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":null,"pages":null},"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":null,"pages":null},"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}

Staphylococcus aureus HA25, growing at a pH range of 5.0–8.5, was isolated from Erzurum gogermis cheese and purified using a three‐phase partitioning technique. Optimal immobilization processing conditions were determined for 0.1% wt/wt chitosan, alginate, and chitosan/alginate concentrations of pure lipase enzyme. Morphological features of the immobilized enzyme structure were determined using scanning electron microscopy (SEM) analysis, and structural characterizations were determined using x‐ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, and thermogravimetric (TG) analysis. The results showed that the natural structure of the lipase was largely restored upon reconstitution of the spray‐dried immobilized lipase structures in water. While the free enzyme removed 52.6% of the oil added to the cotton fabric, the immobilized lipase@alginate enzyme removed ~98% of the oil added to the cotton fabric at the highest rate when used as a detergent additive. It was found that the reusability activity of chitosan@lipase, alginate@lipase, and chitosan/alginate@lipase enzymes remained at 86.4%, 92.8%, and 88.6% of their original activity, respectively. The study suggests that immobilized variations of the lipase enzyme within chitosan, alginate, and chitosan/alginate matrices may serve as a natural, secure, and efficient substitute for conventional chemical detergents, offering a non‐toxic alternative for additive materials.","PeriodicalId":17083,"journal":{"name":"Journal of Surfactants and Detergents","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141509923","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}

In this study, we systematically evaluated the effects of eight hydrotropes on the antibacterial activity of fatty acids solubilized in a micellar system.

The solubilization of lauric acid (12:0 FA) in the micelles of nonionic surfactants increased and decreased the antibacterial activities of the surfactants against Staphylococcus aureus (S. aureus) and Staphylococcus epidermidis, respectively. The addition of the hydrotropes decreased the antibacterial activity of the surfactants against both Staphylococci. However, on introducing small amounts of 12:0 FA, the surfactants exhibited selective antibacterial activity against S. aureus. These antibacterial phenomena were observed at concentrations above the critical micelle concentration of the surfactants.

The results showed that APGSHS showed much enhanced solubility and there for better foaming and detergency properties than APG due to the introduction of sulfonate group. Then, the mildness of APGSHS and commercially available mild surfactants was compared using zein test and hemolysis of red blood cells (RBC) test. APGSHS has higher mildness than other surfactants, such as potassium lauroylglycinate (PLG), lauramidopropyl betaine (LAB), and sodium laurylmethyl taurate (LMT). The mechanism of mildness was investigated by studying the interaction between APGSHS and protein using zein model through micelle behavior and protein structure. It was observed that compared to other anionic surfactants such as sodium fatty alcohol polyoxyethylene ether sulfate (AES) and sodium dodecyl sulfate (SDS), APGSHS possesses a larger hydrophilic head group and causes less damage to the secondary structure of zein. Finally, the effect of different surfactants on the hair keratin loss during washing was evaluated. The results showed APGSHS had a minimal damaging effect on keratin in the hair, resulting in the lowest protein loss. This work suggests APGSHS as a promising ingredient for green and mild cleaning products.","PeriodicalId":17083,"journal":{"name":"Journal of Surfactants and Detergents","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141509924","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}

Towards this vision, bio-based surfactants and biosurfactants are being explored as alternatives to traditional petrochemical surfactants. However, the transition towards these technologies is expected to be gradual, therefore there is a critical need to formulate new biosurfactants in combination with traditional surfactant classes such as alkoxylates, sulfates and amine-oxides to achieve a balance of performance, cost, and sustainability. To this end, we report a study of the impact of sophorolipid biosurfactants on the cloud point of alcohol ethoxylates, and on the surface tension and foaming of alkyl sulfate/amine-oxide mixtures. We make the surprising finding that high-acid sophorolipids can act as highly efficient hydrotropes and increase the cloud point of alcohol ethoxylates. In sulfate/amine-oxide mixtures, models of experimental data suggest that both high-acid and high-lactone sophorolipids can replace 40–50% of the primary surfactants without significant changes to the surface tension or foaming performance.

Many research studies have focused on the use of recycled WFO. These studies are highly promoted because of the need to find new ways of reducing the negative impact of WFO on the environment. One of these studies focused on the production of sophorolipid (SL), a naturally derived eco-friendly glycolipid biosurfactant. Unfortunately, the environmental and societal advantages brought about by the wide-spread use of SL are offset by its high production cost. WFO is a high-volume, inexpensive material that can be used as a substrate for SL production. As such, by utilizing WFO as a feedstock material cost reduction can be realized to improve large-scale application potential. One drawback to the use of WFO is that its physical characteristics are different from fresh oil and its effect on SL productivity (g/day) has not been investigated. This research focused on the effect of acid value (AV), peroxide value (PV), and carbonyl value (CV) of WFO on SL productivity. It was confirmed that SL titers (111.1 vs. 106.7 g/L) did not differ significantly after using either fresh oil (CV <0.01) or WFO, respectively. In addition, this research also confirmed that higher WFO degradation required longer culture periods (from 6 days to 9 days) to reach comparable SL concentrations as that produced with fresh oil.","PeriodicalId":17083,"journal":{"name":"Journal of Surfactants and Detergents","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141355401","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 real salt water sample with a high chemical oxygen demand (COD = 1700 mg O2/L) was thus treated. First, the phase diagrams of the binary systems (water–surfactant), and the pseudo‐binary systems (water–surfactant–HC), were determined. Second, after a 24 h settling time, considered as optimal, the extraction results, that is, residual soluble COD, residual percentage of surfactant in the dilute phase and volume fraction of coacervate at equilibrium, were expressed in terms of temperature and initial surfactant concentration. For each parameter, the results obtained were modeled using the response surface methodology and represented on three‐dimensional diagrams. They show that the COD can be reduced to 10 and 15 mg O2/L, using Lutensol ON30 and Tergitol 15‐S‐7, respectively, under seawater temperature conditions. Finally, it was shown that the surfactant can be recycled.
