“…RSM reduces the number of experimental trials required to evaluate multiple variables and their interactions. The BoxeBehnken design (BBD) is widely used RSM (Ponmurugan et al, 2017) for optimization of spherical and revolving design; it consists of a central point and the middle points of the edges of the cube circumscribed on the sphere. It is a second order multivariate technique based on threeelevel fractional factorial design consisting of a full 2 2 factorial scattered into a balanced incomplete block design.…”

“…It is a second order multivariate technique based on threeelevel fractional factorial design consisting of a full 2 2 factorial scattered into a balanced incomplete block design. To investigate the behavior of the response surface for the response function (Y) using the secondeorder polynomial equation, a BBD is often preferred since interaction variable estimates are not completely confounded (Ponmurugan et al, 2017). The generalized response surface model is…”

A bacterium isolated from effluent of thermal paper industry and identified as Pseudomonas aeruginosa (PAb1) based on 16SrRNA gene sequence analysis which could grow on basal mineral salt medium upon bisphenol A, which functions as an exclusive carbon source. Physicochemical variables of thermal paper industry effluent noted were significantly greater than the typical limit due to pollution of the acquiring water systems. The mathematic kinetic models like Monod, Moser and Tesier models were applied for batch fermentation of bisphenol A degradation in basal salt medium and the half saturation coefficient (K S) and the regression coefficient R 2 using Monad, Moser and Tesier kinetic models registered as 9.947 g/L, 12.46 g/L and 14.14 g/L and 0.91, 0.94 and 0.84 respectively. Besides, the utmost specific growth rate mmax was witnessed as 0.841 h À1 for the P. aeruginosa (PAb1) regarding BPA degradation. Metabolic intermediates like phenol, acetophenone, and hydroquinone and p-hydroxybenzoic acid were also determined through the degradation process by GC-MS. The metabolic pathway of BPA degradation by the bacterial isolates was also designed in today's analysis. A probabilistic statistical model originated using Box-Behnken response surface methodology and process variables were optimized by nonlinear optimization.

“…The previously determined extraction conditions, time (30 min), temperature (30°C), dual‐frequency (20–40 kHz), ethanol concentration (29%), and (NH 4 ) 2 SO 2 (19%) were kept constant while ultrasonic power was varied (60‐300 W). The results in Figure 2e showed a maximum APS yield at 240 W with a decrease in yield beyond 240 W. The decrease in the APS yield when power exceeded 240 W could be ascribed to the exaggeration of the amplitude of the ultrasound wave thus inducing a vigorous generation of cavitation bubbles which reduces the transmission of ultrasonic energy into the cavitation field leading to a decrease in the APS yield (Ponmurugan et al, ). Therefore the optimal power of 240 W was chosen for subsequent experiments.…”

The study investigated the effect of dual‐frequency ultrasound‐assisted alcohol/salt aqueous two‐phase extraction and desalination on the yield, microstructure and antioxidant properties of Astragalus polysaccharides (APS). Extracts were desalinated for 10 (APS10), 20 (APS20), and 30 (APS30) minutes. A 28.40% experimental yield, well correlated to the response surface methodology predicted model was achieved. Thermodynamic parameters were non‐spontaneous, irreversible and endothermic. Moreover, ultrasound enhanced the desalination rate and did not alter the chemical structure in the APS. Fourier Transform Infrared Spectroscopy showed a similar spectrum in all the APS samples. High‐performance gel chromatography and scanning electron microscopy, respectively presented reduced molecular weights and altered microstructures in the samples. Monosaccharide analysis revealed the existence of xylose, mannose, galactose, glucose, arabinose, rhamnose, and ribose in the APS samples. Moreover, the APS20 showed strong hydroxyl and 2,2‐diphenyl‐1‐picrylhydrazyl radical scavenging activities, thus showing its potency in reducing oxidative stress. Hence, this study demonstrates that coupled ultrasound and alcohol/salt ATPS is a sustainable technique, which generates high yields of simultaneously extracted products. Practical applications Astragalus root has been used as an effective complementary treatment to conventional medicine owing to its rich nutraceutical composition and its numerous health attributes. Commercialization of Astragalus supplements into functional foods and nutraceuticals requires continuous exploration of novel, low cost and reproducible methods that retain their bioactivity. In this work, a synergized and bio‐compatible dual‐frequency ultrasound‐assisted alcohol/salt aqueous two‐phase system was used to extract and purify Astragalus polysaccharides. Application of this technique in the nutraceutical industry reduces treatment time, lowers bulk energy consumption hence reducing energy costs. It promotes the use of low‐cost, non‐hazardous bio‐based solvents in treatment processes thus considerably reducing extraction costs and environmental degradation. Findings from this study exhibit the practicability of this technique in industrial application. It equips biotechnologists with information on improved, sustainable and safer ways of extracting and enriching the quality of nutraceutical compounds.

High ultrasonic-assisted extraction technology (INEFU) was employed to extract the active components from natural materials (green coffee beans, Citrus madurensis, Centella asiatica, Laminaria Japonica). The extraction conditions were optimized by a response surface method and Box-Behnken design. The active component yields were obtained under the optimum parameters: ultrasound power (1800 watts), ultrasonication time, and particle size. After INEFU of natural materials (green coffee beans, Citrus madurensis, Centella asiatica and Laminaria Japonica) the products were analyzed with high performance liquid chromatography (HPLC). HPLC analysis showed that the four natural materials were composed of different combinations of vitamin C, polyphenols, chlorogenic acid, caffein, caffeic acid, asiaticoside and alginic acid. In addition, the INEFU results showed that natural materials can yield more active components during a simulated extraction process.
