand natural dyes are easily biodegradable and bioactive , having no hazardous effect on health and can be handled easily without any environmental damage . They produce soothing and soft shades in contrast to synthetic dyes .…”

Environmental pollution spread due to frequent use of synthetic dyes has compelled the global community to move toward sustainable and eco‐friendly products. The present research has been conducted to investigate the coloring efficacy of Arjun bark (Terminalia arjuna) for silk fabric under the influence of ultrasonic radiation. Extracts have been prepared in different media and extracts and silk fabrics have been irradiated ultrasonically for 15–60 min at 60 °C. Good color strength is obtained, by dyeing irradiated silk for 65 min at 65 °C, when irradiated extract of pH 3 (RE, 30 mL) obtained from powder (6 g) is used in the presence of salt concentration of 3 g/100 mL. Pre‐chemical mordants such as 5% of Al (Aluminum sulphate) and 9% of Fe (iron sulphate) as well as post‐chemical mordants such as 5% Al (Aluminum sulphate) and 3% of Fe (iron sulphate) have improved the color characteristics. The bio‐mordants employed reveal that 9% of pomegranate and turmeric extracts as pre and post bio‐mordants have given excellent coloring characteristics. It is concluded that Arjun bark has a great potential to act as a source of natural colorant for silk dyeing under the influence of ultrasonic radiation. © 2018 American Institute of Chemical Engineers Environ Prog, 38: S331–S339, 2019
