“…Media originated from agro-industrial and/or domestic waste with high carbon availability and/or providing increased biosurfactant production and stability, such as bagasse and potato peels (24), rice bran oil residue (25) and residual frying oil (52) have been extensively investigated. These options comprise alternatives to nancially compete with traditional surfactants (47), which have established economies of scale and are produced in large quantities.…”

“…One of the most researched biosurfactant elds encompasses the use of renewable substrates, including agro-industrial waste (24,25), as well as parameter optimization through statistical models, i.e., response surface methodology (21). Furthermore, genetic strain manipulation (26, 27) and chemical synthesis or structural modi cations (28) have also become prominent elds of research.…”

It is of fundamental interest to research and develop innovative biotechnologies, as well as bioproducts that replace or are alternatives to those of non-renewable origin, such as biosurfactants in relation to traditional surfactants used in various sectors. Consequently, there are a large number of experimental studies addressing different subjects, especially with the use of bacteria of the genus Pseudomonas, however, there is a lack of work that demonstrates the evaluation of this science produced to date. Therefore, this article discusses the production of biosurfactants by Pseudomonas with the aim of surveying and analyzing experimental articles on this topic. To realize this, a systematic search was carried out with well-defined temporal space, databases and inclusion and exclusion criteria, based on metric studies that guided what information would be collected and the method of evaluation. Therefore, a large number of articles were selected, which demonstrated Pseudomonas aeruginosa as the bioagent mostly used in the tests, which aimed to improve the process in the area. Furthermore, interest in this field has increased over the years, predominantly in emerging market countries, where the most prominent authors on the topic are found. Therefore, it is necessary that there is an expansion of interest in the area to make the production of biosurfactants cheaper in areas that currently have greater development deficiencies, such as means of purifying the bioprocess and reducing foam formation in the bioprocess.

The As (III) uptake capacity of Fe impregnated AC greatly depends on availability of active surface sites of Iron Oxide, which is determined by the surface area of the anchoring particles. In this context, utilizing Al as a surface regulator, we proposed a process to attach linked fibrils of FeHO₂ with the objective of developing an adsorbent with enhanced As (III) adsorption capacity. The procedure was based on hydrothermal process using paddy husk based AC, and both Iron and aluminium ions in the test hydrolysis solution. By a dynamic approach that would enable an industrial-scale treatment, fixed column adsorption tests were conducted to enhance the generation of cleaner effluents and further study the primary mechanisms involved in the adsorption process. CCD was employed to evaluate the interactions between various operating process variables and their effects on the breakthrough time for optimization of As (III) adsorption process. The exhaust time was observed to rise with increasing dose, falling flow rate, and influent concentration. The CCD optimization result showed that the FeAlPBC was an efficient and cost effective adsorbent with a maximum response of 1681 min, when the independent parameters were retained at 15.0 g FeAlPBC dose, 500 µg/L influent concentrations, 2.0 mL/min flow rate, and a desirability value of 0.986. To further comprehend the primary adsorption mechanisms, the breakthrough curves were predicted by application of the test data in the Thomas, Adam-Bohart, Yoone-Nelson, and Advection diffusion models. The experimental results and Thomas and Advection diffusion models were in good agreement. 0.1 M NaOH solution was used to regenerate the columns. The FeAlPBC samples can be recycled upto four cycles with little to no reduction in adsorption capacity. Also, the TCLP test demonstrated that the used FeAlPBC were inert and could be put into landfills without risk. In conclusion, FeAlPBC is a strong contender for removing As (III) from potable water and has a wide range of potential future applications.

“…Industrial agro residues rich in fat and oil are raw materials of bioprocesses suitable for the production of biosurfactants, examples are the hydrolysate of animal fat and the residues of the palm oil refinery. There are valuable substrates for a multitude of fermenting microbes, including cooking oil (Shi et al, 2021), rice bran oil residues (Mishra et al, 2021), and plant-derived oils (sunflower, soybean, rapeseed, corn, and babassu oils) (Joy et al, 2019;Patowary et al, 2016;Radzuan et al, 2017). Oily residues offer low-cost lipid substrates with precise lipid-carbohydrate balance for microbial growth (Ibrahim et al, 2021;Mgbechidinma et al, 2023;Sohail;Jamil, 2020).…”

The literature describes several studies focused on the application of S. maltophilia in different areas of biotechnology. Due to its ease of interaction with numerous environments and living beings, this bacterium has an excellent adaptability, being able to convert different substrates into products of high environmental and technological interest. Stenotrophomonas maltophilia is a gram-negative, aerobic, ubiquitous, rod-shaped bacterium belonging to the class of gammaproteobacteria and can be found in various natural and anthropogenic environments, e.g. soil, water, sediments or in association with plants. Biosurfactants are an alternative, compatible with the environment, for the use of chemically synthesized surfactants, since it is a bioproduct obtained through the metabolism of microorganisms and plants. Like their synthetic counterparts, biosurfactants comprise a wide variety of chemical structures and also excellent surfactant properties. The literature presents a wide range of studies focused on the production of biosurfactant by S. maltophilia using several substrates, temperature conditions, pH, salinade and fermentation times. In addition, there is also a huge variety of application of these biosurfactants produced, which drives the incentive to study this microorganism in the production of biosurfactants.
