Synergy between Sophorolipid Biosurfactant and SDS Increases the Efficiency of P. aeruginosa Biofilm Disruption

Biofilms are communities of bacteria encased in selfsecreted extracellular polymeric substances (EPS) that adhere stubbornly to submerged surfaces. Once established, these communities can cause serious chronic illnesses in medical settings, while they can promote corrosion and biofouling in industrial settings. Due to the difficulty of their removal, strongly oxidizing chemicals and detergents can be used to degrade and remove biofilms by killing the cells and degrading the matrix; however, the choice of compounds is limited in delicate environments due to the potential damage they may cause. In the case of detergents, most are synthesized from nonrenewable petrochemicals that have a degree of aquatic toxicity. There is a growing need to identify and characterize alternatives to synthetic surfactants. Biosurfactants, which are surfactants produced by microorganisms, are a promising alternative since they can be synthesized from renewable resources, have low environmental toxicity, and have been shown to have higher degrees of specificity in the mechanism of action. Sophorolipids are a class of glycolipid surfactants produced by yeast that have demonstrated great promise due to large yields from renewable feedstocks and for antimicrobial properties; however, the effect of the application of sophorolipids to Gramnegative bacterial biofilms has not been well studied. We investigate the antibiofilm properties of sophorolipids by demonstrating its ability to cause the catastrophic disruption of Pseudomonas aeruginosa PAO1 biofilms in microfluidic channels. We show that while sophorolipids inflict little damage to the bacteria, they weaken the EPS biofilm matrix, leading to surface-detachment and breakup of the biofilm. Furthermore, we find that sophorolipids act cooperatively with the widely used surfactant, sodium dodecyl sulfate. When combined, concentrations ∼100-fold lower than the minimum effective concentration, when used independently, recover potency. Biosurfactants are typically expensive to produce, thus our work demonstrates a means to improve efficacy while simultaneously reducing both cost and the amount of environmentally harmful substances used.

“…Known today simply as detergents, they can be produced using any soap or non-soap ingredient used as a cleaning agent. Chemically, they are compounds or preparations containing soaps or other ingredients intended for water-based laundry processes (Osadebe et al, 2018). They mainly aim to remove visible stains and provide a hygienically clean surface, including removing the microbiological contamination and malodorous compounds as apparent stains (Bockmühl, 2017).…”

Halal Laundry Detergents: Ingredients and Regulations in Malaysia

Cleaning products are necessary for our daily lives since they are highly effective in cleaning and washing. They assist in personal hygiene by loosening and removing soil and dirt from the surface, diminishing germs or bacteria that are the source of infectious diseases and making the surroundings comfortable. There are three most common detergents in various places: laundry, dishwashing, and household cleaning. Hence, this review paper focuses on laundry detergent to clean the dirt on fabrics and clothes. This paper aims to provide general knowledge for consumers, particularly Muslims, of the ingredients used in laundry detergents and the halal-related regulations in Malaysia. Ingredients used in detergent products, such as enzymes derived from animals, plants, fungi, and bacteria, have issues with where the sources were obtained, which subsequently become one of the reasons many productions have issues fulfilling the halal certification requirement. Other than enzymes, many other ingredients are added to detergent products to provide specific properties and characteristics, such as surfactants, builders, alkalis, bleaches, colourants, and fragrances, which consumers should know before purchasing. Manufacturers must inform Muslim consumers about the purity and impurity of the ingredients used in laundry detergents to make wise decisions in purchasing halal products.

“…BAS initially appeared on the market in the early 1930s but experienced considerable development from the late 1940s forward. In early literature, BAS formulation or syndets (synthetic detergent) were often used as synthetic detergents [5][6][7][8][9][10][11][12][13][14]. The Friedel-Crafts alkylation of benzene with propylene tetramer followed by sulfonation was what they had planned.…”

Biodegradation of Linear Alkylbenzene Sulfonates (LAS): A Mini Review

The most common anionic surfactants in the formulation of detergents are Linear Alkylbenzene Sulfonates (LAS), with an anionic sulfonate head group and a hydrophobic alkylbenzene tail group. The two primary synthetic detergents, together with sodium laureth sulphate, have been around for quite some time and may be found in many personal-care items such as shampoos, soaps, toothpaste, and laundry detergent. LAS is a relatively recalcitrant compound and not easily biodegraded. It is a major source of environmental contamination. Bioremediation can potentially give a significantly higher removal efficiency than standard physicochemical techniques. This review aims to compile information on the toxicity, biodegradation and assimilatory pathway of this class of compound. One of the challenges in the bioremediation of this class of compound is that there have been limited SDBS-degrading bacteria isolated and characterized to date and further work in the field of bioremediation should focus on the isolation of more degraders and carrying out further trials with micro-and mesocosms.
