In this work, rhamnolipid biosurfactant as an eco‐friendly and biodegradable cleaning agent was produced by Pseudomonas aeruginosa bacteria and was used to evaluate the chemical cleaning efficiency of whey fouled ultrafiltration membranes. Thin layer chromatography (TLC) and Fourier transform infrared spectroscopy (FTIR) confirmed the successful synthesis of rhamnolipid. The produced rhamnolipid was compared to chemical cleaners including sodium hydroxide (NaOH), sodium dodecyl sulfate (SDS) and Tween 20. Ultrafiltration membranes used for fouling and cleaning analysis were prepared using phase inversion via immersion precipitation technique. For studying the fouling mechanisms, Hermia's model adapted to cross‐flow was used. From the fouling mechanism experiments, it was found that the complete blocking and cake formation were the dominant fouling mechanisms. The highest values of cleaning efficiency were achieved using rhamnolipid and NaOH as cleaning agents with the flux recovery of 100%, but with considering the low concentration of the rhamnolipid used in the cleaning solution compared to NaOH (0.3 versus 4 g/L for NaOH), its application is preferred.

“…On the other hand, several authors had mentioned that one of the most challenging problems related to the use of chemically‐based surfactants in cosmetic formulations, is their potential to cause skin irritations and allergic reactions . Hence, their accumulation in the environment imposes adverse effects on natural resources and fabric treated with harsh chemicals is unsafe for human health . In recent years, concerns regarding the environment on the part of consumers and new environmental control legislation have led to the development of natural surfactants as an alternative to existing products .…”

Surfactants play a very important role in laundry and household cleaning products ingredients. In this research, the application of lipopeptide biosurfactants, produced by Bacillus subtilis SPB1, in the formulation of a washing powder was investigated. The SPB1 biosurfactant was mixed with sodium tripolyphosphate as a builder and sodium sulfate as filler. The efficiency of the formulated detergent composition with different washing conditions to remove a stain from cotton fabric was examined. The results showed that the formulated detergent was effective in oil removal, with optimal washing conditions of pH, temperature, striate and time of washing system of 7, 65°C, 1000 RPM and 60 min, respectively. A comparative study of different detergent compositions (biosurfactant-based detergent, combined biosurfactantcommercial detergent, and a commercial detergent) for the removal of oil and tea stains, proved that the bio-scouring was more effective (>75%) in terms of the stain removal than the commercial powders (<60%). Moreover, the results demonstrated that the biosurfactant acts additively with a commercial detergent and enhances their performance from 33 to 45% in removing oil stain and from 57 to 64% in removing tea stain. As a conclusion, in addition to the low toxicity and the high biodegradability of the microbial biosurfactants, the results of this study have shown that the future use of this lipopeptide biosurfactant as laundry detergent additive is highly promising.

“…The waxes and pectins are responsible for the hydrophobic nature of raw cotton, which impedes uniform and efficient dyeing and finishing, since these processes are performed in an aqueous medium . It is therefore necessary to remove these impurities from the raw cotton to ensure the absorption of the dye solutions and other reagents during the subsequent textile processing …”

Study and application of an enzymatic pool in bioscouring of cotton knit fabric

Grey cotton contains between 4-12 % non-cellulosic impurities. The removal of these impurities is generally carried out by alkaline washing at elevated temperatures which may cause damage to the cellulose fibre and generate an effluent with a high environmental impact. An alternative approach is the use of bioscouring, with enzymes specifically removing the impurities under mild conditions of pH and temperature. In this study, the effect of a commercial enzymatic pool (cellulase, lipase, and pectinase) on the bioscouring of 100 % cotton knit fabric was evaluated. The effect of each enzyme and the interaction between them were evaluated with the aid of an experimental design and the characterization of the treated fabric (weight loss, degree of whiteness, degree of pectin removal, and hydrophilicity) was performed. The combination of the three enzymes on bioscouring led to the best results in terms of degree of whiteness (25.0 8Berger), pectin removal (87 %), and hydrophilicity (14 s). A comparison between the enzymatic treatment and the scouring confirmed that bioscouring can be as effective as the conventional process, being more environmentally sustainable because it occurs at neutral pH and consumes less water and energy.
