Compared to classical surfactants, Gemini surfactants have superior properties. The amino acid Gemini surfactants are believed to be adopted more widely. The Gemini surfactant with tripeptide structure, sodium di(lauroyl glutamyl) lysine (DLGL), was prepared by amidation utilizing methyl laurate, glutamate and lysine and characterized by 1H NMR, 13C NMR and MS. Additionally, the pKa value, surface activities, aggregation, foaming properties and emulsifying attributes of the DLGL surfactant in aqueous solution with varied pH values were examined. The results indicate that the protonation-deprotonation behavior of the DLGL surfactant is highly dependent on pH values. The surface tension, critical micelle concentration (cmc), foamability and foam stability exhibited superior performance at pH 6 and 7.

The raw bagasse FA underwent a modification process involving reflux with TiO2 in NaOH at 100°C for 24 h, resulting in a modified fly ash (MFA). Comparative analyses of the sorbents were conducted using scanning electron microscopy (SEM), transmission electron microscopy (TEM), powder X-ray diffraction (pXRD), Brunauer–Emmett–Teller (BET) surface analysis, and Fourier-transform infrared spectroscopy (FT-IR). The surface area of the original FA was found to be 10.795 m2 g−1, which increased to 30.597 m2 g−1 postmodification. Similarly, the crystallinity of FA was initially 49.36% and enhanced to 79.70% after the modification process. The adsorption process of SDBS onto both FA and MFA were found to follow pseudo-second-order kinetics. Moreover, the Langmuir adsorption isotherm was the most fitting model, as evidenced by the R2 values at 298 K for SDBS-FA (0.99) and SDBS-MFA (0.99), both of which are remarkably close to unity. The dimensionless separation factor (RL) was determined to be less than one, indicating favorable adsorption. The maximum adsorption capacities predicted by the Langmuir model are 156.00 mg/g for FA and a notably higher 231.48 mg/g for MFA. Thermodynamic analysis revealed a positive change in enthalpy (ΔHo) for SDBS-FA and SDBS-MFA of 54.50 and 124.48 KJ mol−1, respectively, suggesting endothermic adsorption. Additionally, the Gibbs free energy (ΔGo) was negative for both SDBS-FA and SDBS-MFA, suggesting that the adsorption of SDBS is spontaneous.","PeriodicalId":17083,"journal":{"name":"Journal of Surfactants and Detergents","volume":"28 1","pages":"171-188"},"PeriodicalIF":1.6,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141862971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A factorial design was used to optimize agitation, temperature, and inoculum size in a mineral medium containing 1.5% corn steep liquor in 100-mL shake flasks. The best conditions (175 rpm, 28°C, and 4% inoculum) were used to scale up biosurfactant production in a 50-L bioreactor. Surface tension of the fermentation medium decreased from 69.5 to 30.2 mN/m within 72 h. The biosurfactant exhibited a critical micelle concentration (CMC) of 0.900 ± 0.08 g/L. The biosurfactant formed stable oil-in-water emulsions of motor oil and petroleum, achieving emulsification indices of 90.80% and 99.00%, respectively. An eco-friendly detergent was formed that included biosurfactant at several different concentrations, 0.2 (wt) % hydroxyethyl cellulose and 0.2% potassium sorbate. The detergent remained stable under extreme conditions of pH, temperature, and salinity when stored for 90 days. The detergent was nontoxic to cabbage, cherry tomato plants, and the microcrustacean Artemia salina. A detergent formulation containing biosurfactant at the CMC completely dispersed motor oil in seawater at a 1:1 surfactant/oil (vol/vol) ratio and removed 99.21% of motor oil (20 mL) contained in 60 g of clayey soil.

The generation of electrostatic interaction and associated intermolecular arrangement between the probe and anionic surfactant is responsible for the fluorescence enhancement and subsequent selectivity towards the anionic surfactant. Concurrently, the probe was unaltered by the presence of cationic and non-ionic systems. Utilizing this property, we were able to construct a facile and efficient method for the detection of anionic surfactants, featuring LOD values up to 1.1 μM concentrations in dimethylsulfoxide solvent. The light-up detection was also confirmed via lifetime studies, with superior increments in average lifetime decay values (0.33–2.7 ns).

This study explored to increase the proportion of di-rhamnolipids biosynthesized from Pseudomonas aeruginosa and evaluate the relationship between activity and di-rhamnolipids proportions. P. aeruginosa SGrhlC was constructed by increasing the rhlC gene in P. aeruginosa SG. HPLC-MS results indicated that SGrhlC produced more di-rhamnolipids (62.32%) than that of the wild-type strain SG (45.24%). Both the species and proportion of di-rhamnolipids were increased, mainly Rha-Rha-C8-C10 and Rha-Rha-C10-C10. The rhamnolipids produced by SGrhlC was thermostable and salt-tolerant. The SGrhlC rhamnolipids decreased surface tension of water to 27.0 mN/m with a critical micelle concentration (CMC) of 50 mg/L and emulsified crude oil with an emulsification index of 66.9 ± 1.5%. The SGrhlC rhamnolipids exhibited antimicrobial activity against Staphylococcus aureus and Cladosporium sp. with IC50 (half maximal inhibitory concentration) values less than 15 mg/L, and washed 73.02% ± 1.77% of oil from petroleum-contaminated soil. Physicochemical activities of three bacterial rhamnolipids varied with their di-rhamnolipids proportions. Results indicated that the higher proportions of di-rhamnolipids were, the lower CMC, better surface activity and higher washing oil rate were, while the weaker emulsifying activity and lower antimicrobial activity were. The SGrhlC rhamnolipids showed better surface activity and a lower critical micelle concentration, which was superior for wetting, foaming, desorbing and dispersing. This study revealed that P. aeruginosa can be genetically regulated to biosynthesize rhamnolipids with specific structure. Perspectives of the customized biosynthesis and applications of rhamnolipids were also discussed.","PeriodicalId":17083,"journal":{"name":"Journal of Surfactants and Detergents","volume":"27 5","pages":"813-821"},"PeriodicalIF":1.6,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141609834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their ability to form thin films on surfaces with ordered and controllable patterns determines their applicability. Here, we report two pyridinium oxime-based surfactants, which possess similar aggregation properties in solution, but exhibit substantially different assembly on highly oriented pyrolytic graphite (HOPG) surface. The two compounds are regioisomers with the oxime unit placed either in meta or para position of the pyridinium ring. While the para isomer assembled to anisotropic one-dimensional (1D) islands and long rod-like structures, the meta isomer formed two-dimensional (2D) islands on the HOPG surface. This difference is rationalized through molecular level force-field calculations that show anisotropy in the growth of the para isomer resulting from an effective overlap of the alkyl chains and oxime groups, which is distinctly not feasible in the assembly of the meta isomer. The assembly of these compounds is compared with another oxime-containing compound of similar structure, but without the charged pyridinium unit. The charged unit seems to be crucial for the preferential formation of multilayer islands even at low coverage.","PeriodicalId":17083,"journal":{"name":"Journal of Surfactants and Detergents","volume":"28 1","pages":"123-132"},"PeriodicalIF":1.6,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141572671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
